He combines technical mastery with practical experiences, making complex concepts accessible and engaging. His prolific tweeting shows a passion for both educating and debating within the tech community.
Sebastian tweets so much, even his keyboard reminds him it needs a coffee break, but at least if you ever need a bedtime story on GPU architecture or UI lag, you’re covered for years!
Transforming complex concepts like CPU design and UI responsiveness into viral tweets with millions of views and tens of thousands of likes — proving that deep tech knowledge can indeed capture mainstream attention.
Sebastian’s life purpose revolves around advancing technology through thoughtful innovation and clear communication, empowering others to understand and appreciate the intricacies of modern computing and user experience.
He values precision, reliability, and efficiency — believing that technology should be both powerful and user-friendly, supported by transparency in security and honest discourse. He trusts in continual learning and the importance of sharing knowledge to foster progress.
His strengths lie in deep technical knowledge, clear communication of complex subjects, and a keen ability to spot inefficiencies and security issues. Sebastian’s prolific output shows his dedication and readiness to engage with a broad audience.
His high technical density and sometimes critical stance might overwhelm casual followers or invite heated debates that can distract from constructive discourse. The sheer volume of tweets risks diluting impact or causing follower fatigue.
To grow on X, Sebastian should leverage succinct thread storytelling combined with approachable language to invite broader engagement. Adding occasional personal anecdotes or visual aids could boost relatability and retention, while engaging actively with follower questions could build community rapport.
Fun fact: Sebastian’s early experience writing sky shaders gave him the perfect real-life answer to his son’s question about why the sky is blue — a true testament to his blend of expertise and family humor!

No gear change lag.\n+ Heats up fast in winter (heat pump). Can start heater remotely. Nice for skiing trips.\n+ No legal limit on idling. Can use AC while waiting in drive-tru, waiting a ferry or working in the car.\n\nWorse:\n- Long distance travel needs more+longer stops. Newest tech improves both, but our EV is 4 years old.\n- Slightly bit heavier so consumes tires a bit faster. First set (both summer + winter) are still good condition. Seems a minor concern.\n- Price was around 5000€ more than ICE car with equivalent features.\n- EV tech improves so fast that older EVs lose resale value fast.

Appends a 32-bit active bitmask + XY16 coordinate (= 8 bytes) to each material bin that exists in that tile. Each material bin has an atomic counter.\n\nMaterial shading uses persistent threads. (1) SIMD32 wave does atomic add to get material bin offset. Then it loads the 32-bit mask + XY16 (= 64-bit load). It does popcnt of the mask to get the active lane count. Each of those threads setups their pixel coordinate + material index in registers. Then if the wave is not yet full, we loop back to 1, filling rest of the lanes with next tile, etc. If the last tile mask doesn't fit, it's kept in a register for next pass.\n\nNow we shade the full wave of that material. Each persistent wave does this concurrently of course (atomic add guarantees they got different tiles to process). Tile locality is maintained perfectly (one tile is never scattered to multiple SIMD32s). L1$ utilization is good. \n\nOnce the tile is shaded and results written to memory, we go back to 1. If the last group didn't fit fully, it starts the loop (with already processed bits masked out).\n\nThis continues until atomic add returns an offset > bin size. SIMD32 returns in that case, and other persistent threads die similarly soon after. \n\nYou can kick processing of multiple materials in the same time, no need to put barriers between them. There's no races as no pixel is written more than once.\n\nI already had this idea years ago for our new compute shader based GPGPU renderer. Now that I have been reading Nvidia SER (shader execution reordering) documentations and investigating it, I wanted to share this old idea that doesn't require SER hardware to work. You can use it with any shader types and it only uses minimal extra RAM bandwidth.\n\nIf you have already implemented something similar, please comment in the thread below.","in_reply_to_user_id_str":null,"in_reply_to_status_id_str":null,"is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[11,196],"entities":{"hashtags":[],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[{"id_str":"91588455","name":"SIGKITTEN","screen_name":"SIGKITTEN","indices":[0,10]}]},"favorited":false,"in_reply_to_screen_name":"SIGKITTEN","lang":"en","retweeted":false,"fact_check":null,"id":"1986160904724009265","view_count":1171,"bookmark_count":1,"created_at":1762372635000,"favorite_count":2,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1985815834833441165","full_text":"@SIGKITTEN It's $50k for eight 5090s.

You know both sides have the same weight as the scale is equal.","in_reply_to_user_id_str":"3436615413","in_reply_to_status_id_str":"1986812619072712986","is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[0,162],"entities":{"hashtags":[],"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[]},"extended_entities":{"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}]},"favorited":false,"in_reply_to_screen_name":"SebAaltonen","lang":"en","possibly_sensitive":false,"possibly_sensitive_editable":true,"retweeted":false,"fact_check":null,"id":"1986700795216011429","view_count":1909,"bookmark_count":4,"created_at":1762501355000,"favorite_count":19,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1986699700720865293","full_text":"The Hyper RHI public interface was already suitable for threading.

Highest bits = chunk index, lowest bit is array index. Chunk array is 256 pointers = 2KB. That seems to be implemented fine.\n- It created a 65536 element fixed size freelist for each pool. 32-bit per element. That's 128KB per pool. Not great :(\n- The freelist is using a lockless CAS approach. That's why it bitpacks more stuff than just the 16-bit index in the freelist elements. That's good, but I don't think we can afford 128KB freelist per pool.\n- AI made the generation counters atomic<uint16>. This is actually not needed as deletes are batched and adds and deletes can't race due to external architecture. Not great to have atomic load for each data access. I want to get rid of this.\n- AI added safety checks for handle block index and handle index being larger than pool. These are unneeded as each handle comes from the pool. Blocks are never reclaimed (grows to peak), so a given block index is always true. Pool also never returns an index larger than the pool. ASSERT for debug builds would be a better approach (no runtime cost in release build) in case something catastrophical happens such as memory corruption for a handle.\n- Allocating a new block is protected by a mutex. Which is fine. This is a very uncommon operation, often only happening at start of the app or first level loads. Most of the time freelist provides a slot for the new item = lockless. \n\nSeems that there's no clear issues with the pool.

No gear change lag.\n+ Heats up fast in winter (heat pump). Can start heater remotely. Nice for skiing trips.\n+ No legal limit on idling. Can use AC while waiting in drive-tru, waiting a ferry or working in the car.\n\nWorse:\n- Long distance travel needs more+longer stops. Newest tech improves both, but our EV is 4 years old.\n- Slightly bit heavier so consumes tires a bit faster. First set (both summer + winter) are still good condition. Seems a minor concern.\n- Price was around 5000€ more than ICE car with equivalent features.\n- EV tech improves so fast that older EVs lose resale value fast.

Appends a 32-bit active bitmask + XY16 coordinate (= 8 bytes) to each material bin that exists in that tile. Each material bin has an atomic counter.\n\nMaterial shading uses persistent threads. (1) SIMD32 wave does atomic add to get material bin offset. Then it loads the 32-bit mask + XY16 (= 64-bit load). It does popcnt of the mask to get the active lane count. Each of those threads setups their pixel coordinate + material index in registers. Then if the wave is not yet full, we loop back to 1, filling rest of the lanes with next tile, etc. If the last tile mask doesn't fit, it's kept in a register for next pass.\n\nNow we shade the full wave of that material. Each persistent wave does this concurrently of course (atomic add guarantees they got different tiles to process). Tile locality is maintained perfectly (one tile is never scattered to multiple SIMD32s). L1$ utilization is good. \n\nOnce the tile is shaded and results written to memory, we go back to 1. If the last group didn't fit fully, it starts the loop (with already processed bits masked out).\n\nThis continues until atomic add returns an offset > bin size. SIMD32 returns in that case, and other persistent threads die similarly soon after. \n\nYou can kick processing of multiple materials in the same time, no need to put barriers between them. There's no races as no pixel is written more than once.\n\nI already had this idea years ago for our new compute shader based GPGPU renderer. Now that I have been reading Nvidia SER (shader execution reordering) documentations and investigating it, I wanted to share this old idea that doesn't require SER hardware to work. You can use it with any shader types and it only uses minimal extra RAM bandwidth.\n\nIf you have already implemented something similar, please comment in the thread below.","in_reply_to_user_id_str":null,"in_reply_to_status_id_str":null,"is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[11,196],"entities":{"hashtags":[],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[{"id_str":"91588455","name":"SIGKITTEN","screen_name":"SIGKITTEN","indices":[0,10]}]},"favorited":false,"in_reply_to_screen_name":"SIGKITTEN","lang":"en","retweeted":false,"fact_check":null,"id":"1986160904724009265","view_count":1171,"bookmark_count":1,"created_at":1762372635000,"favorite_count":2,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1985815834833441165","full_text":"@SIGKITTEN It's $50k for eight 5090s.

You know both sides have the same weight as the scale is equal.","in_reply_to_user_id_str":"3436615413","in_reply_to_status_id_str":"1986812619072712986","is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[0,162],"entities":{"hashtags":[],"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[]},"extended_entities":{"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}]},"favorited":false,"in_reply_to_screen_name":"SebAaltonen","lang":"en","possibly_sensitive":false,"possibly_sensitive_editable":true,"retweeted":false,"fact_check":null,"id":"1986700795216011429","view_count":1909,"bookmark_count":4,"created_at":1762501355000,"favorite_count":19,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1986699700720865293","full_text":"The Hyper RHI public interface was already suitable for threading.

Highest bits = chunk index, lowest bit is array index. Chunk array is 256 pointers = 2KB. That seems to be implemented fine.\n- It created a 65536 element fixed size freelist for each pool. 32-bit per element. That's 128KB per pool. Not great :(\n- The freelist is using a lockless CAS approach. That's why it bitpacks more stuff than just the 16-bit index in the freelist elements. That's good, but I don't think we can afford 128KB freelist per pool.\n- AI made the generation counters atomic<uint16>. This is actually not needed as deletes are batched and adds and deletes can't race due to external architecture. Not great to have atomic load for each data access. I want to get rid of this.\n- AI added safety checks for handle block index and handle index being larger than pool. These are unneeded as each handle comes from the pool. Blocks are never reclaimed (grows to peak), so a given block index is always true. Pool also never returns an index larger than the pool. ASSERT for debug builds would be a better approach (no runtime cost in release build) in case something catastrophical happens such as memory corruption for a handle.\n- Allocating a new block is protected by a mutex. Which is fine. This is a very uncommon operation, often only happening at start of the app or first level loads. Most of the time freelist provides a slot for the new item = lockless. \n\nSeems that there's no clear issues with the pool.

No gear change lag.\n+ Heats up fast in winter (heat pump). Can start heater remotely. Nice for skiing trips.\n+ No legal limit on idling. Can use AC while waiting in drive-tru, waiting a ferry or working in the car.\n\nWorse:\n- Long distance travel needs more+longer stops. Newest tech improves both, but our EV is 4 years old.\n- Slightly bit heavier so consumes tires a bit faster. First set (both summer + winter) are still good condition. Seems a minor concern.\n- Price was around 5000€ more than ICE car with equivalent features.\n- EV tech improves so fast that older EVs lose resale value fast.

Appends a 32-bit active bitmask + XY16 coordinate (= 8 bytes) to each material bin that exists in that tile. Each material bin has an atomic counter.\n\nMaterial shading uses persistent threads. (1) SIMD32 wave does atomic add to get material bin offset. Then it loads the 32-bit mask + XY16 (= 64-bit load). It does popcnt of the mask to get the active lane count. Each of those threads setups their pixel coordinate + material index in registers. Then if the wave is not yet full, we loop back to 1, filling rest of the lanes with next tile, etc. If the last tile mask doesn't fit, it's kept in a register for next pass.\n\nNow we shade the full wave of that material. Each persistent wave does this concurrently of course (atomic add guarantees they got different tiles to process). Tile locality is maintained perfectly (one tile is never scattered to multiple SIMD32s). L1$ utilization is good. \n\nOnce the tile is shaded and results written to memory, we go back to 1. If the last group didn't fit fully, it starts the loop (with already processed bits masked out).\n\nThis continues until atomic add returns an offset > bin size. SIMD32 returns in that case, and other persistent threads die similarly soon after. \n\nYou can kick processing of multiple materials in the same time, no need to put barriers between them. There's no races as no pixel is written more than once.\n\nI already had this idea years ago for our new compute shader based GPGPU renderer. Now that I have been reading Nvidia SER (shader execution reordering) documentations and investigating it, I wanted to share this old idea that doesn't require SER hardware to work. You can use it with any shader types and it only uses minimal extra RAM bandwidth.\n\nIf you have already implemented something similar, please comment in the thread below.","in_reply_to_user_id_str":null,"in_reply_to_status_id_str":null,"is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[11,196],"entities":{"hashtags":[],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[{"id_str":"91588455","name":"SIGKITTEN","screen_name":"SIGKITTEN","indices":[0,10]}]},"favorited":false,"in_reply_to_screen_name":"SIGKITTEN","lang":"en","retweeted":false,"fact_check":null,"id":"1986160904724009265","view_count":1171,"bookmark_count":1,"created_at":1762372635000,"favorite_count":2,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1985815834833441165","full_text":"@SIGKITTEN It's $50k for eight 5090s.

You know both sides have the same weight as the scale is equal.","in_reply_to_user_id_str":"3436615413","in_reply_to_status_id_str":"1986812619072712986","is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[0,162],"entities":{"hashtags":[],"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[]},"extended_entities":{"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}]},"favorited":false,"in_reply_to_screen_name":"SebAaltonen","lang":"en","possibly_sensitive":false,"possibly_sensitive_editable":true,"retweeted":false,"fact_check":null,"id":"1986700795216011429","view_count":1909,"bookmark_count":4,"created_at":1762501355000,"favorite_count":19,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1986699700720865293","full_text":"The Hyper RHI public interface was already suitable for threading.

Highest bits = chunk index, lowest bit is array index. Chunk array is 256 pointers = 2KB. That seems to be implemented fine.\n- It created a 65536 element fixed size freelist for each pool. 32-bit per element. That's 128KB per pool. Not great :(\n- The freelist is using a lockless CAS approach. That's why it bitpacks more stuff than just the 16-bit index in the freelist elements. That's good, but I don't think we can afford 128KB freelist per pool.\n- AI made the generation counters atomic<uint16>. This is actually not needed as deletes are batched and adds and deletes can't race due to external architecture. Not great to have atomic load for each data access. I want to get rid of this.\n- AI added safety checks for handle block index and handle index being larger than pool. These are unneeded as each handle comes from the pool. Blocks are never reclaimed (grows to peak), so a given block index is always true. Pool also never returns an index larger than the pool. ASSERT for debug builds would be a better approach (no runtime cost in release build) in case something catastrophical happens such as memory corruption for a handle.\n- Allocating a new block is protected by a mutex. Which is fine. This is a very uncommon operation, often only happening at start of the app or first level loads. Most of the time freelist provides a slot for the new item = lockless. \n\nSeems that there's no clear issues with the pool.

No gear change lag.\n+ Heats up fast in winter (heat pump). Can start heater remotely. Nice for skiing trips.\n+ No legal limit on idling. Can use AC while waiting in drive-tru, waiting a ferry or working in the car.\n\nWorse:\n- Long distance travel needs more+longer stops. Newest tech improves both, but our EV is 4 years old.\n- Slightly bit heavier so consumes tires a bit faster. First set (both summer + winter) are still good condition. Seems a minor concern.\n- Price was around 5000€ more than ICE car with equivalent features.\n- EV tech improves so fast that older EVs lose resale value fast.

Appends a 32-bit active bitmask + XY16 coordinate (= 8 bytes) to each material bin that exists in that tile. Each material bin has an atomic counter.\n\nMaterial shading uses persistent threads. (1) SIMD32 wave does atomic add to get material bin offset. Then it loads the 32-bit mask + XY16 (= 64-bit load). It does popcnt of the mask to get the active lane count. Each of those threads setups their pixel coordinate + material index in registers. Then if the wave is not yet full, we loop back to 1, filling rest of the lanes with next tile, etc. If the last tile mask doesn't fit, it's kept in a register for next pass.\n\nNow we shade the full wave of that material. Each persistent wave does this concurrently of course (atomic add guarantees they got different tiles to process). Tile locality is maintained perfectly (one tile is never scattered to multiple SIMD32s). L1$ utilization is good. \n\nOnce the tile is shaded and results written to memory, we go back to 1. If the last group didn't fit fully, it starts the loop (with already processed bits masked out).\n\nThis continues until atomic add returns an offset > bin size. SIMD32 returns in that case, and other persistent threads die similarly soon after. \n\nYou can kick processing of multiple materials in the same time, no need to put barriers between them. There's no races as no pixel is written more than once.\n\nI already had this idea years ago for our new compute shader based GPGPU renderer. Now that I have been reading Nvidia SER (shader execution reordering) documentations and investigating it, I wanted to share this old idea that doesn't require SER hardware to work. You can use it with any shader types and it only uses minimal extra RAM bandwidth.\n\nIf you have already implemented something similar, please comment in the thread below.","in_reply_to_user_id_str":null,"in_reply_to_status_id_str":null,"is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[11,196],"entities":{"hashtags":[],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[{"id_str":"91588455","name":"SIGKITTEN","screen_name":"SIGKITTEN","indices":[0,10]}]},"favorited":false,"in_reply_to_screen_name":"SIGKITTEN","lang":"en","retweeted":false,"fact_check":null,"id":"1986160904724009265","view_count":1171,"bookmark_count":1,"created_at":1762372635000,"favorite_count":2,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1985815834833441165","full_text":"@SIGKITTEN It's $50k for eight 5090s.

You know both sides have the same weight as the scale is equal.","in_reply_to_user_id_str":"3436615413","in_reply_to_status_id_str":"1986812619072712986","is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[0,162],"entities":{"hashtags":[],"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[]},"extended_entities":{"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}]},"favorited":false,"in_reply_to_screen_name":"SebAaltonen","lang":"en","possibly_sensitive":false,"possibly_sensitive_editable":true,"retweeted":false,"fact_check":null,"id":"1986700795216011429","view_count":1909,"bookmark_count":4,"created_at":1762501355000,"favorite_count":19,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1986699700720865293","full_text":"The Hyper RHI public interface was already suitable for threading.

Highest bits = chunk index, lowest bit is array index. Chunk array is 256 pointers = 2KB. That seems to be implemented fine.\n- It created a 65536 element fixed size freelist for each pool. 32-bit per element. That's 128KB per pool. Not great :(\n- The freelist is using a lockless CAS approach. That's why it bitpacks more stuff than just the 16-bit index in the freelist elements. That's good, but I don't think we can afford 128KB freelist per pool.\n- AI made the generation counters atomic<uint16>. This is actually not needed as deletes are batched and adds and deletes can't race due to external architecture. Not great to have atomic load for each data access. I want to get rid of this.\n- AI added safety checks for handle block index and handle index being larger than pool. These are unneeded as each handle comes from the pool. Blocks are never reclaimed (grows to peak), so a given block index is always true. Pool also never returns an index larger than the pool. ASSERT for debug builds would be a better approach (no runtime cost in release build) in case something catastrophical happens such as memory corruption for a handle.\n- Allocating a new block is protected by a mutex. Which is fine. This is a very uncommon operation, often only happening at start of the app or first level loads. Most of the time freelist provides a slot for the new item = lockless. \n\nSeems that there's no clear issues with the pool.

No gear change lag.\n+ Heats up fast in winter (heat pump). Can start heater remotely. Nice for skiing trips.\n+ No legal limit on idling. Can use AC while waiting in drive-tru, waiting a ferry or working in the car.\n\nWorse:\n- Long distance travel needs more+longer stops. Newest tech improves both, but our EV is 4 years old.\n- Slightly bit heavier so consumes tires a bit faster. First set (both summer + winter) are still good condition. Seems a minor concern.\n- Price was around 5000€ more than ICE car with equivalent features.\n- EV tech improves so fast that older EVs lose resale value fast.

Appends a 32-bit active bitmask + XY16 coordinate (= 8 bytes) to each material bin that exists in that tile. Each material bin has an atomic counter.\n\nMaterial shading uses persistent threads. (1) SIMD32 wave does atomic add to get material bin offset. Then it loads the 32-bit mask + XY16 (= 64-bit load). It does popcnt of the mask to get the active lane count. Each of those threads setups their pixel coordinate + material index in registers. Then if the wave is not yet full, we loop back to 1, filling rest of the lanes with next tile, etc. If the last tile mask doesn't fit, it's kept in a register for next pass.\n\nNow we shade the full wave of that material. Each persistent wave does this concurrently of course (atomic add guarantees they got different tiles to process). Tile locality is maintained perfectly (one tile is never scattered to multiple SIMD32s). L1$ utilization is good. \n\nOnce the tile is shaded and results written to memory, we go back to 1. If the last group didn't fit fully, it starts the loop (with already processed bits masked out).\n\nThis continues until atomic add returns an offset > bin size. SIMD32 returns in that case, and other persistent threads die similarly soon after. \n\nYou can kick processing of multiple materials in the same time, no need to put barriers between them. There's no races as no pixel is written more than once.\n\nI already had this idea years ago for our new compute shader based GPGPU renderer. Now that I have been reading Nvidia SER (shader execution reordering) documentations and investigating it, I wanted to share this old idea that doesn't require SER hardware to work. You can use it with any shader types and it only uses minimal extra RAM bandwidth.\n\nIf you have already implemented something similar, please comment in the thread below.","in_reply_to_user_id_str":null,"in_reply_to_status_id_str":null,"is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[11,196],"entities":{"hashtags":[],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[{"id_str":"91588455","name":"SIGKITTEN","screen_name":"SIGKITTEN","indices":[0,10]}]},"favorited":false,"in_reply_to_screen_name":"SIGKITTEN","lang":"en","retweeted":false,"fact_check":null,"id":"1986160904724009265","view_count":1171,"bookmark_count":1,"created_at":1762372635000,"favorite_count":2,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1985815834833441165","full_text":"@SIGKITTEN It's $50k for eight 5090s.

You know both sides have the same weight as the scale is equal.","in_reply_to_user_id_str":"3436615413","in_reply_to_status_id_str":"1986812619072712986","is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[0,162],"entities":{"hashtags":[],"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[]},"extended_entities":{"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}]},"favorited":false,"in_reply_to_screen_name":"SebAaltonen","lang":"en","possibly_sensitive":false,"possibly_sensitive_editable":true,"retweeted":false,"fact_check":null,"id":"1986700795216011429","view_count":1909,"bookmark_count":4,"created_at":1762501355000,"favorite_count":19,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1986699700720865293","full_text":"The Hyper RHI public interface was already suitable for threading.

Highest bits = chunk index, lowest bit is array index. Chunk array is 256 pointers = 2KB. That seems to be implemented fine.\n- It created a 65536 element fixed size freelist for each pool. 32-bit per element. That's 128KB per pool. Not great :(\n- The freelist is using a lockless CAS approach. That's why it bitpacks more stuff than just the 16-bit index in the freelist elements. That's good, but I don't think we can afford 128KB freelist per pool.\n- AI made the generation counters atomic<uint16>. This is actually not needed as deletes are batched and adds and deletes can't race due to external architecture. Not great to have atomic load for each data access. I want to get rid of this.\n- AI added safety checks for handle block index and handle index being larger than pool. These are unneeded as each handle comes from the pool. Blocks are never reclaimed (grows to peak), so a given block index is always true. Pool also never returns an index larger than the pool. ASSERT for debug builds would be a better approach (no runtime cost in release build) in case something catastrophical happens such as memory corruption for a handle.\n- Allocating a new block is protected by a mutex. Which is fine. This is a very uncommon operation, often only happening at start of the app or first level loads. Most of the time freelist provides a slot for the new item = lockless. \n\nSeems that there's no clear issues with the pool.

No gear change lag.\n+ Heats up fast in winter (heat pump). Can start heater remotely. Nice for skiing trips.\n+ No legal limit on idling. Can use AC while waiting in drive-tru, waiting a ferry or working in the car.\n\nWorse:\n- Long distance travel needs more+longer stops. Newest tech improves both, but our EV is 4 years old.\n- Slightly bit heavier so consumes tires a bit faster. First set (both summer + winter) are still good condition. Seems a minor concern.\n- Price was around 5000€ more than ICE car with equivalent features.\n- EV tech improves so fast that older EVs lose resale value fast.

Appends a 32-bit active bitmask + XY16 coordinate (= 8 bytes) to each material bin that exists in that tile. Each material bin has an atomic counter.\n\nMaterial shading uses persistent threads. (1) SIMD32 wave does atomic add to get material bin offset. Then it loads the 32-bit mask + XY16 (= 64-bit load). It does popcnt of the mask to get the active lane count. Each of those threads setups their pixel coordinate + material index in registers. Then if the wave is not yet full, we loop back to 1, filling rest of the lanes with next tile, etc. If the last tile mask doesn't fit, it's kept in a register for next pass.\n\nNow we shade the full wave of that material. Each persistent wave does this concurrently of course (atomic add guarantees they got different tiles to process). Tile locality is maintained perfectly (one tile is never scattered to multiple SIMD32s). L1$ utilization is good. \n\nOnce the tile is shaded and results written to memory, we go back to 1. If the last group didn't fit fully, it starts the loop (with already processed bits masked out).\n\nThis continues until atomic add returns an offset > bin size. SIMD32 returns in that case, and other persistent threads die similarly soon after. \n\nYou can kick processing of multiple materials in the same time, no need to put barriers between them. There's no races as no pixel is written more than once.\n\nI already had this idea years ago for our new compute shader based GPGPU renderer. Now that I have been reading Nvidia SER (shader execution reordering) documentations and investigating it, I wanted to share this old idea that doesn't require SER hardware to work.

Highest bits = chunk index, lowest bit is array index. Chunk array is 256 pointers = 2KB. That seems to be implemented fine.\n- It created a 65536 element fixed size freelist for each pool. 32-bit per element. That's 128KB per pool. Not great :(\n- The freelist is using a lockless CAS approach. That's why it bitpacks more stuff than just the 16-bit index in the freelist elements. That's good, but I don't think we can afford 128KB freelist per pool.\n- AI made the generation counters atomic<uint16>. This is actually not needed as deletes are batched and adds and deletes can't race due to external architecture. Not great to have atomic load for each data access. I want to get rid of this.\n- AI added safety checks for handle block index and handle index being larger than pool. These are unneeded as each handle comes from the pool. Blocks are never reclaimed (grows to peak), so a given block index is always true. Pool also never returns an index larger than the pool. ASSERT for debug builds would be a better approach (no runtime cost in release build) in case something catastrophical happens such as memory corruption for a handle.\n- Allocating a new block is protected by a mutex. Which is fine. This is a very uncommon operation, often only happening at start of the app or first level loads. Most of the time freelist provides a slot for the new item = lockless. \n\nSeems that there's no clear issues with the pool.

No gear change lag.\n+ Heats up fast in winter (heat pump). Can start heater remotely. Nice for skiing trips.\n+ No legal limit on idling. Can use AC while waiting in drive-tru, waiting a ferry or working in the car.\n\nWorse:\n- Long distance travel needs more+longer stops. Newest tech improves both, but our EV is 4 years old.\n- Slightly bit heavier so consumes tires a bit faster. First set (both summer + winter) are still good condition. Seems a minor concern.\n- Price was around 5000€ more than ICE car with equivalent features.\n- EV tech improves so fast that older EVs lose resale value fast.

Appends a 32-bit active bitmask + XY16 coordinate (= 8 bytes) to each material bin that exists in that tile. Each material bin has an atomic counter.\n\nMaterial shading uses persistent threads. (1) SIMD32 wave does atomic add to get material bin offset. Then it loads the 32-bit mask + XY16 (= 64-bit load). It does popcnt of the mask to get the active lane count. Each of those threads setups their pixel coordinate + material index in registers. Then if the wave is not yet full, we loop back to 1, filling rest of the lanes with next tile, etc. If the last tile mask doesn't fit, it's kept in a register for next pass.\n\nNow we shade the full wave of that material. Each persistent wave does this concurrently of course (atomic add guarantees they got different tiles to process). Tile locality is maintained perfectly (one tile is never scattered to multiple SIMD32s). L1$ utilization is good. \n\nOnce the tile is shaded and results written to memory, we go back to 1. If the last group didn't fit fully, it starts the loop (with already processed bits masked out).\n\nThis continues until atomic add returns an offset > bin size. SIMD32 returns in that case, and other persistent threads die similarly soon after. \n\nYou can kick processing of multiple materials in the same time, no need to put barriers between them. There's no races as no pixel is written more than once.\n\nI already had this idea years ago for our new compute shader based GPGPU renderer. Now that I have been reading Nvidia SER (shader execution reordering) documentations and investigating it, I wanted to share this old idea that doesn't require SER hardware to work. You can use it with any shader types and it only uses minimal extra RAM bandwidth.\n\nIf you have already implemented something similar, please comment in the thread below.","in_reply_to_user_id_str":null,"in_reply_to_status_id_str":null,"is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[11,196],"entities":{"hashtags":[],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[{"id_str":"91588455","name":"SIGKITTEN","screen_name":"SIGKITTEN","indices":[0,10]}]},"favorited":false,"in_reply_to_screen_name":"SIGKITTEN","lang":"en","retweeted":false,"fact_check":null,"id":"1986160904724009265","view_count":1171,"bookmark_count":1,"created_at":1762372635000,"favorite_count":2,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1985815834833441165","full_text":"@SIGKITTEN It's $50k for eight 5090s.

You know both sides have the same weight as the scale is equal.","in_reply_to_user_id_str":"3436615413","in_reply_to_status_id_str":"1986812619072712986","is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[0,162],"entities":{"hashtags":[],"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[]},"extended_entities":{"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}]},"favorited":false,"in_reply_to_screen_name":"SebAaltonen","lang":"en","possibly_sensitive":false,"possibly_sensitive_editable":true,"retweeted":false,"fact_check":null,"id":"1986700795216011429","view_count":1909,"bookmark_count":4,"created_at":1762501355000,"favorite_count":19,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1986699700720865293","full_text":"The Hyper RHI public interface was already suitable for threading.

Highest bits = chunk index, lowest bit is array index. Chunk array is 256 pointers = 2KB. That seems to be implemented fine.\n- It created a 65536 element fixed size freelist for each pool. 32-bit per element. That's 128KB per pool. Not great :(\n- The freelist is using a lockless CAS approach. That's why it bitpacks more stuff than just the 16-bit index in the freelist elements. That's good, but I don't think we can afford 128KB freelist per pool.\n- AI made the generation counters atomic<uint16>. This is actually not needed as deletes are batched and adds and deletes can't race due to external architecture. Not great to have atomic load for each data access. I want to get rid of this.\n- AI added safety checks for handle block index and handle index being larger than pool. These are unneeded as each handle comes from the pool. Blocks are never reclaimed (grows to peak), so a given block index is always true. Pool also never returns an index larger than the pool. ASSERT for debug builds would be a better approach (no runtime cost in release build) in case something catastrophical happens such as memory corruption for a handle.\n- Allocating a new block is protected by a mutex. Which is fine. This is a very uncommon operation, often only happening at start of the app or first level loads. Most of the time freelist provides a slot for the new item = lockless. \n\nSeems that there's no clear issues with the pool.

No gear change lag.\n+ Heats up fast in winter (heat pump). Can start heater remotely. Nice for skiing trips.\n+ No legal limit on idling. Can use AC while waiting in drive-tru, waiting a ferry or working in the car.\n\nWorse:\n- Long distance travel needs more+longer stops. Newest tech improves both, but our EV is 4 years old.\n- Slightly bit heavier so consumes tires a bit faster. First set (both summer + winter) are still good condition. Seems a minor concern.\n- Price was around 5000€ more than ICE car with equivalent features.\n- EV tech improves so fast that older EVs lose resale value fast.

Appends a 32-bit active bitmask + XY16 coordinate (= 8 bytes) to each material bin that exists in that tile. Each material bin has an atomic counter.\n\nMaterial shading uses persistent threads. (1) SIMD32 wave does atomic add to get material bin offset. Then it loads the 32-bit mask + XY16 (= 64-bit load). It does popcnt of the mask to get the active lane count. Each of those threads setups their pixel coordinate + material index in registers. Then if the wave is not yet full, we loop back to 1, filling rest of the lanes with next tile, etc. If the last tile mask doesn't fit, it's kept in a register for next pass.\n\nNow we shade the full wave of that material. Each persistent wave does this concurrently of course (atomic add guarantees they got different tiles to process). Tile locality is maintained perfectly (one tile is never scattered to multiple SIMD32s). L1$ utilization is good. \n\nOnce the tile is shaded and results written to memory, we go back to 1. If the last group didn't fit fully, it starts the loop (with already processed bits masked out).\n\nThis continues until atomic add returns an offset > bin size. SIMD32 returns in that case, and other persistent threads die similarly soon after. \n\nYou can kick processing of multiple materials in the same time, no need to put barriers between them. There's no races as no pixel is written more than once.\n\nI already had this idea years ago for our new compute shader based GPGPU renderer. Now that I have been reading Nvidia SER (shader execution reordering) documentations and investigating it, I wanted to share this old idea that doesn't require SER hardware to work. You can use it with any shader types and it only uses minimal extra RAM bandwidth.\n\nIf you have already implemented something similar, please comment in the thread below.","in_reply_to_user_id_str":null,"in_reply_to_status_id_str":null,"is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[11,196],"entities":{"hashtags":[],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[{"id_str":"91588455","name":"SIGKITTEN","screen_name":"SIGKITTEN","indices":[0,10]}]},"favorited":false,"in_reply_to_screen_name":"SIGKITTEN","lang":"en","retweeted":false,"fact_check":null,"id":"1986160904724009265","view_count":1171,"bookmark_count":1,"created_at":1762372635000,"favorite_count":2,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1985815834833441165","full_text":"@SIGKITTEN It's $50k for eight 5090s.

You know both sides have the same weight as the scale is equal.","in_reply_to_user_id_str":"3436615413","in_reply_to_status_id_str":"1986812619072712986","is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[0,162],"entities":{"hashtags":[],"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[]},"extended_entities":{"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}]},"favorited":false,"in_reply_to_screen_name":"SebAaltonen","lang":"en","possibly_sensitive":false,"possibly_sensitive_editable":true,"retweeted":false,"fact_check":null,"id":"1986700795216011429","view_count":1909,"bookmark_count":4,"created_at":1762501355000,"favorite_count":19,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1986699700720865293","full_text":"The Hyper RHI public interface was already suitable for threading.

Highest bits = chunk index, lowest bit is array index. Chunk array is 256 pointers = 2KB. That seems to be implemented fine.\n- It created a 65536 element fixed size freelist for each pool. 32-bit per element. That's 128KB per pool. Not great :(\n- The freelist is using a lockless CAS approach. That's why it bitpacks more stuff than just the 16-bit index in the freelist elements. That's good, but I don't think we can afford 128KB freelist per pool.\n- AI made the generation counters atomic<uint16>. This is actually not needed as deletes are batched and adds and deletes can't race due to external architecture. Not great to have atomic load for each data access. I want to get rid of this.\n- AI added safety checks for handle block index and handle index being larger than pool. These are unneeded as each handle comes from the pool. Blocks are never reclaimed (grows to peak), so a given block index is always true. Pool also never returns an index larger than the pool. ASSERT for debug builds would be a better approach (no runtime cost in release build) in case something catastrophical happens such as memory corruption for a handle.\n- Allocating a new block is protected by a mutex. Which is fine. This is a very uncommon operation, often only happening at start of the app or first level loads. Most of the time freelist provides a slot for the new item = lockless. \n\nSeems that there's no clear issues with the pool.

No gear change lag.\n+ Heats up fast in winter (heat pump). Can start heater remotely. Nice for skiing trips.\n+ No legal limit on idling. Can use AC while waiting in drive-tru, waiting a ferry or working in the car.\n\nWorse:\n- Long distance travel needs more+longer stops. Newest tech improves both, but our EV is 4 years old.\n- Slightly bit heavier so consumes tires a bit faster. First set (both summer + winter) are still good condition. Seems a minor concern.\n- Price was around 5000€ more than ICE car with equivalent features.\n- EV tech improves so fast that older EVs lose resale value fast.

Appends a 32-bit active bitmask + XY16 coordinate (= 8 bytes) to each material bin that exists in that tile. Each material bin has an atomic counter.\n\nMaterial shading uses persistent threads. (1) SIMD32 wave does atomic add to get material bin offset. Then it loads the 32-bit mask + XY16 (= 64-bit load). It does popcnt of the mask to get the active lane count. Each of those threads setups their pixel coordinate + material index in registers. Then if the wave is not yet full, we loop back to 1, filling rest of the lanes with next tile, etc. If the last tile mask doesn't fit, it's kept in a register for next pass.\n\nNow we shade the full wave of that material. Each persistent wave does this concurrently of course (atomic add guarantees they got different tiles to process). Tile locality is maintained perfectly (one tile is never scattered to multiple SIMD32s). L1$ utilization is good. \n\nOnce the tile is shaded and results written to memory, we go back to 1. If the last group didn't fit fully, it starts the loop (with already processed bits masked out).\n\nThis continues until atomic add returns an offset > bin size. SIMD32 returns in that case, and other persistent threads die similarly soon after. \n\nYou can kick processing of multiple materials in the same time, no need to put barriers between them. There's no races as no pixel is written more than once.\n\nI already had this idea years ago for our new compute shader based GPGPU renderer. Now that I have been reading Nvidia SER (shader execution reordering) documentations and investigating it, I wanted to share this old idea that doesn't require SER hardware to work. You can use it with any shader types and it only uses minimal extra RAM bandwidth.\n\nIf you have already implemented something similar, please comment in the thread below.","in_reply_to_user_id_str":null,"in_reply_to_status_id_str":null,"is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[11,196],"entities":{"hashtags":[],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[{"id_str":"91588455","name":"SIGKITTEN","screen_name":"SIGKITTEN","indices":[0,10]}]},"favorited":false,"in_reply_to_screen_name":"SIGKITTEN","lang":"en","retweeted":false,"fact_check":null,"id":"1986160904724009265","view_count":1171,"bookmark_count":1,"created_at":1762372635000,"favorite_count":2,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1985815834833441165","full_text":"@SIGKITTEN It's $50k for eight 5090s.

You know both sides have the same weight as the scale is equal.","in_reply_to_user_id_str":"3436615413","in_reply_to_status_id_str":"1986812619072712986","is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[0,162],"entities":{"hashtags":[],"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[]},"extended_entities":{"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}]},"favorited":false,"in_reply_to_screen_name":"SebAaltonen","lang":"en","possibly_sensitive":false,"possibly_sensitive_editable":true,"retweeted":false,"fact_check":null,"id":"1986700795216011429","view_count":1909,"bookmark_count":4,"created_at":1762501355000,"favorite_count":19,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1986699700720865293","full_text":"The Hyper RHI public interface was already suitable for threading.

Highest bits = chunk index, lowest bit is array index. Chunk array is 256 pointers = 2KB. That seems to be implemented fine.\n- It created a 65536 element fixed size freelist for each pool. 32-bit per element. That's 128KB per pool. Not great :(\n- The freelist is using a lockless CAS approach. That's why it bitpacks more stuff than just the 16-bit index in the freelist elements. That's good, but I don't think we can afford 128KB freelist per pool.\n- AI made the generation counters atomic<uint16>. This is actually not needed as deletes are batched and adds and deletes can't race due to external architecture. Not great to have atomic load for each data access. I want to get rid of this.\n- AI added safety checks for handle block index and handle index being larger than pool. These are unneeded as each handle comes from the pool. Blocks are never reclaimed (grows to peak), so a given block index is always true. Pool also never returns an index larger than the pool. ASSERT for debug builds would be a better approach (no runtime cost in release build) in case something catastrophical happens such as memory corruption for a handle.\n- Allocating a new block is protected by a mutex. Which is fine. This is a very uncommon operation, often only happening at start of the app or first level loads. Most of the time freelist provides a slot for the new item = lockless. \n\nSeems that there's no clear issues with the pool.

No gear change lag.\n+ Heats up fast in winter (heat pump). Can start heater remotely. Nice for skiing trips.\n+ No legal limit on idling. Can use AC while waiting in drive-tru, waiting a ferry or working in the car.\n\nWorse:\n- Long distance travel needs more+longer stops. Newest tech improves both, but our EV is 4 years old.\n- Slightly bit heavier so consumes tires a bit faster. First set (both summer + winter) are still good condition. Seems a minor concern.\n- Price was around 5000€ more than ICE car with equivalent features.\n- EV tech improves so fast that older EVs lose resale value fast.

Appends a 32-bit active bitmask + XY16 coordinate (= 8 bytes) to each material bin that exists in that tile. Each material bin has an atomic counter.\n\nMaterial shading uses persistent threads. (1) SIMD32 wave does atomic add to get material bin offset. Then it loads the 32-bit mask + XY16 (= 64-bit load). It does popcnt of the mask to get the active lane count. Each of those threads setups their pixel coordinate + material index in registers. Then if the wave is not yet full, we loop back to 1, filling rest of the lanes with next tile, etc. If the last tile mask doesn't fit, it's kept in a register for next pass.\n\nNow we shade the full wave of that material. Each persistent wave does this concurrently of course (atomic add guarantees they got different tiles to process). Tile locality is maintained perfectly (one tile is never scattered to multiple SIMD32s). L1$ utilization is good. \n\nOnce the tile is shaded and results written to memory, we go back to 1. If the last group didn't fit fully, it starts the loop (with already processed bits masked out).\n\nThis continues until atomic add returns an offset > bin size. SIMD32 returns in that case, and other persistent threads die similarly soon after. \n\nYou can kick processing of multiple materials in the same time, no need to put barriers between them. There's no races as no pixel is written more than once.\n\nI already had this idea years ago for our new compute shader based GPGPU renderer. Now that I have been reading Nvidia SER (shader execution reordering) documentations and investigating it, I wanted to share this old idea that doesn't require SER hardware to work. You can use it with any shader types and it only uses minimal extra RAM bandwidth.\n\nIf you have already implemented something similar, please comment in the thread below.","in_reply_to_user_id_str":null,"in_reply_to_status_id_str":null,"is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[11,196],"entities":{"hashtags":[],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[{"id_str":"91588455","name":"SIGKITTEN","screen_name":"SIGKITTEN","indices":[0,10]}]},"favorited":false,"in_reply_to_screen_name":"SIGKITTEN","lang":"en","retweeted":false,"fact_check":null,"id":"1986160904724009265","view_count":1171,"bookmark_count":1,"created_at":1762372635000,"favorite_count":2,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1985815834833441165","full_text":"@SIGKITTEN It's $50k for eight 5090s.

You know both sides have the same weight as the scale is equal.","in_reply_to_user_id_str":"3436615413","in_reply_to_status_id_str":"1986812619072712986","is_quote_status":0,"is_ai":null,"ai_score":null},{"bookmarked":false,"display_text_range":[0,162],"entities":{"hashtags":[],"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}],"symbols":[],"timestamps":[],"urls":[],"user_mentions":[]},"extended_entities":{"media":[{"display_url":"pic.x.com/D1zt3NF9vy","expanded_url":"https://x.com/SebAaltonen/status/1986700795216011429/photo/1","id_str":"1986700572641087488","indices":[163,186],"media_key":"3_1986700572641087488","media_url_https":"https://pbs.twimg.com/media/G5ItpRNWUAAwQur.jpg","type":"photo","url":"https://t.co/D1zt3NF9vy","ext_media_availability":{"status":"Available"},"features":{"large":{"faces":[{"x":220,"y":445,"h":81,"w":81}]},"medium":{"faces":[{"x":154,"y":312,"h":56,"w":56}]},"small":{"faces":[{"x":87,"y":176,"h":32,"w":32}]},"orig":{"faces":[{"x":220,"y":445,"h":81,"w":81}]}},"sizes":{"large":{"h":960,"w":1710,"resize":"fit"},"medium":{"h":674,"w":1200,"resize":"fit"},"small":{"h":382,"w":680,"resize":"fit"},"thumb":{"h":150,"w":150,"resize":"crop"}},"original_info":{"height":960,"width":1710,"focus_rects":[{"x":0,"y":0,"w":1710,"h":958},{"x":375,"y":0,"w":960,"h":960},{"x":434,"y":0,"w":842,"h":960},{"x":615,"y":0,"w":480,"h":960},{"x":0,"y":0,"w":1710,"h":960}]},"media_results":{"result":{"media_key":"3_1986700572641087488"}}}]},"favorited":false,"in_reply_to_screen_name":"SebAaltonen","lang":"en","possibly_sensitive":false,"possibly_sensitive_editable":true,"retweeted":false,"fact_check":null,"id":"1986700795216011429","view_count":1909,"bookmark_count":4,"created_at":1762501355000,"favorite_count":19,"quote_count":0,"reply_count":1,"retweet_count":0,"user_id_str":"3436615413","conversation_id_str":"1986699700720865293","full_text":"The Hyper RHI public interface was already suitable for threading.

Highest bits = chunk index, lowest bit is array index. Chunk array is 256 pointers = 2KB. That seems to be implemented fine.\n- It created a 65536 element fixed size freelist for each pool. 32-bit per element. That's 128KB per pool. Not great :(\n- The freelist is using a lockless CAS approach. That's why it bitpacks more stuff than just the 16-bit index in the freelist elements. That's good, but I don't think we can afford 128KB freelist per pool.\n- AI made the generation counters atomic<uint16>. This is actually not needed as deletes are batched and adds and deletes can't race due to external architecture. Not great to have atomic load for each data access. I want to get rid of this.\n- AI added safety checks for handle block index and handle index being larger than pool. These are unneeded as each handle comes from the pool. Blocks are never reclaimed (grows to peak), so a given block index is always true. Pool also never returns an index larger than the pool. ASSERT for debug builds would be a better approach (no runtime cost in release build) in case something catastrophical happens such as memory corruption for a handle.\n- Allocating a new block is protected by a mutex. Which is fine. This is a very uncommon operation, often only happening at start of the app or first level loads. Most of the time freelist provides a slot for the new item = lockless. \n\nSeems that there's no clear issues with the pool.
