| > millions of threads Really?! What OSs can handle that many native threads? Also, this seems quite similar to stochastic progressive drawing of pointclouds for realtime that has been done for > 15 years in the VFX industry with GPU shaders in a tiled/bucketed fashion, unless this isn't progressive maybe? (The fact it's been accepted for Siggraph likely indicates it's slightly different). |

| I believe they mean GPU threads. Plenty of cuda files in their repository. |

| ▲ | pixelesque 6 hours ago | parent [-] | | Fair enough, but that's then only absolutely max 1024 threads per SM, which wouldn't get anywhere near 1 million, given 5090 only has 192 SMs... Future proofing I guess... | | |
