 connor (burnt/out) (UTC-8) | also packaging flash attention now because hopefully it supports fp8 training where PyTorch's implementation does not
why does it require so much memory to build? What is NVCC doing? | 16:09:28 |

| connor (burnt/out) (UTC-8) | Looks like the authors of Flash Attention are looking at support for fp8 (which comes with v3, currently only available for Hopper) for Ada series per their rebuttals on their paper: https://openreview.net/forum?id=tVConYid20&referrer=%5Bthe+profile+of+Tri+Dao%5D%28%2Fprofile%3Fid%3D~Tri_Dao1%29 | 16:53:06 |

| connor (burnt/out) (UTC-8) | pushed the changes I had locally for nix-cuda-test (https://github.com/ConnorBaker/nix-cuda-test), if anyone wants to play with transformer engine or flash attention. I'll probably work on upstreaming those at some indeterminate point in time, but I don't know if they'll work with what's in-tree right now | 03:59:10 |

| connor (burnt/out) (UTC-8) | SomeoneSerge (utc+3): are you aware of a clean, cross-platform way to handle patching the path to libcuda.so (as needed in https://github.com/NixOS/nixpkgs/pull/369495#issuecomment-2566002172)? Is it fair to assume that on non-NixOS systems, whatever wrapper people use (like nixGL or nixglhost) will add libcuda.so to LD_LIBRARY_PATH? | 04:00:43 |
