WebDec 7, 2024 · Known GPU issues. For GPU faiss, add and search API calls need to be restructured somewhat to handle massive inputs in some cases, due to 32/64 bit integer confusion in various places. 32 bit integer math is much faster on the GPU, and this fact sadly leaked to the CPU side of GPU faiss. This is on the TODO list.
