Everything said about multi-GPU kernels, oldest first

Jul 29, 2026 bearish
Assertion Supported
Stuart: Multi-GPU compilers often produce kernels slower than baseline
“Two is to use compiler-based approaches, but we find these compilers, compilers to be quite suboptimal. They produce kernels that are sometimes slower than non-overlapped baselines”

Insight
Stuart: Multi-GPU optimization requires overlapping compute with remote memory prefetching
“For multi-GPU kernels a simple, a similar idea applies, except that you're overlapping computation with communication with other GPUs, such that when the current computation is done, the data for next computation is ready and fetched from remote GPU HPMs.”
