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.”

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”
