HIP copies very slow #1491

jpietarilagraham commented 1 year ago

Similar to the problem the cuda dma branch fixed for cuda, we need a fix for slow copies on AMD GPUs.

We need people to cherry-pick the changes of the cuda module into the hip module from this PR https://gitlab.com/StanfordLegion/legion/-/merge_requests/697, then the hip DMA should work.

There was a brief discussion on legion meeting this Thursday (08/03) and I believe @pmccormick is going to take the "initial look" at what needs to be done.
