Speaking of potentially obsolete sanctions, conferences have been on hold so I might be hanging on to a few more of them past their due date. Does anyone have fresh experiences with these? ------------------ AMD GPUs (2014): Waiting for GPGPU support from Adobe and Blender that was supposed to be operational (Adobe) or getting there (Blender) but never landed. AMD GPUs (2016): I burned an entire semester trying to port CUDA code to OpenCL only to run into bug after bug after bug. Lockups, black screens (no framebuffers were supposed to be involved but bugs find a way), leaks, stalls which were difficult to attribute, unscruitable errors leading to abandoned threads with pleading users from years past with no reply. I finally cracked when after a long day of "I swear this should work I have no idea how the changes I make correspond to the bugs I see" I ran my ailing OpenCL code on a weaker NVidia card, and it Just Worked. Not only did it just work, it was 10x faster. Even though the card was like 2 generations older, and I was using OpenCL, which NVidia had every reason to sandbag, but they were still winning at. Oh, and the debugging tools actually worked, too. I was persuaded to sell my red cards, eat the ebay tax, eat the nvidia tax, and buy green from then on. Time has passed since 2016, though. ROCm looks good and AMD has money now, so maybe they can afford to pay people to fix bugs. I want to see someone running Blender and a modern ML framework or two before I retire the sanctions, though. Anyone have fresh intuition here? Numba CUDA (2018): I spent two weeks working through a succession of problems that I eventually resolved in two days by just using CUDA C++. Numba CUDA only worked with year-stale CUDA, it copied float8s over a float4 array despite having access to triply redundant type specs, the mechanism to pass buffers between kernels always forced copy off GPU, and one more that I forget. I made patches for the first three and gave up on the last one before fixing. Has anyone used it recently? Is it in better shape these days?
