How is ISPC's support for AMD MI supercomputing accelerators, or Nvidia's A100s ? I feel like Hip, OneAPI, ISPC, etc. haven't improved anything over CUDA. Wit

With CUDA we had one proprietary API. Now we have 3-4.
- marmaduke 6y agoIspc used to support NVPTX (since it’s based on LLVM) but for obvious reasons they dropped it. I agree that OpenCL should have won but OTOH most of us have AVX2 or NEON to work with at least and things like ISPC make that trivial to write for, for the workloads where it matters.
