Ispc 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 AVX

Ispc 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.
