Phoronix: POCL Is Working On OpenCL-Over-CUDA With New Backend

POCL, the Portable Computing Language project, aiming to provide a portable OpenCL implementation for usage against different CPUs and back-ends, has been working on CUDA support...

That's really good news! Such an early state and they are already exceeding the performance of nvidias opencl driver in some benchmarks.

why isnt the nvidia driver already doing this?

Good OpenCL support would enable competition. Now everyone uses CUDA which is exclusively for NVIDIA.

True, but as a result, we only have CUDA code. A CUDA over OpenCL translation layer would be needed as well :/

A good thing with vulkan is that the SPIR-V shades are shared with OpenCL.

It's not like you are going to run CUDA software on Intel's GPU so, here is solution for running CUDA code on AMD: https://github.com/GPUOpen-Professio...pute-Tools/HIP

Beyond allowing people to run applications using OpenCL versions that aren't supported on particular hardware, I don't understand what the point of this is. Isn't OpenCL in itself supposed to be highly portable API allowing applications to run on a myriad of CPUs, GPUs, DSPs and FPGAs?

AFAIK there was a CUDA --> HSA translator thing, "boltzmann initiative" was it?
