[HIP] CUDA identifier is unsupported in HIP. #1783

Closed NAThompson closed 2 years ago

NAThompson commented 4 years ago

I don't know whether this should be a github issue or not, but what is the policy on unimplemented CUDA identifiers in HIP?

Here are a few which I've encountered:

 warning: CUDA identifier is unsupported in HIP:
   cudaMemoryTypeManaged,
   cudaMemAdvise,
   cudaMemAdviseSetAccessedBy,
   cudaCpuDeviceId,
   cudaMemPrefetchAsync,
   cudaStreamPerThread,
   cudaLimitStackSize

Are these on the roadmap?

Also, if these do not make it into hipify-clang, do they have a natural translation into hip?

cudaMemoryTypeManaged is of CUDA 10.0; thus, I believe it is not of the first priority.

@mangupta, @gargrahul, what about the rest, which all are of CUDA 8.0 or even older?

I'm also interested in the functions cudaMemAdvise / cuMemAdvise with the corresponding data types cudaMemoryAdvise / CUmem_advise.

Closing this ticket as all mentioned unsupported cuda identifiers are implemented in HIP now.
