AMDGPU on windows

[meysamrajabi95]

Based on the new update of the ROCm driver: [https://rocm.docs.amd.com/en/latest/deploy/windows/quick_start.html]

now AMDGPU should work on Windows too, right?

In theory yes, but would require changes to AMDGPU.jl package.
Mainly (or at least) adapting to newer versions of LLVM (ROCm 5.5 uses LLVM 16) and taking into account Windows directory structure during initialization.

But Windows support is definitely on a list

[meysamrajabi95]

Thank you! So, I still can not use the AMDGPU package on Windows and I should wait for the new version of AMDGPU.jl ?
Because I set up ROCm and still got the "No GPU devices detected" error.

Because it does not know about Windows directory structure and assumes Linux.
If you can adapt bindeps_setup function that loads ROCm libraries to Windows that could be a start.

You'd need to change default paths (from /opt/rocm on Linux to whatever it is on Windows) and load .dll instead .so.

Also, I'm not sure about ROCm HSA library being available on Windows, which is one of the core libraries.

If you did everything correctly, AMDGPU.versioninfo() should give you paths to all libraries that it loaded:

julia> AMDGPU.versioninfo()

    @ /opt/rocm-5.4.3/lib/libhsa-runtime64.so

now Im getting this:
julia> AMDGPU.versioninfo() ROCm provided by: system [-] HSA Runtime [-] ld.lld [-] ROCm-Device-Libs [-] HIP Runtime [-] rocBLAS [-] rocSOLVER [-] rocALUTION [-] rocSPARSE [-] rocRAND [-] rocFFT [-] MIOpen

but I believe I have all this lib in the ROCm driver installed path:

But I don't know how to add these to Julia/AMDGPU package so I don't have this error

Is there a way to install dynamic libraries? .lib is a static library and won't work.
There should be .dlls instead.

[vchuravy]

I think those .lib are import libraries not static archives. The question is are there dll somewhere else?

Good news is that according to the LLVM docs the triple amdhsa is supported on windows if "AMD’s PAL runtime using the pal-amdhsa loader on Windows."

[vchuravy]

I just used wine to unpack the installer on Linux and as expected the dll are in the bin folder.

AMDGPU 0.8 has initial Windows support. Make sure to check requirements.

This is awesome. Thanks
