Integrated GPU not supported on Windows

[ggkountouras]

Questionnaire

1. Does ROCm works for you outside of Julia, e.g. C/C++/Python?

I haven't tried it. On Windows you can only install the HIP SDK (https://github.com/ROCm/rocm-install-on-windows), which is a subset of the full ROCm.

2. Post output of rocminfo.

rocminfo doesn't exist on Windows: ROCm/ROCm#4024 (comment)

3. Post output of AMDGPU.versioninfo() if possible.

2. Provide MWE to reproduce it (if possible).

Install Julia binaries from the recommended command (that uses the MSStore). ]add AMDGPU. using AMDGPU

Additional Context

AMDGPU.jl doesn't support iGPUs on Linux either, but there is a workaround: https://discourse.julialang.org/t/does-amdgpu-jl-support-integrated-graphics/130675

[simeonschaub]

These warnings just mean you don't have the ROCm SDK installed, you will have to install that manually, AMDGPU.jl only provides the device libraries as a jll. It should still be possible to install the full ROCm SDK on Windows, see https://github.com/ROCm/TheRock/blob/main/RELEASES.md, but not sure whether your hardware is supported.

Is AMDGPU.jl working besides these ROCm libraries, e.g. does ROCArray(rand(10)) .+ ROCArray(rand(10)) work?

[ggkountouras]

A jll can be included in an app made with PackageCompiler. Without a jll, you'd have to ship the entire ROCm SDK and JIT the rest of the app on the user's device.

https://github.com/ROCm/TheRock/blob/main/ROADMAP.md shows that no RDNA2 hardware is supported.

julia> ROCArray(rand(10)) .+ ROCArray(rand(10))
ERROR could not load library ""
The parameter is incorrect.

[jpsamaroo]

AMDGPU.versioninfo() is reporting HIP is missing, so no real code will work. Please install the ROCm SDK and verify that it does in fact work. We can address wrapping the SDK in a JLL as a separate matter.

https://github.com/ROCm/TheRock/blob/main/ROADMAP.md shows that no RDNA2 hardware is supported.

I wouldn't trust what AMD officially supports, I would try it for yourself first. Sometimes what is listed as not supported still works perfectly fine.

[ggkountouras]

I assumed that my iGPU is RDNA2, but it's RDNA3, so it should be officially supported. The shader version is gfx1103, not among the supported LLVM targets (gfx1100, gfx1101, gfx1102).

The AWS bucket (https://therock-nightly-tarball.s3.amazonaws.com/) contains releases for windows-gfx110X-dgpu, but not windows-gfx110X-igpu. windows-gfx120X-all exists.

I downloaded the discrete GPU version. ./bin/test_hip_api.exe returns HIP error 98: invalid device function. With ./bin/test_accumulator_t.exe 252/252 tests pass. I also tested some of the /bin/test_device_*.exe programs. They give HIP error: invalid device function file.

How can I make julia see the ROCm SDK? Are there environment variables for that?

[ggkountouras]

Talked to AMD, gfx1103 is WIP.
