GPU offloading not working on system with AMD 5900HX CPU

[vlasky]

I'm running llamafile 0.8.1 on a Windows 10 mini PC with a AMD Ryzen 9 5900HX CPU

CPU Architecture: AMD Cezanne (Zen 3, Ryzen 5000)
GPU: AMD Radeon RX Vega 8

The mini PC has 64GB RAM installed.

When I enable llamafile GPU support with -ngl 9999, it exits with the error

ggml_cuda_compute_forward: RMS_NORM failed
CUDA error: invalid device function
  current device: 0, in function ggml_cuda_compute_forward at ggml-cuda.cu:11444
  err
GGML_ASSERT: ggml-cuda.cu:9198: !"CUDA error"

My command line is:

llamafile-0.8.1.exe -ngl 9999 -m dolphin-2.9-llama3-8b-Q5_K_M.gguf

I have also tried re-running after installing the AMD HIP SDK but this made no difference.
Contrary to the runtime messages, amdclang++.exe was in my Windows PATH.

Hey I believe integrated GPU are not supported, probably better to run on CPU at this time, by passing -ngl 0 instead of 9999

Also I have seen a few open issues with the same error/warning at the start when using AMD, so am not sure if I should open a new issues.
The line that says : get_rocm_bin_path: note: amdclang++.exe not found on $PATH
The actually file located there is named clang++.exe , in Windows, however on Linux is called amdclang++.exe

Perhaps there could be an Operating System check before looking for amdclang++ or clang++.
or maybe it is something else

OK. I was curious to know whether additional acceleration could be obtained by combining the iGPU with the CPU.

In any case, I reckon the docs should explicitly state that AMD iGPUs are not supported (if they're not). Ideally, llamafile should also report this at runtime.

Also I have seen a few open issues with the same error/warning at the start when using AMD, so am not sure if I should open a new issues.

Yes. I copied clang++.exe to amdclang++.exe to overcome this. Both executables were in the $PATH, but the get_rocm_bin_path: note: amdclang++.exe not found on $PATH message still appeared.
