CUDA error: invalid device function when compiling and running for amd gfx 1032

[nasawyer7]

Please include information about your system, the steps to reproduce the bug, and the version of llama.cpp that you are using. If possible, please provide a minimal code example that reproduces the bug. I have a 6700s amd gpu, 8gb vram. I got ooga to work on this computer, but I can't get llama.ccp to work. I compiled with make clean && make -j16 LLAMA_HIPBLAS=1 AMDGPU_TARGETS=gxf1032 And everything went fine. However, when I try to run, I do export HSA_OVERRIDE_GFX_VERSION=10.3.0 then HIP_VISIBLE_DEVICES=0 ./main -ngl 50 -m /home/lenovoubuntu/Downloads/text-generation-webui-main/models/dolphin-2.6-mistral-7b-dpo.Q4_K_M.gguf -p "Write a function in TypeScript that sums numbers". (I do HIP devices function since my devices has an igpu as well).

It returns ................................................................................................. llama_new_context_with_model: n_ctx = 512 llama_new_context_with_model: freq_base = 10000.0 llama_new_context_with_model: freq_scale = 1 llama_kv_cache_init: VRAM kv self = 64.00 MB llama_new_context_with_model: KV self size = 64.00 MiB, K (f16): 32.00 MiB, V (f16): 32.00 MiB llama_build_graph: non-view tensors processed: 676/676 llama_new_context_with_model: compute buffer total size = 76.19 MiB llama_new_context_with_model: VRAM scratch buffer: 73.00 MiB llama_new_context_with_model: total VRAM used: 4232.06 MiB (model: 4095.06 MiB, context: 137.00 MiB) CUDA error: invalid device function current device: 0, in function ggml_cuda_op_flatten at ggml-cuda.cu:7971 hipGetLastError() GGML_ASSERT: ggml-cuda.cu:226: !"CUDA error" Could not attach to process.

For more details, see /etc/sysctl.d/10-ptrace.conf ptrace: Operation not permitted. No stack. The program is not being run. Aborted (core dumped)

So, I ran it as as sudo, as it suggested using this command. sudo LD_LIBRARY_PATH=/opt/rocm/lib:$LD_LIBRARY_PATH HSA_OVERRIDE_GFX_VERSION=10.3.0 HIP_VISIBLE_DEVICES=0 ./main -ngl 50 -m /home/lenovoubuntu/Downloads/text-generation-webui-main/models/dolphin-2.6-mistral-7b-dpo.Q4_K_M.gguf -p "Write a function in TypeScript that sums numbers" I used all of those environment variables since ooga required them, and I was hoping they would fix things here too.

However, that just returns this after seemingly loading the model.

I get a similar error CUDA error: invalid device function current device: 0, in function ggml_cuda_op_flatten at ggml-cuda.cu:7971 on amd 780m (igpu) while trying to run any model. llama.cpp compiled with LLAMA_HIPBLAS=1 LLAMA_HIP_UMA=1 AMDGPU_TARGETS=gfx1100 and ran with HSA_OVERRIDE_GFX_VERSION=gfx1100 ROCm version 5.7.1

I also had similar error when running on my gfx90c device (which needs to be overridden to gfx900).

What solved the problem for me was also setting the environment variable HSA_OVERRIDE_GFX_VERSION when running make (together with the AMDGPU_TARGETS, although I'm not exactly sure if this value actually changes anything).

So for me, the make command would look like this:

HSA_OVERRIDE_GFX_VERSION=9.0.0 make -j16 LLAMA_HIPBLAS=1 LLAMA_HIP_UMA=1 AMDGPU_TARGETS=gfx900

I honestly didn't think that this would work at all, but it certainly did! For me, though, since my iGPU lacks INT8 operators, performance was worse than just using CPU, but it did run on the iGPU (checked with nvtop).

Hope that this works for you too!

My guess on why this hasn't been reported much

I would say that quite a few people have already ran export HSA_OVERRIDE_GFX_VERSION=xxx before, which would make this environment variable available to all programs running in the shell, making subsequent explicit declaration unnecessary.

Thank you! This hint finally allowed me to run all 33 layers of Mixtral Q5_K_M on iGPU. Since it's an APU with shared ram, it can't compete with dGPUs, but the speedup is close to 70% nonetheless.

Strangely, prompt processing is slower on GPU.
