Kumpute not offloading any gpu layers
Hello,
I was trying to use kompute, I manage to compile llamacpp kompute with the follow steps
git clone https://github.com/ggerganov/llama.cpp.git
cd llama.cpp/
#install kompute repo inside kompute folder
https://github.com/nomic-ai/kompute
mkdir -p build
cd build
cmake .. -DLLAMA_KOMPUTE=1
cmake --build . --config Release
then for run the model i did like the follow
./bin/main -m openhermes-2.5-neural-chat-v3-3-slerp.Q8_0.gguf -p "Hi you how are you" -ngl 90
and got the follow output
llm_load_tensors: offloading 0 repeating layers to GPU
llm_load_tensors: offloaded 0/33 layers to GPU
llm_load_tensors: CPU buffer size = 7338.64 MiB
what is the kompute doing for?
It theorically optimize performance for some gpus
it seems working fine on my set up( intel cpu + integrated gpu), it is said offloading to GPU with all layers however marginal perforamnce difference.
@userbox020 it looks Q8_0 quantization is not supported:
https://github.com/ggerganov/llama.cpp/blob/8f1be0d42f23016cb6819dbae01126699c4bd9bc/llama.cpp#L4488-L4502
You might notice with openhermes-2.5-neural-chat-v3-3-slerp.Q8_0.gguf:
llama_model_load: disabling Kompute due to unsupported model arch or quantization
Tested openhermes-2.5-neural-chat-v3-3-slerp.Q4_0.gguf with NVIDIA GeForce RTX 3050 and Kompute / Vulkan it managed to offload 16/33 layers to GPU. But performances are not there for this model, CPU is faster.
@phymbert thanks bro, going to check with lower quantz, do you know which one its the maximum it suporrt? in your code snippet looks like only q4 and f32 and f16 dont know what quant is it
Same issue here. Vulkan works ok-isch on my AMD Vega VII with about 20% GPU usage. Kompute does not work with models I tested like https://huggingface.co/TheBloke/WizardLM-1.0-Uncensored-Llama2-13B-GGUF

Sup bro they dont work because Kompute only support at the moment
model.ftype == LLAMA_FTYPE_ALL_F32 ||
model.ftype == LLAMA_FTYPE_MOSTLY_F16 ||
model.ftype == LLAMA_FTYPE_MOSTLY_Q4_0 ||
model.ftype == LLAMA_FTYPE_MOSTLY_Q4_1
and you trying a model Q4_K_M
Same issue here. Vulkan works ok-isch on my AMD Vega VII with about 20% GPU usage.

Click me
out of interest, how much performance gain you can have for these 20% GPU usage versus CPU?
Thats not make sense, kompute it's an optimized vulkan. Something must be wrong programmed or configurated. I managed to install llamacpp kompute but because it's still on development and only support 4 types of quantz I didnt do further tests. At the moment i'm working with llama vulkan
