Bug: CUDA error: CUBLAS_STATUS_NOT_INITIALIZED

[morgen52]

What happened?

Hi there.

My llama-server can work well with the following command:

/llama.cpp-b3985/build_gpu/bin/llama-server -m ../artifact/models/Mistral-7B-Instruct-v0.3.Q4_1.gguf -ngl 31 --threads 16 --batch-size 32 --ubatch-size 8

However, when I keep only the ngl parameter, my server crashes with confusing error message:

./llama.cpp-b3985/build_gpu/bin/llama-server -m ../artifact/models/Mistral-7B-Instruct-v0.3.Q4_1.gguf -ngl 31

I got an CUDA error: CUBLAS_STATUS_NOT_INITIALIZED:

Maybe it is a resource issue? I am not sure. Because when I try to set the --ngl to 32, the server crashes with a clearer error message, "cudaMalloc failed: out of memory"

What operating system are you seeing the problem on?

Linux

[morgen52]

common was recently changed a lot probably something to do with that

I think you are right.
When I start the server with:

 ./llama.cpp-b3985/build_gpu/bin/llama-server -m ../artifact/models/Mistral-7B-Instruct-v0.3.Q4_1.gguf -ngl 31 -c 8192

It can work properly.

And when I add the --no-warmup config:

./llama.cpp-b3985/build_gpu/bin/llama-server -m ../artifact/models/Mistral-7B-Instruct-v0.3.Q4_1.gguf -ngl 31 --no-warmup

It tells me that --no-warmup is not a valid argument
error: invalid argument: --no-warmup

So I think this hint should be updated.

[morgen52]

May I ask how context size affects GPU memory allocation?
My understanding is that context size is just a sliding window for context length. Is memory pre-allocated based on context size?
