What happened?

I'm using the openai library to interact with llama-server docker image on an A6000:

docker run -p 8080:8080 --name llama-server -v ~/gguf_models:/models --gpus all ghcr.io/ggerganov/llama.cpp:server-cuda -m models/Meta-Llama-3.1-70B-Instruct-Q4_K_L.gguf -c 65536 -fa --host 0.0.0.0 --port 8080 --n-gpu-layers 99 -ctk q4_0 -ctv q4_0 -t 4

The first request I send takes about 80 seconds, during which at first a single CPU core gets 100% load for maybe ~55s (with GPU usage at 0%) and only then the GPU kicks in. The second time I execute the exact same call, it takes ~26s to respond and starts with both CPU (one core 100%) and GPU (~87%) working a the same time.

The API call itself is:

import openai  # openai-1.45.0

api_url = 'http://x.x.x.x:8080'

client = openai.OpenAI(
    base_url=f"{api_url}/v1",
    api_key = "unused"
)

messages = [
    {"role": "system", "content": "You are a helpful assistant. Your top priority is answering user questions truthfully, based solely on the information provided."},
    {"role": "user", "content": prompt} # prompt is around 450 words
]

completion = client.chat.completions.create(
    model=None,
    temperature=0.0,
    messages=messages
).choices[0].message

Name and Version

$./llama-server --version
version: 0 (unknown)
built with cc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0 for x86_64-linux-gnu

^^^ not very helpful but I have just pulled a fresh docker image today i.e. 15/09/2024:
docker pull ghcr.io/ggerganov/llama.cpp:server-cuda

What operating system are you seeing the problem on?

Linux

Has this started happening recently? Does it happen without docker?

I can't reproduce on my CUDA workstation.

Happens both with and without docker. I wasn't using llama-server before so can't say if it's new or not.

Hm, does adding --no-mmap help?

Doesn't help unfortunately.

@ggerganov I was able to reproduce the problem on HF endpoints with A10G GPU (I didn't notice this issue before).

The first llama_decode takes ~20s, you can see the delay between decoding batch and next token in the log below.

Here is the log with --verbose. Sorry I don't have a build with LLAMA_DEBUG=1, so please test it if you can.

I just had it happen on an A10 machine as well using llama-bench. 1 CPU core was at 100% and the GPU was idle. Waited for 2-3 minutes and killed the process. Next runs were normal and didn't happen again.
