🐛 描述bug
我尝试使用nsys对vllm进行性能分析,并使用tp_size = 8运行混合推理。当我使用nsys GUI打开生成的req文件时,我发现除了排名为0的进程外,其他进程没有捕获cuda内核调用,也就是说没有cuda硬件行。这是nsys GUI的截图。
以下是nsys命令和Python脚本。
# nsys cmd
nsys profile -t cuda,nvtx --sample=none --cpuctxsw=none -o org_tp python3 offline_inference.py
# sample code for this problem, offline_inference.py
from vllm import LLM, SamplingParams
prompt_token_ids = [
[100 for i in range(8 * 1024)], # 8k
[100 for i in range(8 * 1024)], # 8k
[100 for i in range(8 * 1024)], # 8k
[100 for i in range(8 * 1024)], # 8k
[100 for i in range(32 * 1024)] # 32k
]
# Create a sampling params object.
sampling_params = SamplingParams(temperature=0.8, top_p=0.95, max_tokens=2)
# Create an LLM.
llm = LLM(model="mistralai/Mixtral-8X7B-Instruct-v0.1",
tensor_parallel_size = 8,
disable_log_stats=False,
enforce_eager=True)
# Generate texts from the prompts. The output is a list of RequestOutput objects
outputs = llm.generate(prompt_token_ids=prompt_token_ids, sampling_params=sampling_params)

我也尝试像这样配置每个工人:如何让ray支持Nsight System Profiler。但是没有效果,仍然没有cuda hw行

这是一个射线问题,刚刚已经解决。详细的解决方案在ray-project/ray#42139(评论)中。
