How can I limit cpu cores to be used?

[amoeba04]

I'm using the server that multiple users are using.
When I run the code with deepspeed, it consumes every CPU core in high percentage and slows down other users' processes.

I want to limit the number of CPU cores when using deepspeed. How can I do this?

For example, I want something like:
CUDA_VISIBLE_DEVICES=0,1,2,3 VISIBLE_CPU_CORES=0-9 python main.py

or to set it in deepspeed configuration file like:
{
"zero_optimization": {
"stage": 3,
...
}
"num_workers": 10
}
