On XCP_d: What does --mem_gb parameter control?

Software Support

Summary of what happened:

I’m running the XCP_d container on a HPC platform and one of the data gurus is helping me. We are reading the documentation on https://xcp-d.readthedocs.io/en/latest/usage.html. He would like clarification of one of the parameters:

--mem_gb, --mem-gb

Upper bound memory limit for xcp_d processes.

What does the mem_gb parameter control? Is this a mem-per-process, regardless of the number of threads, or is it mem-per-thread?

Hi @williamvdv,

I believe it is the total memory that can be allocated across all of XCP processes, and not a per-thread or per-process limit.

Best,
Steven
