Parallel exectution problem #164

I have a 32-core machine and aim to run two separate blocks simultaneously, each utilizing 16 cores. However, after launching the jobs, I noticed an issue: both jobs are using the same 16 cores, leaving the other 16 cores idle. Manually running calphy_kernel -i input.yaml -k 0 and calphy_kernel -i input.yaml -k 1 results in the same problem. Are there any specific settings required to address this issue?

This issue also exist in openmp, if I set one core, and use multiple openmp threads, all threads will run on the first CPU core
