I have a machine with 4 rtx2080ti and a core i9. I submit jobs to it through MPI PMI2 (from Relion).
If I use 5 MPI and 4 threads, then basically I'm using all 4 GPUs and 20 threads of my cpu. My question is, my current configuration allows submitting jobs to the same node, but with a different partition, but I'm not sure if I use #SBATCH --partition=cpu that the submitted jobs will only use the remaining 2 cores (4 threads) or is it going to share resources with my gpu job?! Thanks.
