Title: Openmp on multiple cores/nodes
Post by: youcan on August 18, 2020, 03:32:21 AM

Just out of curiosity, if I assign multiple cores/nodes to a slurm job which will use openmp, can openmp evenly distribute the threads among those cores/nodes for me? Thanks.

while MPI jobs can run on multiple nodes and single nodes avail to rn on either shared memory or distributed memory machines), openmp jobs are limited to running on a single node. they are shared memory applications.
