Hi Panayotis, Can you try specifying --procs, --num-threads, and --ppn-used at the same time? It looks like your machine defaulted to --ppn-used=112, which is not what you want, so you may need to overwrite it.
You can check your allocation details in /output-000x/SIMFACTORY/properties.ini. A useful strategy is to verify whether the allocation matches these relations: ppn-used = numthreads * nodeprocsprocs = numthreads * numprocs = nodes * ppn-used Below is my understanding (I personally use numsmt=1, so threads = cores in my case). Please correct me if I’m wrong on them: nodes = number of nodes procsrequested = total number of cores requested (may not all be used, but you still occupy them on the HPC) ppn = number of cores per node requested (may not all be used) numprocs = total number of MPI ranks actually used nodeprocs = number of MPI ranks per node actually used procs = total number of cores actually used numthreads = number of OpenMP threads per MPI rank actually used ppnused = number of cores per node actually used numsmt = number of threads per physical core Best, Wei
