Hello everybody; I've been setting up slurm into a 4 node cluster with 8 cores per node. One of my users is trying to launch some openmpi application with:
salloc -N2 mpirun myapp He claims that the application is running one instance for each node (using 8 cores each) instead of running only one instance that uses 16 cores I'm no expert on openmpi but maybe I forgot to add some config into slurm.conf MPI related stuff on slurm.conf: MpiDefault=none MpiParams=ports=12000-12200 And yes, I'm quite new with slurm, read a bunch of documentation but right now I'm kind lost with this issue. Cheers. -- Diego Lendoiro Inestable GNU/Linux Users Group Member | http://www.inestable.org In the beginning was the command line
