Hello, I am trying to run OpenMPI on a cluster where I am only allow to use RSH to spawn processes across compute nodes. I modified my mpirun command in this way:
mpirun -np 48 --hostfile ./hostfile --mca plm_rsh_agent "rsh" /central_storage/osu_barrier the file "hostfile" contain the machine where I am running mpirun plus another node. Libraries and osu_barrier are located in a central storage mounted by all nodes. The processes osu_barrier are spawn correctly across two nodes but no output is returned and the command seems stuck. Any idea what can I look at to try to solve this issue?
