Hello! I have received some feedback from my cluster support and it seems that I am not being able to launch my multinode simulations because the ssh configuration is not enabled. Is there any other way to connect the nodes together? They also use infiniband to communicate data between nodes and it is the standard practice for sending data as well as gpfs mounted on all nodes so that data can be seen from any point in the cluster.

Has anybody faced this issue before or has any idea how to approach it? Any reply will be very much appreciated!
