Can you please tell me whether all the computers in a cluster need to be installed with MPICH2 for running parallel programs or installing MPICH2 over a NFS shared folder is fine ?<div>e.g.</div><div>We have a 8 node cluster and /home is shared over NFS so running 'mpich2version' on all nodes gives </div>
