Do I need to change inside my mpi > parallel code to run on infinipath environment ? Sounds like ClusterVisionOS? The module for the native Infinipath MPI is often called something like infinipath/mpi/compilername/2.1. By loading "base" and "ofed" you probably do not yet have loaded the MPI in your environment. Alternatively, you can also ask ClusterVision support to install an Infinipath-psm capable OpenMPI on your cluster, so you can continue using OpenMPI. Best regards, Daniël Mantione
