[OMPI users] Orted path with module manager on cluster

Hi all, I have built OpenMPI 1.10.2 with RoCE network support on our test cluster. On the cluster we use lmod to manage paths to different versions of softwares. The problem I have is that I receive the "orted: command not found" message given that the path to the orted binary is not exported to th
