Re: [OMPI users] Using open-mpi app on a normal network

You can do it, it might or might not make sense, depending on your application. Load imbalance in regular MPI applications kills performance. Therefore if your cluster is very heterogeneous, you might prefer some different programming paradigm that take care of this by nature (let say RPC).
