Configure MPI hostsfile to use multiple user identities

Does anyone know it is possible to specify the user which has to be used in an specific ssh connection with a given host or list of hosts in a MPI execution through mpirun? I need to use different users in different nodes.

  • I am running the Intel MPI implementation and it seems mpirun does not accept the -mca parameter – Genís Jul 30 '12 at 08:59

    `--mca` is Open MPI specific parameter. You should have stated in your question that you use Intel MPI or you should have used the `intel-mpi` tag. – Hristo Iliev Jul 30 '12 at 11:54

The solution I found is to configure the ssh client by means of defining hosts and the proper users in the ~/.ssh/config file, as explained in this blog .
