Hey Pavan, I sparked a discussion on the github repo of Open MPI: https://github.com/open-mpi/ompi/issues/1511 But I assume that a docker-native execution model would also do for MPICH.

Hey there,

I tinkered around with a ssh-less openmpi and I was wondering if it could be implemented in a nicer way. http://qnib.org/2016/03/31/dssh/

I just used -mca plm_rsh_agent /opt/qnib/src/dssh with a rather simple script to use docker exec:

#!/bin/bash

REMOTE_HOST=$1 shift set -x docker -H unix:///var/run/docker.sock exec -i -u ${USER} ${REMOTE_HOST} $@

Cheers Christian
