Sorry Saurabh; all of us are caught up in preparing for the Supercomputing trade show next week. We've been delayed in replying to list email. :-(
We actually take the opposite approach than MPICH: nothing is exported to remote processes by default except for internal Open MPI env variables. The -x option is provided as a way to selectively export env vars if you want them. We went this way because many run time systems already export environments for you to the remote processes, and sometimes they even selectively edit the environment (e.g., some env vars will have different values for different MPI processes). We didn't want Open MPI to override that behavior. ssh, of course, doesn't export things for you automatically. But there are some options in ssh to automatically forward environment variables, if you want to go that route. Hope that helps. > On Nov 13, 2015, at 2:56 PM, Saurabh T <saur...@hotmail.com> wrote: > > I'd appreciate a response, even a simple no if this is not possible.
