Barnet,
This isn't the most straightforward solution, but as a workaround, create a
bash script and run that script through npRmpi? Something like:
!#/bin/bash
openmpi -np 15 -hostfile /path/to/hostfile $1

deeper, it turns out that there was a typo in the iptables file for the
nodes: they were accepting all traffic on eth1 instead of eth0. Only the master has an eth1 port.
When I checked the tables earlier, I didn't notice the discrepancy.
Thank you all so much!

Yes. I am able to log in remotely to all nodes from the
your using.
The machine file is a simple list of hostnames, as an example:
m43
taygeta

David,
I did try that after I sent the original mail, but the -np 4 flag doesn't fix
the problem, the program still hangs. I've also double checked the iptables for
the image and for the master node, and all ports are set to accept.
Cheers,

r, and each machine uses the same image (and thus the same paths). If there was a problem with
the path, it would not run.
Any insight would be appreciated.
Thank you,

Arun,
Before you call any MPI subroutines, you have to call MPI_Init(ierr) first.
Once you put that line in, it should work.
Cheers,
