Hi Matteo and others,

I have actually been trying out things from the notes.

Since the ++mpiexec option had worked in a previous cluster (but it isn't
working here), here's one thing I tried:

Create a mympiexec in home directory:
*#! /bin/bash
shift; shift; exec ibrun $**

And:
*charmrun +p12 namd2 ++verbose ++mpiexec ++remote-shell
/home1/nsengupta/mympiexec min01.inp > min01.out*

I now get:
*Charmrun> charmrun started...
Charmrun> mpiexec started
Charmrun> node programs all started
Charmrun> Couldn't find mpiexec program '/home1/nsengupta/mympiexec'!
Charmrun> error 0 attaching to node:
Timeout waiting for node-program to connect*

The error message is similar if I do not give an mpiexec file; I get *Charmrun>
Couldn't find mpiexec program 'mpiexec'!*

Can someone please help?

Thanks,
Neelanjana
