Hi Ankush, list
I am not sure I understand your machine setup,
but maybe it is a "server" machine and a "compute node"
somehow connected through a network
(or directly by an Ethernet cable), right?
If that is the case, yes you will be able to launch a program with
mpirun on the server machine, but it will only run in the compute node
if the work directory is mounted by the compute node.
This is the preferred way to run MPI programs.
If you want to run on a directory that is not exported to and mounted on
the compute node, you have to copy over all files (executable, input
files, etc) to that directory on the compute node.
This is not as comfortable a way to run MPI programs as the alternative
above.
Moreover, you need to tell mpiexec where you want the processes to run.
There are two basic ways to do this.
You can specify the nodes on the command line with the -host option,
or you can specify them in a file with the -hostfile option.
Do "mpiexec --help" to learn the details.
I hope this helps.

Thank you sir, thanks a lot.
The information you provided helped us a lot. Am currently going
through the OpenMPI FAQ and will contact you in case of any doubts.
