Thanks Ralph after giving full path of hello it runs.
But it run only on one rank
Hello World! from process 0 out of 1 on node56.beowulf.cluster

Just to check things out, I would do:

mpirun --display-allocation --display-map -np 4 ....

That should show you the allocation and where OMPI is putting the procs.

there also a error
>cat my-script.sh.e43
stty: standard input: Invalid argument

Not really sure here - must be an error in the script itself.

You need to include the path to "hello" unless it sits in your PATH environment!

mpirun was unable to launch the specified application as it could not find an executable:

Executable: hello
Node: node56.beowulf.cluster

while attempting to start process rank 0.
==================================

I could run the  binary directly on the node without any problem.
 mpiexec -n 4 hello
Hello World! from process 2 out of 4 on node56.beowulf.cluster
Hello World! from process 0 out of 4 on node56.beowulf.cluster
Hello World! from process 3 out of 4 on node56.beowulf.cluster
Hello World! from process 1 out of 4 on node56.beowulf.cluster

Could you please advise, if I missing anything here.


Regards
Govind
