Subject: [OMPI users] Distribute app over open mpi
From: Arnaud Westenberg (arnaud_westenberg_at_[hidden])

Hi all,

Sorry for the newbie question, but I'm having a hard time finding the answer, as I'm not even familiar with the terminology...

I've setup a small cluster on Ubuntu (hardy) and everything is working great, including slurm etc. If I run the well known 'Pi' program I get the proper results returned from all the nodes.

However, I'm looking for a way such that I wouldn't need to install the application on each node, nor on the shared nfs. Currently I get the obvious error that the app is not found on the nodes on which it isn't installed.

The idea is that the master node would thus distribute the required (parts of the) program to the slave nodes so they can perform the assigned work.

Reason is that I want to run an FEA package on a much larger (redhat) cluster we currently use for CDF calculations. I really don't want to mess up the cluster as we bought it already configured and compiling new versions of the FEA package on it turns out to be a missing library nightmare.

Thanks for your help.
