Subject: [OMPI users] single data/ mutilple processes
From: Jim Kress (jimkress_35_at_[hidden])

I need to use openMPI in a mode where the input and output data reside
on one node of my cluster while all the other nodes are just used for
computation and send data to/from the head node.

All I can find in the documentation are cases showing how to use openMPI
for cases where input and output data reside on all the nodes.

Will anyone please show me the command line I need to use to accomplish
my single data/ multiple node calculation?

Thanks.

Jim
