VM cluster for MPI runs
From the previous class, you should already have two VMs
with a cluster master host, clmaster, and a compute node, clnode01:
In the exercises today, we'll do the following steps:
Set passwordless SSH public/private key authentication between clmaster and clnode01
Copy the MPI installation, /usr/local/openmpi, from clmaster to clnode01.
Add another computational node, clnode02, by cloning clnode01.
Run MPI job across three VMs: clmaster, clnode01, clnode02.
