I am trying to follow the instructions on this site for configuring an MPICH cluster on Ubuntu: https://help.ubuntu.com/community/MpichCluster.
I am new to this and have a very trivial question. In step two the instructions say "NFS allows us to create a folder on the master node and have it synced on all the other nodes. This folder can be used to store programs. To Install NFS just run this in the master node's terminal:"
I don't know how to switch into the master node's terminal so that I see a command prompt like "user@ub0" so I can install on that node.
Update: I tried
ssh user@ub0, but the terminal just stalls and doesn't do anything (it would usually say connection timed out, but I'm not even getting that...) do you know what would cause that?
