[mvapich-discuss] Does MVAPICH have to be on each node to setup a ring?

[Matthew Koop]

Chris,

Yes, you will need to have MVAPICH2 installed on each node -- or available
on all nodes through NFS. You'll need to have the executable you're
running available on all nodes as well, so you'll need something like NFS
regardless.

Let us know if you have any other questions,

Matt
