[Beowulf] [newbie question] Does HPL have to be installed on every node in the cluster?

Hi Perry,

When you run an MPI program on a cluster, the executable usually needs 
to be visible in the same location on all the nodes. This might mean
installing the application on each node, but for many clusters it just
means putting the executable on a network filesystem which is visible to 
all the nodes. 

So for example if /home is an NFS filesystem mounted on all the nodes, 
you should be able to run a binary under /home across the nodes with MPI. 
I don't have any experience with ROCKS so I don't know if it sets up an NFS
filesystem by default.

If you don't want a shared filesystem, you can install the app separately
on each node instead.

Adam
