Intel Dual core machines

[Randall Mackie]

Julian,

No, you do not need Rocks (and in fact it is a Linux-based system).
You mentioned the need to install MPI (which you do need for
PETSc), and I was just pointing out that there are clustering
software solutions that make a lot of getting the clusters set
up much simpler than doing it all yourself.

Rocks installs various flavors of MPICH, or MPI, or LAM....
