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.... Randy Julian wrote: > Thanks for the reply. > > Do I really need to use ROCKS if I'm just gonna use a single dual core > machine ?
