uhm, aside from NFS being SLOW and not scaling well?

For a small cluster, yes, it will work, but I wouldn't want to go above 50 nodes
without something with a little more oomph, or at least a couple dedicated IO nodes.

And if I were depending on the PGI compilers and core math libraries like Atlas,
FFTW and ACML, I wouldn't think twice about adding their runtime libraries to my
core image for the compute nodes.

Just my CAD 0.026
