Actually Redhat now has HPC pricing per node. There are other good
reasons to look elsewhere for HPC distributions though, specifically due
to their lack of good high performance/scalable per-node file system.
SuSE at least makes XFS and JFS available, and you can build/install a
system with these. Redhat prefers that you use ext3. Another issue for
the RHEL3 were the ancient kernels with many backports of advanced
functionality from modern kernels. Additionally adding modules for new
hardware support into their boot process is a minor nightmare...
