[Beowulf] cluster softwares supporting parallel CFD computing

We, at LFC, have some specific requests, and our cluster is not large (much
less powerfull than yours, a bunch of old PIII), so we use debian stable as
OS, MPICH 1.2.7 as Message Passing Libraries, Portland Group Compilers and
Intel Compilers, and netlib lapack and scalapack. We also use ACML with PGI
Compilers and MKL with Intel Compilers. Also we use FFTW 3.1.1.

Some questions: is your application already parallel? What kind of
parallelism (SM, MP) does it
uses? Are you going to use any cluster management software? Which
services are you going to run on the server (NFS,
NIS, etc)?
We use the master node to perform computation because 1) We don't have more
computers and we can't afford loosing another computer, and 2) The only
burden on this server is the NFS, and it is not that heavy.

Hope it helps...
