Oh, yeah... flames if you top post. Ok...

I want to ask what kind of experiencies do you has in the
implementation of a beowulf cluster (using Gentoo or Fedora in AMD64
architectures) for metheorological applications and wich one of the
distros do you recommend me.
it should not matter. distros are all about desktop decor,
which is irrelevant to cluster applications. you should use a distro
which your admins are comfortable with - the packaging
format, for instance. I personally find yum very good, and thus
prefer RH-like distros. I doubt that meteorological apps have any
special properties beyond the normal working kernel/filesystem/
compiler/scheduler/mpi stuff, which should be achievable in any distro.
We run WRF and MM5, NCARG, NCL and Gempak here. One cluster is SuSE
(came that way, didn't change it) and another is Rocks (an experiment).
Likely, when we reimage everything it will be Fedora. Fedora 7 (and
6, I think) have RPMs for netcdf and ncarg which saves a little bit of
the headache associated with their install... but only a little.
I suspect we'll go with Fedora or CentOS depending on a coin-toss or a
previous night's beer-laden decision, but we'll almost certainly use a
yum-based updater for convenience.
As Mark points out, distros are mostly for eye-candy. Our typical
install is stripped down, then we customize with packages (like WRF,
WPS, NCARG and Gempak) and parallelizable packages like NetCDF, which
isn't out in rpm, I don't think) manually.
We won't intentionally use AiX (which is on our IBM p575 Cluster1600)
intentionally. If I take over the care and feeding of that system, it's
likely to grow linux if we can get drivers for the Foundation switches.
