I assume network security etc. mean nothing to you, as the only service
you will be running there will openssh, the boxes will be put behind a
firewall and there is another person running the network in your
institution that knows everything that you don't need to know. You won't
be running X11 (the GUI) on them, so everything you need to know is how
to make them work as a cluster (assuming you want to make a cluster),
how to compile your libraries, install compilers and so on. Which
distro? I'd say: every major distro will be as good. Choose the one with
an easy installler, a modern version of gcc and a handful of useful
programs (vim/xemacs, gdb, basic libraries). You will be presumably
using ACML and other numerical libraries, which the distro most probably
won't have, so you will need to install them on your own anyway. My
recommendation is that you pick Mandrake, SuSE or Fedora.
