Basic question

[Gernot Plank]

Hi to all!
I have a maybe silly question to Beowulf experts.
We are planning to set up a small cluster of ~10 nodes during the next
year, and if the
results (in terms of speed) are ok, we think to enlarge it. Currently we
are using CRAYs
and MPI.

Now to my questions
    1) which linux-distribution is best for beowulf (redhat, suse, ...)
?
    2) what to you think is better PCs with one or more processors ?
    3) how's about connections between this PC's (Gbit/s,....) ?
    4) any additional hints ?

Hope anybody can help me and thanks in advance
   Gernot
