The club has been looking for an excuse to build a cluster and has been trying to find
some hardware. I thought this Seti project would be a good place to start. I don't
know anything about Seti so I thought I'd offer the opportunity here. If Seti is the
limitation, then I'll let him know his original idea ( several Windoze boxes ) is the
best one.

A lot of common applications can see a performance boost on
distributed/clustered computer system _IF_ the given applications uses
specific math libraries heavely. The idea is that you install the
distributed/cluster versions of the math libraries then any app that uses
them could see a performance boost.
I think some of the common math libraries that have distributed/clustered
versions are BLAZ and LaPAC. (The spelling could be way off on those I just
remember the phonetic pronouciation.)

Beowulf works best with applications that are designed for parallel
computation. Programs designed to not share address and memory space among
it's various processes.
>From the seti site:
"Are there versions of SETI@home for parallel systems such as Beowulf or
multiprocessors?
No. You can parallelize SETI@home by running multiple instances of it,
either on a multiprocessor or on the nodes of a cluster. Just make sure
that each instance runs in a different directory. "
IMHO, seti would probably perform better on each workstation, individually.
Or to say it another way, there probably won't be any gain from putting seti
on a beowulf cluster. Your assocate there should have as many computers as
he can chunking away, individually. The faster the processor, the faster it
will complete a block. (I'm running it on one system, a thunderbird
1.333ghz. It takes about 8 hours for one block.)
Here's a little article discussing an intro to beowulf systems, and
home-brewed super computers.
