Well, I'd like to expose my Computing Independent Study (aka CIStheta)
class to MPI. I was wondering if it is easier to set up under SAGE.
I have run live Linux CD solutions for clustering for years now such
as ClusterKnoppix, BCCD and Quantian for openMosix and PVM. That was
years ago. More recently we've used parallelKnoppix, pelicanHPC and
ClusterByNight for MPI. I was thinking of setting up something more
permanent, however.
BTW, our adhoc cluster has 25 64bit dualcore AMD Athlons running 64bit
Ubuntu Desktop over a gigE switch. I did a little benchmarking
recently using pelicanHPC and ran 50 cores at about 24 GFLOPS. That's
not fast for a cluster these days, but fine for educational
demonstrations I think. Let's face it, IBM's Watson runs at 72 TFLOPS
which 3000 times faster, but my cluster doesn't have to play Jeopardy!

MPI is _the_ standard for passing data between different CPUs and
used to write parallel programs on clusters and supercomputers. Its
a rather low-level C library and you need to spend some time
learning it if you want to use it effectively.
Your random assembly of lab PCs is probably not terribly useful as
HPC cluster because the networking is likely to suck, unless the
workload is trivially parallel. Can your switch handle 25 gigabit-
ethernet connections at full speed?
