Sadly, I have no Beowulf at home, that would not contribute to domestic bliss.
Work is another story.
There are several members or our group lurking on this list.
Maybe Vern would what to help with a Cluster presentation? What do you say
Our first one was a 24 node MPI based system consisting of 233MHz Pent. with
256MB ram that were about to be surplused. Boy did that system surprise the
powers that be. "You made this out of what?"
But, its gone now.
The second one is an 18 node 500MHz Celeron system with 1GB of memory /node.
The third one is an 40 node system, recently expanded to 67 nodes (I think).
These nodes have between 750 MB and 1 GB of memory per node. The CPUs are 750
MHz Athlons. It has just been expanded so, I'm not too sure of the exact
I'm currently building 9 more nodes of dual-Athlon MPs 2100+ with 3GB per
node. They will probably join the third system in some way.
What do we do with all this power? And heat? We simulate the absorbtion of
electromagnetic waves (radio and radar frequencies) in a 1mm resolution model
of the human (he's got over 365 million voxels).
We are using LAM-MPI and Layey Fortran 95 Express. And not much else. Since
these are not really shared resources.
Since the output data files are around 1.5 GB, I'm always looking for data
It is nice to know there are other Beowulf hackers out there.

They that can give up essential liberty
to obtain a little temporary safety
deserve neither liberty nor safety.
