Not really a beowulf question, but i'll bite. Some time ago, we had a
condor grid at my center with some pretty wild machines. The problem
was that no one had any use for it (they were obsessed with running
their projects on our beowulf despite the fact that they were mostly
single processor jobs). So i decided i'd run folding at home on 6 of the
nodes, just to put them to use somehow (I usually use one of our _true_
beowulfs for my work and anything serious).
Just set up f at h on each machine, giving each a different machine id
number, 1-6 should suffice. As for getting the data sets, you should
probably find some way of getting these nodes online... Do you have a
switch or some extra ethernet ports? Maybe use one of the machines as a
router? You could also whip up a script that would "pretend" to be each
instance of a machine id (1-6), receive the data, then place it in the
proper directory in each node.
Your script would run on a machine with internet access. It would start
a copy of f at h as a particular machine id (i think you can do this by
feeding it different config files). Once it has retreived the data,
kill the process, move the data to one of your nodes and repeat. As for
sending the data back... i'm at a loss.
Its been a while since I've run this, as it is more of a distributed
computing project than a beowulf-ready application, so i might be a
little off on this. However, you get the general idea.
