I've found some C code that's ready to go with MPI. It's for doing matrix multiplication. So all that you'd have to do is find some nice big matrices to multiply! I guess you wouldn't even necessarily need to know the right answers either. Info link: http://www.hcsw.org/projects.html --> mmult.c D

Tim, Great, drop notes as opportunity provides. Peter P.S. my first reply bounced as being too large (apparently overlong posts requre moderator approval). So that's a nice reminder, also, to clean up some. Gmail's repackaging of quoted text makes it too easy to forget compounding replying. On 8/

actually I'm ambitious to build a small one myself, why I lurk here, but haven't committed to a specific plan yet. I really ought to get started with just a couple of heterogenous clunkers sitting around my place. Will be edifying. Peter On 8/16/07, Jack C <[EMAIL PROTECTED]> wrote: > > Haha ok,

Tim, I thought about this some. I don't have a cluster, but I can program in C; you have a cluster, but don't want to program too much. It's possible we can help each other. A toy application I thought of is finding numbers that can written as a sum of two cubes in two different ways (there's a fa

I think they found all the prime numbers already :))) To impress friends check out (parallel rendering): http://www.verrall.demon.co.uk/mpipov/ I believe [EMAIL PROTECTED] and [EMAIL PROTECTED] can use clusters (google for them) Then there is also parallel genetic algorithms. some coding need

Hi I recently built a small cluster/beowulf, out of old pentium II and III's, installed MPI, and generally felt happy. However, I dont have any applications to run on it. I have learnt some C++, but I dont really want to know how to paralyze code yet - I am more interested in the admin/building
