Cluster programming?

[sans-hubris]

Has anyone done any cluster programming? Some friend and I s plan on making a cluster and I've done some research. Is programming in Mpich difficult? Any caveats? Might it be better to use Mosix instead of having to write our programs to load balance themselves or would we still need to write the programs for the cluster with Mosix? Any thoughts?

mpich !? mosix? cluster programming?

I have a thought: huh? :)

never heard of Mpich or Mosix, but I haven't looked into this type of programmign at all.

MOSIX is worthless for non-forking applications, since it “load-balances” by migrating processes to the node most suitable.

I wouldn't say Mpich is hard to program in, but it's pretty... weird. :)
