I usually just spew ssh tasks across whatever computing nodes I can
get my hands on.  It's less organized than something like mapreduce,
but I tend to run one-off tasks that I have to keep an eye on anyway.
I've done stuff like that across up to 100 or so machines and I think
it wouldn't be really worse if the number were a few times higher.  I
don't think it would scale to really large (10,000's of nodes) clusters.
