[R] Viable Approach to Parallel R?

[Eric W Anderson]

Hi Dan,

I've had pretty good luck using Snow with with Rpvm.  It's definitely
not what you'd call "plug and play," but it does work.  I'm using it on
a single computer to just take advantage of multiple processors, and it
does a pretty good job of keeping them busy.  The main gotchas I've
found with Snow are in data dissemination:  You may have to
clusterCall(cl, "require(foo)") or clusterExport(cl,bar) more things
than you would have expected.

-Eric
