[R] rpvm/snow packages on a cluster with dual-processor machines

[Ramon Diaz-Uriarte]

Dear Paul,

I have no direct experience with rpvm, but doing it with rmpi is a piece of 
cake. I could provide you with some hints if you want. (I am tempted to ask 
why you are using PVM instead of MPI, but this might be the wrong question). 

Best,

R.
