R help - Aug 2006 - rpvm/snow packages on a cluster with dual-processor machines

Hi,

does anybody know how to use the dual processors in the machines of a cluster? I
am using R with rpvm and snow packages. I usually start pvm daemon and add host
machines first, and then run R to start my computing work. But I find that only
one processor in each machine is used in this way and the other one always stays
idle. Is there any simple way to tell pvm to use the two processors at the same
time? In other words, I would like to see two copies of R running on each
machine's two processors when using pvm. Any hints/help are greatly
appreciated.

Paul.

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.
