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

[Paul Y. Peng]

Hi Ramon,

please let me know how you achieve this with rmpi. I use PVM simply because I picked it up first and it worked well for me. If MPI is the only way to make use the two processors, I will find out whether it is available or works in our cluster. Thanks a lot for your response.

Regards,
Paul.
