Re: [R] parallel computing

Hi Moreno --

snow provides an easy interface to simple parallel types of calculations (e.g., lapply in parallel). I quickly wanted to have more direct control over how parallel computations were calculated, and have been using Rmpi. Though in principle snow and Rmpi are 'easy' to use, I found that they actually require a certain amount of understanding about R objects and evaluation, and the underlying communication library (MPI, or PVM).

Hope that helps,

Martin
