Dear R users, I am trying to use Rmpi in a Windows XP box to parallelize some simulations. Ultimately I would like to setup a small cluster of Win XP machines, but as a first step I only use one computer. Unfortunately Rgui crashes as soon as I call the function mpi.spawn.Rslaves() . Configuration: - R version 2.9.0 patched (2009-05-28 r48680) - Rmpi 0.5-5 windows binaries. - MPICH2-1.1 for Windows Any directions ? Thanks Jacques [[alternative HTML version deleted]]
