We recently have created an MPI cluster of 4 Linux servers running
MPICH2 v1.2.1. I have tested MPI and it is working. I have been using
the parallel package in my scripts up to now. But, I would like to
switch to something that will allow me to run my R scripts on the new
I have managed to install Rmpi and I have been studying it.
However, I am wondering if Rmpi is the right way to go. Rmpi seems
to assume OpenMPI, but I don't know if that matters. I've never
used OpenMPI so I don't know if it is really that different: it
is still MPI so it can't be that different, right? I've been looking
at other packages too like snow et al.
It's a lot to digest and I am having dyspepsia ;o) Anyways, any
advice, tips, etc. for an MPI newbie who uses R are very welcome.
