If your computation is simple enough to express in terms of lapply or other apply calls that you want to have run in parallel then you might try the 'snow' package on CRAN which can run on top of Rmpi. Some places to get more details on that:

I need to rewrite a software in R, that runs on a cluster.
I thought Rmpi will be good for me but I can't find any help other than the Rmpi-manual that actually only describe the functions in the Rmpi package.
Can someone point me to some usefull guide?
For example, I would like to run a for-statement on several processors (a subset of the statement on each processor) but I can't figure out how to do this!
Thanks
