R devel - Mar 2005 - How to use Rmpi?

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

If you haven't already, take a look at the snow package on CRAN.  It
provides an easier to use wrapper around either Rmpi or Rpvm.  The
included documentation has some examples that should get you going.

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:
