[R-sig-hpc] looking for an Rmpi example for a quad core desktop

The following link shows a very basic example running exactly 4 slave processes, one for each MCMC chain. There's an unnecessary large number of iterations just so that you can catch it with top (or qstat on batch systems).

Hi everyone!

Could anyone recommend a good example in Rmpi (or maybe snow) to use on a quad core desktop, please?

I would like to be able to run it and use the "top" function in another window to demonstrate how all of the cores are running.
