Dear Daren,

First, please note that since this problem concerns a particular
package, you are supposed to contact the package maintainer (me)
directly. (See the R-FAQ, 9.2).

Anyway, I've never seen that error message before. But I think it
indicates a problem with your MPI setup, nothing related to R (and,
thus, neither ADaCGH nor Rmpi). A few things to try:

1. When ADaCGH fails, could you do a "traceback()" to see where
exactly is failing?

2. (in a newly started R session) please try something like the following:


And lets see how far the example gets.

3. How is MPI started? Is it LAM-MPI or OpenMPI?
