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:
library(Rmpi)
mpi.universe.size()
mpi.spawn.Rslaves()
mpi.remote.exec(rnorm(2))
And lets see how far the example gets.
3. How is MPI started? Is it LAM-MPI or OpenMPI?
Best,
R.

SegmentPlotWrite did produce alot of pngs and html. I tried again the same
example this morning (after a long night of installation), ADaCGH crashes at
mpiInit() showing the error:
