Yes -- I happen to maintain GNU R, a number of R packages (eg r-cran-*) and more for Debian and am also part of Debian's Open MPI maintainer group. I also use Rmpi at work. Dr Yu and I sorted out all relevant issues a few weeks ago and the most current Rmpi (ie 0.5-5) works out of the box on Debian and Ubuntu, and is current in Debian. It should "just work" on any other recent Linux and Unix distro. If not please report back what configure reports and where it fails. [ As an aside, we do have a current bug in Debian unstable with Open MPI as we're trying to make transition between LAM, MPICH and Open MPI more bullet-proof. If you use just Open MPI you should already be fine. ] Greeting from Chicago, Dirk | | thanks, Randy | | | Begin forwarded message: | | > | > Subject: R npRmpi | > | > Been looking into the npRmpi problem | > | > I can get a segfault executing | >> mpi.spawn.Rslaves() | > | > The documentation .html files under npRmpi contains the following: | > | > "mpi.spawn.Rslaves to spawn R slaves on selected hosts.
