But I must confess, I am a bit confused about the significance of the .Rprofile provided with Rmpi. I'm quite sure this is because I am a total noob concerning HPC but maybe you can help me understand the issue. After Stephen's response I changed my script to: require(Rmpi) print(mpi.remote.exec(rnorm(5))) mpi.close.Rslaves() mpi.quit() and called it with /programs/openmpi-1.3.3/bin/orterun -host node02,node03 -n 4 Rscript mpiTest_03.R
You are not necessarily getting the Rmpi .Rprofile. To use it, you need to copy it to your startup directory, or link from there. Or you need to set an environment variable or use an R command line option. On Debian Lenny, r-cran-rmpi (thanks to Dirk for the packaging) has the file at /usr/lib/R/site-library/Rmpi/Rprofile As others have said, you don't necessarily want to use that profile; it depends on how you want to use Rmpi.
