We've had success with the stock R rpms in centos and snow using the LAM/MPI envirionment. We use the "loose" lam integration for SGE described here: http://gridengine.sunsource.net/howto/lam-integration/lam-integration.html which takes care of starting and stopping the lam daemons on each node assigned by SGE. I assume a similar solution should be possible with PVM. The one issue we had problems with was staring R when using snow, particularly when using packages which invoke snow internally. Snow takes care of start the mpi parallelism for you so you shouldn't invode R via mpirun in the SGE job script. Simply using the lam_loose_rsh environment and putting the command "R CMD BATCH script.that.uses.snow" in the job file is sufficient. ~jpr On Thu, 27 Jul 2006, adolfo rafael martinez wrote: > Now, I just need to automate the startup of the PVM daemons on each > node, and make certain jobs can use the SGE qsub mechanism. > > If anyone has any tips, they would certainly be appreciated.
