Re: [R] Running R under Sun Grid Engine with OpenMPI tight integration
Did you make any progress in using R in the SGE / OpenMPI environment? I am asking, because I am struggling with the same problem. Using qsub does not give me an interactive session which I can use (wherefore I don't see a way of using RMPISNOW and getMPIcluster()) and the spawning (makeMPIcluster()) when R is running only yields slave processes on the node on which the master is running. I have the feeling, that I am missing something really basic - but what is it...

Re: [R] Running R under Sun Grid Engine with OpenMPI tight integration
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, actually there is no perfect way to use R one multiprocessors. There are two options: * using mpi: This means starting several R sessions and using MPI for the communication between the R sessions. Task distribution, fail over solutions, ... have to be implemented by your self. MPI was developed for multicomputer systems. So it is not very efficient to use it at a multiprocessor machine. But it works! * using multiThreads or openMP: There are packages from Luke Tierney using multi threading or openMP for basic R math functions. http://www.cs.uiowa.edu/~luke/R/experimental/ This are especially for multiprocessors designed math functions. You can achieve nice speedups. But unfortunately this is just working for the basic math functions. Have a look to the useR2008 conference and Dirks Tutorium. There you can find a lot of information!
