I'm a programmer at a high-performance computing center. I'm not very familiar with R, but I have used MPI from C, C++, and Python. I have to run an R code provided by a guy who knows R, but not MPI. So, this fellow used the R snow library to parallelize his R code (theoretically, I'm not actually sure what he did.) I need to get this code running on our machines.
However, Rmpi and snow seem to require mpi spawn, which our computing center doesn't support. I even tried building Rmpi with MPICH1 instead of 2, because Rmpi has that option, but it still tries to use spawn. I can launch plenty of processes, but I have to launch them all at once at the beginning. Is there any way to convince Rmpi to just use those processes rather than trying to spawn its own? I haven't found any documentation on this issue, although I would've thought it would be quite common.
