i've not written MPI programs before. I've written plenty of C and Java, however, and I think I can learn. I'm trying to decide whether to concentrate on OpenMPI or MPICH2 as I get started. In the Internet, I find plenty of people who are fiercely devoted to MPICH2, and I also find plenty of people who say OpenMPI is now the "preferred application".
I am afraid I will start a flame war between these two sides, but I do need some advice. My immediate goal is to write programs that can parallelize statistical analysis (mostly medium sized calculations that have to be run 1000s of times from various starting random number seeds). Many of the projects that we do will be in R, which has several packages that can be built for MPI framework (such as SNOW or such), but the installer must select which MPI library to build those packages against. What are the reasons to prefer one or the other? pj -- Paul E.
