Installing Rmpi on NERSC's carver

The directory that contains MPI libraries is OMPI_DIR=/usr/common/usg/openmpi/1.4.5/intel; hence, we can adapt the code on this page (http://internet2.binghamton.edu/teragrid/readdoc.cgi?fname=1_1_Rmpi-Steele-2010-11-16.txt).

Use the following code in R.

local({
    my.configure.args <- list(
        "Rmpi" =
        c("--with-Rmpi-include=$OMPI_DIR/include",
          "--with-Rmpi-libpath=$OMPI_DIR/lib",
          "--with-Rmpi-type=OPENMPI")
        );
    options("configure.args" = my.configure.args);
    options(repos=c(CRAN="http://cran.cnr.Berkeley.edu"));
})
