Maybe ROCKS or whatever provides only one version. Anyway: you can download Open MPI, compile it to build into e.g. ~/local/openmpi-1.4.3, adjust your PATHs and you are done. Unless you build it with static libraries, it might in addition be necessary to adjust LD_LIBRARY_PATH at runtime. I use most often my own version on the clusters I have access to and disregard any installed one. -- Reuti > To state my question another way: Apparently each release of Linux and/or > Rocks comes with some version of OpenMPI bundled in.
