    478478To activate MPI support on the CE and WNs, you need to define variable `ENABLE_MPI` to `true` in your site parameters (normally `pro_lcg2_config_site.tpl`). It is disabled by default.

     480A default set of RPMs for various flavours of MPI (MPICH, MPICH2, OPENMPI, LAM) will be installed. If you would like to install a custom version of a particular MPI implementation, you can do so by defining the following variables:
     481 * MPI_<flavour>_VERSION : Version of the package (e.g. MPI_MPICH_VERSION = "1.0.4")
     482 * MPI_<flavour>_RELEASE : Release number of the package (e.g. MPI_MPICH_RELEASE = "1.sl3.cl.1")
     483 * MPI_<flavour>_EXTRAVERSION : Patch number of the package (if needed e.g. MPI_MPICH_EXTRAVERSION="p1")
     484
     485By using variables, we ensure that the version published is consistent with the installed RPMs. N.B. this feature is available in QWG revisions >= 2493.
