Using the mpirun_dbg.idb Startup File

The latest MPICH distribution should come with the Intel Debugger startup file mpirun_dbg.idb. If it does not, or if you are using an older distribution of MPICH, you can create the startup file by saving the following script as mpirun_dbg.idb in the directory in which mpirun resides:

#! /bin/sh
cmdLineArgs=""
p4pgfile=""
p4workdir=""
prognamemain=""
p4ssport=""
processedCmdLineArgs=""
#
# Extract -p4ssport info from the string passed in via -cmdlineargs.
#
function processCmdLineArgs()
{
    while [ 1 -le $# ] ; do
        arg=$1
        shift
        case $arg in
            -p4ssport)
               p4ssport="-p4ssport $1"
               shift
               ;;
            *)
               processedCmdLineArgs="$processedCmdLineArgs $arg"
               ;;
      esac
    done
}
while [ 1 -le $# ] ; do
  arg=$1
  shift
  case $arg in
     -cmdlineargs)
        cmdLineArgs="$1"
