Running this debugger requires remote X acces. For this, familiarize yourself to this article. (Remote display on Cluster nodes).
Another article would be running MPI applications on the NCIT cluster and Debugging simple applications using Totalview.
Quicksteps:
Debugging MPI applications with totalview is simmilar to running simple debug with Totalview. You must only add -tv to mpirun, or you cand run totalview directly and select a Parallel job execution. (see user manual).
[alexandru.herisanu@fep-53-3 mpi]$ cat debug.sh
#!/bin/bash
module load compilers/gcc-4.1.2
module load mpi/openmpi-1.3.2_gcc-4.1.2
module load debuggers/totalview-8.4.1-7
setenv DISPLAY fep-53-3.grid.pub.ro:1000.0
# You can ask mpirun to start TotalView
#mpirun -np $NSLOTS -tv ./mpi_scatter
# or you can run it yourself, but now you have $NSLOTS available.
#You can use your own public/private key authentication or
#Sun Grid Engine's rsh
