this sounds more and more external to pv. For example if you compiled
your program with one version of mpi but tried to run it with another,
you'd very likely see exactly what you are seeing here. A few of things
you could look at to boost your confidence: "module list", "which
mpirun", "echo $LD_LIBRARY_PATH", "ldd pvbatch" all of which will let
you confirm that your environment is using the mpi and library versions
that you expect, and that PV itself can find it's dependencies.
Sometimes sys admins in attempt to make things easy load modules for
you. So when you are put into a new shell you environment is changed.
And of course the default modules will change as packages are updated.
This could lead to unexepected weird problems over time. So, when
running something like paraview that has a lot of dependencies, it can
be helpful if you "freeze" your PATH and LD_LIBRARY_PATH. copy these
into a bash script (or module file) which you source when using
paraview, and then pass these into your qsub script with "-v" option.

assuming that you've already examined all the output, and there's
no other info, you could do a couple of things: put some print
statements in your python script to see how far it makes it. Also
you could use MPT specific environment variables that tell mpt to
print a stack trace, see man mpi. A debug build may be helpful for
this.
before all this debugging effort you may want try a very simple
script to gain confidence that things are indeed working correctly
with your build. I'll send a simple test script that might be of
use for that.
It doesn't even get past the first line i.e the module import line.
I'm unable to get it to force a core dump as "ulimit -c unlimited" is
not working. I've asked the system administrator about the issue.
But in the meanwhile can I force a debug compilation? How can I do
that? Just add "-g" to CMAKE_C_FLAGS and CMAKE_CXX_FLAGS?
