qdel not killing all processes started under Intel MPI

$

Hi, when we run using Intel MPI with Hydra process manager (in a script submitted with qsub-- this is with OGS/GE 2011.11p1 on ROCKS 6.1 on a small blade cluster), qdel does not fully kill the job except when the the jobscript runs on the frontend. I have to kill the processes started by mpirun manually if the jobscript runs on a compute node. This is not a problem with OpenMPI.

Any ideas or suggestions on how to proceed with troubleshooting this would be much appreciated.

Thanks,

Noah
