Good morning, I started using Gromacs only few months ago doing MD on
proteins in membranes.
I' m using GRomacs 3.3.1 in parallel but I have some problems. I'm
doing my simulations on a 70  nodes cluster using 4 nodes (16
processors). the system uses PBS torque and SCALIMPI libraries.
When I run my jobs, the jobs start with no problems, even if there is
the following error message :

When I want to delete a job, I use qdel; at this point the job
desappears from queue, but apparently the job is still running on the
processors. The output files are not updated and I have to enter the
nodes and force killing the processes with kill -9 .
This happens also if MD starts but crashes in a few seconds due for
example two overlapping atoms. The job desappears from queue but is
apparently running on nodes.
The error message is the following:

--- mpimon --- Aborting run after interrupt ---

What could be the origin of this problems?

Thank you very much

Fabio
