Dear FUNWAVE Users,

I do not have a problem running simulations with a 1 m grid size (1436*2245), it is not stable but it at least starts to Simulate. However, I received this error when I reduced the cell size to 0.5 m (2871*4489). 

BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
=   PID 82615 RUNNING AT funwave
=   EXIT CODE: 9
=   CLEANING UP REMAINING PROCESSES
=   YOU CAN IGNORE THE BELOW CLEANUP MESSAGES
===================================================================================
YOUR APPLICATION TERMINATED WITH THE EXIT STRING: Killed (signal 9)
This typically refers to a problem with your application.
Please see the FAQ page for debugging suggestions

Would you please give hints on what problems with the application raise this error?

Regards,

Saeed

Saeed,

This might need some procedural debugging, or be directed to your HPC admin/helpdesk. Generally, signal 9 means that the simulation exceeded its resources. Given that your grid just got four times bigger, you might run into space allocation issues for your global variables/arrays — you have nearly 13 million double variables (if you compiled in double precision) per 2D variable of field size.

On our HPC distributed systems, if this arose, we would submit hybrid jobs for more nodes, but assign fewer cores per node to the job (say half or quarter), this way the shared memory that sits on each node would shared across fewer cores. Hence, each core (or thread) would have more memory at its disposal to accommodate larger arrays.
