CMAQ run cctm error "invalid memory reference"

Hi,

I am trying to run cmac using a CPU node.

In the log of JobScript, the mcip, icon, and bcon processes were executed and a message was displayed indicating that they were completed normally.

Immediately after the run_cctm.csh file is executed, the following error occurs.

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

I also wrote “limit stacksize unlimited” in the .cshrc file of the home directory, wondering if it was a memory problem.

Please help if this is a computational resource problem or some other problem

There is most probably an un-checked ALLOCATE statement that is failing (production quality code should always check to see if failures happen with them, or with I/O statements, and in case of a failure should give a report sufficient to diagnose the problem, and then terminate gracefully.)

You may need limit memoryuse unlimited in addition to the limit stacksize unlimited.

The debug/traceback executable should give you more detail – exactly at which line in emis_defn_MOD_get_emis this is happening…
