Real.exe corrupted without error information

[lacstorm]

Hi everyone. I'm using WRF3.5.1.
When I run real.exe by "mpirun -np 20 real.exe" for three nested domains.
The progress will stop after the first 2 domains are processed.
I got

===================================================================================
=   BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
=   RANK xx PID xxxx RUNNING at xxx pc
=   KILLED BY SIGNAL: 9 (Killed)
===================================================================================

The the rsl.out.0000 file did not show any error information and is given in the attachment.
The namelist is also given in the attachments since I always get a hint like "spam message, contains contatct."

However, when I use only one core by "./real.exe".
The real.exe could be ran successfully.
I'm very confused about this.
And actually I need a larger domain for

e_we = 361,  385,  421 
e_sn = 361, 373, 301.

And the real.exe will be killed even if I use one core with this larger domain.
When I type "free -m", the free memory is 61491, the total memory is 63911.
My disk place is not full and the enviroment WRFIO_NCD_LARGE_FILE_SUPPORT=1 and ulimit -s unlimited are set.

It's hard to say why this is happening, but the real program really does not need many processors to run because it's such a short/simple program. I almost always only use 1 processor for real. It's the wrf program that depends on multiple processors. If you are able to run real without problems with 1 processor, then perhaps you can move on to wrf.exe to see if you're able to run with the number of processors that you need.

Hi, kwerner, thanks for your reply.
Actually, I need a larger domain as

e_we = 361,  385,  421 
e_sn = 361, 373, 301.

And I can't run real.exe successfully even with only one core for this larger domain.

Hi,
Can you send your configure.wrf file (found in the WRF/ directory), along with all of the rsl* files when your real.exe run fails with multiple processors? You can package them altogether in a single *.TAR file. Thanks!
