[RegCNET] regcm in cray

[priyanka banerjee]

Hello,

I am trying to install RegCM4.5 in our Cray XC40. There is no issue with
the preprocessing steps. However, when I am submitting a run  the model
stops within a minute and I get the following error message:

[NID 01409] 2017-11-16 14:52:44 Apid 77755: initiated application
termination
[NID 01409] 2017-11-16 14:52:44 Apid 77755: OOM killer terminated this
process.

It means that the code has exhausted the memory available on the node (OOM
stands for
"out of memory").

Some details about the model set-up are given below:

I have loaded the modules PrgEnv-intel, cray-netcdf, cray-hdf5,cary-mpich
and pbs.
My domain information : iy     = 176,
                                     jx     = 240,
                                     kz     = 18,
                                     ds=   30.0,
                                     dt =      45.,

The script that I am using to submit job is:

#!/bin/csh
#PBS -N test
#PBS -l select=5:ncpus=24
#PBS -l walltime=02:00:00
#PBS -l place=scatter
#PBS -l accelerator_type="None"
#PBS -S /bin/csh -V
. /opt/modules/default/init/csh
cd  /to/the/run/folder
aprun -j 1 -n 120 -N 24 /regcm/build/folder/regcmMPI test.in > outfile

Any thoughts on how to overcome this issue?

Thanks a lot .............. Priyanka
