[Darshan-users] Darshan trace file not created for WRF

[Wadud Miah]

Hi,

I am trying to profile the I/O of WRF and have the following settings:

export DARSHAN_LOGPATH=/home/miahw/WRF_WADUD_PRE-COMPILED
LD_PRELOAD=/home/miahw/openmpi-4.1-darshan-3.4.5/lib/libdarshan.so mpirun -n $SLURM_NTASKS /apps/ku/gcc-9_4/openmpi-4_1/wrf/4.0/WRF/run/wrf.exe

However, no trace file gets created and the job stdout and stderr does not contain any Darshan warning/error messages. Can anyone suggest a way to increase debug level to investigate this further?

Regards,
