unipost for parallel netcdf

Post-processing

Dear colleagues,
I use wrf-nmm v4.3 on the cluster, it produces wrf_output files in parallel netcdf format. I also have UPP v3.1.1 for the model outputs postprocessing. The problem is in the very low speed of execution of unipost.exe file (2.5-3 times slower than with ordinary netcdf)!
Can anyone help me to speed up this process?

The parallel netcdf capability has only been implemented for FV3 model cores in the UPP, so unfortunately other models (e.g. wrf-nmm) will not benefit from increased execution speeds of pnetcdf format.

Could you help me with the UPP post process the WRF-NMM output data? Could you share your run_unipost script and/wrf_cntl.parm file please?

I used the sample script modified to my paths and the sample wrf_cntl.parm (no modification). But it gave me segmentation fault in the "unipost_d01.00.out". I think I am missing something here. I can attach the error files if needed.
