Segmentation Fault with ECMWF's IFS and GFS dataset

[aimuni]

Hi, all

I hope this is the right place for this problem. I'm currently trying to run WRF with using IFS and GFS dataset (to correct for the soil levels of IFS dataset). I've managed to run WPS and real.exe successfully, producing three output files: wrfbdy, wrfinput_01 and wrfinput_02 for each domain. However I'm encountering a problem with running wrf.exe. Every time I run this part the run stops halfway and this error pop up:

starting wrf task 0 of 1
Segmentation fault (core dumped)

I've attached my namelist and my rsl files for convenience. I've tried to alter different variables in the namelist but to not avail. The same error of segmentation fault keeps appearing. For your information, I'm using GNU (gfortran/gcc) compilers for this run.


Appreciate the help I can get, thanks!

Hi,
The issue is very likely due to the fact that you're only using a single processor for this simulation, but your domains are large enough that it's going to take many more than that. See Choosing an Appropriate Number of Processors for details.
