Multi-core to run wrf.exe

Hi,

I am using WRF-LES to conduct simulation experiments at a 30-meter resolution. The compilation was successful since I can run both ideal.exe and wrf.exe with the default namelist.input. However, when I start using double nesting, wrf.exe throws an error, and I have uploaded the error log. Later, I discovered that when I use parallel computing, for example, mpirun -np 6 ./wrf.exe or mpirun -np 10 ./wrf.exe, it works successfully. I am puzzled as to why this happens. While I have access to more cores, if a user doesn’t have additional cores, does this mean they won’t be able to perform multi-nesting or large-domain simulations? namelist.input is also attached.

Any help would be greatly appreciated.
