[Wrf-users] WRFV3.1.1 issue

[Irene Gallai]

Hi Elliot,

I think you could have setted the namelist entries nproc_x and nproc_y 
in the &domains
section with the wrong values; correct values should give you as their 
product (nproc_x * nproc_y ) the number of processors used.
In alternative you could use the defaukt values  setting them both to -1.
So if you want run tour code with 8 processors you should set nproc_x or 
nproc_y  respectively to 1 and 8 or 2 and 4, just to make an example.

If the entries in your namelist are not wrong maybe you make some 
mistake when launching the executable? How do you specify the number
of processors?
 

I hope this could aid you

Irene
