(RESOLVED) WRF just hangs when I try to run

[yairsuari]

I want to thank everyone that answers
My problem is that when I try to run WRF it just stops. the last line in the wrf log is:
ThompMP: computing qr_acr_qg.
It seems like the error is somehow connected to mpi (multi processor) so I tried simply running ./wrf.exe - it did not help.

What I am doing is trying to work using the most standard configuration possible:
Compile and run is done using GNU tools according to the instructions in https://www2.mmm.ucar.edu/wrf/OnLineTutorial/compilation_tutorial.php. The only possible difference is that I am getting my GFS data from UCAR ds084.1 and not from operational data.

The only problem I see when preparing the data is after running metgrid
Note: The following floating-point exceptions are signalling: IEEE_OVERFLOW_FLAG IEEE_UNDERFLOW_FLAG IEEE_DENORMAL

I attach all the files I think might be relevant:
WRF and WPS namelists
logs for data preparation and real

Thanks again

Yair,
The problem is very likely that you aren't using enough processors for your domain size. You're only using a single processor, and your domains are all larger than 200 x 200. Take a look at this FAQ that discusses choosing a reasonable number of processors.

Thank you
I will test that

Thank you, it worked like a charm
