This is WRFV4.5.1 on aws Graviton3, using:

Code: 
Currently Loaded Modules:
  1) dmidecode/3.5    5) libevent/2.1.12   9) zlib/1.3
  2) numactl/2.0.16   6) pmix/5.0.1       10) hdf5/1.14.2

  4) gcc/13.2.0       8) openmpi/4.1.6

I build for dmpar GCC aarch64 (11) with basic nesting (1):

The build is successful:

I than do

Code: 
cd WRFV4.5.1/test/em_tropical_cyclone
srun -v --mpi=pmix -n 1 ./ideal.exe

which is also successful:

Code: 
$ tail -n3 rsl.out.0000

Finally I try to launch wrf.exe like this:

Code: 
srun -v --mpi=pmix -n 16 -c 4 -m block:block --cpu_bind=cores,verbose ./wrf.exe

and get this error:

I did not change any input files.

What am I doing wrong?

Actually, looking back at running ideal.exe, I see this:

wrf: SUCCESS COMPLETE IDEAL INIT

So I'm confused by the ERROR and at the same time SUCESS.
 
Hi,
That is interesting. It looks like the code prints the error because I suppose you're trying to use GHG input, but you aren't using the appropriate physics options with it. However, it seems problematic that it prints an error, but doesn't stop the model. I am running this by a colleague to see if the code needs to be updated. In the meantime, if you are not planning to use the GHG input, you can set ghg_input = 0 in the &physics namelist record. If you are wanting to use it, you'll need to change to one of the recommended radiation combinations.

Code: 
OK = CAM LW with CAM SW
OK = RRTM, RRTMG LW or SW, RRTMG_fast LW or SW may be mixed
 
yes, indeed, adding ghg_input=0 in the &physics record of namelist.input file helped.

Not sure why it was not there in the first place.

Now I get a segfault running wrf.exe with this input.
 
Okay, since the segfault is a new issue, please open a new thread and post it there. Please also include the necessary files to help us determine the issue (namelist.input and all rsl* files packaged into a single *.tar file). Thanks!
