Error with wrf.exe when submitting sbatch job on AWS


New member
Good evening all,

The following errors comes out when i try to execute wrf.exe with slurm. However previously I have run successfully run the model with the same namelists and gfs data with the same procedures on AWS. I will greatly anticipate your advice. Thank you.

Good evening,

I have found the issue that caused this:

The slurm batch script needs an extra line of #!/bin/bash

Thank you so much and you may close this thread.
