CMAQ running error

I worked before but it is not working now…
I do not know why?

Please review what modules are loaded, and what versions of openmpi you are using when running CMAQ.

Use the following commands:

Module avail will show you what modules are available on your server

module avail

Module list will show what modules are loaded

module list

If not module is loaded, then load the openmpi using

module load openmpi
Then use the command to verify that you are using the correct version of Open MPI.

mpirun -version

If you log out of your compute system, then you will need to reload the module in order to run CMAQ.
