Did you know that a single license of AERMOD View allows you to perform multiple concurrent AERMOD runs on multiple computers? It’s true! When you install AERMOD View, several additional utility programs are included, and one of these – Batcher – allows modelers to set up a queue of model runs. Batcher can be executed from any computer where AERMOD View is installed even if the full application is not licensed.
Batcher can conduct AERMOD, ISCST3, or ISC-PRIME runs. Users populate an executable list via the Browse icon 
next to the executable drop-down list. All executables available to the main interface can be added to Batcher.
The Batcher interface.
The standard EPA executables can be run on any copy of Batcher. If a user wants to model using Lakes’ parallelized AERMOD MPI executable, a secondary web license is included with every copy of AERMOD View to allow for independent execution of AERMOD MPI via Batcher on a separate computer from wherever the main license is installed.
Activating the AERMOD MPI license only requires a few steps:
Step 1: Download and install AERMOD View and MPICH2 on the computer where you want to run AERMOD MPI.
Step 2: Open Batcher and select the menu option File | License Admin – AERMOD MPI.
Step 3: The Web License Administration window is displayed. Specify the Serial # and Activation Key for AERMOD MPI you received by email and press the Activate button.
Step 4: A message is displayed stating that the license was successfully activated. Press OK and close the License Admin window.
Note: You do not have to activate the AERMOD MPI license in the computer where you already have the full AERMOD View activated. The AERMOD MPI Web License is a second activation for another computer to run the AERMOD MPI executable via Batcher.
Once activated, you can add AERMOD MPI executables to your executable list, select the desired version, and identify how many processors you want to use (maximum of 8).
