If you are using the Amazon Web Services cloud platform

When you start a new AWS EC2 cloud instance, you will typically load an AMI (Amazon Machine Image) with a pre-defined computational environment. The AMI will contain an operating system, compiler version, and required software libraries for GEOS-Chem. The relevant Unix environment variables will also be defined properly. For more information, please see our cloud-computing tutorial:

You may now skip ahead to our chapter on Downloading GEOS-Chem source code.

If you are using your own computational cluster

If you wish to run GEOS-Chem on the computational cluster at your institution, then follow these steps to make sure that your login environment is properly configured for GEOS-Chem:

Click on the following links to learn more about how to prepare your computational environment to run GEOS-Chem "Classic".

  1. Specify the compiler
  2. Specify software libraries
  3. Specify parallelization settings

We also provide a a sample initialization script containing the various settings described in the links above.
