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: cloud.geos-chem.org.

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

If you are using your own computational cluster

Click on the following links to learn 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.
