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.

We are also working to make multi-node GCHP simulations possible on the AWS cloud platform. This work is still in the research stage.

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:

Configuring your environment for GEOS-Chem Classic

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.

Configuring your environment for GCHP

GCHP requires some additional software libraries (e.g. ESMF, gFTL) that GEOS-Chem "Classic" does not. Please see Setting Up the GCHP Environment for detailed instructions on how to set up a GCHP simulation on your system.
