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.

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:

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