Overview

This manual will walk you through setting up and running GEOS-Chem simulations in "Classic" mode (using OpenMP parallelization across several cores of a single computational node).

If you interested in using GEOS-Chem's high-performance mode (GCHP) to parallelize across hundreds or thousands of computational cores, please see: https://gchp.readthedocs.io.

System requirements for GEOS-Chem Classic

Before obtaining the GEOS-Chem source code, you should consider if your computational system meets the minimum system requirements. Please see the following chapters for more information:

1. GEOS-Chem required hardware
2. GEOS-Chem required software
3. GEOS-Chem required disk space
