Overview

On this page we provide information about the 7-day timing tests that were done to evaluate GEOS-Chem simulations.

7-day time tests

The GEOS-Chem Support Team has created a timing test package that you can use to determine the performance of GEOS-Chem on your system. The time test runs the GEOS-Chem code for 7 model days with the "standard" chemistry mechanism. Our experience has shown that a 7-day simulation will give a more accurate timing result than a 1-day simulation. This is because much of the file I/O (i.e. HEMCO reading annual or monthly-mean emissions fields) occurs on the first day of a run.

We have run 7-day time tests for both v10-01, v11-01, and v11-02 aka 12.0.0. To view the results of the tests, please visit the following links:
