Technical issues

Parallelization issues

High-Performance GEOS-Chem (GCHP)

Please see the GCHP user manual at gchp.readthedocs.io</tt?for more information.

Where can I get restart files for GEOS-Chem?

For instructions on how to obtain a set of sample restart files that you can use to spin up your own simulations, please see the Restart Files section of our GEOS-Chem basics wiki page.

Running GEOS-Chem

Please see our Running GEOS-Chem wiki page.

How long does GEOS-Chem take to run?

It depends on your particular computing environment. We have posted several timing results from GEOS-Chem 7-day time test simulations.

GEOS-Chem seems to be running too slowly. What can I do?

You should be aware of several compile-time options that will slow down GEOS-Chem. Use these options only for debugging, but not in your production runs.

If you are archiving many diagnostic quantities are a high temporal resolution (e.g. every hour), then this will increase the run time of your simulation. You can try saving out less diagnostic quantities, or archiving at a lower temporal resolution (e.g. every day).

GEOS-Chem errors

Please also see our Guide to GEOS-Chem error messages and Debugging GEOS-Chem pages.

GEOS-Chem died with an error. What can I do?

Please see Understanding the different categories of errors section of our Guide to GEOS-Chem error messages.
