The above plot displays the "wall clock" time spent in each model component as observed in recent GEOS-Chem 1-month benchmark simulations. (Credit: Melissa Sulprizio). Timing results from both public and internal benchmarks have been included. This type of plot can be very helpful in determining if updates made to GEOS-Chem cause significant computational bottlenecks.
 
Timing information is obtained from the GEOS-Chem "Timers" output, which is printed to the log file.  Timers output is activated when compiling GEOS-Chem with <tt>TIMERS=y</tt> (GNU Make) or <tt>-DTIMERS=y</tt>.

Wall time spent in model components

The above plot displays the "wall clock" time spent in each model component as observed in the GEOS-Chem timers output from 1-month benchmark simulations. This type of plot can be very helpful in determining if updates made to GEOS-Chem cause significant computational bottlenecks. Timers output is activated by setting use_gcclassic_timers: true in geoschem_config.yml and is printed to the log file.
