Timing results from 1-month benchmarks

To access the entire history of GEOS-Chem benchmarks, please see our GEOS-Chem versions page.

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 recent public and internal 1-month benchmark simulations (Credit: Melissa Sulprizio). 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 TIMERS=y (GNU Make) or -DTIMERS=y and turning on timers in input.geos.
