== Overview ==
On this page, we provide timing results obtained from 1-month benchmark GEOS-Chem simualtions.

== 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 from several GEOS-Chem 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 <tt>TIMERS=y</tt> (GNU Make) or <tt>-DTIMERS=y</tt>.

=== Overall wall time ===

[[Image:GC_1mon_benchmark_timing.png]]

The above plot displays the "wall clock" time from recent [[GEOS-Chem_benchmarking#1-month_benchmark|1-month GEOS-Chem benchmarks]]. All results displayed are from simulations that ran on all 24 CPUs of the holyjacob*.rc.fas.harvard.edu nodes (Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50 GHz) on Harvard's Odyssey cluster.
