This page should describe Performance Assessment Tests performed for this stand alone feature and should provide links to all the result pages.

Performance Test 1 Standalone dycore
SL performance was measured at full scale on Edison and Cori-KNL. Results are documented in these slides. The first figure below is from those slides. The second figure shows SL performance when coupled to preqx, theta-l hydrostatic, and thetal-l nonydrostatic dycores/modes. In the first figure, there are 40 tracers; in the second, only 10.
Performance Test 2 preqx + sl?
Performance for coupled runs from /wiki/spaces/COM/pages/941096965 is evaluated from timers:
Default run: cam_run3(total homme time)=12613, dynamics in homme=2897, adv+remap in homme=8951
Run 20, almost optimal configuration: cam_run3(total homme time)=3654, dynamics in homme=1887, adv+remap in homme=1618
Overall, total saving in homme time is of more than factor of 3 for 1 degree run.
