Provenance: Branch cameronsmith1/atm/Ozone-hole-Linoz-v2 from v0.3-212-gadbcc2b (simulations around Sept 5, 2015) 

Results: (link to results, data and plots)

 

Model cost for 2 degree FV ACMEv0.3 simulations on Titan with 560 PEs (x=pe-hrs/simulated_year):

MAM3                                                  mean(x) = 2333.83,   stddev(x) = 51.1981,   stderr(x) = 9.05064     ( 32 simulations of 4 months each)

MAM3 with Linoz                                 mean(x) = 2367.33,   stddev(x) = 40.3739,   stderr(x) = 12.1732     ( 11 simulations of 4 months each)     (+1.4% +/- 0.5% relative to MAM3)

MAM3 with Linoz and extra output      mean(x) = 2388.38,   stddev(x) = 43.6466,   stderr(x) = 13.16         ( 11 simulations of 4 months each)     (+2.3% +/- 0.6% relative to MAM3)

 

The extra cost of Linoz (1.4% +/- 0.5%) is in line with the expected cost of an extra tracer for FV.
