Balwinder show that when CLUBB_v2 flags are reverted as in CLUBB_v1, then the global solutions are similar (within 1 W/m2 of SWCF). However, the new options available in CLUBB_v2 offer opportunities for improvements to global simulations during the tuning process. .
Two six year simulations (control and test) were run on ne30_ne30 grid using compset FC5AV1C-L on Anvil using Intel compiler. Years 2 to 5 are analyzed using E3SM diags package:
Test simulation: SMS.ne30_ne30.FC5AV1C-L.anvil_intel.clbv2_rbsd_1_ed716943a4c
Control Siulation: SMS.ne30_ne30.FC5AV1C-L.anvil_intel.def_mstr_b5aaa6b7d228_clbv2_rbsd_1
E3SM diagnostics are available at the following web pages:
The history files are at (HPSS NERSC): A:/home/b/bsingh/SMS.ne30_ne30.FC5AV1C-L.anvil_intel.clbv2_rbsd_1_ed716943a4c.tar and A:/home/b/bsingh/SMS.ne30_ne30.FC5AV1C-L.anvil_intel.def_mstr_b5aaa6b7d228_clbv2_rbsd_1.tar
These files are archived as "tar" using HTAR.
Climo files: Climo files are inside the tar archive at: <test case name>/run/climo_fv/2-6yr/. For example: "SMS.ne30_ne30.FC5AV1C-L.anvil_intel.clbv2_rbsd_1_ed716943a4c/run/climo_fv/2-6yr/"

Balwinder has found that there is little change in runtime on Cori when CLUBBv2 is used in place of CLUBBv1. This could be improved if performance optimizations to clubb_intr, not included here, were added laterTo measure performance of CLUBBV2, two 5 days simulations (grid:ne30_ne30, Compset: FC5AV1C-L) were run on Anvil using Intel compiler. Following are the timings:
Control | Test | |
SYPD | 5.86 | 5.89 |
Advance CLUBB core (Wall clock time) | 1.915503e+04 | 1.641459e+04 |
CLUBB interface (Wall clock time) | 2.915716e+04 | 2.658124e+04 |
Advance CLUBB core is about 14% faster in CLUBBV2. These results are from a single run so we might need to evaluate the performance with more rigor.
