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.
