Example simulated years per day for various configurations with E3SM v2.0
v2 is in general faster then v1 because of the use of physgrid in the atmosphere.
Each entry in the table has: Number of nodes/machine, pecount designation (actual SYPD). Current and past machines are represented.
"def" means that its the default node count for the compset/resolution
Unless otherwise specified, tests were done with without I/O and the default compiler and MPI library and settings are available on latest master. Adding I/O will slow down the model.
Data was obtained from: comments in config_pesall.xml and PRs modifying it, pace.ornl.gov database, confluence pages.
