Example simulated years per day for various configurations with E3SM v2.0
NOTE: v2 is in general faster than v1 because of the use of physgrid in EAM.
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.
