15 Apr 2020 NERSC Directory Change Notice

Due to project's name change at NERSC from 'ACME' to 'E3SM' and NERSC’s file system update, the directory '~~/project/projectdirs/acme/~~' is now '/cfs/cdirs/e3sm'

This page should describe Performance Assessment Tests performed for this stand alone feature and should provide links to all the result pages.

Summary

Two 1-year long simulations were performed with ALMv0 hydrology and VSFM. The tests were performed on Edison with same git hash and processor layout.
Results show that
- Simulation with VSFM is 2X expensive as compared to one with ALMv0 hydrology.
- The increase in computation cost is not only limited to LND run time, but CPL run time increases too.
