CCSM/ESMF Evaluation Plans

The Community Climate System Model group at NCAR is approaching the adoption of ESMF through a series of evaluation plans. Three plans are anticipated.

The first plan was approved by the CCSM Scientific Steering Committee (SSC) in January, 2005. This plan focused on the component and redistribution functions of ESMF, and required that ESMF demonstrate less than 5% overhead relative to CCSM's existing infrastructure. ESMF successfully passed the evaluation in May, 2007 and the ESMF version was incorporated into the CCSM development repository.

The second plan was approved by the CCSM SSC in September, 2007. It focuses on evaluation of the regridding capabilities of ESMF, including petascale processor counts. A successful outcome will result in the ESMF version of ESMF being part of the next major release of CCSM, CCSM4. Work on this evaluation is ongoing.

The following slides show detailed plans used to implement ESMF in CCSM:
