CESM is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states. ACME's atmosphere component is the Community Atmosphere Model. The CAM model has flexible formulations for atmospheric dynamics and has recently transitioned to the spectral finite element method coupled to an extensive suite of sub-grid physical parameterizations in its standard configuration. It runs on unstructured quadrilateral grids. The land model, CLM, contains a suite of column process parameterizations running at each grid point with no communication between grid points. CLM represents surface and subsurface water, energy, carbon, and nitrogen dynamics, with a nested hierarchical sub-grid parameterization that allows glaciers, lakes, urban areas, agricultural fields, managed forest, and natural (unmanaged) vegetation types to share space on each grid-cell. Incident radiation is intercepted in a two-layer canopy, with vegetation, soil, snow aging, and black carbon impacts on albedo. Subsurface processes include vertically resolved biogeochemistry, options for carbon and nutrient cycle parameterization, and recently improved treatment of wetlands and permafrost dynamics. In the fully-coupled configuration, the sea-ice and ocean (MPAS-CICE and MPAS-O) component models run with a nominal grid spacing of 1/10° (approximately 15km at the equator and 5km in polar regions) and, for MPAS-O, 100 levels in the vertical. CAM grids have both uniform and variable resolution configurations. The uniform grid with an average grid point spacing at the equator of 1/4° contains 86,400 elements, each with 30 vertical levels. Doubling the resolution to an average grid spacing of 1/8° requires 345,600 elements. The variable resolution configuration allows a small region of 1/8° grid spacing transitioning to an average global resolution of 1°. The CLM is run on the same grid as CAM. The output of the ACME consists of monthly means of several hundred quantities, plus daily averages of a subset of these quantities and hourly output of some key variabl es. ACME requires Fortran90 and C compilers and the MPI library to run. We will be using time on Blues to perform regular testing of ACME. ACME contains a large set of system tests that perform runs of the full model to test various functions. The runs sizes range from a few nodes to a few dozen nodes. The output sizes are relatively small and we will have modest storage needs. In FY17 we will continue regular testing with the gnu compiler and the large "acme_integration" test suite. In Current: undetermined amount Justification: Requested: 80000 A specific reason has been given: We should only need about 11K hours/month to run our regular testing. But a few ACME folks are accidentally running jobs in the batch instead of ACME queue. I'll remind them. This needs to be approved and the final allocation amount decided upon.
