SPEC ENV2002: Environmental Simulation Benchmarks

SPEC ENV2002: Environmental Simulation Benchmarks Wesley Jones [email protected] SPEC ENV2002 Based on the WRF weather model, a state-of-theart, non-hydrostatic mesoscale weather model, see http://www.wrf-model.org The WRF (Weather Research and Forecasting) Modeling System development project is a multiyear project being undertaken by several agencies. Members of the WRF Scientific Board include representatives from EPA, FAA, NASA, NCAR, NOAA, NRL, USAF and several universities.

SPEC ENV2002 SPEC HPG integrated version 1.2.1 of the WRF weather model into the SPEC tools for building, running and verifying results. This means that the benchmark runs on more systems than WRF has officially been ported to. Results available soon @ www.spec.org SPEC ENV2002 SPEC ENV2002 Scaling 80

SPEC ENV2002 Preprocessing directives are used within the SPEC runtools and WRF source code to create executables that can run in serial mode or in parallel mode using industry standard parallel APIs, OpenMP, MPI or mixed MPI-OpenMP (Hybrid). NetCDF is used for I/O. Benchmarkers, use a standard distribution of NetCDF and link it into the SPEC ENV2002 benchmark. SPEC ENV2002

The WRF datasets used in SPEC ENV2002 are created using the WRF Standard Initialization (SI) software and standard sets of data used in numerical weather prediction. The benchmark runs use restart files that are created after the model has run for several simulated hours. This ensures that cumulus and microphysics schemes are fully developed during the benchmark runs. SPEC ENV2002 The initially: Medium data, SPECenvM2002
