1.4    Opportunities for WRF Model Acceleration

Michalakes, John, National Renewable Energy Laboratory, and Andrew Porter, Daresbury Laboratory, UK

This presentation will describe efforts to improve WRF performance and scaling by exploiting parallelism at the node level and in high-performance scalable I/O systems.  At the node level, progress adapting WRF to use many and multi-core processors is discussed, including the new Many Integrated Core (MIC) architecture (subject to non-disclosure restrictions). Also, I/O improvements developed at Daresbury Laboratory, U.K.  that combine parallel NetCDF with WRF "quilting" are described with results and usage information.
