The Intel® Parallel Computing Center (Intel® PCC) for Weather and Climate Simulation (IPCC-WACS) is a multi-institutional collaboration between the University of Colorado, Boulder, and the National Center for Atmospheric Research. The goals of this collaborative center are to promote the discovery of new methods for optimizing the performance of weather and climate models on Intel Xeon® and Intel Xeon Phi™ coprocessor hardware, and to accelerate the adoption of these optimizations in key weather and climate community models. The new center will focus on three prominent community models: the Weather Research and Forecast (WRF) model, the Community Earth System Model (CESM), and the Model for Prediction Across Scales (MPAS). Combined together, these models provide comprehensive modeling capabilities at local, regional and planetary scales. Advances in efficiency and parallelization made through this partnership will position the community to take advantage of emerging Intel based architectures that we expect to be prominent in HPC systems in the next 3-5 years.
Primary activities of IPCC-WACS include:
- Systematic performance and profiling studies of CESM, WRF, and MPAS to identify performance bottlenecks and improvements that will be needed to take advantage of new Intel® architecture.
- Modify these applications and verify performance improvements and numerical accuracy across Xeon and Xeon Phi™ processors
- Work with community model development teams to integrate these changes into future production releases.
- Disseminate results and lessons learned in the form of presentations, workshops, conferences, and new graduate-level coursework.
- Effective Barrier Synchronization on Intel® Xeon Phi™ coprocessor
