Two researchers in the Mathematics and Computer Science Division at Argonne National Laboratory will participate in computational research projects involving advanced simulation and analysis on the U.S. Department of Energy leadership-class computers.
The projects, selected competitively based on their potential to advance scientific discovery, were awarded the supercomputer time through the DOE Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program.
Robert Jacob will participate in a new project titled “Accelerated Climate Modeling for Energy (ACME).” The project—awarded 89 million processor hours on the Cray XC40 at Argonne and 90 million processor hours on the Cray XK7 at Oak Ridge—focuses on two science areas: the water cycle and cryosphere systems. For the first area, the goal is to simulate the changes in the hydrological cycle with a specific focus on precipitation and surface water in regions such as the western United States and the headwaters of the Amazon. For the second area, the objective is to examine the near-term risk of initiating the dynamic instability and onset of the collapse of the Antarctic ice sheet due to rapid melting by adjacent warming waters.
Pete Beckman will continue to work with colleagues from universities and several other national laboratories on the project “Performance Evaluation and Analysis Consortium (PEAC) End Station,” led by Lawrence Berkeley National Laboratory. The researchers are developing new programming models, runtime systems, and tools and are conducting system evaluations and application analysis that support computational science on leadership=computing platforms. The project team will use both the Argonne Mira (45 million processor hours) and the Cray XC40 and Cray XK40 (44 million processor hours).
