GPU-acceleration of Plasma Turbulence Simulations for Fusion Energy
Abstract:
Attendees will learn about the role of CGYRO in simulating the confinement of plasma in toroidal fusion devices. CGYRO solves the gyrokinetic equations which describe the nonlinear, turbulent flow of plasma in toroidal geometry. It is compute and memory intensive, with high-fidelity cases running on leadership class HPC systems, like the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) Titan and Summit GPU-heavy supercomputers. Attendees will learn about the physics motivation, the software architecture, as well as the performance on leadership systems. In particular, we will discuss how CGYRO was designed and implemented to make good use of the tens of thousands of GPUs on leadership systems working in unison to provide simulations that bring us ever closer to fusion as an abundant clean energy source.
