Structure-preserving Geometric Algorithms & Exascale Computing

Dr. Hong Qin
PPPL and University of Science and Technology of China

It is difficult for the standard numerical algorithms currently adopted by the plasma physics community to meet the long-term accuracy and fidelity requirement in large-scale numerical studies of multi-scale, complex dynamics of plasmas in space and laboratory. To overcome this difficulty, researchers have been actively developing a new generation of numerical algorithms that preserve the geometric structures, such as the symplectic structure, of theoretical models in plasma physics. Since 2008, the superiorities of these geometric algorithms in terms of long-term accuracy and fidelity have been demonstrated by many applications. It is our vision that future numerical capabilities, especially those suitable for exascale computing, in plasma physics will be based on structure-preserving geometric algorithms.
