Gyrokinetic simulation of fusion plasma

Idomura, Yasuhiro

We review gyrokinetic simulations of turbulent fusion plasmas. First, the five dimensional (5D) gyrokinetic model is presented, and its numerical approaches, namely, Lagrangian and Eulerian approaches are explained. Second, the gyrokinetic toroidal 5D Eulerian code GT5D is presented, and novel exascale computing techniques on the latest many core and GPU platforms are discussed. Third, the current petascale numerical experiments on ion temperature gradient turbulence are presented, and the target issues in the future exascale numerical experiments on FUGAKU are discussed.
