Abstract of GYGLES Project

Global electromagnetic gyrokinetic PIC simulations on the HPC-FF facility with the linear code GYGLES will contribute significantly to the establishment of the PIC method as a reliable tool for simulations of ITER-relevant phenomena such as Alfvèn eigenmodes, kink, sawteeth and microtearing modes. The code is highly optimised and scales very well on massive parallel computers. Nevertheless, simulations in reactor-relevant plasmas will lead to an increase in required computing power of about two orders of magnitude, which could be provided by HPC-FF. The simulations can be extended to a non-linear regime employing the code EUTERPE. These simulations will provide a necessary basis for further exploration of the nonlinear electromagnetic physics in non-axisymmetric (stellarator) magnetic geometries.
