The JOREK non-linear extended MHD code and applications to large-scale instabilities and their control in magnetically confined fusion plasmas
M Hoelzl, GTA Huijsmans, SJP Pamela +50
JOREK is a massively parallel fully implicit non-linear extended MHD code for realistic tokamak X-point plasmas. It has become a widely used versatile code for studying large-scale…
Performance analysis and optimization of the JOREK code for many-core CPUs
T. B. Fehér, M. Hölzl, G. Latu +1
This report investigates the performance of the JOREK code on the Intel Knights Landing and Skylake processor architectures. The OpenMP scaling of the matrix construction part of t…
Targeting realistic geometry in Tokamak code Gysela
Nicolas Bouzat, Camilla Bressan, Virginie Grandgirard +2
In magnetically confined plasmas used in Tokamak, turbulence is responsible for specific transport that limits the performance of this kind of reactors. Gyrokinetic simulations are…
Dynamic Load Balancing for PIC code using Eulerian/Lagrangian partitioning
Marc Sauget, Guillaume Latu
This document presents an analysis of different load balance strategies for a Plasma physics code that models high energy particle beams with PIC method. A comparison of different…
Optilization of the gyroaverage operator based on hermite interpolation
F Rozar, C Steiner, G Latu +5
Gyrokinetic modeling is appropriate for describing Tokamak plasma turbulence, and the gyroaverage operator is a cornerstone of this approach. In a gyrokinetic code, the gyroaveragi…
Evaluating kernels on Xeon Phi to accelerate Gysela application
G. Latu, M. Haefele, J. Bigot +3
This work describes the challenges presented by porting parts ofthe Gysela code to the Intel Xeon Phi coprocessor, as well as techniques used for optimization, vectorization and tu…
