Les architectures de calcul haute performance les plus récentes intègrent de plus en plus de nœuds de calcul qui contiennent eux-mêmes plus de cœurs. Les bus mémoires et les réseaux de communication sont soumis à un niveau d'utilisation criti

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 able to capture ion and electron turbulence that give rise to heat lo

A linearized multi-species collision operator valid for arbitrary masses and charges has been developed and implemented in the gyrokinetic code GYSELA [9]. This operator has all the required properties : it conserves particles, total momentum and ene

Recent high performance computing architectures come with more and more cores on a greater number of computational nodes. Memory buses and communication networks are facing critical levels of use. Programming parallel codes for those architectures re

Gyrokinetic modeling is appropriate for describing plasma turbulence in the core of Tokamaks, and the gyroaverage operator is a cornerstone of this approach. In a gyrokinetic code the gyroaveraging scheme needs to be accurate enough, but also require
