Optimised allgatherv, reduce_scatter and allreduce communication in message-passing systems

Andreas Jocksch, Noe Ohana, Emmanuel Lanti +2

Collective communications, namely the patterns allgatherv, reduce_scatter, and allreduce in message-passing systems are optimised based on measurements at the installation time of…

Nonlinear dynamics of energetic-particle driven geodesic acoustic modes in ASDEX Upgrade

I. Novikau, A. Biancalani, A. Bottino +9

Turbulence in tokamaks generates radially sheared zonal flows. Their oscillatory counterparts, geodesic acoustic modes (GAMs), appear due to the action of the magnetic field curvat…

ORB5: a global electromagnetic gyrokinetic code using the PIC approach in toroidal geometry

E. Lanti, N. Ohana, N. Tronko +20

This paper presents the current state of the global gyrokinetic code ORB5 as an update of the previous reference [Jolliet et al., Comp. Phys. Commun. 177 409 (2007)]. The ORB5 code…
