Strong Scaling of OpenACC enabled Nek5000 on several GPU based HPC systems
Jonathan Vincent, Jing Gong, Martin Karp +11
We present new results on the strong parallel scaling for the OpenACC-accelerated implementation of the high-order spectral element fluid dynamics solver Nek5000. The test case con…
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…
Gyrokinetic Simulations on Many- and Multi-core Architectures with the Global Electromagnetic Particle-In-Cell Code ORB5
Noé Ohana, Claudio Gheller, Emmanuel Lanti +3
Gyrokinetic codes in plasma physics need outstanding computational resources to solve increasingly complex problems, requiring the effective exploitation of cutting-edge HPC archit…
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…
A portable platform for accelerated PIC codes and its application to GPUs using OpenACC
F. Hariri, T. M. Tran, A. Jocksch +6
We present a portable platform, called PIC_ENGINE, for accelerating Particle-In-Cell (PIC) codes on heterogeneous many-core architectures such as Graphic Processing Units (GPUs). T…
