Scaling and performance portability of the particle-in-cell scheme for plasma physics applications through mini-apps targeting exascale architectures
Sriramkrishnan Muralikrishnan, Matthias Frey, Alessandro Vinciguerra +5
We perform a scaling and performance portability study of the particle-in-cell scheme for plasma physics applications through a set of mini-apps we name "Alpine", which can make us…
On Boundary Conditions in the sub-mesh interaction of the Particle-Particle-Particle-Mesh Algorithm
Tim Wyssling, Andreas Adelmann
The Particle-Particle-Particle-Mesh algorithm elegantly extends the standard Particle-In-Cell scheme by direct summation of interaction that happens over distances below or around…
Sparse Grids based Adaptive Noise Reduction strategy for Particle-In-Cell schemes
Sriramkrishnan Muralikrishnan, Antoine J. Cerfon, Matthias Frey +2
We propose a sparse grids based adaptive noise reduction strategy for electrostatic particle-in-cell (PIC) simulations. Our approach is based on the key idea of relying on sparse g…
Global Sensitivity Analysis on Numerical Solver Parameters of Particle-In-Cell Models in Particle Accelerator Systems
Matthias Frey, Andreas Adelmann
Every computer model depends on numerical input parameters that are chosen according to mostly conservative but rigorous numerical or empirical estimates. These parameters could fo…
On Architecture and Performance of Adaptive Mesh Refinement in an Electrostatics Particle-In-Cell Code
Matthias Frey, Andreas Adelmann, Uldis Locans
This article presents a hardware architecture independent implementation of an adaptive mesh refinement Poisson solver that is integrated into the electrostatic Particle-In-Cell be…
The Dynamical Kernel Scheduler - Part 1
Andreas Adelmann, Uldis Locans, Andreas Suter
Emerging processor architectures such as GPUs and Intel MICs provide a huge performance potential for high performance computing. However developing software using these hardware a…
