Performance Optimisation of Smoothed Particle Hydrodynamics Algorithms for Multi/Many-Core Architectures
Fabio Baruffa, Luigi Iapichino, Nicolay J. Hammer +1
We describe a strategy for code modernisation of Gadget, a widely used community code for computational astrophysics. The focus of this work is on node-level performance optimisati…
Turbulence and Vorticity in Galaxy Clusters Generated by Structure Formation
F. Vazza, T. W. Jones, M. Brüggen +4
Turbulence is a key ingredient for the evolution of the intracluster medium, whose properties can be predicted with high resolution numerical simulations. We present initial result…
Splotch: porting and optimizing for the Xeon Phi
Timothy Dykes, Claudio Gheller, Marzia Rivi +1
With the increasing size and complexity of data produced by large scale numerical simulations, it is of primary importance for scientists to be able to exploit all available hardwa…
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…
Constraining the efficiency of cosmic ray acceleration by cluster shocks
F. Vazza, M. Brueggen, D. Wittor +3
We study the acceleration of cosmic rays by collisionless structure formation shocks with ENZO grid simulations. Data from the FERMI satellite enable the use of galaxy clusters as…
Detecting the cosmic web with radio surveys
F. Vazza, M. Brueggen, C. Gheller +2
We study the challenges to detect the cosmic web at radio wavelengths with state-of-the-art cosmological simulations of extragalactic magnetic fields. The incoming generation of ra…
