A massively parallel semi-Lagrangian solver for the six-dimensional Vlasov–Poisson equation

Katharina Kormann, Klaus Reuter, Markus Rampp
2019 The international journal of high performance computing applications  
At the same time, these solvers are challenged by the curse of dimensionality resulting in very high memory requirements, and moreover, requiring highly efficient parallelization schemes.  ...  We address the challenge of artificial time step restrictions due to the decomposition of the domain by introducing a blocked one-sided communication scheme for the purely electrostatic case and a rotating  ...  (www.gauss-centre.eu) for funding this project by providing computing time on the GCS Supercomputer SuperMUC at Leibniz Supercomputing Centre (LRZ, www.lrz.de) through project id pr53ri.  ...

D5.3: Updated Best Practices for HPC Procurement and Infrastructure

Andreas Johansson
2014 Zenodo  
Specific areas of interest are analysed in depth in terms of the market they belong to and the general HPC landscape, with a particular emphasis on the European point of view.  ...  Task 1 – Assessment of petascale systems – has performed a continuous market watch and analysis of trends in petascale HPC systems worldwide.  ...  This cannot be done by just scaling currently available codes, but by implementing a new paradigm for the development of advanced numerical methods to really exploit the intrinsic capabilities of the future  ...

Lattice Boltzmann Methods for Fluid-Dynamics in Relativistic Regimes

Alessandro Gabbana, Bergische Universität Wuppertal
2019
To give an example, we present results of simulations solving the Riemann problem for a quark-gluon plasma, showing good agreement with previous results obtained using other solvers present in the literature  ...  In this thesis work we present the algorithmic derivation of a new class of Lattice Boltzmann Methods appropriate for the study of dissipative relativistic fluids.  ...  We use a Xeon E5-2630 processor to test the In- tel Haswell micro-architecture, a Xeon-Phi 7120P for the Knights Corner (KNC), a Xeon-Phi 7230 for the Knights Landing (KNL).  ...
