EZ: An Efficient, Charge Conserving Current Deposition Algorithm for Electromagnetic Particle-In-Cell Simulations
Klaus Steiniger, Rene Widera, Sergei Bastrakov +13
We present EZ, a novel current deposition algorithm for particle-in-cell (PIC) simulations. EZ calculates the current density on the electromagnetic grid due to macro-particle moti…
First Experiences in Performance Benchmarking with the New SPEChpc 2021 Suites
Holger Brunst, Sunita Chandrasekaran, Florina Ciorba +7
Modern HPC systems are built with innovative system architectures and novel programming models to further push the speed limit of computing. The increased complexity poses challeng…
Software publications with rich metadata: state of the art, automated workflows and HERMES concept
Stephan Druskat, Oliver Bertuch, Guido Juckeland +2
To satisfy the principles of FAIR software, software sustainability and software citation, research software must be formally published. Publication repositories make this possible…
Challenges Porting a C++ Template-Metaprogramming Abstraction Layer to Directive-based Offloading
Jeffrey Kelling, Sergei Bastrakov, Alexander Debus +10
HPC systems employ a growing variety of compute accelerators with different architectures and from different vendors. Large scientific applications are required to run efficiently…
Performance-Portable Many-Core Plasma Simulations: Porting PIConGPU to OpenPower and Beyond
Erik Zenker, René Widera, Axel Huebl +4
With the appearance of the heterogeneous platform OpenPower,many-core accelerator devices have been coupled with Power host processors for the first time. Towards utilizing their f…
Alpaka - An Abstraction Library for Parallel Kernel Acceleration
Erik Zenker, Benjamin Worpitz, René Widera +5
Porting applications to new hardware or programming models is a tedious and error prone process. Every help that eases these burdens is saving developer time that can then be inves…
