GPU-Acceleration of the ELPA2 Distributed Eigensolver for Dense Symmetric and Hermitian Eigenproblems
Victor Wen-zhe Yu, Jonathan Moussa, Pavel Kůs +5
The solution of eigenproblems is often a key computational bottleneck that limits the tractable system size of numerical algorithms, among them electronic structure theory in chemi…
Temperature Isotropization in Solar Flare Plasmas due to the Electron Firehose Instability
Peter Messmer
The isotropization process of a collisionless plasma with an electron temperature anisotropy along an external magnetic field (, and with respect…
AI-Machine Learning-Enabled Tokamak Digital Twin
William Tang, Eliot Feibush, Ge Dong +9
In addressing the Department of Energy's April, 2022 announcement of a Bold Decadal Vision for delivering a Fusion Pilot Plant by 2035, associated software tools need to be develop…
The Minimum Bandwidth of Narrowband Spikes in Solar Flare Decimetric Radio Waves
Peter Messmer, Arnold O. Benz
The minimum and the mean bandwidth of individual narrowband spikes in two events in decimetric radio waves is determined by means of multi-resolution analysis. Spikes of a few tens…
On particle acceleration and trapping by Poynting flux dominated flows
Gunnar Paesold, Eric G. Blackman, Peter Messmer
Using particle-in-cell (PIC) simulations, we study the evolution of a strongly magnetized plasma slab propagating into a finite density ambient medium. Like previous work, we find…
High-sensitivity observations of solar flare decimeter radiation
Arnold O. Benz, Peter Messmer, Christian Monstein
A new acousto-optic radio spectrometer has observed the 1 - 2 GHz radio emission of solar flares with unprecedented sensitivity. The number of detected decimeter type III bursts is…
Photo-Guided Exploration of Volume Data Features
Mohammad Raji, Alok Hota, Robert Sisneros +2
In this work, we pose the question of whether, by considering qualitative information such as a sample target image as input, one can produce a rendered image of scientific data th…
Performance report and optimized implementations of Weather & Climate dwarfs on multi-node systems
Louis Douriez, Alan Gray, David Guibert +2
This document is one of the deliverable reports created for the ESCAPE project. ESCAPE stands for Energy-efficient Scalable Algorithms for Weather Prediction at Exascale. The proje…
Performance report and optimized implementation of Weather & Climate Dwarfs on GPU, MIC and Optalysys Optical Processor
Cyril Mazauric, Erwan Raffin, Xavier Vigouroux +6
This document is one of the deliverable reports created for the ESCAPE project. ESCAPE stands for Energy-efficient Scalable Algorithms for Weather Prediction at Exascale. The proje…
Apar-T: code, validation, and physical interpretation of particle-in-cell results
Mickaël Melzani, Christophe Winisdoerffer, Rolf Walder +4
We present the parallel particle-in-cell (PIC) code Apar-T and, more importantly, address the fundamental question of the relations between the PIC model, the Vlasov-Maxwell theory…
