A Modular Workflow for Performance Benchmarking of Neuronal Network Simulations
Jasper Albers, Jari Pronold, Anno Christopher Kurth +9
Modern computational neuroscience strives to develop complex network models to explain dynamics and function of brains in health and disease. This process goes hand in hand with ad…
Routing brain traffic through the von Neumann bottleneck: Efficient cache usage in spiking neural network simulation code on general purpose computers
Jari Pronold, Jakob Jordan, Brian J. N. Wylie +3
Simulation is a third pillar next to experiment and theory in the study of complex dynamic systems such as biological neural networks. Contemporary brain-scale networks correspond…
Routing brain traffic through the von Neumann bottleneck: Parallel sorting and refactoring
Jari Pronold, Jakob Jordan, Brian J. N. Wylie +3
Generic simulation code for spiking neuronal networks spends the major part of time in the phase where spikes have arrived at a compute node and need to be delivered to their targe…
Lattice simulations of the QCD chiral transition at real baryon density
Szabolcs Borsanyi, Zoltan Fodor, Matteo Giordano +4
State-of-the-art lattice QCD studies of hot and dense strongly interacting matter currently rely on extrapolation from zero or imaginary chemical potentials. The ill-posedness of n…
On momentum operators given by Killing vectors whose integral curves are geodesics
Thomas Schürmann
We consider momentum operators on intrinsically curved manifolds. Given that the momentum operators are Killing vector fields whose integral curves are geodesics, it is shown that…
Benchmarking Advantage and D-Wave 2000Q quantum annealers with exact cover problems
Dennis Willsch, Madita Willsch, Carlos D. Gonzalez Calaza +4
We benchmark the quantum processing units of the largest quantum annealers to date, the 5000+ qubit quantum annealer Advantage and its 2000+ qubit predecessor D-Wave 2000Q, using t…
Polarisation-dependent single-pulse ultrafast optical switching of an elementary ferromagnet
Hanan Hamamera, Filipe Souza Mendes Guimarães, Manuel dos Santos Dias +1
The ultimate control of magnetic states of matter at femtosecond (or even faster) timescales defines one of the most pursued paradigm shifts for future information technology. In t…
Herschel observations of extraordinary sources: Full Herschel/HIFI molecular line survey of Sagittarius B2(M)
T. Möller, P. Schilke, A. Schmiedeke +5
We present a full analysis of a broadband spectral line survey of Sagittarius B2 (Main), one of the most chemically rich regions in the Galaxy located within the giant molecular cl…
GPU-accelerated simulations of quantum annealing and the quantum approximate optimization algorithm
Dennis Willsch, Madita Willsch, Fengping Jin +2
We study large-scale applications using a GPU-accelerated version of the massively parallel Jülich universal quantum computer simulator (JUQCS--G). First, we benchmark JUWELS Boost…
Quantum versus Classical Dynamics in Spin Models: Chains, Ladders, and Square Lattices
Dennis Schubert, Jonas Richter, Fengping Jin +3
We present a comprehensive comparison of spin and energy dynamics in quantum and classical spin models on different geometries, ranging from one-dimensional chains, over quasi-one-…
Polarized proton acceleration in ultra-intense laser interaction with near critical density plasmas
X. F. Li, P. Gibbon, A. Hützen +4
The production of polarized proton beams with multi-GeV energies in ultra-intense laser interaction with targets is studied with three-dimensional Particle-In-Cell simulations. A n…
Twelve Ways To Fool The Masses When Giving Parallel-In-Time Results
Sebastian Goetschel, Michael Minion, Daniel Ruprecht +1
Getting good speedup -- let alone high parallel efficiency -- for parallel-in-time (PinT) integration examples can be frustratingly difficult. The high complexity and large number…
Lattice QCD equation of state at finite chemical potential from an alternative expansion scheme
S. Borsanyi, Z. Fodor, J. N. Guenther +6
Taylor expansion of the equation of state of QCD suffers from shortcomings at chemical potentials . First, one faces difficulties inherent in performing such an…
Influence of relativistic rotation on the confinement/deconfinement transition in gluodynamics
V. V. Braguta, A. Yu. Kotov, D. D. Kuznedelev +1
In this paper we consider the influence of relativistic rotation on the confinement/deconfinement transition in gluodynamics within lattice simulation. We perform the simulation in…
Garden optimization problems for benchmarking quantum annealers
Carlos D. Gonzalez Calaza, Dennis Willsch, Kristel Michielsen
We benchmark the 5000+ qubit system Advantage coupled with the Hybrid Solver Service 2 released by D-Wave Systems Inc. in September 2020 by using a new class of optimization proble…
Orbital magnetoelectric effect in zigzag nanoribbons of p-band systems
Tarik P. Cysne, Filipe S. M. Guimarães, Luis M. Canonico +2
Profiles of the spin and orbital angular momentum accumulations induced by a longitudinally applied electric field are explored in nanoribbons of -band systems with a honeycomb…
P-wave nucleon-pion scattering amplitude in the channel from lattice QCD
Giorgio Silvi, Srijit Paul, Constantia Alexandrou +9
We determine the resonance parameters using lattice QCD and the Lüscher method. The resonance occurs in elastic pion-nucleon scattering with in the isospin $I…
