On the Performance and Energy Efficiency of the PGAS Programming Model on Multicore Architectures
Jérémie Lagravière, Johannes Langguth, Mohammed Sourouri +2
Using large-scale multicore systems to get the maximum performance and energy efficiency with manageable programmability is a major challenge. The partitioned global address space…
Controlling spin current polarization through non-collinear antiferromagnetism
T. Nan, C. X. Quintela, J. Irwin +20
The spin-Hall effect describes the interconversion of charge currents and spin currents, enabling highly efficient manipulation of magnetization for spintronics. Symmetry condition…
The Casimir effect for fermionic currents in conical rings with applications to graphene ribbons
S. Bellucci, I. Brevik, A. A. Saharian +1
We investigate the combined effects of boundaries and topology on the vacuum expectation values (VEVs) of the charge and current densities for a massive 2D fermionic field confined…
Saturation of radiative heat transfer due to many-body thermalization
Ivan Latella, Riccardo Messina, Svend-Age Biehs +2
Radiative heat transfer between two bodies saturates at very short separation distances due to the nonlocal optical response of the materials. In this work, we show that the presen…
A long short-term memory embedding for hybrid uplifted reduced order models
Shady E. Ahmed, Omer San, Adil Rasheed +1
In this paper, we introduce an uplifted reduced order modeling (UROM) approach through the integration of standard projection based methods with long short-term memory (LSTM) embed…
A multimesh finite element method for the Navier-Stokes equations based on projection methods
Jørgen S. Dokken, August Johansson, André Massing +1
The multimesh finite element method is a technique for solving partial differential equations on multiple non-matching meshes by enforcing interface conditions using Nitsche's meth…
Anomalous Diffusion in Systems with Concentration-Dependent Diffusivity
Alex Hansen, Eirik G. Flekkøy
We show analytically that there is anomalous diffusion when the diffusion constant depends on the concentration as a power law with a positive exponent or a negative exponent with…
Uniform quantized electron gas: Radiation corrections
Johan S. Høye, Enrique Lomba
In this paper we analyze how radiation effects influence the correlation functions, the excess energy, and in turn the electron correlation energy of the quantized electron gas at…
GPU Computing with Python: Performance, Energy Efficiency and Usability
Håvard H. Holm, André R. Brodtkorb, Martin L. Sætra
In this work, we examine the performance, energy efficiency and usability when using Python for developing HPC codes running on the GPU. We investigate the portability of performan…
Robust Morph-Detection at Automated Border Control Gate using Deep Decomposed 3D Shape and Diffuse Reflectance
Jag Mohan Singh, Raghavendra Ramachandra, Kiran B. Raja +1
Face recognition is widely employed in Automated Border Control (ABC) gates, which verify the face image on passport or electronic Machine Readable Travel Document (eMTRD) against…
Multimodal Prediction based on Graph Representations
Icaro Cavalcante Dourado, Salvatore Tabbone, Ricardo da Silva Torres
This paper proposes a learning model, based on rank-fusion graphs, for general applicability in multimodal prediction tasks, such as multimodal regression and image classification.…
Magnon-mediated superconductivity on the surface of a topological insulator
Eirik Erlandsen, Arne Brataas, Asle Sudbø
We study superconductivity on the surface of a topological insulator, mediated by magnetic fluctuations in an adjacent ferromagnetic or antiferromagnetic insulator. Superconductivi…
Enhanced multiscale restriction-smoothed basis (MsRSB) preconditioning with applications to porous media flow and geomechanics
Sebastian B. M. Bosma, Sergey Klevtsov, Olav Møyner +1
A novel method to enable application of the Multiscale Restricted Smoothed Basis (MsRSB) method to non M-matrices is presented. The original MsRSB method is enhanced with a filteri…
Hydrothermal Scheduling in the Continuous-Time Framework
Christian Øyn Naversen, Arild Helseth, Bosong Li +3
Continuous-time optimization models have successfully been used to capture the impact of ramping limitations in power systems. In this paper, the continuous-time framework is adapt…
Angular Momentum Conservation and Phonon Spin in Magnetic Insulators
Andreas Rückriegel, Simon Streib, Gerrit E. W. Bauer +1
We develop a microscopic theory of spin-lattice interactions in magnetic insulators, separating rigid-body rotations and the internal angular momentum, or spin, of the phonons, whi…
EPIC: An Energy-Efficient, High-Performance GPGPU Computing Research Infrastructure
Magnus Själander, Magnus Jahre, Gunnar Tufte +1
The pursuit of many research questions requires massive computational resources. State-of-the-art research in physical processes using simulations, the training of neural networks…
Phonon-mediated superconductivity in doped monolayer materials
Even Thingstad, Akashdeep Kamra, Justin W. Wells +1
Insight into why superconductivity in pristine and doped monolayer graphene seems strongly suppressed has been central for the recent years' various creative approaches to realize…
RVSDG: An Intermediate Representation for Optimizing Compilers
Nico Reissmann, Jan Christian Meyer, Helge Bahmann +1
Intermediate Representations (IRs) are central to optimizing compilers as the way the program is represented may enhance or limit analyses and transformations. Suitable IRs focus o…
Power System Decarbonization: Impacts of Energy Storage Duration and Interannual Renewables Variability
Mehdi Jafari, Magnus Korpas, Audun Botterud
Decarbonization of the electricity sector is one of the major measures in slowing down the pace of climate change. In this paper, we analyze the impacts of energy storage systems (…
