Prediction of the Inter-Node Communication Costs of a New Gyrokinetic Code with Toroidal Domain

Laurent Villard, Stephan Brunner, Emmanuel Lanti, Noé Thomas Elie Ohana, Claudio Gheller, Aaron Lewis Scheinberg

We consider the communication costs of gyrokinetic plasma physics simulations running at large scale. For this we apply virtual decompositions of the toroidal domain in three dimensions and additional domain cloning to existing simulations done with the OR ...

Supershear bursts in the propagation of a tensile crack in linear elastic material

Jean-François Molinari, Fabian Barras, René Carpaij

Since the early years of the linear elastic theory of fracture [linear elastic fracture mechanics (LEFM)], scientists have sought to understand and predict how fast cracks grow in a material or slip fronts propagate along faults. While shear cracks can tra ...

Distributed Learning of CNNs on Heterogeneous CPU/GPU Architectures

José Pedro Rebelo Ferreira Marques, Gabriel Falcao Paiva Fernandes

The convolutional neural networks (CNNs) have proven to be powerful classification tools in tasks that range from check reading to medical diagnosis, reaching close to human perception, and in some cases surpassing it. However, the problems to solve are be ...

Optical wave evolution due to interaction with elastic wave in a phoxonic crystal slab waveguide

Sina Khorasani

Phoxonic crystal as a means of guiding and confining electromagnetic and elastic waves has already attracted attentions. Lack of exact knowledge on how these two types of waves interact inside this crystal and how electromagnetic wave evolves through this ...

Acoustic monitoring of laboratory hydraulic fracture growth under stress and pore pressure

Brice Tanguy Alphonse Lecampion, Thomas Emmanuel Blum

Fluid-driven fracturing is used in a wide range of applications, including oil and gas extraction, geothermal energy recovery, and CO2 sequestration. In order to efficiently fracture the targeted rock formation, theoretical models provide estimates of the ...

The finite element square reduced (FE2R) method with GPU acceleration: towards three-dimensional two-scale simulations

Max Ludwig Hodapp

The FE2 method is a renown computational multiscale simulation technique for solid materials with fine-scale microstructure. It allows for the accurate prediction of the mechanical behavior of structures made of heterogeneous materials with nonlinear mater ...

The role of elastic waves during dynamic rupture of heterogeneous interfaces

Jean-François Molinari, Fabian Barras

Along a planar interface bonding two solids made of Homalite, we simulate rupture events in the presence of a unique tougher inclusion with insights on the influence of its geometry and fracture properties. Our study is then pursued with fracture planes ma ...

Execution Trace Graph Based Multi-criteria Partitioning of Stream Programs

Marco Mattavelli, Simone Casale Brunet, Endri Bezati, Malgorzata Maria Michalska

One of the problems proven to be NP-hard in the field of many-core architectures is the partitioning of stream programs. In order to maximize the execution parallelism and obtain the maximal data throughput for a streaming application it is essential to fi ...

Isogeometric numerical dispersion analysis for two-dimensional elastic wave propagation

Alfio Quarteroni, Luca Dede', Christoph Jäggli

In this paper, we carry out a numerical dispersion analysis for the linear two-dimensional elastodynamics equations approximated by means of NURBS-based Isogeometric Analysis in the framework of the Galerkin method; specifically, we consider the analysis o ...
