Data-Centric Models for Multilevel Algorithms
07 Feb 2016 | | Contributor(s):: Samuel Guiterrez
Today, computational scientists must contend with a diverse set of supercomputer architectures that are capable of exposing unprecedented levels of parallelism and complexity. Effectively placing, moving, and operating on data residing in complex distributed memory hierarchies is quickly...
Discretization of Elliptic Differential Equations Using Sparse Grids and Prewavelets
04 Feb 2016 | | Contributor(s):: Christoph Pflaum
Sparse grids can be used to discretize second order elliptic differential equations on a d-dimensional cube. Using Galerkin discretization, we obtain a linear equation system with unknowns. The corresponding discretization error is in the -norm. A major difficulty in...
Ferroelectric BaTiO3 Nanowires: Synthesis, Properties, and Device Applications
out of 5 stars
12 Feb 2008 | | Contributor(s):: Zhaoyu Wang
One dimensional ferroelectric nanowires have attracted much attention due to its interests in fundamental physics and potential applications in Nanoelectromechanical Systems (NEMS), non-volatile ferroelectric memories, and sensors. Domain structure is the most important property of ferroelectric...
Geometric Multigrid for MHD Simulations with Nedelec Finite Elements on Tetrahedral Grids
02 Feb 2016 | | Contributor(s):: Chris Hansen
The Magneto-HydroDynamic (MHD) model is used extensively to simulate macroscopic plasma dynamics in Magnetic Confinement Fusion (MCF) devices. In these simulations, the span of time scales from fast wave dynamics to the desired evolution of equilibrium due to transport processes is large,...
Harnessing Solid-State Ionic Transport
14 Apr 2008 | | Contributor(s):: Keng Hsu
Metallic nanostructures are the essential components of a large number of high-performance electronic devices, plasmonic devices, as well as physical and chemical sensors. Fabrication of nano-scale metallic features with controlled geometry has so far relied on lithographic processes that are...
High Dimensional Uncertainty Quantification via Multilevel Monte Carlo
02 Feb 2016 | | Contributor(s):: Hillary Fairbanks
Multilevel Monte Carlo (MLMC) has been shown to be a cost effective way to compute moments of desired quantities of interest in stochastic partial differential equations when the uncertainty in the data is high-dimensional. In this talk, we investigate the improved performance of MLMC versus...
HPGMG: Benchmarking Computers Using Multigrid
02 Feb 2016 | | Contributor(s):: Jed Brown
HPGMG (https://hpgmg.org) is a geometric multigrid benchmark designed to measure the performance and versatility of computers. For a benchmark to be representative of applications, good performance on the benchmark should be sufficient to ensure good performance on most important applications...
Hub Snub: Removing Vertices with High Degree from Coarse-grid Correction
02 Feb 2016 | | Contributor(s):: Geoffry Sanders
Network scientists often employ numerical solutions to linear systems as subroutines of data mining algorithms. Due to the ill-conditioned nature of the systems, obtaining solutions with standard iterative methods is often prohibitively costly; current research aims to automatically construct...
