A massively parallel adaptive fast-multipole method on heterogeneous architectures
massively parallel fast-multipole method heterogeneous architectures
2015/7/15
We present new scalable algorithms and an implementation of the kernel-independent fast multiple method (KIFMM), employing hybrid distributed memory message passing (via MPI) and shared memory/streami...
A Massively Parallel Adaptive Fast Multipole Method on Heterogeneous Architectures
Massively Parallel Adaptive Fast Multipole Method Heterogeneous Architectures
2015/7/14
We describe a parallel fast multipole method (FMM) for highly nonuniform distributions of particles. We employ both distributed memory parallelism (via MPI) and shared memory parallelism (via OpenMP a...
A PARALLEL SWEEPING PRECONDITIONER FOR HETEROGENEOUS 3D HELMHOLTZ EQUATIONS
Helmholtz time-harmonic sweeping preconditioner parallel
2015/7/14
A parallelization of a sweeping preconditioner for 3D Helmholtz equations without internal resonance is introduced and benchmarked for several challenging velocity models. The setup and application co...
Traveling waves in a one-dimensional heterogeneous medium
Traveling waves one-dimensional heterogeneous medium
2015/7/14
We consider solutions of a scalar reaction-diffusion equation of the ignition type with a random, stationary and ergodic reaction rate. We show that solutions of the Cauchy problem spread with a deter...
On the superimposition of heterogeneous traffic at large time scales
heterogeneous traffic scales
2010/11/24
Various empirical and theoretical studies indicate that cumulative network traffic is a Gaussian process. However, depending on whether the intensity at which sessions are initiated is large or small ...
Modeling micro-macro pedestrian counterflow in heterogeneous domains
Modeling micro-macro heterogeneous domains
2010/11/11
We present a micro-macro strategy able to describe the dynamics of crowds in heterogeneous media. Herein we focus on the example of pedestrian counterflow. The main working tools include the use of ma...
On Poisson bulk arrival queue: M^X/M/2/N with balking, reneging and heterogeneous servers
Heterogeneous servers batch arrival balking reneging
2010/9/10
The aim of this paper is to derive the analytical solution of the queue: M X/M/2/Nfor batch arrival system with balking, reneging and two heterogeneous servers. A modified queue discipline to the clas...
Propagation of torsional surface waves in heterogeneous half-space with irregular free surface
Torsional surface waves Irregularity Heterogeneous medium
2010/9/15
The effect of irregularity on the propagation of torsional surface waves in a heterogeneous, elastic half-space has been studied. The velocity equation has been derived. The velocities have been calcu...
Bandwidth allocation and QoS routing for heterogeneous networks
bandwidth allocation QoS routing blocking probability
2010/9/16
We present a bandwidth allocation scheme offering optimal solutions to the network optimization problem. The bandwidth allocation policy in class-based networks can be defined with the proportionally ...
