Improved O(N) Neighbor List Method Using Domain Decomposition and Data Sorting

Yao Z-H, Wang J-S., Cheng M., National University of Singapore, SG

The conventional Verlet table neighbor list algorithm is improved to reduce the number of unnecessary interatomic distance calculation in molecular simulations involving many atoms. Both of the serial and parallelized performance of molecular dynamics simulation [...]

Parallel Dynamic Load Balancing for Semiconductor Device Simulations on a Linux Cluster

Li Y., Lin S-S., Liu J-L., Lin S-S., Yu S-M., Liu J-L., Chao T-S., Sze S.M., National Chiao Tung University, TW

A parallel dynamic load balancing for 2-D and 3-D semiconductor device simulations is proposed. The hydrodynamic and drift diffusion models are discretized and solved with finite volume (box) and monotone iterative methods. Dynamic load balancing [...]

A Combined DSMC/Meshless Technique for Multiscale Analysis of Microfluidic Filters

Aktas O., Aluru N.R., University of Illinois at Urbana-Champaign, US

A multiscale method that couples a meshless Stokes solver and a DSMC simulator is reported. The method is based on overlapped Schwarz alternating method with Dirichlet-Dirichlet type boundary conditions for domain decomposition and meshless interpolation

Parallel Domain Decomposition Applied to 3D Poisson Equation for Gradual HBT

García-Loureiro A.J., Pena T.F., López-González J.M, Prat Viñas Ll., Univ. Santiago de Compostela, ES

This paper presents the implementation of a parallel solver for the 3D Poisson equation applied to gradual HBT simulation in a memory distributed multiprocessor. The Poisson equation was discretized using a finite element method (FEM) [...]
