Parleda: a Library for Parallel Processing in Computational Geometry Applications

ParLeda is a software library that provides the basic primitives needed for parallel implementation of computational geometry applications. It can also be used in implementing a parallel application that uses geometric data structures. The parallel model that we use is based on a new heterogeneous parallel model named HBSP, which is based on BSP and is introduced here. ParLeda uses two main lib...

An efficient load balancing strategy for grid-based branch and bound algorithm

The most popular parallelization approach of the branch and bound algorithm consists in building and exploring in parallel the search tree representing the problem being tackled. The deployment of such parallel model on a grid rises the crucial issue of dynamic load balancing. The major question is how to efficiently distribute the nodes of an irregular search tree among a large set of heteroge...

A Novel B and B Algorithm for a Unrelated Parallel Machine Scheduling Problem to Minimize the Total Weighted Tardiness

This paper presents a scheduling problem with unrelated parallel machines and sequencedependent setup times that minimizes the total weighted tardiness. A new branch-and-bound (B and B) algorithm is designed incorporating the lower and upper bounding schemes and several dominance properties. The lower and upper bounds are derived through an assignment problem and the composite dispatching rule ...

Dynamic Load Balancing for Parallel Interval-Newton Using Message Passing

Branch-and-prune (BP) and branch-and-bound (BB) techniques are commonly used for intelligent search in finding all solutions, or the optimal solution, within a space of interest. The corresponding binary tree structure provides a natural parallelism allowing concurrent evaluation of subproblems using parallel computing technology. Of special interest here are techniques derived from interval an...

Branch and Bound Based Load Balancing for Parallel Applications

Many parallel applications are highly dynamic in nature. In some, computation and communication patterns change gradually during the run; in others those characteristics change abruptly. Such dynamic applications require an adaptive load balancing strategy. We are exploring an adaptive approach based on multi-partition object-based decomposition, supported by object migration. For many applicat...
