چکیده

Parallel algorithms developed for CAD problems today suuer from three important drawbacks. First, they are machine speciic and tend to perform poorly on architectures other than the one for which they were designed. Second, they cannot use the latest advances in improved versions of the sequential algorithms for solving the problem. Third, the quality of results degrade signiicantly during parallel execution. In this paper we address these three problems for an important CAD application: standard cell placement. We have developed a new parallel placement algorithm that is portable across a range of MIMD parallel architectures. The algorithm is part of the ProperCAD project which allows the development and implementation of a parallel algorithm such that it can be executed on a wide variety of parallel machines without any change to the source. The parallel placement algorithm is based on an existing implementation of the sequential simulated annealing algorithm, TimberWolfSC 6.0 1].

An evaluation of parallel simulated annealing strategies with application to standard cell placement

Simulated annealing, a methodology for solving combinatorial optimization problems, is a very computationally expensive algorithm, and as such, numerous researchers have undertaken efforts to parallelize it. In this paper, we investigate three of these parallel simulated annealing strategies when applied to standard cell placement, specifically the TimberWolfSC placement tool. We have examined ...

Optimal Placement and Sizing of DGs and Shunt Capacitor Banks Simultaneously in Distribution Networks using Particle Swarm Optimization Algorithm Based on Adaptive Learning Strategy

Abstract: Optimization of DG and capacitors is a nonlinear objective optimization problem with equal and unequal constraints, and the efficiency of meta-heuristic methods for solving optimization problems has been proven to any degree of complex it. As the population grows and then electricity consumption increases, the need for generation increases, which further reduces voltage, increases los...
