On a parallel partitioning technique for use with conservative parallel simulation

Abstract

The major goal of this work has been to develop an implementation of a parallel partitioning algorithm which is suitable for use in a conservatively synchronized Parallel Discrete Event Simulation (PDES) environment. Effective partitioning is essential for performance and capacity consideration, for any PDES problem. The performance of the partitioning algorithm is very important, to the overall simulation performance. There are two possible approaches to improve performance for the partitioning step: algorithm modifications; and parallelize the partitioning algorithm (Fiduccia and Mattheyses, 1982) is developed. The basic algorithm has been modified, first for parallel execution with a similar quality of final partition; and then further modified to increase the parallelism of the algorithm, at the expense of partition quality.
