Title RALPAR-LIB : a multilevel partitioning library
Contributors
Abstract This report describes the multilevel partitioning methods which have been implemented in the software package Ralpar. Such methods address the problem of finding an efficient partitioning of a mesh for parallel processing in a reasonable time. A graph representation of the connectivity of a mesh is condensed through a number of levels to give a smaller problem that can be partitioned quickly. Kernighan and Lin refinement is used to improve the partition on intermediate levels. A library interface to these partitioning routines is described, the Ralpar multilevel library (RPMLL). Some examples are given to illustrate the performance of this implementation of multilevel methods.
