Ordering Methods for Sparse Matrices.

Abstract

Five tasks are defined: creation of a comprehensive test matrix collection, analysis of the Hellerman-Rarick P4 algorithm, production of a P4 code, production of a diagnostic code, and comparative analysis of several algorithms using the test matrices and the diagnostic code. Status reports on the five tasks are given, relevant reports and publications of project personnel are listed and related sparse matrix activities are discussed. Work is progressing well on the project. A very promising and stable variation of the Hellerman-Rarick algorithm has been found and will be tested in the next phase of the project.
