I am enclosing a short information about the book. I am wishing a Good New Year to all of you. Many wishes for successes in 1992. Zahari Zlatev Zahari Zlatev: "Computational Methods for General Sparse Matrices", Mathematics and Its Applications, Vol. 65, Kluwer Academic Piblishers, Dordrecht-Boston-London, 1991. Sparse matrices often arise in the numerical analysis of large mathematical problems in many fields of science and engineering. The usual approach adopted in the treatment of sparse matrices is to consider either direct methods or iterative methods. This volume attempts to build a bridge between these methods. The first part (Chapters 1 -3) reviews and discusses common principles concerning the treatment of sparsity. The second part (Chapters 4-11) studies how sparsity can be exploited in the solution of linear algebraic equations. Related problems are also considered, such as solving linear least squares problems by augmentation, calculating approximate solutions of systems of ordinary differential equations, and estimating condition numbers of sparse matrices. This part concludes with a description and testing of parallel methods for sparse matrices. The third part (Chapters 12-16) is devoted to orthogonalization methods and their use in the solution of large linear least squares problems. Much of the material included is new and has not previously appeared in book form. The treatment assumes familiarity with only a few fundamental concepts from numerical linear algebra. Contents: 1. Exploiting sparsity, 2. Storage schemes, 3. General scheme for linear algebraic problems, 4. Pivotal strategies for Gaussian elimination, 5. Use of iterative refinement in the GE process, 6. Implementation of the algorithms, 7. Solving linear least squares equations by augmentation, 8. Sparse matrix technique for ordinary differential equations, 9. Condition number estimators in a sparse matrix software, 10. Parallel direct solvers, 11. parallel orthomin for general sparse matrices, 12. Ortho- gonalization methods, 13. Two storage schemes for Givens plane rotations, 14. Pivotal strategies for Givens plane rotations, 15. Iterative refinement after the plane rotations, 16. Preconditioned conjugate gradients for Givens plane rotations, References, Author index, Subject index.

The complexities come from one or more of the following: the system of equations; the boundary conditions; the geometry of the problem; the structure of the solution; and the architecture of the machine on which the computation is to be performed. The papers in this special session describe the use of symbolic computing techniques to address these problems. Other Special Sessions: J.R. Rice, Parallel Methods for PDEs.

NASA has an interest in applying this increased computational capability to grand challenges in computational aerosciences. In particular, NASA is interested in doing multidisciplinary (e.g., aerodynamics, structural mechanics, controls, reacting chemistry, propulsion, etc.) modeling for aerospace vehicle analysis and optimization. To do this, advances are required in advanced modeling techniques, parallel systems software, and hardware architecture for the computational engine and overall system. Testbed systems currently available for use include a 128-node Touchstone Gamma (iPSC/860), a 528-node Touchstone Delta, and a Connection Machine 2.
