For those of you unfamiliar with the local geography, this means a move of only a few hundred metres although RAL and Harwell report to entirely different managements and Government Departments. We are very happy with this move since our role in supporting users and projects on the SERC supercomputers (presently a CRAY XMP/4 and an IBM 3090/600 VF) will give us much more opportunity to do research than would have been the case under the increasingly profit-oriented regime at Harwell. We are, however, very pleased that we will maintain a harmonious working relationship with the Harwell Laboratory, in particular, we will continue our technical support for the Harwell Subroutine Library. Several readers of this digest have known something of our discussions and have provided varying degrees of support and encouragement. We would like to hereby record our thanks for their assistance. On practical matters our new coordinates will be: Numerical Analysis Group Central Computing Department Atlas Centre Rutherford Appleton Laboratory Didcot Oxon OX11 0QX England Laboratory number: +44-235-821900 FAX number: +44-235-445808 Those involved in the move (with email addresses and telephone numbers) are: Iain Duff isd@ib.rl.ac.uk +44-235-44-235-445803 or ext 5803 Nick Gould nimg@ib.rl.ac.uk +44-235-44-235-445801 or ext 5801 John Reid jkr@ib.rl.ac.uk +44-235-44-235-446493 or ext 6493 Jennifer Scott sct@ib.rl.ac.uk +44-235-44-235-445131 or ext 5131 Nick, John, and Jennifer will move on April 2nd, and Iain (because of involvement in a Harwell contract) on June 4th. Iain's email should be directed to na.duff@na-net.stanford.edu until that time. ------------------------------ From: Gene Golub Date: Sat, 31 Mar 1990 15:07:38 PST Subject: Stanford NA Reports Available The following reports are available though supplies are limited.

LANCZOS CENTENARY CELEBRATION AT NORTH CAROLINA STATE UNIVERSITY As a part of the Cornelius Lanczos Centenary Celebration at North Carolina State University,* the College of Physical and Mathematical Sciences will publish a volume of the collected published Lanczos papers, with translations. This volume, scheduled for publication December 1991, will also include commentaries, historical and biographical notes, and a biographical sketch. In addition to the historical value of this volume, the editors intend to make it a valuable reference for many areas of research in mathematical physics and computational mathematics. They also hope that it will be a source of inspiration for both beginning research students and senior researchers. While most readers will be aware of a number of Lanczos's contributions to mathematical physics and computational mathematics,** many may not know of his pioneering works in quantum theory and relativity. Also, many readers may not be aware of the scope and impact of some of his later works and some of its implications for present ongoing areas of research. The editors of this volume plan to contact researchers in physics, mathematics, computing, and engineering who can provide commentaries on the works of Lanczos for this volume. However, the editors will consider commentaries from anyone who has special knowledge about Lanczos or the application and extension of his methods and ideas. Contributions that are primarily biographical and historical should be sent to Dr. Barbara Gellai at the address given below. EDITORS: Moody T. Chu, William R.

C. State University several times during the 1960's. His book entitled: Space Through the Ages: The Evolution of Geometrical Ideas from Pythagoras to Hilbert and Einstein, Academic Press, New York, 1970, was based on a lecture course given at N. C. State in the Spring of 1968 while Lanczos was a visiting Professor of Physics and Mathematics. Several faculty members and students were strongly influenced by the ideas and methods of Lanczos. In particular, Professor William R. Davis remained in contact with Lanczos from the mid-1950's until his death in 1974. ** For the benefit of the reader less familiar with the works of Lanczos, we list the books he published. Some of these books are well known to students of mathematics and physics: The Variational Principles Discourse on Fourier Series of Mechanics (Oliver and Boyd, 1966). (Toronto, 1949; 4th ed., 1970) Applied Analysis Numbers Without End (Prentice-Hall, 1956) (Oliver and Boyd, 1968) Linear Differential Operators Space Through the Ages (Van Nostrand, 1961) (Academic Press, 1970) Albert Einstein and The Einstein Decade: 1905--1915 the Cosmic World Order (Elek Books Ltd., 1974) (Wiley, 1965) ------------------------------ From: Steve McCormick Date: Thu, 29 Mar 90 11:20:13 mst Subject: Multigrid Short Course in Denver MULTIGRID SHORT COURSE University of Colorado at Denver May 14-18, 1990 Principal Lecturer: Achi Brandt Supporting Lecturers: John Adams, William Briggs, Chaoqun Liu, Steve McCormick, John Ruge Purpose: To provide an understanding of the principles and procedures for multilevel methods, especially for partial differential equations, including new multilevel approaches in computational fluid dynamics.

The course is aimed at scientists in industry and academia who wish to learn about parallel computing and familiarize themselves through hands-on experience with a range of parallel computers. On the first day, some introductory lectures on vector and parallel architectures will be followed by a more detailed description of the parallel computers available to students on the course. These will include a BBN Butterfly, an Alliant FX/80, a TMC Connection Machine CM-2, an INTEL hypercube, a CRAY-2, and an IBM 3090/VF. The second day will examine techniques for programming these machines and tools available to assist in their use. These lectures will be followed by a discussion of basic numerical algorithms and software. The final day will address more large scale computing on such architectures, including solution of sparse equations, and will provide an opportunity for students to run their own codes on the machines. Throughout the course, there will be a strong emphasis on hands-on experience and it is the intention that students would finish the course with a basic knowledge of parallelism and how to appreciate, compare, and use a range of different parallel architectures. Instructors for the course are J. Dongarra, W. Jalby, A. Edelman, D. Levine, I. Duff, T. Davis, M. Arioli, D. Ruiz, M. Bergman and R. Tilch. There will be a registration fee of 5,9300 FFr (incl VAT) which is reduced to 3,558 FFr (incl VAT) for full-time students. This fee includes all course materials, access to computers, and lunches as well as all refreshment breaks. It would be helpful in planning hands-on sessions, if prospective participants could indicate immediately their interest and could register as soon as possible.
