Lebedev As it was said by the famous Sobolev, for computational mathematics Banach spaces are as indispensable as computers. New book of (former Sobolev's PhD student) Prof. V.I.Lebedev (Institute for Numerical Mathematics, Russian Academy of Sciences) "An Introduction to Functional Analysis and Computational Mathematics", has been published recently by Birkhauser (ISBN 0-8176-3888-1) The book is based on the lectures read for many years by the author in Moscow Institute of Physics and Technology (the famous "PhysTech"). It is a perfect combination of real-life numerical techniques and advanced theoretical bases. The Vishik-Lax-Milgram theorem, embedding theorems, Galerkin and Ritz methods for operator equations, ... are just some sketches of material presented. "I tried to keep my book easily readable, so there is no one proof more than 1 page", he told. The book is not only high-quality textbook, but also of high interest for experts in many fields of Numerical Analysis. For example, you may find there how to build up endlessly continuable and optimal two-term Chebyshev iteration for linear system solution, or, how to integrate stiff ODEs by explicit methods (it is not a joke, Lebedev's explicit stiff ODE codes DUMKA are proved to be quit robust, they have been succesfully used for several years). Prof. V.I.Lebedev is directly reached through nucrect@inm.ras.ru; also, Fortran77 code of DUMKA is freely available. ------------------------------ From: R. Baker Kearfott Date: Tue, 26 Nov 1996 23:12:29 -0600 Subject: New Nonlinear Equations / Global Optimization Book My book, "Rigorous Global Search: Continuous Problems," ISBN: 0-7923-4238-0, is now available from Kluwer Academic Publishers. The book treats research results and software in verified solution of nonlinear systems and global optimization. It has an extensive introduction to general theory and techniques. A table of contents and preface are available, in Postscript form, at: http://interval.usl.edu/books/table-of-contents-and-preface.ps The index is available, in Postscript form, at: http://interval.usl.edu/books/index.ps The summary on the back cover and an order form are available at: http://interval.usl.edu/books/Rigorous-Global-Search.txt Special pricing for use as a course text is available. I am also making my research code, in Fortran 90, available. This code contains automatic differentiation, as described in the book, nonlinear systems code, and code for constrained and unconstrained optimization. Software engineering for neat packaging continues to proceed, and different portions are in different states of polish. The elementary portions (such as the interval arithmetic module) are in the highest state of completion. The nonlinear systems solver is in relatively good shape, while improvements are continuing on the general constrained global optimization part. The package includes a significant collection of test problems, written simply in Fortran 90. Executables for Windows 95 machines (486 or higher) and Sun Sparc machines are available. For source and executables, see: ftp://interval.usl.edu/pub/interval_math/Fortran_90_software/INTOPT_90/"> All of the above URL's can be accessed from my home page at: http://interval.usl.edu/kearfott.html For alternate ordering instructions, see: http://www.wkap.nl Best regards, R.

Because of problems scheduling the conference into the Center it was necessary to change either the date or the venue. We have decided to hold the conference from May 27-May 30, 1997. Check- in at Asilomar will be after 3pm on May 27, with check-out by 12 noon on May 30. As you know radial basis functions are becoming widely used in neural networks, approximations, interpolation, partial and integral differential equations, etc. We anticipate that this conference will be an excellent opportunity for theoreticians and practitioners to meet and exchange ideas in a setting conducive to in-depth discussion. The Asilomar Conference Center is located on the tip of the Monterey Peninsula within a short walking distance from the beach. This center offers conference rooms, with guest rooms and full dining services under the American plan at a very reasonable cost. Asilomar is within a short distance of many favorite tourist spots such as the Monterey Bay Aquarium, Carmel-by-the- Sea, the Big Sur coastline, and Point Lobos. Although it is always tourist season on the Monterey Peninsula, the last week of May should be relatively uncrowded. We hope to keep registration costs low, below $170. More information regarding the cost of accommodations will be forthcoming, but depending on the type of room, a room and meals for the three days of the conference should be no more than about $250, single occupancy, with a substantial saving per person for double occupancy. For those wanting to do so, an attempt to facilitate room-sharing will be made. A few larger rooms are available. It is possible to stay elsewhere, although there is an additional charge of $7 per day for participants not staying at the center, and arrangements for meals (perhaps at Asilomar) will be necessary. If you are not presently on our distribution list, please send us your email address (or regular mail, if necessary), so we can be sure you get the housing form and other information about the meeting.

Would you like to be able to write architecture-independent but efficient parallel code ? Have you tried MPI and PVM, and now want a simpler alternative ? Are you fed up with dead lock in your code ? Or, maybe you've heard of Bulk Synchronous Parallel (BSP) programming or the BSPlib proposals for BSP primitives, available as part of the BSP Programming Environment being developed by Oxford Parallel, and want to know more ? Then this could be the course for you! The Bulk Synchronous Parallel (BSP) model unlocks the potential of parallel computing. It allows developers to write software that is architecture-independent and yet takes advantage of whatever parallel computing facilities a particular machine can offer. An advantage of BSPlib, an implementation of the BSP approach, over other approaches to architecture-independent programming such as the message passing libraries PVM or MPI lies in the simplicity of its interface. A piece of software written for an ordinary, sequential machine can be transformed to a parallel application with the addition of a bare minimum of instructions for parallel execution. Another advantage is the predictability of performance. The time required to execute a program can be computed from the program text and two parameters that characterise the target architecture. BSP cost analysis can therefore be used to guide algorithm development towards highly optimised solutions that are applicable across a wide range of architectures. Objectives of the One-Day Practical Course This practical one day course will introduce the world-wide BSP parallel programming library BSPlib to users interested in, or active in, parallel computing. A pre-requisite is a working knowledge of C or FORTRAN. The main objectives of the BSPlib Boot-Up day are to enable the participant to: get BSPlib (from the World Wide Web or supplied disk) and install it on a variety of machines; execute and profile the example programs (C, FORTRAN), and write parallel codes using BSPlib; derive a simple cost model, and use the BSPlib profiling tool to enable accurate prediction on parallel performance across all platforms. All participants will be supplied with a "start-up" kit including: detailed course notes; the BSPlib source; numerous example programs.
