Scott Morton was the requester, 1993 6 25 1557 [morton@shell.com] 6847 linpack / dgbsl We currently receive about 1200 requests a day through netlib in Tennessee. Netlib has changed in a number of ways over the past year. We have added an X window interface called Xnetlib. If you haven't tried xnetlib you can receive the source or executable for a number of workstations by anonymous ftp'ing to cs.utk.edu and cd'ing to pub/xnetlib then getting one of the following, xnetlib.shar.Z xnetlib.ds5000.Z xnetlib.hp9000.Z xnetlib.sun4.Z xnetlib.rs6000.Z. In addition, we have opened up the netlib machine in Tennessee to anonymous ftp (netlib2.cs.utk.edu) and have modified the rcp command on the netlib2.cs.utk.edu, so you can rcp from our machine to any machine on the Internet provided you know the name of the file you want, i.e., rcp anon@netlib2.cs.utk.edu:benchmark/performance performance will get you a postscript copy of the Linpack benchmark report. We are about to release a new version of Xnetlib which will include a conference database server and a performance server. We would like to get your feedback on what we have and your comments on what you would like to see in the future.

If you already have a copy, I am interested in your comments. I have a limited number of copies available for persons who want to adopt the textbook in their course. Current supplements are: 1. A printed MATLAB Programming Guidebook for Numerical Methods. 2. IBM-PC and Macintosh disks containing Matlab m-file programs which implement all the algorithms in the textbook. If you need a copy please let me know. Best Regards, John Mathews Prof. of Mathematics Calif. State Univ. Fullerton Fullerton, CA 92634 mathews@fullerton.edu ------------------------------ From: Frank Stenger Date: Sun, 27 Jun 1993 10:30:58 -0600 Subject: New Graduate Numerical Analysis Text I wish to announce the publication of my text, "Numerical Methods Based on Sinc and Analytic Functions", by Springer-Verlag (ISBN 0-387-94008-1). This text uses analytic function methods to derive the symbolic formulae based on sinc functions, their approximation properties and error, and the derivation of numerical algorithms based on these symbolic formulae for solving a large class of problems stemming from applications. For example, the DFT formula, which yields the well-known FFT procedure is one of the formulas of the class, but there are many others, such as new methods of interpolation, quadrature, the approximation of derivatives, the approximation of one and multidimensional indefinite or definite convolution integrals, the approximate solution of ordinary differential equations, and the approximation of Hilbert transforms, over arbitrary intervals or contours. Included also are new methods of solving elliptic, parabolic, and hyperbolic partial differential equations, new methods of solving linear and nonlinear Volterra, Fredholm, multidimensional, and Cauchy singular integral equations, and new methods of evaluating and inverting Laplace and Fourier transforms. For example, the complexity, i.e., the amount of work required to obtain an approximate solution of a partial differential equation in d dimensions to within a tolerance of E is usually of the order of {log(E)}**(2d+2). The methods excel for problems with end-point singularities, for problems over semi-infinite or infinite regions, or for boundary layer problems. -- Frank Stenger ------------------------------ From: David Watkins Date: Mon, 28 Jun 93 09:31:58 -0700 Subject: Change of Address for David Watkins Dear Colleagues, I have taken a leave of absence from Washington State University.

Multilevel algorithms are fast solvers used e.g. in numerical mathematics and lattice field theory simulations. If you have a WWW browser up and running, try going to http://info.desy.de:80/pub/www/projects/MG.html If you have no clue what WWW is, you can go over the Internet with telnet info.cern.ch which brings you to the WWW Home Page at CERN. You are now using the simple line mode browser. To move around the Web, enter the number given after an item. To go to the MultiGrid documents, enter go http://info.desy.de:80/pub/www/projects/MG.html If you don't have Telnet, send the message HELP to listserv@info.cern.ch for instructions how to retrieve documents. The complete announcement for the MultiGrid and other informational pages on WWW is available at ftp.desy.de [131.169.30.33] in files /pub/www/projects/Announce/*.txt 26/06/93 Marcus Speh ------------------------------ From: Ken Atkinson Date: Fri, 2 Jul 93 16:47:32 -0500 Subject: A Boundary Element Package for Integral Equations A Boundary Element Package for Solving Integral Equations on Surfaces in Space This is to announce the availability of a package of programs for solving boundary integral equations for Laplace's equation in three dimensions. The programs in the package can be categorized as doing one of the following tasks. (1) Create and refine triangulations of smooth and piecewise smooth surfaces in 3-space. (2) Perform interpolations and integrations over these triangulations, including approximating the surface itself by piecewise quadratic interpolation in the parametrization variables. (3) Numerical integration of surface integrals. (4) Solution of integral equations with smooth kernel functions, with the discretized linear systems solved by either Gaussian elimination or two-grid iteration. (4) Solution of boundary integral equations of the second kind for both the interior Dirichlet problem and the exterior Neumann problem. The discretized linear system is solved by either Gaussian elimination or two-grid iteration. (5) Solution of a nonlinear boundary integral equation which arises from solving Laplace's equation with nonlinear boundary conditions. The package is restricted to triangulations which are "quasi-uniform"; but a future release (under development) will allow for graded meshes when solving problems in which the solution is badly behaved at some points on the boundary. The package is written in Fortran 77. One of the main purposes of the package is to make it easier to carry out experimentation with numerical methods for solving boundary integral equations on smooth and piecewise smooth surfaces in 3-space. For example, our integral equation codes are all for integral equations of the second kind; but the package can easily be used to study integral equations of the first kind. We welcome suggestions on additions to the package or on any other aspect of the package. To obtain the package, use anonymous ftp to our departmental network. ftp math.uiowa.edu login: anonymous (follow directions) cd pub/atkinson/bie.package Under the further subdirectory "users-guide", a User's Guide is stored in three formats: dvi, postscript, and latex.

S. Lomdahl, P. Tamayo, N. Gronbech-Jensen, and D. M. Beazley of Los Alamos National Laboratory for "45 Gflops Molecular Dynamics on the Connection Machine 5". L. Long and M. Kamon of The Pennsylvania State University and D. Dahl, M. Bromley, R. Lordi, J. Myczkowski, and R. Shapiro of Thinking Machines Corporation for "A Deterministic Parallel Algorithm to Solve a Model Boltzmann Equation (BGK)". Robert Means, Bret Wallach, and David Busby of HNC, Inc. and Robert Lengel Jr. of Tracor Applied Sciences, Inc. for "Bispectrum Signal Processing on HNC's SIMD Numerical Array Processor (SNAP)." Gary Sabot, Skef Wholey, Jonas Berlin, and Paul Oppenheimer of Thinking Machines Corporation for "Parallel Execution of a Fortran 77 Weather Prediction Model". A large number of entries reported very high performance on Cray Research, Inc. C-90 processors. These entries were too close in overall quality for the judges to pick one so the fifth finalist chosen is Cray Research, Inc., the first time the a company has been so honored. Sara Graffunder, who coordinated many of the submissions, will represent Cray. Records were shattered in several areas. The 23 entries received for this year's competition nearly doubled the previous high. The performance reported was over 8 times the previous best, 2 entries exceeding 60 billion floating point operations per second (Gf/s). Even more impressive is the fact that 12 entries achieved sustained rates over 25% of the theoretical peak performance of the machines they ran on. Price/performance improved by almost 600% to 7.5 Gf/s/million dollars. The finalists have been invited to present their work at a special session to be held at Supercomputing '93 in November. ------------------------------ From: S.

Graduate Module Shape Optimization and Mutational Equations J.-P. Aubin, M. Delfour, L. Doyen & J.-P. Zolesio September 27 - October 1, 1993 INRIA-Sophia-Antipolis F-06565 VALBONNE CX This Graduate Module is devoted to Shape Optimization and Design one one hand, to Visual servoing and Mutational Equations on the other hand. Both topics involve concepts of derivatives of shape maps (associating vectors with subsets) and of set-valued maps (associating subsets with vectors). This allows us to optimize shapes and to design kinds of differential equations (called sf mutational equations) governing the evolution of shapes and their control (visual servoing). Graduate Module Differential Games J.-P. Aubin, P. Bernhard, H.~Frankowska & M. Quincampoix September 27 - October 1, 1993 INRIA-Sophia-Antipolis F-06565 VALBONNE CX This Graduate Module is devoted to Differential Games, in the framework of evolution problems controlled by several players. The choices of strategies would be made either by mini-maximising intertemporal criteria and/or by imposing power constraints on the states of the players. Both points of view allow to takcle the em target problems. ------------------------------ From: Benito Chen Date: Mon, 28 Jun 1993 12:25:35 -0600 Subject: Wyoming Numerical Analysis and Applications Day Wyoming Numerical Analysis and Applications Day The Department of Mathematics of the University of Wyoming is organizing the SECOND ANNUAL NUMERICAL ANALYSIS AND APPLICATIONS DAY.

Started in 1984, the title immediately gained an international readership offering news, original articles, benchmarks and technical evaluations. The content focuses, not only on the largest machines, but also on other high-performance systems and concepts, such as massively parallel processing and distributed computing. Articles are short, refereed, and edited to ensure top scientific quality and readability. In order to serve both authors and readers the publication time is kept to a minimum and the journal is covered by a number of abstracting services so ensuring a wide audience. The current short life-cycle time of computer products and the short time-to-publication of "Supercomputer" match very well. The journal is therefore a very viable vehicle for the latest benchmark results, early experiences with new systems, etc. In general the contents covers: News Topics - Architectures - Hardware and software developments; - (Government) policies; - Market developments; - Supercomputer center presentations. Contribution Topics - Benchmarks; - Applications of all kinds; - Languages; - Vector and parallel algorithms; - Adaptation of software packages. If you feel that you(r team) can contribute to one of those topics, please contact us at SONDSCM@HASARA11.BITNET or send your contribution directly to Supercomputer PO Box 4613 1009 AP Amsterdam The Netherlands Sincerely, Jaap Hollenberg (on behalf of the editorial team) ------------------------------ From: Paul Van Dooren Date: Thu, 1 Jul 93 16:27:48 CDT Subject: Allerton Conference on Communication, Control, and Computing 31st ANNUAL ALLERTON CONFERENCE ON COMMUNICATION, CONTROL, AND COMPUTING SEPTEMBER 29 - OCTOBER 1, 1993 The Thirty-first Annual Allerton Conference will be held September 29 - October 1, 1993 at Allerton House, the conference center of the University of Illinois.
