It is extremely sad for me to inform the community about the death of
Konrad Zuse. He died on Dec. 18 at the age of 85 in his home in Huenfeld
near Fulda.
For those of you, who do not yet know his name: on an international level,
Konrad Zuse was the creator of the first really working fully automated,
program-controlled and freely programmable computer using binary floating-point
arithmetic. It was operational in 1941. He built this machine in the living
room of his parents here in Berlin. Fortunately, as he used to state, the Nazi
regime did not recognize the importance of his invention. After the Second
World War Zuse started to design a rather future oriented programming language
called "Plankalkuel" (plan calculus), which in fact shows certain construction
principles of modern object oriented languages. He started a firm, the ZUSE KG,
which, however, was later bought by Siemens, but not recognized as the jewel
that it really was (Siemens transformed it into a production site, so that all
know-how people left.) Konrad Zuse is the patron of the ZIB, the
Konrad-Zuse-Zentrum fuer Informationstechnik Berlin. As president of this
Center I got to know Zuse personally quite well. I really admired his
extremely abstract views, a high rank mathematician as well as a high rank
engineer! A universal genius of the kind that is rare worldwide. The same
degree of abstraction is also visible in his paintings, which were his hobby
throughout his life and the main occupation during his late years. Zuse rather
late enjoyed international recognition, only recently the History of Computer
Science put him into the right place. The Washington Museum still does not
(yet?) show him in the gallery of the main inventors of the field. Want to

Just look up URL:http://www.zib-berlin.de/Prospect/zuse.html .

Do not hesitate to write me on the subject!

Subject: New Textbook in High-Performance Scientific Computing

It's finally done! The following textbook is supposed to be
available from MIT Press for next semester's courses:

An Introduction to High-Performance Scientific Computing
by Lloyd D. Fosdick, Elizabeth R. Jessup, Carolyn J. C. Schauble,
and Gitta Domik

The authors begin with a survey of scientific computing and then
provide a review of background (numerical analysis, IEEE arithmetic,
Unix, Fortran) and tools (elements of MATLAB, IDL, AVS). Next, full
coverage is given to scientific visualization and to the architectures
(scientific workstations and vector and parallel supercomputers) and
performance evaluation needed to solve large-scale problems. The
concluding section on applications includes three problems (molecular
dynamics, advection, and computerized tomography) that illustrate the
challenge of solving problems on a variety of computer architectures as
well as the suitability of a particular architecture to solving a
particular problem.

The ISBN number is 0-262-06181-3, and the purchase price is $50 (in the U.S.). The book, some lab materials, and syllabi are also available by anonymous ftp from cs.colorado.edu in the directory /pub/cs/HPSC. (Beware that you will use up a LOT of paper if you decide to grab and print the whole thing.)

All the current members of the IPS will keep their Zurich offices, but get new mail and email addresses: CSCS/SCSC [or SCSC] ETH-Zentrum, RZ name@scsc.ethz.ch CH-8092 Zurich This includes, in particular, the following numerical analysts: Armin Friedli friedli@scsc.ethz.ch Gabor G. Groh groh@scsc.ethz.ch Martin H. Gutknecht mhg@scsc.ethz.ch Urs von Matt vonmatt@scsc.ethz.ch Wesley P. Petersen wpp@scsc.ethz.ch Klaus J. Ressel kjr@scsc.ethz.ch Eric de Sturler sturler@scsc.ethz.ch Phone and fax numbers remain unchanged. The addresses of the Manno site, where some of us will take over additional responsibilities, are CSCS/SCSC [or CSCS] Via Cantonale name@cscs.ch CH-6928 Manno Along with the merger there goes a reorganization of the former CSCS. The new CSCS/SCSC will have only two sections, Services' (operating the computing resources, which include a NEC SX-3 and a NEC SX-4, and providing machine specific support) and `Scientific Projects and Support' (SPS). The new organization is headed by a new director Jean-Pierre Therre (formerly with Cray Research (Suisse)), along with Djordje Maric (Director of Services) and Martin Gutknecht (Scientific Director), who are responsible of the respective sections. While the IPS will loose its name, it will survive as an enlarged new section of the new CSCS/SCSC, and we will continue our research and consulting work in scientific computing. The new SPS section will have the following groups (and group leaders): - Advanced Numerical Algorithms (ANA) - M. Gutknecht - Computational Chemistry (CC) - H.P. L\"uthi - Data Analysis/Solid State Physics (DA/SSP) - D. W\"urtz - Computational Particle Physics (CPP) - P. de Forcrand - Software Technology (ST) - K.

Organizers: Jesse Barlow, The Pennsylvania State University Ivan Slapnicar, University of Split (local manager) Kresimir Veselic, Fernuniversitaet Hagen Tentative speakers: Beresford Parlett, University of California at Berkeley James Demmel, University of California at Berkeley Ilse Ipsen, North Carolina State University Hongyuan Zha, The Pennsylvania State University Zlatko Drmac, University of Colorado at Boulder Jesse Barlow, The Pennsylvania State University Ivan Slapnicar, University of Split Kresimir Veselic, Fernuniversitaet Hagen The main theme is the accuracy in the EVD or SVD computation or even in solving linear systems. We will stress this to be a workshop and not overload the program with too many speakers. We rather prefer to give more time per speaker. We will therefore have invited lectures (one or two) in the morning, while the afternoon will be reserved for contributed lectures, including those from junior people, as well as for less formal discussions and working groups. Possible general themes for discussion are: (i) how to turn recent results on accurate algorithms systematically into a good software, (ii) how to present them in a monograph, (iii) how to let them influence the teaching of numerical linear algebra, (iv) real world engineering problems. In order to keep the local costs as low as possible, we expect to have a number of single and double bedrooms in a comfortable student dormitory located by the sea at a walking distance from the city centre. Split is a picturesque city with population around 200,000 which in this decade celebrates 1700 years of urban settlement. It is located on the Croatian Adriatic coast, the beauty of which is proverbial with its hundreds of islands and still quite unpolluted nature. Neither Split nor its neighbourhood carry traces of the (we may now hope) definitely passed war in Croatia. Split is accessible by train (9 hours trip from Zagreb), by ship (one night by ferry from Rijeka, Pescara or Ancona), by car (6 hours from Zagreb, 8 hours from Trieste), and by plane. Split airport has daily connections to all world destinations. There are direct flights from Dusseldorf, Frankfurt, and Rome on some days. All other connections are via Zagreb by Croatian Airlines.

As a result, more and more time is spent writing and maintaining computer code, and less time is spent on the application itself. Object technology offers a way to break this cycle. Structuring applications as assemblages of software objects, rather than as monolithic programs, may pave the way for more efficient and complex applications by making software reusable, distributable, and modular. The annual OONSCI conference promotes the use of object technology for constructing numerical applications. OONSCI provides a forum for computer scientists and scientific programmers, in both academia and industry, to learn about issues related to object-oriented programming and discuss their experiences. SCOPE: Examples of appropriate topics include: * Experiences with object technology * Use of non-programming language specific objects - for example, CORBA or Visual Basic controls. * Object-oriented languages and environments * Object-oriented design * Reusable software objects * Performance issues related to object-oriented programming Application domain specific papers should focus on the object-oriented techniques used. Sample application domains of interest to OONSCI are as follows: * Image processing * Computer graphics * PDE solvers * Engineering * CAD SUBMISSIONS: Submissions should be prepared for an audience with diverse backgrounds who come from many disciplines, rather than specialists in a particular discipline. General knowledge of object-oriented terminology can be assumed. Proposals are being solicited for: 1) Papers 2) Survey papers 3) Tutorials 4) Panel Discussions 5) Posters SUBMISSION DEADLINES: December 15, 1995 [extended to January 15, 1996] * Tutorials January 15, 1996 [Abstracts only are due] * Papers * Survey papers * Panels * Posters For submission guidelines see http://www.cs.msstate.edu/oonsci96/submission/ FOR MORE INFORMATION: Complete and up-to-the-minute information about the conference can be found on the Web at http://www.cs.msstate.edu/oonsci96/ or contact Anthony Skjellum Internet: tony@cs.msstate.edu Department of Computer Science Phone: (601) 325-4524 Mississippi State University Phone: (601) 325-8435 Mississippi State, MS 39762 Fax: (601) 325-8997 ------------------------------ From: Adhemar Bultheel <Adhemar.Bultheel@cs.kuleuven.ac.be> Date: Wed, 20 Dec 1995 15:10:22 +0100 (MET) Subject: Congress on Computational and Applied Mathematics Seventh International Congress on COMPUTATIONAL AND APPLIED MATHEMATICS Katholieke Universiteit Leuven, Belgium July 21-26, 1996 Purpose: The Congress will concentrate on the analysis of computational techniques for solving real scientific problems.
