It is located at http://plato.la.asu.edu/bench.html and is really part of the webpage "Decision Tree for Optimization Software", http://plato.la.asu.edu/guide.html that Peter Spellucci and I are maintaining. Presently, there are two own benchmarks and one link: 1) Benchmark of some public domain interior point LP solvers comparing HOPDM, LIPSOL, LOQO, PCX 2) Benchmark of LANCELOT and SNOPT on the large CUTE testset 3) Results for PCx on a large number of platforms (netlib and other testproblems) Other benchmark results will be added in the near future. Comments are welcome as are suggestions for other benchmarks to be done or hints to existing results which could be added resp. be linked to. Hans D.

The referee reports and the reports from the members of the editorial board of "Reliable Computing" served as the basis for choosing the best paper. It was a difficult decision to make because we have received several excellent papers. We are pleased to announce the results. The 1996 best student paper award is awarded to the paper "Newton's constant of gravitation and verified numerical quadrature" by Oliver Holzmann, Bruno Lang, and Holger Schuett. This paper is published in "Reliable Computing", 1996, Vol. 2, No. 3, pp. 229-240. In addition to being a very good paper, it is devoted to an important application (measuring the gravitational constant) that has led to a good publicity for interval computations (in "Discover", one of the major popular science journals). Congratulations to Oliver Holtzmann, the student author of this paper, and thanks to all other students authors for their excellent job.

These algorithms allow for a fast, straightforward and accurate determination of linear multivariable models from measured input-output data. The theory of subspace identification algorithms is presented in detail. Several chapters are devoted to deterministic, stochastic and combined deterministic-stochastic subspace identification algorithms. For each case, the geometric properties are stated in a main 'subspace' Theorem. Relations between existing algorithms and literature are explored, as are the interconnections between different subspace algorithms. The subspace identification theory is linked to the theory of frequency weighted model reduction, which leads to new implementations and insights. The implementation of subspace identification algorithms is discussed in terms of the robust and computationally efficient RQ and singular value decompositions, which are well-established algorithms from numerical linear algebra. The algorithms are implemented in combination with a whole set of classical identification algorithms, processing and validation tools in Xmath's ISID, a commercially available graphical user interface toolbox. The basic subspace algorithms in the book are also implemented in a set of Matlab files accompanying the book. One application of ISID to an industrial glass tube manufacturing process is presented in detail, illustrating the power and user-friendliness of the subspace identification algorithms and of their implementation in ISID. The identified model allows for an optimal control of the process, leading to a significant enhancement of the production quality. The applicability of subspace identification algorithms in industry is further illustrated with the application of the Matlab files to ten practical problems. Since all necessary data and Matlab files are included, the reader can easily step through these applications, and thus get more insight in the algorithms. ------------------------------ From: Stefan Vandewalle Date: Mon, 21 Oct 1996 14:51:18 +0200 Subject: Domain Decomposition Course The Belgian Scientific Research Community `Advanced Numerical Methods for Mathematical Modelling' and the Belgian Interuniversity Pole of Attraction `Modelling, Simulation and Control of Complex Systems' organise a SHORT COURSE ON DOMAIN DECOMPOSITION METHODS 18 - 19 December, 1996 at the Katholieke Universiteit Leuven, Belgium The aim of the course is to introduce the basic ideas of domain decomposition, to provide insight in their mathematical background and to illustrate how they can be used in various application areas.

Butler Date: Fri, 25 Oct 1996 15:07:06 -0500 Subject: Supercomputing Program for Undergraduate Research Cornell Theory Center 1997 Supercomputing Program for Undregraduate Reserach (SPUR) JUNE 1 - AUGUST 1, 1997 This program offers undergraduate students the opportunity to pursue a computational science research project while developing skills in the use of high-performance computing technologies. Students apply to work on a specific research project under the guidance of a faculty or staff member at Cornell University. The proposed projects below explore current research problems in a diversity of areas, such as chemistry, solar convection, pollution control, fractals, and population modeling. Several of the projects include a strong visualization component. Successful applicants will attend, full time, a nine-week training and research program at Cornell University and will pursue the research projects using the high-performance computing resources of the Cornell Theory Center. Students will receive a stipend of $2,000, travel allowance, room (shared dorm room), and partial board (allowance at campus dining facilities). Applicants must be undergraduate students (graduating not before December, 1997) who are U.S. citizens or permanent residents. Students must have relevant coursework for their research areas, as well as coursework or programming experience in Fortran or C. Students who participated in previous SPURs are not eligible. Women, minorities, and persons with disabilities are strongly encouraged to apply. Students from four-year colleges with limited research facilities are also encouraged to apply. Applicants must submit a completed application form, two letters of recommendation, and college transcript(s). Applications must be received by February 28, 1997. Students will be notified of their acceptance no later than March 15.

It concerns Functional Languages in Numerical Analysis; a testcase and is a joint project between prof. O. Axelsson (Numerical Mathematics) and profs H. Barendregt and M.J. Plasmeijer (Informatics). The major purpose of the project is to provide evidence that parallel codes for large scale problems as arising in scientific computing can be efficiently implemented using functional languages. Specifically, when solving very large scale systems of equations such as occur for the Helmholtz equation in 2D and 3D for several frequencies of the irradiating waves used in ultrasound tomography, for instance, there is a need to develop new and faster algorithms, which can give an accurate answer in real time during the examination of the object (such as a human body). To this end parallel computing must be used with scalable algorithms. A new class of additive preconditioning multilevel iteration methods will be developed and compared with previous multiplicative type of methods. To simplify the programming and to optimize the code for a parallel environment, existing functional languages will be further developed and used in an interactive way with program transformation techniques for the iteration solution code. Such a mode of working requires intensive collaboration from teams from both mathematics and computer science. For this, the required supervising personnel as well as hardware, is available locally. For this position we are searching for a candidate who has finished or will finish shortly his/her university studies in numerical mathematics or in informatics and who is at most 26 years of age. The project requires someone who has extensive knowledge of numerical mathematics, who has excellent university marks (''cum laude'') and who has a documented interest for computer science and parallel algorithms. Appointment will be in temporary service with NWO, the Netherlands Organization for Scientific Research, for at most four years. Salary will be Dfl. 2.144 in the first year, rising to Dfl. 3.775 in the fourth year. Women and candidates coming from one of the member states of the European Union are particularly asked to apply. Anyone interested in this position who fulfills the above requirements is requested to apply, preferably via e-mail, to Owe Axelsson before November 11, 1996. email: axelsson@sci.kun.nl Adress: O. Axelsson, Faculty of Mathematics and Informatics, Toernooiveld 1, 6525 ED, Nijmegen, The Netherlands. ------------------------------ From: Mayer Humi Date: Mon, 21 Oct 1996 15:11:50 -0400 (EDT) Subject: Position at Worcester Polytechnic Institute MATHEMATICAL SCIENCES DEPARTMENT HEAD Worcester Polytechnic Institute (WPI) is an innovative technological university in engineering, science, management, humanities, arts and social sciences with an enrollment of 2,500 undergraduate and 400 full-time graduate students, located in central Massachusetts.
