The meeting will comprise three one-week modules each of which can `stand alone' though it is hoped that many participants will stay for longer periods. SERC will contribute towards the subsistence costs of a limited number of participants each week. The meeting is open to all interested researchers, but only those currently employed in the UK will be eligible for SERC support. In each week there will be three five-lecture courses given by the invited instructors, additional activities organised by the local expert and a programme of current research seminars given by participants. The outline programme for the meeting is: Non-linear Partial Differential Equations (15-20 July) A. Quarteroni (Pavia) Spectral Methods R. Nochetto (Maryland) Finite element methods for free and moving boundary problems L.B. Wahlbin (Cornell) Finite element methods for evolution equations C. Elliott (Sussex) Local expert Dynamical Systems and Bifurcation (22-27 July) W.J. Beyn (Konstanz) Numerical methods for Dynamical Systems J. Sanz-Serna (Valladolid) Nonlinear Stability W.C. Rheinboldt (Pittsburg) Differential Equations on Manifolds A. Spence (Bath) Local Expert Multivariate Approximation (29 July - 3 August) C. Chui(Texas A&M) Multivariate Splines N. Dyn (Tel-Aviv) Computer-aided geometric design M. Powell (Cambridge) Radial basis functions J. Gregory (Brunel) Local expert The lectures will take place from Monday to Friday each week and there will be a substantial amount of time available for research and discussion with the assembled experts. The aim of the specialist courses is to enable people with initially only a nodding acquaintance with a topic to concentrate on it and end up feeling quite competent in it, thus broadening their research horizons. It is hoped that a participant with a good initial knowledge may be enabled to work on significant problems in the area. It is hoped that some University holiday flats will be available so that participants can combine the meeting with a family holiday on the edge of the Lake District and the Yorkshire Dales National Parks. Further details and application forms are available from Dr Will Light, Department of Mathematics, Lancaster University, Fylde College, Lancaster LA1 4YF, England.

Joseph So (Mathematics, U of Alberta. JOSO@UALTAMTS.bitnet). ------------------------------ From: Frank Stetzer Date: 24 Jan 90 22:36:20 GMT Subject: Lagrangian Dual Algorithm I was rummaging thru my (paper) files and I found an old but (to me) fascinating article from my grad school days: Donald Erlenkotter, "A Dual-Based Procedure for Uncapacitated Facility Location." _Operations Research_ V26 N6 (Nov-Dec 1978), pp992-1009. I have lost track of this line of research, which I believe we referred to as Lagrangian Duals. Does anyone have any more recent references to this technique, especially as applied to facility location problems? Email (preferably) or post. Many thanks.

This program, designed to prepare the computational leaders of tomorrow, provides talented undergraduate students with an opportunity to develop supercomputing skills while pursuing their own research using advanced computational tools. The students' faculty advisers are also given training and support as part of this program. Students and faculty receive hands-on instruction in the use of the CNSF supercomputer and the chance to interact with scientists in their fields of interest and to participate in the research atmosphere of a national supercomputing center. The Program Students and their advisers will participate in this program as teams, with one faculty adviser and one or two undergraduate students per team. Each team should propose a computational research project in any area of science, mathematics or engineering. The project should be based on the FORTRAN language, require the computational power of a supercomputer, and be of a scope suitable for the student(s) to complete in the following academic year. The program begins with a four-week short course for undergraduates, June 4 through 28, 1990, at Cornell. The students will be trained in advanced computing methods, with particular emphasis on parallelism and vectorization. Last year's program included numerical methods lectures in areas such as Cholesky Factorization, Finite Difference Methods, and Hyperbolic Equation Methods, and Science Applications, such as "Circulation in Ancient Continental Oceans" and "Convection with Magnetic Fields." Faculty advisers will join the students for the final two weeks of the short course, June 18 through 28. The faculty members will learn about new techniques and developments in supercomputing and will participate in sessions on using advanced technology in the undergraduate curriculum. Advisers and students will work together to refine the computational strategy, advance the research, and further develop the overall project plan. The program continues after participants return to their home institutions for the 1990-91 academic year. Students will carry out their research projects by May, 1991, under the direction of their faculty advisers. Each participant will be allocated ten service units on the IBM 3090-600E for the computational research. The CNSF will provide technical support for the duration of the project. Midterm and final reports will be required. Eligibility and Selection A review committee composed of scientists from the Cornell faculty and the CNSF staff will select approximately 15 teams to participate in the program. Criteria for selection will include the merit of the computational research and the academic credentials of the team members. Each team's home institution must grant academic credit to participating students, and provide network access to the CNSF or funding for dial-up access. There is no limit to the number of teams that may apply from one institution. Typical students will have completed the junior year of study, but any qualified student with a graduation date no earlier than December 1990 will be considered. Students must have completed coursework in linear algebra, and coursework or experience in FORTRAN. Applicants must be U.S. citizens or permanent residents. Special consideration will be given to applicants from four-year colleges with limited research facilities. Women, minorities, and disabled persons are strongly encouraged to apply. The Facilities Participants will have access to all CNSF resources, including two IBM 3090 multiprocessor supercomputers with 12 vector facilities, parallel processing, and extensive graphics facilities including specialized animation equipment. The operating system, VM/XA with CMS, allows each application to use up to a gigabyte of virtual memory. The FORTRAN compilers support both vector and parallel processing. Most CNSF facilities, including some of the graphics capabilities, are accessible through dial-ups and networks. Stipend and Logistical Details Students who are accepted and complete projects will receive a stipend of up to $2,000 plus a travel allowance. Faculty advisers will receive a stipend of $250 /week of institute participation. The program includes room and board for both students and faculty advisers in Cornell University dormitories. Students and faculty will have access to libraries and other resources on the Cornell campus. This program is sponsored by the National Science Foundation and is dependent on approval of funding through the Research Experiences for Undergraduates Program of that agency. How To Apply Applications must be received by March 23, 1990.

The goals of the new Summer Institute in Japan program are to increase Americans' acquaintance with Japanese research institutions, to promote the benefits of cooperative research with Japanese investigators, and to build relations between the U.S. and Japanese research communities. Those eligible are graduate students (U.S. citizens or nationals) who are enrolled at a U.S. institution in either a Ph.D. program (persons in M.D. programs are not eligible) or an engineering graduate program of which they have completed a year or more. The 25 graduate students selected for this internship will spend the summer participating in on-going research projects at Japanese government laboratories in Tsukuba Science City, about 60 km northeast of Tokyo. The interns will also receive intensive Japanese language training and, through lectures, discussions, and occasional field trips, compare U.S. and Japanese culture, science policy, and the current status of selected fields of science and engineering. Graduate students travelling to Japan as interns in the Summer Institute program will be in Japan for eight weeks from June 16 through August 7. In all, 36 Japanese government research institutions are potential hosts for the Summer in Japan interns. They include such well known laboratories as the Electrotechnical Laboratory, National Institute for Environmental Studies, Mechanical Engineering Laboratory, National Institute of Agrobiological Resources, University of Tsukuba, the National Laboratory of High-Energy Physics (KEK), the National Institute for Research in Inorganic Materials, and the Tsukuba Life Science Center of the Institute of Physical and Chemical Research (RIKEN). The application deadline for the Summer Institute in Japan program is March 1, 1990.

Kitchen Registrar ------------------------------ From: Philip Keenan Date: Fri, 26 Jan 90 09:09:59 CST Subject: Vector Version of Paranoia I am trying to diagnose floating point accuracy problems we are having in our new vectorizing machine. I have run "paranoia", which seems to be the standard test program for verifying IEEE standard behaviour in scalar floating point machines. However, my copy of paranoia does not vectorize, and our problems occur only in vectorized codes. Does anyone know of a vectorizing version of paranoia, or of some other program along the same lines, designed to carefully check floating point arithmetic on vector (or parallel) machines? Any program would be helpful, but I would especially be interested in knowing if there is a standard program, like paranoia is in the scalar case, which is generally accepted as canonical. Replies may be sent to: keenan@tartarus.uchicago.edu Thanks very much! -- Phil Keenan ------------------------------ From: Walter Gander Date: 27 Jan 90 11:38:27+0100 Subject: Translation of Schwarz Textbook Recommended The textbook on Numerical Analysis of H. R. Schwarz (University of Zuerich) has recently been translated from German to English (John Wiley, 1989). I'd like to recommend it to the na-community. It contains the chapters linear equations, linear programming, interpolation, approximation of functions, nonlinear equations, eigenvalue problems, method of least squares, numerical quadrature, ordinary differential equations and pde. The book is widely used in German speaking countries and is rooted in the tradition of Stiefel and Rutishauser. Walter Gander ------------------------------ From: George Cybenko Date: Sat, 27 Jan 90 15:38:25 CST Subject: Supercomputer Applications Newsletter Recently, I agreed to co-edit (with Dennis Duke of Florida State University) the quarterly newsletter of the IEEE Technical Committee on Supercomputer Applications. The newsletter is much like the SIGNUM newsletter in that typical issues contain some mix of technical short notes, discussions and meeting announcements. The Technical Committee focuses on supercomputer algorithms and performance related issues. Position papers, commentaries and benchmarking results are appropriate and will be considered for publication. The TC has about 600 members. If you have any material suitable for publication in the Newsletter, please let me know. I would prefer to handle submissions by email whenever possible. The next issue, the first that I am editing still has some space, so a prompt response may make it into the next issue.
