W. Morton <morton@na.oxford.ac.uk> Date: 21-NOV-1988 10:45:51 GMT Subject: Fourth Leslie Fox Prize Competition Fourth Leslie Fox Prize, September 4th, 1989 Call for Papers Entries are invited for the fourth Leslie Fox Prize competition. Any person who is less than 31 years old on January 1st, 1989, and has not already won a first prize is eligible. Each entry should consist of three copies of a paper, describing some of the candidate's research, that is suitable for a 40 minute lecture at a numerical analysis symposium. Whether or not the work has been published or accepted for publication is irrelevant, but no person may submit more than one paper. Unsuccessful candidates from previous competitions are encouraged to enter. The entries will be considered by an Adjudicating Committee, its members being K. W. Morton (Oxford University), J. C. Mason (Shrivenham), and N. K. Nichols (Reading University). Particular attention will be given to the originality and quality of each paper, and to the suitability of the material for a 40 minute talk to a general audience of numerical analysts. About five papers will be selected by the Committee for presentation at a symposium that will be held at the University of Cambridge on Monday, September 4th, 1989. Only the papers that are presented at the symposium will be eligible for awards but, subject to this restriction, the Adjudicating Committee may award any number of first and secondary prizes. Entries should reach Professor K. W. Morton (Oxford University Computing Laboratory, 8-11 Keble Road, Oxford OX1 3QD, England; e-mail address morton@na.oxford.ac.uk) not later than April 3rd, 1989. Each candidate should include a statement that his or her year of birth is not earlier than 1958, and should indicate whether he or she would be available to present his or her paper at the symposium. The Adjudicating Committee may allow a deputy to present a paper in a case of exceptional merit. The receipt of all entries will be acknowledged. It is unlikely that travel funds will be available to assist candidates who attend the symposium. Any questions on this notice should be addressed to a member of the Adjudicating Committee. ------------------------------ From: Chris Paige <chris@research.cs.mcgill.ca> Date: Mon, 21 Nov 88 11:43:12 EST Subject: Changes of Address for Chris Paige My office address in Montreal has changed to - Chris Paige McGill University School of Computer Science McConnell Engineering Building 3480 University Street Montreal, PQ Canada H3A 2A7 Phone 1-514-398-3742 Messages 1-514-398-7071(cs office) Fax 1-514-398-3883 CSNET address: chris@cs.mcgill.ca I will be on sabbatical in Australia from 25th November until 28th April 1989.

Tatalias <TATALIAS@A.ISI.EDU> Date: Tue 22 Nov 88 20:14:28-EST Subject: Effects of Finite Precision I am interested in the effects of finite precision on the finding of solutions to systems of equations having a large number of complex-valued unknowns. Any pointers to references, software ala ACM Algorithm 532, and the whereabouts of Webb Miller or Celia Wrathall would be appreciated. Kosmo D.

Tatalias <TATALIAS@A.ISI.EDU> Date: Wed 23 Nov 88 08:07:41-EST Subject: Connection Machine Benchmarks I would like to know how fast the Connection Machine can solve systems of linear equations. If you are beta testing the Thinking Machines Fortran 8X compiler, have you run the Dongarra LINPACK benchmarks ? I would also be interested in Paris or C* implementations of Gaussian elimination or Gauss-Jordan. Thinking Machines has not yet responded to my requests for such information. The only information I have obtained is slower than I expected, by a factor of 30. Kosmo D.

Engl <K310773%AEARN.BITNET@Forsythe.Stanford.EDU> Date: Thu, 24 Nov 88 15:49:52 EDT Subject: Position in Linz, Austria Tenured Position of a Full Professor for Symbolic Computation at the Johannes Kepler University in Linz (Austria) (Research Institute for Symbolic Computation) Applications are invited for a newly created tenured position of a full professor at the School of Technical Sciences, Johannes Kepler University in Linz, Austria. Candidates should have an outstanding research record in at least one of the main areas of symbolic computation (computer algebra, computer analysis, computational geometry, computational logic, automatic programming etc.), a commitment to excellence in graduate teaching, and the ability and willingness to combine, in their field of expertise, mathe- matical/algorithmic foundations with potential industrial applications (for example, expert systems, geometrical modeling, robot programming, scientific software). Teaching and supervising of students may also be in English. Candidates from foreign countries are explicitly encouraged. The School of Technical Sciences has installed an independent institute for symbolic computation (RISC-LINZ, Research Institute for Symbolic Computation) with an 8 member faculty under the direction of Prof. Bruno Buchberger. RISC-LINZ operates in close interaction with the Department of Computer Science (a twenty-six member faculty) and the Department of Mathematics (a twenty-two member faculty). At Johannes Kepler University, the symbolic computation effort is a part of and a major driving force for a planned expansion (by 10 full professor- ships) of the School of Technical Science in the direction of "mechatronics" (intelligent control of technical production) in close cooperation with Austrian industry. The new site of RISC-LINZ, a medevial castle 15 minutes from Linz, equipped with excellent computing facilities, combines the advantages of city life with the pleasures of a rural environment in one of the most beautiful landscapes and in the cultural heart of Austria and Europe. Applicants should send a resume (together with a few important publications representing the candidates research expertise) to the Dean of the School of Technical Sciences, Prof. Dr. Peter Weiss, Johannes Kepler University, A4040 Linz (Austria). (Telephone Austria (732) 2468-312.), by February 28, 1989. Further information can also be obtained form the Chairman of RISC-LINZ, Prof. Dr. Bruno Buchberger, Johannes Kepler University, A4040 Linz. (Tel: Austria (732) 2468-9219. Electronic mail: K313370@AEARN.bitnet.) On NA.Net, information can be obtained via Prof.Heinz W.
