This is an informal gathering of researchers interested in parallel processing. The intention is to share recent research results in the area of parallel computing, especially numerical algorithms and applications and programming tools. Students are espe- cially welcome to attend. There is no formal proceedings for the meeting. Each participant may submit a title of a talk that she/he would be willing to give, and the order of speakers will be set just before the start of the meeting. Previous Circuses have been held at Yale, Cornell, IBM Kingston, Rutgers, and RPI. The Sixth Circus is being chaired by Gene Golub and Olof Widlund and organized by Anne Greenbaum. The Courant Institute is located at 251 Mercer Street, New York, NY. Buses/taxis are available from Kennedy, LaGuardia, or Newark airport, and train service is available from surrounding areas. Hotels in NY are EXPENSIVE, but room sharing is possible.

The advertisement follows. Please contact me if I can be of any help. A regular mail address would allow me to send extra information. Ian Sloan sloan@napier.maths.unsw.oz or na.isloan@na-net.stanford.edu UNIVERSITY OF NEW SOUTH WALES SYDNEY, AUSTRALIA PROFESSOR OF APPLIED MATHEMATICS Applications are invited for the Chair of Applied Mathematics which becomes vacant following the retirement of Professor V.T. Buchwald. The other Chair of Applied Mathematics is held by Professor R.H.J. Grimshaw, and a Personal Chair by Professor I.H. Sloan. Applicants should have a distinguished record of research and scholarship in a branch of applied mathematics, and the ability to provide academic leadership. The School of Mathematics is one of the largest in Australia, and has a record of excellence in research as well as a commitment to teach at all undergraduate and postgraduate levels. Withing the School, the Department of Applied Mathematics, with an academic staff of around 20, has active research groups in optimization, optimal control, systems theory, numerical analysis, computational mathematics, nonlinear dynamics, wave theory, fluid dynamics and physical oceanography. The Department encourages interaction with other disciplines and research activity involving applications.

It seems to me that both of the above alternatives are more suitable for such a course than Mathematica, which as far as I can tell has yet to be proven as a system worthy of such an enterprise. I would welcome a discussion of the merits of Mathematica and other such packages either in this forum or in the SIGNUM newsletter. Patrick Gaffney ------------------------------ From: George Cybenko <gc@s16.csrd.uiuc.edu> Date: Fri, 21 Jul 89 21:07:15 CDT Subject: 1989 Bell Award for Perfect Benchmarks Gordon Bell is sponsoring a new award for high performance scien- tific computing that consists of five categories. Contestants can compete in any number of the categories described below. 1989 Bell Award for Perfect Benchmark Rules Four of the five new award categories are based on the Per- fect Club benchmarks, 13 Fortran codes from a range of scientific and engineering applications, including fluid dynamics, signal processing, physical/chemical computation, and engineering design. The codes have been collected and ported to a number of computer systems by a group of applications experts from industry and academia. The $2,500 prize fund will be distributed appropriately, at the discretion of the judges, among the winning entries in the following five categories: (1) Sixteen or Fewer Processors: The measure is the fastest wall clock time (including I/O) for the entire Perfect suite on any computer system that contains no more than 16 proces- sors. The programs must be executed as a sequential job stream, i.e., only one of the benchmarks may be executing at any moment. "Computer system" includes distributed systems. There are no constraints on modifications that may be made to the codes to obtain the results as long as solutions are sufficiently close to solutions obtained by the benchmark codes. (2) More than 16 Processors: The measure is the same as in 1., except that the computer system has more than 16 processors and all processors must participate in the execution of each benchmark. (3) Perfect Suite Cost-effectiveness: The measure is the max- imum cost-effectiveness run of the Perfect suite where cost-effectiveness is defined as 1 divided by the product of running time and the cost, where running time is defined in 1., and cost is the list price of the computer system and software at the time of the run. This disqualifies noncom- mercial machines from competing, unless they are a combina- tion of commercially available computer systems. (4) Algorithms Cost-effectiveness: The measure is the maximum cost-effectiveness for the total running time of four algo- rithms (not whole benchmarks) chosen each year. The same rules apply here as in 3., except that the current list price is based on the minimum configuration required to run the algorithm. (Write to address below for more details for 1989.) (5) Perfect Subset: The measure is the minimal running time, defined as in 1., but with no restriction on the number of processors, for two codes to be selected annually from the Perfect suite. (Write to address below for more details for 1989.) Processor Definition The processor divisions in 1. and 2., although somewhat arbitrary, are intended to reflect the broad classes of extant parallel systems: current systems range from small numbers of powerful processors to large numbers of extremely simple proces- sors. The division at 16 would move to a larger number over time. The number of processors is defined as the number of simultaneous program execution streams, i.e., in effect the number of program counters in simultaneous operation. For example the Cray Y-MP in operation today has 8 processors and the number is projected to grow to 16 and 64 for the Cray 3 and 4. Similarly, the Thinking Machines Corp. CM2 has up to 4 processors each with 16K process- ing elements or is a uniprocessor with 64K processing elements. The Perfect Club Benchmark Applications The Perfect Club was formed with the purpose of developing and applying a scientific methodology for the performance evalua- tion of supercomputers. Club members were drawn from industry and academic sectors and an initial suite of 13 Fortran codes were designated as the "Perfect" Benchmark programs. These codes were selected because they solved fundamental problems across a variety of applications requiring supercomputing performance - fluid dynamics, signal processing, physical/chemical computations and engineering design. See [BCKK89] for more information about the Perfect Club codes. [BCKK89] Berry, M., Chen, D., Koss, P., Kuck, D., Lo, S., Pang, Y.
