Focus of this conference will be the application of the Connection Machine to the solution of large scale computational problems in physics, in particular computational fluid dynamics, chemistry, and engineering. PROGRAM: Monday, September 12 9:00- 9:30 PARALLEL THINKING VS. SERIAL THINKING Jim Bailey Data Parallel computing methods compute thousands of answers at once. We have all been taught since elementary school to compute in ways that keep only one answer active at a time. The difference between the two styles of computing, and example applications that fit well with each, are reviewed. 9:30-10:15 THE CONNECTION MACHINE ARCHITECTURE Jim Bailey The Connection Machine system is a data parallel computing system with 65,536 processors, a high-speed communications router, floating-point hardware, the DataVault mass storage system, high resolution display, front-end, and base systems software. The role and characteristics of each of these subsystems is introduced. 10:15-10:30 BREAK 10:30-10:45 DATA PARALLEL LANGUAGES: GENERAL PRINCIPLES Guy Steele There are several fundamentals of good data parallel programming practice that are independent of the programming language used. These overall fundamentals are introduced. 10:45-11:30 DATA PARALLEL LANGUAGES: FORTRAN 8x Guy Steele Fortran 8x is the first industry standard data parallel programming language. The array extensions provide a direct way to compute on parallel data structures. The data parallel extensions of Fortran 8x are reviewed. Familiarity with Fortran 77 is assumed. 11:30-12:15 DATA PARALLEL LANGUAGES: C* Guy Steele The pointer structure of C makes it an ideal base for data parallel programming. C* extends the language, in a manner consistent with C++, to include parallel data structures. The C* language is reviewed. Familiarity with C is assumed. 12:15- 1:15 LUNCH 1:15- 2:15 SCIENTIFIC COMPUTING: BASE ALGORITHMS Wati Taylor A variety of data movement and reduction primitives underlie efficient data parallel programs. These underlying operations are reviewed. The role of the CM-2 Sequencer in optimizing the performance of these primitives is introduced. 2:15- 3:15 SCIENTIFIC COMPUTING: SOLVERS AND LATTICES John Richardson Solvers and lattice-based algorithms (such as finite differences) are pervasive in scientific computing. Examples of these routines on the CM-2 are reviewed. 3:15- 3:30 BREAK 3:30- 4:00 DETAILED PROGRAMMING EXAMPLE: WAVE SIMULATION John Richardson The acoustic wave equation is a simple example of a scientific simulation that operates on a lattice. A simple two-dimensional finite difference solution, coded in Fortran 8x, is introduced. Modifications to implement fourth dimension in space, and to implement a three-dimensional model are introduced. 4:00-5:00 SCIENTIFIC VISUALIZATION ON THE CM-2 James Salem A graphics environment for real time visualization of the results of numerical simulations of Computational Fluid Mechanics will be discussed. Within this environment the researcher may interactively perform real time flow visualization experiments. Ideas for the future will be introduced. Session will include demonstrations on the CM-2 by Jamie Sethian. 5:00 RECEPTION (hosted by Thinking Machines Corporation) Tuesday, September 13 8:30 - 8:35 Welcome 8:35 - 9:30 Interactive Scientific Visualization and Parallel Display Techniques James A.

Their solution requires new or improved algorithms, while the architectural constraints imposed by the need for high performance pose new difficulties in implementation. The research and applications community have responded to these needs with a number of advances in the solution of sparse problems. This conference will provide a forum for the presentation of the most significant achievements in meeting these new challenges. Theoretical algorithms, new applications and implementations for vector and parallel architectures will be presented. We expect to have contributions in all of the traditional areas of sparse linear algebra, linear equations, eigenvalue problems, and least squares problems, as well as recent developments in such areas as sparse control problems and sparse optimization. The conference is organized to promote interchange of new ideas between the developers, the users and the implementors of sparse matrix algorithms. We encourage the participation of users of sparse matrix algorithms in structural engineering, computational fluid dynamics, computational chemistry and other fields, as well as the participation of algorithm developers. FORMAT: The conference will be limited by the availability of hotel rooms to approximately 150 participants. There will be no invited speakers. Instead, 18 of the contributors will be chosen to give 45 minute presentations in non-parallel sessions over the three days of the conference. In addition, there will be opportunity in 12 informal workshops, scheduled in four periods, for the other contributors to present their accomplishments and to discuss with their colleagues the needs and directions for future work. All accepted abstracts, whether for formal or informal presentation, will be distributed in the conference program. DEADLINE FOR PAPERS: In keeping with the goal of presenting the most current advances, the deadline for submissions is not until Feb. 1, 1989. In selecting speakers, the committee will evaluate most positively novel and unpublished work. Promising work in progress is appropriate for submission. LOCATION: The Salishan Resort is a first-class resort in an attractive and secluded location on the beautiful Oregon Coast. Contrary to usual anti-tourism propaganda, the weather at Salishan in May is usually warm, sunny and dry. The resort provides easy walking access to the beach, and has a wide range of exercise facilities. Its location is ideal for exploring the Oregon Coast for those who may want to arrive earlier or stay after the meeting. Transportation from the Portland International Airport (approximately 90 miles) will be available at specified times. PROCEEDINGS: The SIAM Journal on Matrix Analysis will publish a partial proceedings in a specially designated issue(s), consisting of refereed contributions solicited from presentations at this conference.
