SIXTH PARALLEL CIRCUS

Courant Institute, New York, NY

The Sixth Parallel Circus will be held at the Courant

Institute of Mathematical Sciences, New York University, on

Friday and Saturday, Oct. 27-28, 1989. 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. If you are interested in attend-

ing or would like further information, please send e-mail to

greenbau@nyu.arpa or regular mail to

(Note: I will be out of town until Aug. 1, so responses to

inquiries will be sent then.)

Ken Mandelberg's request for Mathematica "courseware" prompts me to ask

the question "Why would anyone wish to use Mathematica for presenting a

Numerical Analysis course in preference say to MATLAB or to the new Kahaner,

Moler, Nash book?"

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.

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.
