APPENDIX A
STATEMENT OF TASK
The task of the committee, as originally conceived, is described in the
following excerpt from the Notice of Financial Assistance Award from the
U.S. Department of Energy and the Research Grant from the Office of
Naval Research to the National Academy of Sciences:
The committee will carry out Phase I of a study to define criteria
for the development and performance measurement of large-scale
computers for scientific and engineering applications. Phase I will
synthesize a collective judgment on the best study plan for the
substantive aspects of the supercomputer criteria question. (Phase
II will carry out the substantive study, provided that the plan
developed in Phase I appears promising.) The committee will perform
the following tasks:
1. Select important, computationally intensive problems related
to large-scale scientific and engineering applications to constitute
the subject matter of the study.
2. Examine the computational characteristics of these problems
together with the capabilities of existing and prospective
large-scale computers so as to develop a study plan that will assess
the prospects of improved criteria for large-scale computer
development and performance measurement, the nature of such
improvements, and the anticipated consequences of these improvements.
3. Document the results of Phase T
The committee will consist of approximately ten recognized experts in
the following areas: numerical processing, symbolic processing,
algorithm design, computer architecture, computational physics,
computational mechanics, and computer performance measurement.

During the course of the study, a different emphasis of the Phase I task
was recommended by the committee and accepted by the representatives of
the sponsors. In particular, Phase I undertook to describe the problem
of performance measurement in some depth and to point broadly to
desirable directions of inquiry. However it was believed that the
detailed definition of a research program to resolve the problem could
be done more productively by the supercomputer community itself than by
this, or any other, committee. Consequently no study plan is proposed
for Phase II. Instead a different need is seen--a forum to track,
assess, and disseminate progress, so that research results get promptly
translated into practice.
