Subject: 1992 Chauvenet Prize for David Bailey

I am very pleased to announce that the 1992 Chauvenet Prize has been awarded
to my colleague David H. Bailey of NASA Ames Research Center. The prize is
awarded annually by the Mathematical Association of America for a noteworthy
or expository survey paper. David received the prize for the paper
"Ramanujan, modular equations, and approximations to pi or how to compute
one million digits of pi". This is a joint paper with J. M. Borwein and P. B.
Borwein, which appeared in the American Mathematical Monthly, Volume 96, 1989,
pages 201 - 219.

The prize committee has described the accomplishment of the paper as follows:
"The article draws the reader into a delightful look at several areas of
mathematics. There is even an intersting comment on how computation of the
digits of pi is used to test the 'global integrity' of new supercomputers.
Anyone interested in the remarkable insights presented by Ramanujan, details
of numerical computation, use of deep results in modern mathematics to
tackle ancient problems, or simply the developments related to an easily
stated but largely open ended problem, will benefit from reading this article.
The sheer joy of mathematics shines clearly throughout the paper."

Readers of NA-digest may be interested to know that previous recipients
of the Chauvenet Prize include Steve Smale (1988), Jim Wilkinson (1987),
Gilbert Strang (1977), and Cornelius Lanczos (1960), as well as a long list
of distinguished researchers in other areas of mathematics.

Congratulations David!

Subject: Assistant Professorships ETH Zuerich

In NA-Digest Vol. 92 Issue 48 one, possibly two, Assistant Professorships
were announced. These positions are highly competitive since
competition is in all fields of mathematics. However ETH Zuerich is
planning the installation of a parallel supercomputer in 1993.
Hence the department of mathematics also welcomes strong
candidates from the area of

scientific numerical computing on parallel computers.

The official deadline for applications is January 31, 1993. However
applications which are only marginally late, 2-3 weeks say, will still
be considered.

Duties of the new professor include research as well as an active partici-
pation in undergraduate and graduate courses for students of mathematics,
natural sciences and engineering.

Candidates should have a university degree and succesfully completed own
research work. Willingness to teach at all university levels and to cooperate
with colleagues is expected.

The positions of assistant professors have been established to promote the
career of younger scientists. They are available for three years in the first
instance, with the possibility of renewal for additional three years.

Applications with curriculum vitae and a list of publications should be
submitted no later than JANUARY 31, 1993, to the President of the ETH Zurich,
Prof. Dr. J. Nuesch, ETH Zentrum, CH-8092 Zurich. The ETHZ specifically

Subject: Postdoc Position at Maryland/NIH

Maryland/NIH Postdoc

The Computer Science Department at the University of Maryland and
the Division of Computer Research and Technology at the National
Institutes of Health seek a postdoctoral researcher to work with
us to carry out applications driven computational science
research. The research will be motivated by leading edge biomed-
ical applications of interest to the National Institutes of
Health. We seek a researcher with an excellent research back-
ground in compilers, tools or algorithms for high performance
computers. The researcher should also have an intrinsic interest
in tackling challenging biomedical applications. This is a joint
position with both the Computer Science Department at the Univer-
sity of Maryland and the National Institutes of Health.

The postdoc's work will be applications driven; the key will be
to focus on what are likely to be the major applications classes
applicable to emerging problems in computational biology and com-
putational medicine. The aim of this work will be to take into
account the requirements posed by problems in computational
biomedicine in our ongoing efforts to address the closely related
systems software goals of:

developing methods to ease the burden of coding multiproces-
sor machines,

developing methods to produce and support codes that can be
easily ported between architectures,

providing tools for performance tuning and monitoring,
along with tools to predict how programs will perform on new

developing techniques for partitioning computational work
between a parallel machine's processors, along with methods
for mapping or dynamically remapping data into the machine's
memory hierarchy,

developing visualization methods needed to allow users to:

interpret their computational results, and

give programmers information needed to optimize the
performance of their programs.

The intent is for the researcher to work in close collaboration
with the research group lead by Joel Saltz in the Computer Sci-
ence Department at the University of Maryland and the group lead
by Robert Martino of the Division of Computer Research and Tech-
nology at the National Institutes of Health.

Subject: Grand Challenge Applications Groups


Fiscal Year 1993
Program Announcement

A Component of the U.S. High Performance Computing and Communications Program


The National Science Foundation (NSF) announces opportunities for
group oriented research for Fiscal Year 1993 in connection with the U.S.
High Performance Computing and Communications (HPCC) Program. Six to eight
proposals are expected to receive funding as Grand Challenge Application
Groups as a result of the opportunities described in this announcement.
Seven awards were made under this activity in Fiscal Year 1992.

Activities supported under this announcement are expected to achieve
significant progress on (1) fundamental problems in science and engineering
whose solution could be advanced by applying high performance computing
techniques and resources, and (2) enabling technologies which facilitate
those advances. In addition, it is anticipated that these activities will
generate significant new research in mathematics, computer science,
engineering and other scientific disciplines. This HPCC activity will
provide funding for multidisciplinary groups of scientists, engineers,
mathematicians and computer scientists to apply emerging high performance
computing and communications systems to advance the solution of diverse
science and engineering problems. The emphasis will be on support for
groups requiring HPCC capabilities, where such focused, cross disciplinary
support is generally unavailable or difficult to obtain. Any area of
science and engineering supported by NSF is eligible for funding under this

Proposers interested in submitting a formal proposal must submit 12 copies
of a preproposal by March 15, 1993.

The deadline for receipt of proposals is June 16, 1993.

The full text of this announcement is available on STIS as document 93-10.
It may be obtained by e-mail by sending a message to (or
BITNET: stisserv@NSF) with the text of the message:
