SEYMOUR CRAY DIES 10.05.96
NEWSFLASH HPCwire
Colorado Springs, Colo. -- Seymour Cray, 70, died Saturday at 2:53 AM in
Penrose Hospital from injuries he sustained Sept. 23 as a result of a
multiple-car accident. A hospital spokesperson listed complications from
massive head injuries as the cause of death. Cray founded supercomputer-maker
Cray Research Inc in 1972.
A native of Chippewa Falls, Wis., Cray earned his bachelor's degree in
electrical engineering from the University of Minnesota in 1950. His
professional career began with UNIVAC I. In 1957, he was one of the founders
of Control Data Corp.
SEYMOUR CRAY: A PERSONAL ESSAY
by Norris Parker Smith, editor at large
October 5, 1996 -- Seymour Cray is supercomputing.
The present tense is appropriate, even though Seymour Cray died today. His
identification with the concept and industry that he shaped will endure.
His was a life of wonderful simplicity. Seymour Cray was dedicated to
clearly-formed, strongly-held opinions about the best way to make computers
that were far more powerful than any that had existed before.
The world is full of technologists with very good ideas. A much smaller
number have outstanding ideas -- and Seymour Cray certainly belongs in this
category.
Seymour Cray was exceptional, however, because he devoted the same
exceptional creative intelligence to the practical tasks of turning his ideas
into machines that worked.
Even more remarkable, he founded and guided a company that built and sold
those machines, transforming supercomputing from an esoteric specialty into
a significant sector within computing.
Inventors and entrepreneurs of this versatility -- and impact on the world
-- are rare. One recalls Edison, Alexander Graham Bell, Marconi, but then one
has to grope for additional names.
Seymour Cray belongs in the same class. Supercomputing may have a less
obvious impact on ordinary life than the mass-market industries created by
those other household names.
Yet, through its indispensability for many of the most advanced spheres of
science and engineering, the consequences of supercomputing as Seymour Cray
conceived it may be as widespread.
A DIFFERENT SORT OF ENTREPRENEUR
Many single-minded persons with extraordinary creativity and
entrepreneurial determination are difficult and sometimes not very likable
personalities.
Seymour Cray was different.
If his life had taken a different turn, if he had spent a conventional
career as a thoroughly competent engineer in some large enterprise, he would
still have been respected, admired, and trusted by hundreds, perhaps
thousands of people.
Because Seymour Cray was an exceptional man -- in dimensions that reach
far beyond technological skills or the ability to start and sustain a
successful company.
Graceful, in movement, thought, and in personal relations, Seymour Cray
was dignified, confident, even authoritative, but gentle and patient. He
spoke forcefully and persuasively, especially in face-to-face conversations,
but he also listened carefully.
These qualities explain the exceptional strength and persistence of the
widespread loyalty and respect of people who worked for decades with Seymour
Cray. He also had an unusual impact on those, like this reporter, who met
him only once, for a brief interview with other journalists.
VALUED PRIVACY
Seymour Cray became a famous man, but he did not respond to fame like most
other celebrities. He refused to be celebrated.
Many of the obituaries that will appear during the next few days will use
the word "reclusive." The writers may attach an implication that he was
eccentric, perhaps a bit weird.
That would be misleading. To be sure, he took little interest in marketing,
beyond the circle of personal friends whom he regarded as collaborators
rather than customers. He had the utmost faith in his products, and he was
confident that their excellence was sufficient eloquence.
He valued his privacy and had little taste for the penalty of fame in this
century -- which is to be forced to expose one's personal life and nature to
the world, through the often-distorting lenses and preconceptions of the news
media.
For those who knew Seymour Cray, he was a very normal man -- except for
his remarkable personal qualities as well as his originality.
RICH TESTAMENT
Time passed. In supercomputing, other ways to achieve exceptionally high
performance began to equal, and then to surpass, the architectural
philosophies that Seymour Cray believed in.
During the last few years, he endured repeated disappointments -- although,
characteristically, he launched a new venture only a few months before his
tragic and untimely death.
Nevertheless, his computational watchwords of simplicity, balance, and
efficient memory management remain as sound today as at the beginning of
Seymour Cray's lustrous career.
Many creative minds are contributing to the contemporary development of
supercomputing in a number of directions -- many of them distant from the
solutions that Seymour Cray originated.
Systems with performance in the hundreds of gigaflops are becoming
routine. Teraflop performance is now a realistic and imminent goal. Equally
important, products capable of several gigaflops are becoming available at
prices less than the pricetag on a well-equipped family sedan.
Yet all of those responsible for these modern marvels must acknowledge
that they are building upon the rich testament of an extraordinary man.
In death as in life, Seymour Cray is supercomputing.

I regret to inform you that Professor Thoger Busk of the Dept. for
Numerical Analysis, DTU, Lyngby, Denmark, passed away on Wednesday,
September 25, after a few months illness.
Thoger retired eight years ago from the chair of Numerical Analysis at
DTU and in later years spent time on his passion of collecting ancient
coins and medals of which he was compiling a register for the Danish
National Museum.
Thoger is survived by his wife, Mary, and their son John.
We will always remember him as a warm and humorous person who
made many friends the world over.

Subject: Orthogonal Matrices as a Product of Jacobi Rotations
Any SO(n) matrix can be written as the product of
n(n-1)/2 Jacobi rotations. As an example, a 3-dim
rotation matrix can be factored into three rotations
by Euler angles. By extension of this example, a set
of 2x2 rotations that generate a give SO(n) matrix
can easily be found.
Q: What is the oldest known solution(s) to this problem?
Is there a traditional attribution?
Is the problem treated in any generally available textbook
or journal?

Subject: Phone Numbers in France
Dear na.digest,
Starting October 18, all the phone numbers in France are going to change.
Even though most people use e-mail to communicate, I was thinking the
following information could be useful.
Starting Friday October 18, 1996, at 11pm, all the phone numbers in France
will change. We are switching from an 8-digit system to a 10-digit system.
Two new digits will be put in front of the old phone numbers depending in
which region the phone number is located. France will be divided in 5 zones.
To know in which zone a phone number is you just have to look at the 2 first
digits of the 8-digit old number and apply the following rules:
01: Paris and suburbs: 30,34,39,40-49,53,55,60,64,69
02: North-West: 31-33,35,37-41,43,47,48,51,54,96-99
03: North-East: 20-29,44,60,80-89
04: South-East: 42,50,67-79,90-95
05: South-West: 34,45,46,49,53,55-59,61-63,65
So, as an example, my office phone number that is now 45 95 65 39 in a suburb
of Paris will become 01 45 95 65 39.
BUT, be careful if you call from abroad you must not dial the 0 in front of
the number, so you just have to use a 9-digit number. To call me you will dial
33 1 45 95 65 39. Moreover, when you are in France and you want to place an
international call, you won't have to use the 19 as before but 00 as in all
civilzed countries.
Good luck

Subject: Global Optimization Software Review
Dear Colleagues:
At the INFORMS meeting in Atlanta (Nov 3-6, 1996), we are giving a tutorial
on global optimization (GO). In this context, we would also like to discuss
software you (may) have developed for solving global optimization problems.
This information will also be used in our forthcoming software review.
Approaches to solve continuous GO problems, as well as various combinatorial
optimization algorithms are of relevance for the review.
Please send us a summary description (no more than two pages), providing the
following information:
- name of the software (including version names, if appropriate)
- GO areas / problem types covered by the software
- the basic algorithmic approach used, mentioning enhancements
- hardware and software environment / platform(s)
- test results and/or 'real world' applications
(experience: problem sizes solved, difficulties?)
- availability and form of user instructions / manual
- availability of software demonstration product(s)
- availability and form of technical support
- public domain or commercial availability information
- addditional comments (as needed)
- contact addresses (postal, phone, fax, e-mail, WWW - as per your wish)
- most important related references (up to five)
Please follow - as much as possible, with modifications as needed - the
format of the software package descriptions in the book "Optimization
Software Guide" (by Jorge More and Stephen Wright, SIAM, 1994).
Please send to both of us this information by e-mail (preferably as a Latex
file, or ASCII, if necessary). Also, please pass along our information
request to interested colleagues - we would like to make the survey as
complete as possible.
We will mail the collected information (possibly in a summarized form) to
every contributor; your comments and suggestions will be most welcome.
Thank you very much for your cooperation.

Subject: Sparse, Symmetric Eigenvalue Problems
Hi,
I am a member of a group of three which, for the last three years, has been
researching parallel algorithms for the partial eigensolution of large sparse
symmetric matrices. We have recently developed explicit restart techniques for
the Lanczos algorithm some of which are very efficient when implemented on a
massively parallel machine such as the CM-200. One of the techniques seems to
cope very well with the computation of closely clustered eigenvalues.
We have already assessed the performance of this technique using test matrices
from the Harwell Boeing Collection of Sparse Matrices. However, we would like
to test the technique further using other matrices which arise in 'real world'
applications. Does any one have access to a large sparse symmetric matrix of
this type which has closely clustered eigenvalues, particularly at the upper
end of the spectrum?
If so, would it be possible for us to gain access to it, thereby enabling a
more detailed assessment of the performance of the technique to be carried out?
Many thanks in anticipation,
Regards,
Jim.

Subject: New Book on Interior Point Methods
New Book on Interior Point Methods
Interior Point Methods of Mathematical Programming
Tam\'as Terlaky (Ed.)
Kluwer Academic Publishers (September 1996)
ISBN 0-7923-4201-1
This book primarily intends to give an introduction to the theory of
Interior Point Methods (IPMs) in Mathematical Programming.
At the same time we try to give a quick overview of the
impact, of the extensions of IPMs to smooth nonlinear optimization
and to give an impression of the potentials of IPMs in solving
difficult practical problems.
The book is divided into three parts. Part I summarizes the basic
techniques, concepts and algorithmic variants for linear programming.
Part II is devoted to specially structured and smooth convex programming
problems, while Part III illustrates some application areas. The authors
of the different chapters are experts of the specific area and were
asked to give a relatively easy introductory survey.

Subject: Protein Folding Survey
I have written a big survey paper on protein folding.
Preprints are available at
http://solon.cma.univie.ac.at/~neum/papers.html#protein
An abstract is appended below.
Arnold Neumaier, Vienna
A. Neumaier, Molecular modeling of proteins and mathematical prediction
of protein structure, SIAM Rev., to appear.
This paper discusses the mathematical formulation of
and solution attempts for the so-called protein folding problem.
The static aspect is concerned with how to
predict the folded (native, tertiary) structure of a protein, given its
sequence of amino acids. The dynamic aspect asks about the possible
pathways to folding and unfolding, including the stability of the
folded protein.
>From a mathematical point of view, there are several main sides
to the static problem:
- the selection of an appropriate potential energy function;
- the parameter identification by fitting to experimental data; and
- the global optimization of the potential.
The dynamic problem entails, in addition, the solution of (because of
multiple time scales very stiff) ordinary or
stochastic differential equations (molecular dynamics simulation),
or (in case of constrained
molecular dynamics) of differential-algebraic equations.
A theme connecting the static and dynamic aspect is the determination
and formation of secondary structure motifs.
The present paper gives a self-contained introduction to the
necessary background from physics and chemistry and surveys some of
the literature. It also discusses the various mathematical problems
arising, some deficiencies of the current models and algorithms,
and possible (past and future) attacks to arrive at
solutions to the protein folding problem.

Subject: Gabor Digest
The Numerical Harmonic Analysis Group (NUHAG) is proud to announce
the "Gabor Digest"
http://tyche.mat.univie.ac.at/gabor
The Gabor Digest is a private initiative inspired by the success
of Wim Sweldens Wavelet Digest
(http://arabigo.math.scarolina.edu:80/~wavelet),
but not competing with it. It is supposed to be an informal platform
for the exchange of ideas related to Gabor analysis, Weyl-Heisenberg
frames and its applications. In addition it should be a central node
in the WWW for those seeking information in this area.
In the beginning we plan two different subjects:
(1) The Gabor Digest; is a mailing list sent out periodically
(about every month). It contains information about recent
contributions in theory of Gabor analysis and its
applications in signal and image processing, pattern
recognition, vision, time-frequency analysis etc.
Further the Gabor Digest provides information about upcoming
conferences, questions, publications, software and algorithms.
(2) The Gabor Archive; is a place to collect publications
and abstracts resp., concerning Gabor analysis and Weyl-Heisenberg
frames. At the moment only a few abstracts and papers are available,
but authors are encouraged to contribute published papers and preprints.
The Gabor archive contains only the abstracts, and optionally
links to ftp-sites where the papers can be received. If You do not
have the possibility to offer an ftp site where your paper can be found,
we are willing to store it at the Gabor Archive.

Subject: Trace Theorem
Dear colleagues,
In several textbooks the trace theorem for fractional Sobolev spaces
is dealt with. Basically the trace operator acts from
H^s (Omega) --> H^{s-1/2} (Gamma) if s > 1/2,
with Gamma being the boundary of Omega, and if some additional
assumptions on the domain Omega are satisfied.
However, I did not find a source that stated if the trace theorem is
valid for s = 1/2, or if it is not valid, or if it just can not be
proven. So I wonder if there is a (comparatively) simple counterexample
for s = 1/2, or if the trace theorem can be guaranteed under some more
restrictive assumptions.

Daresbury Laboratory, Warrington, UK
Vacancies exist at the Daresbury Laboratory for 2 HSO's to work
in the application of high performance parallel computing to problems
in engineering, in particular in the areas of Computational Fluid
Dynamics (CFD) and computational mechanics. The main purpose of
the work is to support university and industrial activities in
the area of computational engineering by:
* collaborative development of parallel implementations
of engineering applications targeted at high performance
computing systems;
* supporting the exploitation of high performance computing facilities
with these applications with on-site facilities including:
a 64 processor Intel iPSC/860; a 16 processor IBM SP2; and
clusters of HP and IBM workstations, and off-site facilities
include a 16 processor J90 and a 512 Cray T3D;
* disseminating information through workshops and newsletters
into the academic and industrial communities.
The post is in the Computational Engineering Group which has
parallel computing interests in: parallel mesh partitioning; parallel
mesh generation; dynamic load balancing; advanced turbulence modelling;
process engineering, parallel algorithms; and internal and external
flows for both compressible and incompressible flows. The Group has
a number of state-of-the-art workstations including Silicon Graphics
and DEC workstations and is an acknowledged centre of excellence in
parallel programming. The main duties of the post will be:
* to stimulate and assist in the development of leading edge parallel
applications in collaboration with industry and academe;
* to assist groups with the exploitation of high performance computing
facilities at Daresbury Laboratory and other national centres;
* to liaise with initiatives supporting related activities e.g. ERCIM,
ERCOFTAC;
* to disseminate information via appropriate mechanisms,
such as newsletters, workshops and meetings and to assist in organising
workshops on parallel computing and its exploitation within engineering.
The ideal candidates will have a degree and at least 2 years relevant
experience or a Ph.D. in an appropriate computational subject. The
candidates will play a key role in parallel algorithm development and
supporting the exploitation of parallel computing in high performance
engineering applications. A good knowledge of CFD or computational
mechanics is essential and the ability to work within a team on academic
and industrial projects is necessary. Substantial experience of original
code development in a high level language such as FORTRAN is necessary.
Experience in C or other advanced programming languages would be beneficial
and a willingness to learn and understand a variety of computing platforms
is essential.
