Subject: Gene Golub, 1932 - 2007

Gene Golub, founder of the NA Digest, passed away today, Friday, November 16,
at the Stanford University Hospital. He was 75 years old.

Gene returned home to Stanford recently from a trip to Hong Kong. He was
planning to leave again Tuesday on another trip, this one to Zurich where the
ETH was to honor him with a special degree. Instead, Sunday night he went to
the emergency room because he was "feeling lousy". On Tuesday, he was found
to have AML, acute myelogenous leukemia, a form of cancer that affects the
white blood cells. This is a potentially curable disease and he was expecting
to begin chemotherapy today. But serious complications developed suddenly
over night.

I was able to see Gene for an hour last night and he was in reasonably good
spirits. Mike Saunders was trying to get Gene's laptop to use dial-up over
the hospital's phone system because Gene said he was a couple of days behind
on his email. I was planning to get a wireless card for his machine today.
None of us had any idea how suddenly the situation would worsen.

The Stanford iCME students have created a memorial blog at .

Our community has lost its foremost member. He was a valued colleague and
friend. Goodbye, Gene.

Subject: Gene Golub

Gene Golub died around 9AM this Friday morning
November 16, at the age of 75, after a sudden
turn for the worse in his health. His career
spanned almost the entire history of postwar
numerical analysis, to which he made seminal
contributions, among which are beautiful
algorithms that have proven to be of great
importance in matrix and statistical computations.
Not the least of his contributions is the legacy
of congeniality in gatherings both internationally
and at his beloved Stanford University. I can
see him in his office or home surrounded by
students and younger researchers and hear him
tell me that this interaction was what he cherished
most. Yet when living memory of him passes, the
algorithms he created will continue to be used,
probably indefinitely.

Subject: 60th Birthday of Numerical Analysis

This month is the 60th birthday of numerical
analysis. The use of mathematics to study
computerized numerical algorithms began with
the publication of a paper by von Neumann and
Goldstine in November, 1947. The paper is
the earliest archival documentation of the
efforts of several people to create an
intellectual infrastructure in support of
scientific computing on the powerful new
machines which, in 1947, were yet to be
built. I have prepared a lecture on the
fascinating history of scientific computing
up to and including these developments,
and the contributions of von Neumann to
them. My talk has been given at over a dozen
colleges and universities and is appropriate
for both specialized and general audiences.
I would be happy to repeat it at your

Subject: Question regarding parallel iterative sparse solver

Dear Colleagues,

I am searching for open source codes/programs of the parallel
iterative sparse solvers, which should be developed by Fortran and
MPI. Also, the solvers need to handle matrices in nonzero format
storage schemes such as CRS and CCS. Our high-performance computer is
based on Distributed Memory System, which is a key feature to be
considered as well.

Any help in pointing out links to the source codes is greatly appreciated.

Subject: Conference on The Legacy of John Crank, Jul 2008

Conference on the Legacy of John Crank
Developments in Time Dependent PDEs, Diffusion and Free Boundary Problems
10 - 11 July 2008 Brunel University, Uxbridge, England
Organisers: J. Ockendon, C.M Elliott and J.R. Whiteman

A two day conference will be held at Brunel University, Uxbridge, UK
to consider the influence that the work of John Crank has had on the
numerical solution of time dependent PDEs, on the modelling of
diffusive processes and on free boundary problems. The focus of the
meeting will be on the state-of-the-art of the subject and on future
developments and applications, including industrial applications.

John Crank (1915 - 2006) originally worked in industry on the
modelling and numerical solution of diffusion in polymers. In 1943,
working with Phyllis Nicolson on finite difference methods for the
time dependent heat equation, he proposed the Crank-Nicolson method
which has since been incorporated universally for the solving of time
dependent problems. John Crank died in October 2006 and the purpose
of this meeting is to consider the legacy that he left to the
numerical solution of partial differential equations and in particular
to consider future developments and applications in the field.

Subject: Graduate Assistantships in Computational Science at Florida State Univ

Florida State University
School of Computational Science

Graduate student assistantships available for Ph.D. and Master's
degree programs in Computational Science at Florida State University.

The School of Computational Science at Florida State University
offers innovative Ph.D. and Master's degree programs in Computational
Science. Graduate teaching and research assistantships are available
for qualified, motivated students who are interested in receiving
interdisciplinary training in computational science.

Over the last few decades, computations have joined theory and
experimentation to form the three pillars of scientific discovery and
technological design. Computational science can be viewed as residing
at the intersection of mathematics, computer science, statistics,
engineering, and the sciences. Examples of problems in Computational
Science that are common to these disciplines include algorithm
development and analysis, multiscale techniques, scientific
visualization, data mining, etc. Due to the interdisciplinary nature
of computational science, it is essential that a computational
scientist be trained in an interdisciplinary setting. The School of
Computational Science is uniquely positioned to offer such training
because it has a truly multidisciplinary faculty consisting of
chemists, biologists, computer scientists, engineers, geophysicists,
mathematicians, physicists, and statisticians, with an even broader
spectrum of disciplines to be represented in the future.

Many, if not most interdisciplinary degree programs, including those
in computational science, are jointly administered by several
departments. Florida State University has put the horse before the
cart: it first created an independent, interdisciplinary unit, the
School of Computational Science which then developed and implemented
truly interdisciplinary graduate degree programs in computational
science. All faculty, postdocs, and students associated with the
School of Computational Science have offices in the same building,
leading to a supportive, synergetic environment in which
interdisciplinary research and education in computational science is
not only supported, but is a way of life. For more information about
the School of Computational Science and its graduate degree programs,
please go to

Students enrolled in the Ph.D. program in Computational Science can
choose several areas of specialization. In addition to the major
track, which trains students interested in the mathematical and
computer science aspects of computational algorithms that can be
applied to a wide range of disciplines, we offer tracks in
atmospheric science, biochemistry, biological science, geological
science, materials science, and physics. Soon, we will add a track in
Validation and Verification. Students following these tracks gain
expertise in computational issues specifically related to the chosen
field. All students, however, will be involved in truly
interdisciplinary training and research.

At the Mater's level, the School of Computational Science offers M.S.
and Professional Science Master's (PSM) degree programs. The PSM is a
terminal Master's degree geared towards students interested in
employment in an industrial or laboratory setting.

The School of Computational Science maintains a large and diverse
computing infrastructure in support of research and education.
Available computing resources include supercomputers, a number of
clusters and computational servers, a laboratory for scientific
visualization, a bioinformatics server, and more. The Visualization
Laboratory provides high-powered visualization resources to the
University community for research, data analysis of large data
collections, and education.

Florida State University is a national graduate research university
which has built a reputation as a strong center for research in the
sciences. It is located in Tallahassee, FL which is situated in the
Florida panhandle and is near some of the most beautiful, uncrowded
beaches in the United States as well as other scenic wonders.

Applications are being accepted now for Fall 2008. Assistantships are
available for qualified individuals. Minorities and women are
especially encouraged to apply. Detailed instructions about the
application process can be found at
