Subject: Petaflop challenge
Do you want to win a FREE trip to SC07?
Computing in Science and Engineering magazine (http://computer.org/cise)
is sponsoring a contest based on a challenge from Francis Sullivan
(IDA Center for Computing Sciences):
"A lot of my working life has been spent arguing for more compute power
and explaining the wonderful things that will happen when a more powerful
machine is delivered. So far, nobody has called my bluff by saying, 'Okay,
you can have all the computing you want. Now, what are you going to do
with it?'
What would YOU compute?
Let's fantasize. Suppose you had available, at your desk, a petaflop
machine. Assume that power and cooling were somehow taken care of and that
you could get the full power of the machine by writing programs in a
flexible and expressive language, no heroics necessary."
Email your answer in the form of a 1,000-word essay to Jenny Stout
(jstout@computer.org), with the subject line "petaflop challenge," by 10
August 2007. The winner will receive a year's subscription to Computing in
Science & Engineering magazine (http://computer.org/cise) and will see
their entry published in the magazine's November/December 2007 issue.
SC07 will also cover the winner's travel costs to attend its conference in
Reno, Nevada, USA. SC07 is the international conference for
high-performance computing, networking, storage and analysis.

Subject: Looking for large-scale banded matrices to test fast FPGA solver
I know matrix collections is a recurrent topic in the Digest, so I'm
writing hoping that someone can point us in the right direction.
We are looking for one or several large-scale banded matrices used in
practice (preferably from CFD or aerospace, but matrices from other fields
would be useful too) to test Accelogic's latest narrowband linear equation
solver. Bands from 3 to 64, and matrix sizes from a few thousands to
hundreds of millions.
Any help would be greatly appreciated.
We could provide benchmark data (both speed and solution values) for your
matrices in return. When running on a single FPGA chip, this solver
recently demonstrated the performance of ScaLAPACK on a 240-node CPU
cluster (the baseline is a cluster of 240 Woodcrest CPUs). The technology
is the result of a multi-agency effort to leverage FPGA performance for
supercomputing applications, via innovative reconfigurable computing
algorithms. It is led by Accelogic, with sponsorship from NASA, DOE, and
the Air Force, among others. I'd be more than glad to provide additional
information to those interested.
Thanks,

Numerical analysis has known an enormous evolution since the introduction
of digital computers in the years 1950-1960. This symposium wants to
bring together lecturers who were at the origin of this evolution to
testify about their experiences, and attendants who are the current
users of numerical analysis or who are just interested in the roots of
this discipline.
The following lecturers accepted our invitation:
Gerard Alberts, Kendall Atkinson, Claude Brezinski, Philip Davis, Jack
Dongarra, Brian Ford, Rolf Jeltsch, James Lyness, Robert J. Plemmons,
Mike Powell, Gerhard Wanner, Alistair Watson.

Subject: Research Fellow in Parallel Scientific Computing (Leeds, UK)
This project builds upon existing collaboration between the School of
Computing and the Institute of Materials Research at Leeds in order to develop
a parallel 3-d implementation of phase-field models of the solidification of
dilute binary alloys. The primary challenges posed by these problems are their
severe nonlinearity combined with a high degree of stiffness, resulting from
substantial differences in thermal and solutal diffusion rates. Our prior work
in two dimensions has allowed us to develop an implicit adaptive solver that
uses a nonlinear multigrid scheme at each time step, and the aim of this
project is to develop a 3-d parallel version of this scheme.
The Research Fellow will work within the Scientific Computing group in the
School of Computing, and jointly with the Institute of Materials Research,
starting on October 1st 2007. Candidates should posess a PhD in Scientific
Computing, Numerical Analysis, Computational Materials Science, Computational
Physics, or a related subject. Candidates should also have existing expertise
in at least some of the following topics: parallel computing, phase-field
methods, multigrid methods, mesh adaptivity (and be able to demonstrate the
potential to quickly acquire expertise in the remainder).
The post is for a fixed period of eighteen months and is offered within
Research Grade 7 (£27,466 - £30,913 p.a.)
Further particulars are available from
http://www.comp.leeds.ac.uk/pkj/PF-fp.html
Closing date 27th July 2007.
