Subject: Scientific Software Days, Austin, Texas, May 2009

MAY 21 - 22, 2009

The Texas Advanced Computing Center, in association with the Jackson
School of Geosciences at The University of Texas at Austin, is pleased
to present the third annual "Scientific Software Days" event. The
purpose of the event is to increase communication among scientific
software users, vendors, and service providers.

Day 1, May 21: Short presentations and Keynote Address
There will presentations about various scientific software packages.
Victoria Stodden of the Berkman Center for Internet and Society will
present a keynote on the subject of "The Future of Computational
Science: Information Sharing and Responsibility".

Day 2, May 22: Tutorials
Two half day tutorials will be presented:
- Karl Schulz of Texas Advanced Computing Center will present a
survey of version control and data management (intermediate)

- Matt Knepley of Argonne National Laboratory will present an
Introduction to PETSc (advanced)

The opening day of the event will be devoted to short presentations
about available software packages and technologies. We would like to
invite you to present your work to the scientific computing community
on that day. Contributed presentations should focus on software and
its use in scientific computing. You may be the author of the
software, or simply an expert user; if you think it deserves broader
exposure, here is your platform. We are also interested in case
studies, especially discussions on how supercomputing enabled your
work, the challenges and benefits of the supercomputing environment,
scaling and validation issues, and other aspects of your strategies
that might be of broad interest. Presentations will be 30 minutes in
duration, of which at least 5 minutes should be left for questions. If
you are interested in participating, please send an email to:

There is no cost for attending, but spaces are limited. To register,

Subject: Asynchrony in the PGAS Programming Model, New York, Jun 2009

Call for Papers
Workshop on Asynchrony in the PGAS Programming Model
Co-located with ICS 2009
Yorktown Heights, NY
June 8, 2009

The new golden era of concurrency offers a diversity of concurrent
architectures to the application programmer -- clusters of symmetric
multiprocessors, heterogeneous accelerators (such as the Cell,
GPGPUs), large core-count integrated machines (such as the Blue Gene),
and multiple levels of parallelism (multithreaded multicores, such the
newer Power architectures, or distributed multiprocessors like the
Cray MTA).

The central programming challenge for these new architectures is to
develop a suitable and robust programming model. The Partitioned
Global Address Space (PGAS) model has attracted considerable attention
as such a programming model, particularly in the High Performance
Computing space. However, widespread acceptance and extension to newer
paradigms (e.g. to heteregeneous accelerators and irregular
application domains) has been hampered by a focus on homogoneous
execution contexts and the Single Program Multiple Data (SPMD)
threading model.

Several research groups have recently started to investigate
asynchronous execution in the PGAS model. Asynchronous execution is
the foundation for active message programming, and fine-grained
concurrency (e.g. Cilk-style fork-join, OpenMP style teams). It is
also the basis for data transfer between non-coherent memories (DMA),
remote atomic operations, and in general for techniques for
overlapping computation and communication. Finally, asynchronous
execution offers a simple model for spawning massive multi-threaded
kernel computations on accelerators such as GPUs.

Authors are invited to submit a 10 page paper for consideration for
the workshop. We invite papers on all aspects of the PGAS programming
model, with particular emphasis on handling asynchronous
(multi-threaded) execution (topics enumerated below).

SCOPE: The conference is an annual event aiming to bring together a
diverse group of people from both discrete and continuous
optimization, working on both theoretical and applied aspects. Our
target is to present a diverse set of exciting new developments from
different optimization areas while at the same time providing a
setting which will allow increased interaction among the
participants. We aim to bring together researchers from both the
theoretical and applied communities who do not usually have the chance
to interact in the framework of a medium-scale event.

MODELING COMPETITION: An optimization modeling competition, sponsored
by AIMMS is organized. Finalist will present their results at a
special session of MOPTA09. Problem released January 31, 2009.

CONTRIBUTED TALKS: Each accepted paper will be allotted a 25 minute
talk. Authors wishing to speak should submit an abstract via the

Subject: Summer School on Sparsity at RICAM, Aug/Sep 2009

I'm very glad to announce the Summer School on "Theoretical Foundations
and Numerical Methods for Sparse Recovery" which will be held at the
Johann Radon Institute for Computational and Applied Mathematics (RICAM),
Linz - Austria, on August 31 - September 4, 2009.
The School is addressed to graduate students and early stage researchers.

The Program of the School and Important Notices are briefly illustrated
below. More information and addresses can be found at the web-site

The poster of the School can be downloaded from



Sparsity has become a very important concept in recent years in applied
mathematics, especially in mathematical signal and image processing, in
the numerical treatment of PDEs as well as in inverse problems. The key
idea is that many types of functions and signals arising naturally in
these contexts can be described by only a small number of
significant degrees of freedom. Clearly, one should take advantage of this
feature in order to design very efficient ad hoc numerical solutions
based on a drastic dimensionality reduction. This intensive School aims at
describing the novel ideas that have emerged in sparse recovery with
emphasis on theoretical foundations and numerical methodologies.

Our lecturers and courses:

Antonin Chambolle (Centre de Mathematiques Appliquees, Ecole
Polytechnique, Paris - FRANCE)
Title of the course: Total variation and related functionals

Massimo Fornasier (RICAM, Oesterreichische Akademie der Wissenschaften,
Title of the course: Numerical methods for sparse recovery

Ronny Ramlau (Industrial Mathematics Institute, Johannes Kepler
Universitaet, Linz- AUSTRIA)
Title of the course: Sparsity in inverse problems

Subject: The Mouseholder QR, part 4 of 8

Robert Burns original:

Thy wee bit housie, too, in ruin!
Its silly wa's the win's are strewin!
An' naething, now, to big a new ane,
O' foggage green!
An' bleak December's winds ensuin,
Baith snell an' keen!

Modern English, non-poetic:

Your little house, also in ruin! Its silly walls the winds are scattering!
And nothing, now, to build a new one, of green stubble grown in winter.
And bleak December winds ensuing, both severe and sharp.

Matrix translation:

Thy wee Householder too, in ruin!
Its silly col's the Inf's are strewin!
An' naething, now, to big a new ane,
O' function Green's;
A bleak expansion's unconvergin'
By standard means!
