Subject: Chebfun v4.0 release

The Chebfun Team is delighted to announce the availability of
Chebfun Version 4.0 at our website

This release is freely available under a new BSD license and, in
addition to improved performance and reliability, offers many
new developments, including:

* A more powerful syntax for differential equations,
including piecewise smooth solutions
* A new graphical interface (chebgui) for boundary-value,
eigenvalue, and evolution DEs
* A large new collection of examples showing Chebfun in action

Version 4.0 also represents a big change in the organisational
structure of the project by moving to fully open-source framework
and encouraging contributions from new team members outside
of Oxford. For details of how to get involved, take a look at the
Developer Zone on our website.

Subject: Mini-Course on PDE-Constr Optim, Switzerland, May 2011

Mini-course on PDE-Constrained Optimization, University of Basel,
Switzerland; May 23-27, 2011

The Department of Mathematics and Computer Science of the University of
Basel will host a one week mini-course on PDE-Constrained Optimization.
The mini-course will be given Prof. Eldad Haber, University of British
Columbia, Canada.

The course is designed to present practical solutions for optimization
problems with partial differential equations as constraints. The course is
made of lectures and exercises that use realistic problems and, for some
cases, real data. Code will be written in Matlab.

There is no mini-course fee. Further information can be found at the

Marcus Grote and Olaf Schenk, University of Basel

The mini-course is supported by the SNF Pro*Doc program on "NumPDE on
Numerical Analysis and Scientific Computing"

Subject: Uncertainty Quantification in Sci Comp, Colorado, Aug 2011

The IFIP Working Conference Uncertainty Quantification in Scientific
Computing will be held August 1-4, 2011 in Boulder, Colorado, USA.

The purpose of the conference is to bring together research scientists
and policy-makers to assess our current ability to quantify uncertainty
in predictive modeling and simulation, to raise awareness of associated
challenges within the wider numerical software community, and to
envision a research agenda to advance progress in this critical area.

The conference will include some 24 invited talks, a panel discussion,
and an ad hoc "hot topics" session. Speaker slots are limited and at
this time most have been filled. However, the conference agenda provides
ample time for discussion among attendees.

Attendance is by invitation only. If you would like to participate,
please contact Andrew Dienstfrey ( or
Ron Boisvert ( with a statement of interest.

Program Committee: Andrew Dienstfrey (NIST, USA), Ronald F. Boisvert
(NIST, USA), Maurice Cox (National Physical Laboratory, UK), Bo Einarsson
(Link=F6ping University, Sweden, retired), Brian Ford (Numerical Algorithms
Group Ltd., UK, retired), James (Mac) Hyman (Tulane University, USA, SIAM
Rep), William L. Oberkampf (Sandia National Laboratories, USA, retired),
Tony O'Hagan (University of Sheffield, UK), Michael Oberguggenberger
(University of Innsbruck, Austria)

The conference is sponsored by the National Institute of Standards and
Technology (NIST) and the IFIP Working Group 2.5 on Numerical Software.
Additional financial support will be provided the DOE Office of
Advanced Scientific Computing Research.The meeting is being held in
cooperation with SIAM.

Subject: Seeking NAS benchmark specialist, 2 month consultant

Technology company is seeking for a specialist in the NAS benchmarks who
can provide high-level advice to the company (starting immediately until
mid-May). Someone who can help with code development on the
implementation of the benchmarks for different accelerated platforms, as
well as manage performance issues is preferred. You would work with system
developers on integration issues to implement the benchmarks and produce a
final report with the benchmark results.

If you want to come to Weston and have two months of fun in sunny Florida,
and you are a student and want to take this as a part time opportunity, or
just a general consultant, you are a fit candidate. It is also your choice
whether or not to work remotely. This opportunity would require at least
an initial visit (for kick-off) to headquarters in Weston, FL, if you
decide to work remotely.

The only requirement is to have immediate availability, and to commit to
the delivery of the results by the first week of May.

The pay will be highly competitive, including a special bonus based on
performance and timeliness, and commeasurable with experience and
potential impact of your work. There is the possibility of extending your
engagement with other projects as a consultant or even as a full-time

If you are interested, please send your CV and a quick email explaining
your specific experience working with NAS benchmarks.

Note: It is less important that you submit the perfect resume, and more
important that you apply as soon as possible.
