Subject: APPSPACK, Software for Derivative-free Optimization

Announcing APPSPACK 4.0: serial or parallel, derivative-free
optimization software for solving nonlinear unconstrained and
bound-constrained optimization problems, with possibly noisy and
expensive objective functions.

APPSPACK implements asynchronous parallel pattern search, which uses a
pattern of search directions to drive the search and determine new trial
points for evaluation. APPSPACK is written in C++ and uses MPI for
parallelism. Using APPSPACK to solve optimization problems has the
following advantages:

* /Only/ function values are required for the optimization, so it
can be applied to a wide variety of problems. The user need simply
provide a program (written in any language such as Fortran, C,
C++, Perl, etc.) that can evaluate the objective function at a
given point.
* The target applications are simulation-based optimization problems
characterized by a small number of variables (i.e., n < 100) and
by expensive objective function evaluations (typically complex
simulations that take minutes or hours to run). The procedure for
evaluating the objective function does not need to be encapsulated
in a subroutine and can, in fact, be an entirely separate program.
* The code can be run in parallel on a cluster of computers, greatly
reducing the total solution time. Parallelism is achieved by
assigning the individual function evaluations to different
processors. The (optional) asynchronism enables better load
* The software is freely available under the terms of the GNU Lesser
General Public License.

Subject: SeDuMi, Optimization Package for MATLAB

We are glad to announce that the Advanced Optimization Laboratory at
McMaster University, Canada ( takes
over the maintenance and development of the SeDuMi package originally
created by Jos F. Sturm, who passed away in October, 2003.

The new SeDuMi website is at, it currently
contains a Downloads section with the latest SeDuMi releases,
documentation, testsets and related papers, FAQ and a user forum. Users
can provide feedback and share their opinion and success stories about
the software, request new features, report bugs, etc. at the forum.

Currently, SeDuMi works in Matlab environment on Windows and Unix/Linux
systems. Experimental Mac builds and instructions on how to compile
SeDuMi under Mac OS X are under development. Updates for Matlab 7 are
going to be released in the near future. The maintainers also plan to
provide Windows builds optimized for Pentium IV and Athlon processors.

New features are planned to be added based on user requests and recent

We hope to see you at the website,

Subject: Deal, Finite Element Library

Version 5.1 of the deal.II object-oriented finite element library has been
released. It is available from the deal.II home-page at

Version 5.1 offers a number of improvements over previous versions. In
particular, it contains a version of the sparse direct solver package UMFPack,
as well as corresponding interfaces to use it from within deal.II.

In addition to this, the most noteworthy changes are:
- Vectors and matrices built on top of PETSc objects are now completely
integrated. In particular, it is possible to build block vectors and
matrices with them.
- In 3d, Lagrange elements now implement hanging node constraints for all
polynomial orders, not only for the first few
- Several classes have been optimized to use algorithms with a better
complexity in terms of memory use or run time
- Support for DLLs on Microsoft Windows.

A comprehensive list of new features and fixed bugs can be found at

All main features of the previous versions have been continued and improved:
- Support for dimension-independent programming
- Extensive documentation and working example programs
- Locally refined grids
- A zoo of different finite elements
- Fast linear algebra
- Built-in support for symmetric multi-processing (SMP)
- Output for a variety of visualization platforms.

deal.II can be downloaded for free and is distributed under an Open
Source license.

Subject: New Version of RADAR5 for Stiff Delay Equations

The second version of the code RADAR5 for the numerical solution
of stiff delay differential equations is available at the address
The code is written in Fortran 90 and is based on the 3-stage
Radau IIA implicit Runge-Kutta method.
It is able to solve retarded differential-algebraic equations,
including neutral problems with vanishing or small delays.
The new version 2 of the code RADAR5 implements a new strategy -
peculiar to implicit schemes - allowing to detect automatically
and then to compute very accurately those breaking points which
have to be inserted into the mesh to guarantee the required
accuracy. Driver examples for nine problems are also available.

Comments and remarks are welcome.

very high ciphering speed. The efficiency of cryptographic
algorithms is a crucial issue nowadays, and the design of hardware
implementations is an important point for providing new solutions.

of the postdoc is to participate to the development of a FPGA-based
PC board prototype for digital signature. Together with the
development of an experimental platform for best software and
hardware solutions comparizon, the goal is to offer a complete
hardware demonstrator usable by any standard computer. Work
directions may concern FPGA programming, elaboration of test
programs, data communication and system aspects.

contribute to the improvement of the available arithmetic, at the
hardware level as well as at the software level, on computers,
processors, dedicated or embedded chips, etc. Reliability,
accuracy, and speed are major goals that drive our studies. We also
take into account other constraints such as power consumption,
certification using formal proof techniques or reliability of
numerical software. Target arithmetics are fixed or floating point

Near-wall structures in 3D turbulent boundary layers

A PhD student is required to work on a research council
funded project.

The work will involve the numerical simulation and modelling of
near-wall structures in a three-dimensional shear-driven
turbulent boundary layer. The student will be supervised Dr C.
Davies at the School of Mathematics, Cardiff University, but
there will also be opportunities to collaborate with a team of
researchers led by Prof. P.W. Carpenter at the School of
Engineering, University of Warwick.

A well-qualifed graduate with a good degree in Mathematics,
Engineering, Physical Science or Scientific Computing is sought.
Some knowledge of Fluid Dynamics is desirable, but this is not
essential. More important is an interest in using mathematically
sophisticated numerical methods to develop a fluid dynamics simulation
code. This code will be used by the student to study and theoretically analyse
the behaviour of turbulent boundary-layer disturbances.

The project is funded for three years and includes a tax-free
stipend plus payment of full fees for an EU national. There is
provision for the successful candidate to attend a week long
introductory Computational Fluid Dynamics course at the VKI in

To initiate an application please send a full CV (including
contact details for three referees), together with a brief
statement that addresses why you are interested in studying for
a PhD in Fluid Dynamics.

Please note that funding is ONLY available for a student who is
normally resident in the EU (and not just resident in the EU
solely for educational purposes).
