**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

balancing.

* 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 (http://www.cas.mcmaster.ca/~oplab) 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 http://sedumi.mcmaster.ca, 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

publications.

We hope to see you at the website,

Tamás Terlaky,

**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

http://www.dealii.org/

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

http://www.dealii.org/5.1.0/news/5.0.0-vs-5.1.0.html

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

http://www.unige.ch/math/folks/hairer

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.

The INRIA project Arenaire offers a 12 months postdoc position

starting as soon as possible.

Objectives

Last years have seen major investments in public-key cryptography

research. Indeed, new commercial cryptographic products rely on

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.

In collaboration with several other groups (ACI Securite

Informatique --- http://www-rocq.inria.fr/codes/OCAM), the objective

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.

A joint research project of the candidate may be around

cryptography, low-power hardware, or hardware for computer

arithmetic.

Arnaire project.

Arnaire is a project of 16 researchers which aims at elaborating

and consolidating knowledge in the field of computer arithmetic. We

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

format, interval arithmetic, finite fields arithmetic and multiple

precision.

Skills and application

Knowledge in hardware design, for instance using VHDL for FPGAs, and

in the domain of cryptographic algorithms will be appreciated.

Interested candidates should contact or send files directly to

{Arnaud.Tisserand, Gilles.Villard}@ens-lyon.fr as soon as possible.

Files must contain a cv, a brief description of research work and

recommendation letters.

PhD Studentship, Cardiff School of Mathematics

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

Brussels.

To initiate an application please send a full CV (including

contact details for three referees), together with a brief
