Subject: ATLAS 3.2 Available

The ATLAS (Automatically Tuned Linear Algebra Software) group is
pleased to announce ATLAS 3.2. ATLAS provides a complete, high performance
implementation of the BLAS library, and a small subsection of the LAPACK
library. Highlights of what's new in this release include:
SMP support via posix threads for Level 3 BLAS
Addition of infrastructure for user contribution of kernels, thus allowing for:
- SSE support
- 3DNow! support
- Speedups on ev6x, ev5x, UltraSparcs, IA64, and PowerPC architectures

In addition, the associated developer release (ATLAS 3.3) possesses
support for Intel's SSE2, allowing for maximal DGEMM performance of around
2 Gflop/s on a 1.5Ghz Pentium 4 (SSE1 provides a roughly 4 Gflop/s peak
SGEMM on the same machine). Prebuilt archives are available for many architectures,
including well-tested version of the developer release. In particular,
SSE2-enabled Pentium 4 libraries are available for both Linux and Windows.

More ATLAS information, including FAQ, errata, downloads and developer
results, is available at the ATLAS homepage,

ATLAS is a software package that will automatically generate highly
optimized numerical kernels for our commodity processors. As the underlying
computing hardware doubles its speed every eighteen months, it often takes
more than a year for software to be optimized or "tuned" for performance
on a newly released CPU. Users tend to see only a fraction of the power
available from any new processor until it is well on the way to obsolescence.

Subject: Request for User Feedback on the NEOS Server

We are requesting user feedback with a description of the work that has
been done on the NEOS Server for Optimization with as much detail as possible.
We would like to know, for example, the solvers used.
We would also like to know of any suggestions for improvement.

With the release of Version 4 (, we are
beginning to plan for the next release. Your feedback is essential to
our planning, and for our reports to funding agencies.
You can see user feedback for Version 3 at

Please send your comments to,

Liz Dolan and Jorge More' for the NEOS Team.

The NEOS Server is a project of the Optimization Technology Center,
jointly managed by Argonne National Laboratory and Northwestern University.

Subject: Postdoctoral Position at University of Graz

OPTIMIZATION at the University of Graz, Austria.

Within the research Center on Control and Optimization at the
Department of Mathematics at the University of Graz a postdoctorial
position in Numerical and Applied mathematics is available.

The successfull candidate must have a strong background in numerical
analysis and differential equations. Additional experience in the areas of
Optimization and/or Navier Stokes equations and/or Inverse Problems
is desirable. Good working knowledge of the English language is essential.

We offer excellent working conditions in a lively research environment.
The duration of the first contract will depend on the qualifications of
the candidate. It is expected that the position will be available for up
to three years. Interested candidates are encouraged to send an application
with c.v. and publication list to Prof. Karl Kunisch, at one of the addresses
given below.
