**Subject: New Release of ATLAS**

I am pleased to announce the release of ATLAS 3.6.0, the new ATLAS stable.

The ATLAS (Automatically Tuned Linear Algebra Software) project is an

ongoing effort focusing on applying empirical techniques in order

to provide portable performance. At present, it provides C and Fortran77

interfaces to a portably efficient BLAS implementation, as well as a few

routines from LAPACK.

It's been two years since the last stable, so there have been a large number

of changes. I will provide a few highlights here, and you can examine the

ChangeLog for full details (the ChangeLog can be found on SourceFourge

download page or in ATLAS/doc/ChangeLog).

The first thing is, of course, speedups. ATLAS 3.6 is *much* faster than 3.4

for most common architectures. In particular, Opteron, Athlon-64, Itanium 2,

Pentium 4, Pentium 3, UltraSparc II/III are all significantly faster in 3.6

than they were under 3.4. To give a flavor of this speedup, I have posted

a few initial timings at:

http://math-atlas.sourceforge.net/timing/

ATLAS also supports arch defaults for several new architectures. In addition

to the machines mentioned above, ATLAS has defaults for IBM Power 4, and

you can also build ATLAS using Intel's compiler on most Intel platforms.

Another new feature in 3.6 is an improved SYRK/HERK implementation, with

associated Cholesky speedup.

For further details, see ATLAS's homepage on SourceForge:

http://math-atlas.sourceforge.net/

The tarfile may also be downloaded from ATLAS's netlib homepage:

Clint Whaley

The National Research Council Associateship Programs are accepting

applications for awards for postdoctoral research to be conducted in

residence at the National Institute of Standards and Technology (NIST)

in Gaithersburg, Maryland and Boulder, Colorado. Among the topic areas

of interest are applied mechanics, computational fluid dynamics,

computational biology, materials science, algorithm development for

modeling communication systems, image analysis, applied optimization,

combinatorial and discrete algorithms, mathematical software, scientific

data mining, and quantum information. For details see

http://math.nist.gov/mcsd/postdoc.html.

The deadline for applications is February 1. The NRC program at NIST

is restricted to US citizens.

**Subject: Postdoctoral Position at Simon Fraser University**

Postdoctoral Position in Applied and Industrial Mathematics

Simon Fraser University (Burnaby, British Columbia, Canada)

Applications are invited for a postdoctoral position in Applied and

Industrial Mathematics beginning September 1, 2004 (the start date is

negotiable). The position will be held within the "Mathematical

Modeling and Scientific Computing (MMSC)" project, which is part of the

Mathematics of Information Technology and Complex Systems (MITACS)

Network of Centres of Excellence. Information about the project can be

found at the MMSC website (http://www.math.ubc.ca/~wetton/mmsc/). The

salary is $45,000 (Canadian) plus benefits.

The successful candidate will have opportunities for collaboration with

researchers at both Simon Fraser University and the University of

British Columbia in nearby Vancouver. No teaching is required for this

position, although limited teaching duties could be arranged (with

stipend) if desired. The candidate will work half time on industrial

problems from the group's sponsor, Ballard Power Systems, a world leader

in hydrogen fuel cell technology. Depending on interest and skills,

there is also potential for involvement with the "Computational Fuel

Cell Dynamics Lab," a new tightly-integrated high performance computing

and visualization facility located at SFU.

This position is for one year with expected renewal for an additional

year and is subject to the availability of funds. Candidates must

possess a recent Ph.D. in Mathematics or a related discipline, and have

proven ability, or potential, for excellent research. Experience in

scientific computing and industrial mathematical modeling are definite

assets.

Applications should include: a cover letter, curriculum vitae, 2 or 3

selected preprints/reprints, and names and contact information for three

references. All application materials should be sent to:
