**Subject: Linux BLAS for Intel Architecture**

Linux BLAS are now available for Intel Pentium Pro and Pentium II

processors at http://www.cs.utk.edu/~ghenry/distrib. This html site will

act as a distribution mechanism for the work done on the Intel ASCI Option

Red Supercomputer at SNL that could be useful and easily ported to Linux-based

workstations. This will include the BLAS, FFTs, general utilities and

packages/libraries, and library support for Extended Precision Arithmetic.

This is not an "official Intel" release, hence it is not on an Intel web-site,

but the libraries there were built and tuned for the Intel architecture.

Please feel free to grab as much of this free software as you desire,

**Subject: Searching for PLOD Package**

I'm making an inquiry for a person outside my institution who apparently

doesn't have ready Internet access. He found a description of a program

called 'Plod' in IEEE Micro for August 1988 (title: 'Mathematical Software:

Plod'), and is looking for the code. It's described as a package for the

solution of systems of first order initial-value ODE's, using a simple

language for the description of a system, which is then translated to

Fortran code and solved with optional graphic output. (This sort of thing

has been done in commercial packages, of course, but he's looking for

something free, or so I believe). He sent me a copy of the article; it

doesn't say where to get the source but gives David Kahaner as a contact.

(He could even be reading this.) Before I pester Kahaner personally, I'd

like to try this list.

I did searches on 'plod' at <http://gams.cam.nist.gov/> and at

<http://www.netlib.org/>, with no luck. As I explained to the searcher, the

program may have evolved into something else in 10 years, or perhaps he

should search for software based on his problem description and not on a

specific package name. Still, if the package code is still available, it

might be useful for him as a starting point.

**Subject: Subsystem Modeling and Estimation**

Question: Literature on subsystem modeling/parameter estimation

Suppose you have a complex system consisting of interacting subsystems,

each with an approximate model depending on unknown parameters.

>From measurements at the whole system in different states, you wish

to obtain information to improve the component models qualitatively,

that is, find out which of the subsystem models are "good" or "poor"

and, if possible, get hints "how" the poor models should be modified.

The interactions are known accurately and the models are sufficiently

smooth to perform gradient-based parameter estimation (Gauss-Newton).

Reasonable "nominal" subsystem parameters are also known. Of course,

estimating the whole parameter set, then fixing the nominal parameters

of each subsystem and estimating the remaining ones, yields different

residuals and thus information on "good" or "poor". Also, the Lagrange

multipliers of the fixing conditions give local sensitivity information.

Does anybody know about theoretical or practical work on this issue,

or alternative approaches? Every hint is greatly welcome.

**Subject: Workshop on Object Oriented Methods for Scientific Computing**

SIAM Workshop on Object Oriented Methods for Inter-operable Scientific

and Engineering Computing

October 21-23, 1998

IBM Research

Yorktown Heights, New York

Background:

There is a growing awareness in the universities, and industrial

and governmental labs, that object oriented methods have the potential

for greatly improving the usefulness of computers in science and

engineering. There are already many efforts underway to redesign and

reimplement large codes that were written in the 70's and 80's to take

advantage of the improvement in maintainability and flexibility that

OO designs offer.

There still remains a large opportunity to improve the amount of reuse

within the community. Repositories such as Netlib and indices like

GAMS have improved our ability to share code, but making the shared

code useful requires widespread agreement about how the code is

structured and how scientific and engineering codes should

interoperate.

The world is changing. It used to be that large companies had their

own internal development teams, which implemented techniques from the

open literature or developed their own proprietary methods.

University researchers looked for methods for new classes of problems,

and pushed the limits of problem size. Software companies provided

application packages aimed at solving common problems, bundled

with everything from front-ends, to mesh generation and back-ends.

Now, as many large companies are cutting back on in-house software

development, universities and government labs seem to be doing increasingly

more software development and software vendors are springing up to provide

special purpose codes.

What are the new roles for academics, software companies, and industry?

Can a university department support a software product? How does a

company test and fire-harden research code? How can software

companies quickly incorporate new methods into a professional quality

product? Who owns what, and who supports what?

This interdisciplinary workshop will bring together representatives from

academia, software vendors, industry, and government labs, to identify

current and future challenges to implementing and using mathematical

algorithms in scientific and engineering computing.<p>

Organizing Committee:

Mike Henderson, IBM Research

Chris Anderson, UCLA

Steve Lyons, Mobil Technology Co.

Presentations:

The workshop will consist of 3 days of contributed and invited

presentations and discussions including, not not limited to, the

broad topics of:

The current state of the art.

- Tools that work together well (or poorly).

- The environments in which codes are used.

- How new techniques make their way to industrial use.

Developing interoperable scientific codes.

- Packaging codes.

- Balancing interoperability with performance.

- Maintenance and ownership of codes.

Future directions.

- Language of the future.

- Design techniques.

- Standards for the interoperation of mathematical software?

Case studies, position papers proposing topics for discussion, and

technical talks describing particular approaches are solicited.

The organizers are looking for a broad spectrum of participants,

including those involved in the development of industrial codes,

and industrial end users.

How to Contribute:

A report will be issued covering the workshop. Participants will be

required to submit a document for inclusion in this report.

Those wishing to participate should submit an abstract of a

case study, position paper or technical talk by July 1, 1998.

Abstracts should be sent to mhender@watson.ibm.com.

Notifications of acceptance will be sent by July 30, 1998.

Important Dates to Remember:

July 1, 1998, deadline for submission of extended abstract.

July 30, 1998, notification of acceptance.

August 31 1998, deadline for submission of final paper.

**Subject: Positions at University of Leicester**

Department of Mathematics and Computer Science

University of Leicester, UK

Recently, we posted details on NA-NET of 2 positions on Computer Science

available at Leicester. That posting consisted of the standard information

distributed about the positions. What was probably not clear from these details

was that (a) Leicester has a strong research group in numerical analysis, and

(b) there is already considerable collaboration between the computer science

and the numerical analysis research groups. One of the target areas for one

of the appointments is parallel computing.

I would encourage people who have a research interest in parallel computing

related to numerical analysis to consider applying. The lectureships are both

grade A/B on the UK scale: GBP 16,045 -- 27,985.

skills are also essential, with FORTRAN, IDL, Unix, and web skills

especially relevant. The candidate will work in a team environment

with other senior scientists, and will be expected to serve as a

principal inve stigator for research tasks, managing small groups of

other scientists and programmers. Good oral and written communication

skills are also required for frequent presentations of findings to peers.

**Subject: Positions at Chalmers, Goteborg, Sweden**

Applications are invited for several positions as

Associate professor ("universitetslektor") (Ref no 49/98)

At least two permanent positions as associate professor

("docent/universitetslektor") will be filled. The positions contain

undergraduate teaching at Chalmers University of Technology and

G=F6teborg University, research, supervision of doctoral students, and

administration. The proportion of research depends on the

availability of external research grants. At least one of the

positions is supposed to have a profile in numerical analysis and

scientific computing.

To be appointed you must have a PhD degree and proven pedagogical skills.

Our teaching is mainly in Swedish and the candidate should speak and

write Swedish or learn these facilities within half a year.

Assistant professor ("forskarassistent") (Ref no 51/98)

At least four positions as assistant professor will be filled. These

positions are limited to four years. There will be a large demand for

teachers also in the future and it is expected that the assistant

professors will have gained the competence required for the

appointment to a permanent position at the end of the four year

period.

By taking part in research and supervision of graduate students,

assistant professors are expected to develop their ability to

formulate research problems, lead projects, work in a resarch group,

and also to develop and prove their teaching skills. Applications

from young researchers with strong potential are favored. The

assistant professors will do half-time teaching and half-time

research.

To be appointed to a position as assistant professor you must have a

PhD and be a good teacher.

Application

The application should contain a short review in English of the

teaching experience and scientific work as well as other merits that

are referred to. Teaching and scientific records as well as other

merits that are considered most important should be indentified.

Teaching merits need to be verified. The complete application

including scientific publications should be prepared in three

identical packages.
