NATO ADVANCED STUDY INSTITUTE

Numerical Linear Algebra, Digital Signal Processing and
Parallel Processing


August 1 -12 Leuven , Belgium



The Advanced Study Institute (ASI) is intended to gather experts from
*numerical linear algebra
*digital signal processing
*parallel algorithms
and focus on the interconnections between these fields in order to
spark new trends and ideas in an area of growing interaction.
Tutorials in each of the major areas as well as "state of the art"
lectures will be given.

The ASI will be held over a two week period to allow ample time for
lectures, discussions and interactions. All attendees are expected to
stay during the entire period.

Modest but convenient housing will be arranged at the Groot Begijnhof
( a restored 17th century beguinage with modern conveniences) and at
the student housing park. There are sports facilities, nice walks in
the park and proximity to the city of Leuven. The climate is
temperate.

LECTURERS include:
Bellanger, Bitmead, Bjorck, Brent, Dongarra, Genin, Golub, Hammarling,
Ipsen, Kailath, Luk, McWhirter, Sorensen, Vandewalle, Van Dooren.

THINKING MACHINES CORPORATION

Research and Development
in Parallel Computational Methods and Scientific Software


Thinking Machines Corporation designed and manufactures the Connection
Machine, the first commercially available data parallel computer with
a performance of several Gflops for a variety of applications and a
capacity in excess of 10 Gflops for kernel functions. The
Computational and Mathematical Sciences group has immediate openings
for well qualified individuals with backgrounds in computer science,
applied mathematics, numerical analysis, optimization, computational
physics, fluid mechanics and solid mechanics. Positions are available
for systems programmers, application programmers, and scientists.
Immediate research and development tasks range from architecture,
language, and compiler related issues of particular importance for the
computational sciences to numerical methods, scientific subroutine
libraries, and application codes. Longer term research is directed
towards representations, modeling, algorithm design, and new methods
for computationally intensive problems in science and engineering.

The innovative architecture of the Connection Machine and its
supercomputer performance stimulates frequent interactions with
customers and leading scientists. Thinking Machines Corporation is
committed to being a leading force in computing and maintaining a
highly qualified staff of designers, programmers, and scientists.

Thinking Machines Corporation is an equal opportunity employer.

Interested applicants should send a resume in confidence to, or call:

Subject: Applied Math Position at West Virginia U.

-

- West Virginia University
Eberly Family Distinguished
Professorship
in Applied Mathematics


- The Department of Mathematics invites applications and
nominations for the Eberly Family Distinguished Professorship in
Applied Mathematics.

The holder of the Eberly Professorship will provide academic
leadership in the department's applied mathematics program. The
successful candidate must have outstanding scholarly
accomplishments in applied mathematics, a record of funded
research and a commitment to excellence in teaching.

The department has made several junior level appointments in
applied mathematics in recent years. Our research areas are in
applied analysis, approximation theory, continuum mechanics,
discrete mathematics, multi-phase flow, numerical analysis, and
perturbation methods.

WVU is located in Morgantown. It takes approximately 80
minutes to drive north to Pittsburgh and three and a half hours to
drive west to Washington DC. The Morgantown area has a population
of around 50,000 and the University has around 19,000 students.
The surrounding countryside is beautiful and offers a great deal
all year round. There are many hiking routes and skiing
opportunities within 20 minutes of town. The area is relatively
inexpensive and the selection of houses available is varied. A
typical three bedroom house costs in the region of $80,000. Annual
property taxes on such a house would be about $300. There are few
traffic problems in town.

Applications, nominations, or requests for information should
be directed to:

Dr Alphonse Baartmans
Department of Mathematics
West Virginia University
Morgantown, WV 26506

Enquiries by electronic mail can be sent to:

[email protected]
[email protected]

The deadline for applications and nominations is January 15,
1988. The position will be available August 16, 1988. Candidates
should submit a letter of application, a current vita and the
names and addresses of five references. WVU is an Affirmative
Action/Equal Opportunity employer.
