Domain decomposition refers to a class numerical methods for obtaining
solutions of scientific and engineering problems by combining solutions
to problems posed on physical subdomains, or, more generally, by
combining solutions to appropriately constructed subproblems. It has
become a subject of intense interest recently because of its
suitability for implementation on high-performance computer
architectures.  The aim of this conference, and of similar gatherings
in the series, is to bring together researchers with different
backgrounds working in this active area to discuss recent and
prospective advances and to promote interaction among applied
scientists, computer scientists, and numerical analysts.


The conference will feature invited lectures, selected contributed
papers and poster presentations.  Themes of the conference will range
from basic theoretical research to industrial applications related to
domain decomposition (DD) method, including:

        numerical analysis of DD methods
        block and substructuring methods
        multigrid and multilevel methods
        fictitious domain methods
        DD methods for high order and spectral methods
        DD methods for nonlinear and time dependent problems
        DD methods in computational fluid dynamics and structural mechanics
        graph decomposition
        general iterative and preconditioning methods
        parallel implementations
        software developments


The conference proceedings  will be published by the American
Mathematical Society in the series Contemporary Mathematics.  Refereed
papers from both invited and contributed talks may appear in the

Potential contributors should submit an abstract of no more than one
page by May 15, 1993 to the conference secretary at the address below.
The submission of the abstract through e-mail is preferred.  Plain TeX,
AMSTeX and LaTeX are all welcome and sample tex macros are available 
via anonymous ftp to ( in the 
directory pub/ddm7. Plain text (ASCII) files are also acceptable.
Submitted abstracts will be reviewed by the Scientific Committee of
the conference and authors will be notified by July 15, 1993.

Those who arrive early will be able to register at a reception on
Tuesday, October 26 at 6:30pm. Final registration will start at
8:00am on Wednesday, October 27. The conference will begin at 9:00am
Wednesday and will end on Saturday, October 30. The conference will be
held at the Keller Conference Center on Penn State's University Park
Campus in State College, Pennsylvania.
The campus is in the center of the state on Route 26 and 322, south of
Interstate 80. It is on the main eastwest route of both the Greyhound
and Fullington trailways bus lines. USAir Express and United Express
serve the State College/University Park Airport, located five miles
from the campus. Rental cars and limousine and taxi services between
the campus and the airport are available.


The early registration fee (before Sep. 27) is $175 ($50 for
students). The registration fee after Sep. 27 is $200 ($60 for
students). The fee covers the opening reception, instruction,
materials, conference proceedings, the conference banquet held Friday
evening at 7:00pm and break refreshments. It may be paid by check,
money order, VISA/MasterCard, or request to bill employer.

 A final performance report
The development of high performance parallel computers has made domain
decomposition and related methods one of the most important techniques
in modern scientific and engineering computation, and the aim of the
conference was to bring together the leading researchers, both
established and younger scientists, in this increasingly active and
highly interdisciplinary field to survey and review the current state
of research and to promote interaction between scientists with
different backgrounds.  The conference featured 27 invited speakers,
62 contributed talks and 15 poster presentations, with more than 150
participants (including mathematicians, engineers, physical
scientists, and computer scientists) from 18 different countries.
More than 20 graduate students and young researchers were able to
attend the conference thanks to the support from NSF.  This conference
was one of the best attended ones of the field in recent years and was
very carefully organized (for example, there was not even one single
cancellation for the numerous scheduled presentations).  A conference
proceedings has been published by American Mathematical Society and it
represents some of the most recent and most significant developments
in the field.
