Workshop on Unstructured Mesh Generation and Partitioning
Anita Anderson (AHPCRC-UM)
A workshop on Unstructured Mesh Generation and Partitioning, sponsored by the
AHPCRC and the University of Minnesota departments of Aerospace Engineering and
Mechanics (AEM) and Computer Science and Engineering (CS&E), took place on 5-7
October 1997. The Workshop was held at the AHPCRC headquarters in Minneapolis
and was organized by the following AHPCRC faculty researchers: Andrew Johnson
(AEM), George Karypis (CS&E), Vipin Kumar (CS&E), and Tayfun Tezduyar (AEM).

The Program began with a welcoming reception and pre-registration on Sunday
evening, which was held at the Hyatt/Whitney Hotel in facilities overlooking
the Mississippi River. The following morning, Tezduyar and Kumar provided the
opening remarks followed by the first session, which was chaired by Charles
Nietubicz of the Army Research Laboratory (ARL). Nietubicz's session included
talks given by Tom Hughes of Stanford University on Variational Multiscale
Method - a Paradigm for Subgrid Scale Modeling and Computational Fluid
Mechanics and by Mark Shephard of Rensselaer Polytechnic Institute on Parallel
Mesh Generation Using a Distributed Octree.
Session 2 was chaired by Hughes and began with a talk given by Tezduyar on Mesh
Generation and Update Methods in 3D Flow Simulation and Modeling. Tezduyar was
followed by Andrew Johnson (AHPCRC-UM) who gave a talk on Automatic Mesh
Generation/Regeneration Methods, and Keith Stein, Natick Research, Development,
and Engineering Center (RDEC), who gave a talk on Unstructured Mesh Computation
of Parachute Fluid-Structure Interactions. Stein is also a Ph.D. candidate in
the AEM department.

The first afternoon session, Session 3, was chaired by Kumar and began with a
talk given by Chris Walshaw from the University of Greenwich. Walshaw's talk
was on Partitioning and Mapping of Unstructured Meshes onto High Performance
Computer Architectures. Rupak Biswas of the NASA Ames Research Center followed
with a talk on PLUM: Parallel Load Balancing for Adaptive Unstructured Meshes.
The first day of the workshop ended with Session 4, chaired by Karypis, and
began with a talk given by Abani Patra of the State University of New York,
Buffalo, on Partitioning and Solution Methods for Adaptive hp Finite Elements.
Paul Plassmann, Argonne National Laboratory, followed with a talk titled
Parallel Algorithms for Unstructured Mesh Computation. The final talk of the
day was given by Shang Hua Teng, from the University of Illinois,
Urbana-Champaign on Unstructured Mesh Generation, Refinement, and Coarsening:
A Unified Approach.

A reception and banquet, which were held at the Hyatt/Whitney Hotel, followed
the day's activities. Jagdish Chandra, Deputy Director, Information Sciences
and Technology and Director, Atmospheric Research, ARL, served as the banquet
speaker. Chandra's banquet speech touched on the rationale for establishing
the AHPCRC in 1989, its successes and its promise for the future, as well as
its importance to the Army and to the greater Department of Defense community.
The Workshop resumed Tuesday morning with Session 5, chaired by Johnson. The
first talk of the session was given by Kumar on Multi-Objective Graph
Partitioning, and was followed by Karypis' discussion on Parallel
Repartitioning of Adaptive Meshes and Kent Danielson's (AHPCRC-AEM) talk on
Mesh Partitioning Approaches for Parallel Computation of Nonlinear Solid and
Structural Finite Element Analysis. Danielson is an AHPCRC staff scientist and
is located at the Corps of Engineers, Waterways Experiment Station (CEWES),
where he works on collaborative projects with CEWES researchers.

Session 6, the final session of the Workshop, was a panel session chaired by
N. Radhakrishnan (CEWES). The topic of discussion was Application Requirements
for Mesh Generation and Partitioning Libraries. The panel members included Sam
Holmes (Centric Engineering Systems), Carol Hoover (Lawrence Livermore National
Laboratory), Radhakrishnan, and Walter Sturek (ARL).
