Subject: A Parallel Graph Partitioning and Sparse Matrix Ordering Library

ParMETIS: A Parallel Graph Partitioning and Sparse Matrix Ordering Library

We would like to announce the release of version 1.0 of the ParMETIS library.
ParMETIS is an MPI-based parallel library that implements a variety of
algorithms for partitioning unstructured graphs and for computing
fill-reducing orderings for sparse matrices. ParMETIS is particularly suited
for parallel numerical simulations involving large unstructured meshes.
For these computations, ParMETIS dramatically reduces the time spent in
communication by decomposing the mesh in a way that balances the load and
minimizes the number of interface elements.

ParMETIS's algorithms are based on the multilevel partitioning and fill
reducing ordering algorithms that are implemented in the widely used serial
package METIS. ParMETIS extends the functionality provided by METIS by
including routines that are especially suited for parallel computations and
large scale numerical simulations.

ParMETIS provides the following four major functions:
- Partition an unstructured graph.
- Improve the quality of an existing partition.
- Repartition a graph that corresponds to an adaptively refined mesh.
- Compute a fill-reducing ordering for sparse direct factorization.

Here is a list of some of the main features of ParMETIS:
- It quickly computes high quality partitions of very large unstructured
- It can take advantage of geometry information (when available) to speedup
the runtime of the partitioning algorithms without loss in quality.
- It can be used to improve (some times dramatically) the quality of
partitions produced by other partitioning algorithms.
- It can quickly compute high quality repartitions of adaptively refined
meshes. It optimizes both the number of vertices that are moved as well
as the edge-cut of the resulting partition.
- It can compute fill reducing orderings for sparse direct factorization.
It uses a node-based nested dissection algorithm that has been shown to
significantly outperform other popular ordering algorithms.

Obtaining ParMETIS

ParMETIS is distributed freely. Information on how to download the source
code is available on WWW at:


ParMETIS has been written by George Karypis, at the Computer Science
Department of the University of Minnesota. If you have any questions or
problems obtaining ParMETIS, send email to

Subject: Conference in Germany on Glass Production

Analysis and Simulation of Processes in Glass Production and processing
Kaiserslautern (Germany), October 9-10 1997

Glass has been a field for scientists and engineers for many years.
Although modern science and engineering technology have contributed enormously
to the efficiency of the glass industry, many questions still cannot be
answered. More and more, mathematical modelling with computer simulations
replace expensive practical experiments.
These simulations may help to understand the physical processes in detail
and lead to the optimization of the manufacturing process itself.
So they give both reduced costs and flexibility. The ECMI-GLASS-DAYS 97 will
provide a forum for discussion of work on the application of mathematics to
glass manufacturing processes. They are the continuation of the
first GLASS-DAYS, which took place in Eindhoven in 1994.
As a consequence ECMI (the Eoropean Consortium for Mathematics in Industry)
founded a special interest group working in the field of mathematical
modelling and simulation of glass.
Typical problems are viscous sintering and pressing of glass in moulds,
production of float glass, radiative heat transfer, foam formation in glass
The ECMI-GLASS-DAYS will also provide a forum for participants from
industry to pose some relevant problems to the mathematical community.
The second day will be dedicated to the discussion of these problems.

BLAS TECHNICAL FORUM, August 14-15, 1997, Portland, OR

We are planning a BLAS Technical Forum meeting on August 14-15.
The meeting will be hosted by Intel Corporation and the
meeting will be held at the Benson Hotel in Portland, OR (located
in downtown Portland and about 20 minutes from the airport):

Benson Hotel

For more complete registration/reservation information, please refer
to the BLAST webpage:

The Forum has been established to consider expanding the Basic Linear
Algebra Subprograms (BLAS) in a number of directions in the light of
modern software, language, and hardware developments. The first meeting
of the Forum was held in Nashville on February 19-20, 1996 and the
previous meeting was held in Dallas, TX on February 27-28, 1997.

Working groups have been established to consider the overall
functionality, possible extensions, and a lightweight interface
for the BLAS, as well as the short term goals of the forum. Other
functionality, possible extensions, and a lightweight interface
for the BLAS, as well as the short term goals of the forum. Other
subgroups have also been established, either to advise the current
working groups or as placeholders for future working groups on parallel
processing issues, sparse operations, and language binding issues.

We strongly urge and encourage attendance at the meeting
so that we can make tangible progress towards much needed standards.
Wide input is needed to help ensure that emerging proposals are useful
and acceptable to the community.

It is appreciated that it is not easy for everyone to attend the
meetings of the Forum, but we would nevertheless welcome your input
since we wish the discussion to be as open as possible, and the results
to reflect consensus from the community at large.

Please send us items you would like to see on the agenda
or that you would like to discuss.

We will plan to start the meeting at 8:00 am on Thursday, August 14th
and end by 1:00 pm on Friday, August 15th. Intel is providing
breakfast and lunch on both conference days.
