**Subject: Parallel Tridiagonal Matrix Solver**

I am looking for a fast parallel tridiagonal matrix solver to solve

the system Ax=b where A is tridiagonal and x and b are vectors. I

want to use this to solve systems of reaction diffusion equations

(parabolic PDE's).

Do you know if any source code exists for the partition method

of Wang (or improvements) or the cyclic decompostion method? Which

method is likely to be more efficient (I will be running my code on

a SGI Power Challenge)? The parallel versions of the tridiagonal matrix

in the SG libraries are quite slow (slower that the code in numerical

recipes).

Thanks.

**Subject: METIS, Unstructured Graph Partitioning Software**

METIS: Unstructured Graph Partitioning and Sparse Matrix Ordering System

Release 2.0 of METIS is now available.

We would like to announce the release of version 2.0 of the METIS package

for partitioning unstructred graphs (such as unstructured finite element

meshes) and for producing fill reducing orderings of sparse matrices.

METIS 2.0 contains a number of changes over METIS 1.0. The major changes

are the following:

* A new faster k-way partitioning algorithm has been implemented

that produces good partitions, and it is up to 5 times faster the

recursive bisection algorithm used in version 1.0.

* The algorithms have been extended to handle non-power of 2 partitions.

* A stand-alone library is provided to interface with the partitioning

and ordering algorithms of METIS.

* A number of modifications to better handle weighted graphs.

* Speed improvements, particularly in the ordering code. METIS 2.0

is about 10% to 15% faster than version 1.0.

* Better memory management.

Overview of METIS

Graph partitioning has extensive applications in many areas, including

scientific computing, VLSI design, and task scheduling. The problem is

to partition the vertices of a graph in k roughly equal parts, such that

the number of edges connecting vertices in different parts is minimized.

Graph partitioning is of particular importance in finite element

computations on parallel computers, since a good partition significantly

reduces the amount of communication, increasing the performance.

Graph partitioning algorithms are also used to compute orderings for

sparse matrices, in order to minimize the amount of fill and to increase

the concurrency that can be exploited during parallel direct factorization.

METIS is a set of programs that implement various graph partitioning

algorithms that are based on the multilevel paradigm.

The advantages of METIS compared to other similar packages are the following:

- Provides high quality partitions!

The partitions produced by METIS are consistently 10% to 50% better than

those produced by spectral partitioning algorithms, and 5% to 15% better

than those produced by Chaco multilevel.

- It is extremely fast!

METIS is 20 to 160 times faster than multilevel spectral bisection, and

5 to 30 times faster than Chaco multilevel, for a wide variety of a graphs.

Graphs with over 500,000 vertices can be partitioned in 256 parts, in

under a minute on scientific workstations. The run time of METIS is

comparable to (or even smaller than) the run time of geometric

partitioning algorithms that often produce much worse partitions.

- Provides low fill orderings!

The orderings produced by METIS are significantly better than those

produced by multiple minimum degree, particularly for large finite

element graphs. Furthermore, unlike multiple minimum degree, the

elimination trees produced by METIS are suited for parallel direct

factorization.

Obtaining METIS

METIS is freely distributed. Information on how to get the source code

is available on WWW at

URL: http://www.cs.umn.edu/~karypis/metis/metis.html

Alternatively, METIS can be obtained via anonymous ftp from

ftp.cs.umn.edu/dept/users/kumar/metis/metis-2.0.tar

Papers describing and analyzing the various algorithms implemented by

METIS can be retrieved via WWW from:

http://www.cs.umn.edu/users/kumar/papers

METIS has been written by George Karypis and Vipin Kumar, at the

Computer Science Department of the University of Minnesota.

If you have any questions or problems obtaining METIS, send

email to karypis@cs.umn.edu.

**Subject: International Linear Algebra Society Prize**

ILAS PRIZE

The Hans Schneider Prize in Linear Algebra

The Hans Schneider Prize in Linear Algebra is awarded by the International

Linear Algebra Society (ILAS) for research contributions and achievements

at the highest level in Linear Algebra. The Prize may be awarded for an

outstanding scientific achievement or for lifetime contribution. The Prize

is awarded every three years at an appropriate ILAS meeting, as decided

upon by the ILAS Executive Board. In any year in which a Prize is awarded,

there may be more than one recipient, within the discretion of the Board.

The first prize was awarded in 1993 to Miroslav Fiedler, Shmuel Friedland

and Israel Gohberg.

Procedure for determining the winner

A Prize Committee is established by the ILAS President upon the

recommendation of the ILAS Executive Board. The Committee solicits

nominations from members of the linear algebra community of people of

outstanding achievement in the subject and the Committee makes

recommendations to the ILAS Executive Board, which then makes the award.

(There shall be no restrictions on whom shall receive the Prize based on

sex, race, national origin, age or the time since the recipient took his

or her last academic degree). The recipient is notified at least two

months prior to the ILAS meeting at which the Prize is to be presented and

is also invited to give a talk at that meeting.

Nature of the Prize

The Prize consists of a plaque and a certificate containing the citation.

The Executive Board may also decide to make a cash award to the recipient

and/or make a contribution towards the expenses incurred in attending the

award ceremony.

Funding

The funding for the Prize comes from the interest accruing on a large

donation made to ILAS by Hans Schneider and a number of small

contributions from other people.

Next (second) Award

The second Prize will be awarded at the ILAS conference in Chemnitz,

Germany, in August 1993. The Prize Committee consists of:

Daniel Hershkowitz (chairman)

Richard A. Brualdi

Shmuel Friedland

Thomas J. Laffey

Peter Lancaster

Hans Schneider (ILAS President, ex-officio).

Nominations

Nominations are now being solicited from members of ILAS and the linear

algebra community in general of distinguished individuals judged worthy of

consideration for the Prize. In nominating a person, the nominator should

include a brief biographical sketch together with a statement explaining

why the nominee is considered worthy of the Prize. The nominator should

include references to the publications or other contributions of the

nominee which are considered most significant in making this assessment.

Nominations should be sent before October 20, 1995, to

**Subject: Computer Simulation of Aircraft and Engine Icing**

COMPUTER SIMULATION OF AIRCRAFT AND ENGINE ICING PHENOMENA

A ONE-DAY COURSE AND WORKSHOP

ORGANIZED BY CONCORDIA UNIVERSITY AND CERCA, MONTREAL, CANADA

FRIDAY, SEPTEMBER 22, 1995

Aircraft taking off from or landing at airports and/or flying

through clouds under adverse conditions may encounter the problem

of ice formation on aircraft surfaces and critical engine

components. This can jeopardize flight by increasing the weight,

altering the aerodynamic performance, and directly affecting

stability. While such problems have been studied and addressed

for over half a century by icing tests at specialized facilities,

more recently simulation by Computational Fluid Dynamics (CFD)

has proven itself a low-cost, flexible and effective

complementary tool for such studies. The current trend is to

bring to bear the latest computational and simulation tools to

understand and combat the icing problem. Such efforts have

resulted in codes, made available to aircraft/engine

manufacturers, airlines and regulatory agencies, on a national

basis.

We are seizing the opportunity of the meeting of the American

Helicopter Society in Montreal to invite 3 prominent scientists

in this area to speak of the efforts in their countries. The

speakers are from NASA (USA), ONERA (France) and NIAR (National

Institute of Aerospace Research, USA).

This timely course should be of value to all involved in icing

problems as it will illustrate the state-of-the-art in icing

problems simulation. It is structured to be of equal interest to

users of codes, operators of equipment and developers of

methodology, such as:

Aircraft manufacturers

Engine manufacturers

Airlines and aircraft operators

De-icing and anti-icing specialists

Icing tunnel scientists

Flight simulator manufacturers

Regulatory agencies

Instructors:

Dr. Mark Potapczuk, NASA-Lewis Research Center, Cleveland, USA

Dr. Didier Guffond, ONERA, Chatillon-sous-Bagneux, France

Prof. Ramesh Agarwal, Wichita State University and NIAR, USA

Cost: $200 CAD, including course notes, coffee breaks,

buffet lunch and taxes

$75 CAD, for students

Place: CERCA
