**Subject: Parallel BLAS3 for SPARC**

In response to the query about an optimized BLAS3 for SPARC in the last

issue of NA Digest:

We use a library from DSS that is both optimized and parallelized. It

includes optimized versions of BLAS1 and BLAS2. It includes optimized and

parallelized versions of BLAS3 and LINPACK. For more details, contact the

company at scisoft@well.sf.ca.us.

Trivariate interpolation

Suppose we know f(x,y,z) for the points

(x,y,z)={(0,0,0),(0,0,1),(0,1,0),(1,0,0),

(1,1,0),(1,0,1),(0,1,1),(1,1,1)},

i.e at the corners of a cube. We then seek a simple expression for the

values of f(x,y,z) inside the cube.

The expression is going to be used in a computer program, where this

expression is required several hundred million times.

**Subject: Bibliography on Rank Revaling Factorizations**

RRF Bibliography - a Bibliography of Rank Revealing Factorizations

The RRF Bibliography is an attempt to create a bibliography of literature

on rank revealing factorizations, such as RRQR, RR-URV, RRLU, etc.

The bibliography is intended to include papers addressing all issues of

rank revealing factorizations, including:

- theoretical issues

- implementation issues

- applications

The bibliography currently consists of 48 entries, and it is available

in LaTeX format by anonymous ftp from wuli.uni-c.dk (129.142.6.204),

located in the directory pub/RRFbib. The file name is rrfbib.tex.

Please send comments and suggestions for new entries to me, as I

intend to keep the list updated.

**Subject: Physical Review E, Computational Physics**

On 1 January 1993 Physical Review A15 will become Physical Review E.

Beginning in January the journal will include a new subsection,

Computational Physics. The most appropriate papers for this section

will be those which seek to reach a wider audience of physicists than

that reached by specialized journals. We welcome papers describing

general computational methods that address significant physics

problems. Specific listings of programs, algorithms, etc., should be

reserved for supplementary material that would not appear in the

published article. Submissions to this new section are invited at

this time.

I might add that Irwin Oppenheim, the current editor of Physical Review

A15, will continue as editor of Physical Review E and that I will be

associate editor for the Computational Physics subsection.

Travel to Auckland for SCADE93 Conference

Because January is within the New Zealand tourist season,

travel to Auckland for participation in the International

Conference on Scientific Computation and Differential

Equations, January 4-8, 1993, is becoming increasingly difficult

to arrange. This reminder is to urge the many people who

have indicated an intention to take part in the conference

to arrange their travel to Auckland as soon as they possibly can.

We would, of course, also appreciate registration for the

conference at the earliest date possible, to assist the

organisers with detailed planning. For some airlines

there are already waiting lists for travel to Auckland during the

Southern Hemisphere summer and it may already be too late to

come on a date you might prefer and at a favourable price.

**Subject: Householder Symposium on Numerical Algebra**

SECOND ANNOUNCEMENT

THE HOUSEHOLDER SYMPOSIUM XII

MEETING ON NUMERICAL ALGEBRA

The Householder Symposium XII on numerical algebra will be held

during the week of June 13-18, 1993 at the UCLA Conference Center, Lake

Arrowhead, California, about a 2 hour drive from Los Angeles. This

meeting is the twelveth in a series, previously called the Gatlinburg

Symposia. It has been agreed to rename all subsequent Gatlinburg Symposia

to honor Alston S. Householder, one of the pioneers in Numerical Linear

Algebra and organizer of the first four Gatlinburg meetings. The meeting

is an international conference of experts in the field of Numerical

Algebra. The meeting has traditionally been held in an isolated location

and is very informal in style. Extended talks are given during

the day and special workshops organized by the participants in the

evening. There is no formal program, but traditionally a few topics are

emphasized; for this meeting this includes parallel computation issues,

signal and image processing, control, wavelets, nonsymmetric conjugate

gradient methods, domain decompositon and multilevel methods and

industrial problems.

The meeting is being organized by the Householder committee, in

cooperation with the SIAM Activity Group on Linear Algebra.

The local organizers are Tony F. Chan of UCLA and Gene Golub

of Stanford University. The venue is a first class rustic alpine

resort with modern conference and recreational facilities. The room

charge is $92 per person for a double room and $120 for a

single/private room and INCLUDES ROOM AND 3 MEALS A DAY

(spouses are allowed but not very young children).

It is hoped that we will have the whole conference center to ourselves.

There will be a modest registration fee (less than $100) to help

defray organizational costs.

The traditional format of the Householder Symposia requires that the

attendence be limited. The organizing committee invites all qualified

persons to apply to attend. For planning purposes, please let us know

of your intention to attend as soon as possible, preferably before December 1,

1992. We'll maintain a mailing list and keep you informed.

The actual application should consist of a vita and

an extended abstract (about two pages) of a paper you would present if

you desire to speak and are invited to speak.

The latter will be used by the committee in planning

the program. Material (preferably in machine readable form) should be

sent to us before February 1, 1993 (but the earlier the better) to:

**Subject: Workshop on Real-Time Vehicle Simulation**

Army Research Office Workshop in

Modelling and Analysis for Mechanical Systems and

Algorithms for Real-Time Vehicle Simulation

November 5-7, 1992

Brownestone Hotel

Raleigh, North Carolina

Motivation:

Computer simulation is playing a greater role in the design and analysis of

complex mechanical systems, the goals being improved designs and faster, more

reliable design processes. Often, the computer simulation must be performed in

conjunction with other devices or humans, such as in vehicle or flight simulat-

ors. In the case of human interaction it is essential that the computations be

carried out in real time. These issues are critical for military systems, as

the decline in defense spending shifts the emphasis from the procurement and

maintenance of vast military hardware to the capability for rapid high-techno-

logy responses to a wide variety of situations. They also have many obvious

implications for the improved competitiveness of American industry. Particular

applications to the Army include the design and stability analysis of vehicle

systems and weapons platforms. Thus, a workshop on Modelling and Analysis for

Mechanical Systems and Algorithms for Real-Time Vehicle Simulation is timely

and is both highly relevant and complementary to existing Army research activ-

ities. The need to bring together the diverse groups of engineers, control

theorists, numerical analysts, and computer scientists working in this field

led to the 1989 NATO Workshop on the Real Time Simulation of Mechanical Sys-

tems which was held in Snowbird, Utah. The meeting was uniformly praised by the

participants for the interaction that it spawned. Considerable progress has

been made since the NATO meeting. This ARO workshop may be considered to be the

first follow up meeting to the NATO workshop.

Themes of the Workshop:

The focus of this meeting is to bring together researchers from academia,

national laboratories, and Army scientists to stimulate collaboration on

problems of common interest arising the numerical simulation of the dynamics

of mechanical systems, especially vehicles. Topics to be discussed include

- Recent developments in sequential and parallel algorithms for

real-time simulation of ODEs and constrained systems, with

parallel and/or distributed computing architectures (e.g., trans-

puters) as an underlying issue;

- Delay-differential algebraic systems;

- Recent results of fundamental mathematical importance in differential-

algebraic equations (DAEs) related to constrained mechanical systems;

- New numerical methods/analysis;

- Investigations of stiffness in actual systems with DAE models;

- Modelling of vehicle systems;

- Software environments for real-time simulation

and related issues of adaptive nonlinear control. One important aspect of this

workshop is the intent to invite both Army and non-Army participants to pose

real problems encountered in complex vehicle simulation with the hopes of

stimulating discussion, posing solutions, and initiating future

collaborations.
