**Subject: Gordon Bell Prize Participants**

This year marks the tenth set of Gordon Bell Prizes and is my last

year administering the Prize. I'd like to collect the thoughts of all

who've participated over the years, both judges and entrants. I'm

particularly interested in "war stories". I'd also like to hear how

your participation affected your work, either positively or

negatively.

My goal is to produce a book on the subject, but should that not come

to pass, I promise to put lots of interesting stuff up on a Web site

for all to enjoy.

**Subject: PORT 3 Subroutine Library**

The PORT Mathematical Subroutine Library (third edition, released

in 1984) is a collection of Fortran 77 routines that address many

traditional areas of mathematical software, including approximation,

ordinary and partial differential equations, linear algebra and

eigensystems, optimization, quadrature, root finding, special

functions, and Fourier transforms, but excluding statistical

calculations. PORT stands for Portable, Outstanding, Reliable,

and Tested.

Parts of the PORT library, such as the framework (published in 1978

as TOMS Algorithm 528 by P. A. Fox, A. D. Hall, and N. L. Schryer),

are freely available from netlib, but getting the entire library has

hitherto required payment of a licensing fee. Recently, Bell Labs

has decided to make the whole PORT library available without fee

(or promise of support) for noncommercial use, under a non-exclusive

limited-use software agreement: see

http://www.bell-labs.com/project/PORT/

See also

A update file (version 1.6) for ScaLAPACK is now available. Details of

the modifications can be found in

http://www.netlib.org/scalapack/errata.scalapack

The following new and/or updated prototype software has been introduced:

* Alignment-restriction free PBLAS (version 2.0 ALPHA) using

logical algorithmic blocking techniques,

* Packed Storage routines for Cholesky factorization, symmetric eigenvalue

problem, and the generalized symmetric eigenvalue problem

* The matrix sign function for eigenproblems, and

Our software has been written to be portable across a wide range of

distributed-memory environments such as the Cray T3, IBM SP, Intel series,

SGI Power Challenge and Origin 2000, clusters of workstations, and any

system for which MPI or PVM is available. A comprehensive Installation

Guide is provided, as well as test suites for the collection.

The ScaLAPACK software is or will be part of the following vendor's

**Subject: N-D Rootfinding Book Recommendations**

I need to find roots in sets of nonlinear equations, and I'm looking for

recommendations for books that do more than simply derive the n-D Newton

method and leave it at that. Basically, I've read Forman Acton's Real

Computing made Real and Numerical Methods that Work and I really like

his treatment of the subject. He says up front that there's no general

method for solving sets of nonlinear equations, and then he goes on to

describe how to approach the problem, giving lots of examples. I think

I'd like more of the same, except I'm solving 2-D through 8-D equations,

while he restricts himself to 2-D for the most part (there are a few 3-D

examples, but not many).

Are there other books like this? Or, are there other must-have books

for solving nonlinear equations numerically (like say the Golub and Van

Loan of root finding or something :)?

Thanks,

Chris

It is intended that the lectures should be accessible to people (particularly

graduate research students) for whom the material is new, to enable them to

acquire reasonable competence in it, thus broadening their research horizons.

In addition, there will be an opportunity for participants to present

research seminars on their own work, including a small prize for the

best paper presented by a graduate student in each of the weeks.

**Subject: Workshop on Self-Similar Systems**

FIRST ANNOUNCEMENT

International Workshop "SELF-SIMILAR SYSTEMS"

Dubna, Russia, July 30 - August 7, 1998

GENERAL INFORMATION:

The Bogoliubov Laboratory of Theoretical Physics of the Joint

Institute for Nuclear Research organizes an International Workshop

`Self-similar systems'. The workshop will be held in Dubna, a

small quiet town surrounded by forest on the bank of the Volga

river, 120 km north of Moscow. It will start on Thursday morning

July 30 and end Friday August 7, 1998.

The Workshop will be devoted to diverse aspects of self-similar systems.

The main attention will be paid to mathematically justified theories (the

wavelet analysis, solvable models of self-organized criticality,

quasicrystals, etc). There will be a special session (around 5-6 August)

devoted to the commemoration of the centenary of Ya.L. Geronimus. This

will put a particular emphasis upon orthogonal polynomials (general theory

and classical, semi-classical, Laguerre-Hahn polynomials, etc).

An expected number of participants is 50-60, including a number of people

invited by organizers and students. There will be review lectures of 45 min

and shorter special seminars for experts. Selection of talks is by the

advisory and organizing committees. Due to the interdisciplinary character

of the workshop, there will be introductory mini-courses: ``Time-frequency

analysis and wavelets'' by B. Torresani, ``Wavelets and multifractals''

by S. Jaffard and ``Discretizations in Lie groups'' by A. Iserles.

TOPICS TO BE COVERED:

- Wavelets and other self-similar functions

- Self-organized criticality

- Multifractals

- Orthogonal polynomials

- Eigenvalue problems with the singular continuous spectra

- Quasicrystals

- Self-structuring phenomena and turbulence

First Call for Papers

Euro-Par is an international conference dedicated to the promotion

and advancement of all aspects of parallel computing.

The major themes of the conference can be divided into the broad

categories of hardware, software, algorithms and applications for

parallel computing. The objective of Euro-Par is to provide a forum

within which to promote the development of parallel computing both

as an industrial technique and an academic discipline, extending

the frontier of both the state of the art and the state of practice.

This is particularly important at a time when parallel computing is

undergoing strong and sustained development and experiencing real

industrial take up.

The main audience for and participants in Euro-Par are researchers

in academic departments, government laboratories and industrial

organisations.

Euro-Par is the premier European academic conference on parallel

computing and normally attracts about 350 participants.

Euro-Par is organised as a number of Workshops under the following

topics for which papers are solicited.

Support Tools and Environments

Performance Evaluation and Prediction

Scheduling and Load Balancing

Automatic Parallelisation

Parallel and Distributed Databases

Object-Oriented Programming

Symbolic Computation

Real-Time Control and Data Fusion

Data Warehousing and Data Mining

Theory and Algorithms for Parallel Computation
