**Subject: Difficulties with the NA-Net Machine**

We have been having some problems with the machine

running netlib and na-net. As it turns out, we have lost

all of the email sent via the na-net from Thursday, May 22, 11:45 pm

until Saturday, May 24, 5:00 pm. Sorry for the inconvenience.

**Subject: Did Roundoff Cause Patriot Failure?**

Article on page 1347 of the 13 March 92 issue of Science

``Fatal Error: How Patriot Overlooked a Scud''

The error in question was a roundoff error, or roundoff errors.

The description of what happened is not clear, to me.

I would be interested in more detail than is offered in the article.

I am hoping that someone out there might be able to offer a plausible

explanation.

**Subject: Looking for LU Decomposition Software on the CM-2**

I am doing research in quantum mechanical scattering of low energy atoms

off crystal surfaces. This involves solving large systems of Fredholm

integral equations of the 2nd kind, which I do using a Nystrom method

currently. The linear systems that are generated are quite dense and

complex valued. Currently I run calculations on the Cray Y-MP which are

up to order 6,000 . However, I need to run some now which will be closer

to order 10,000 . I have a fair amount of computer time on CM-2s, so

this is the platform I would like to use for these calculations, if possible.

Originally I designed my code to use the CMSSL software library that TMC

provides, however, I have not been having good experiences with it. For

this and other reasons (having to do with some iterative methods I am

interested in trying), I would prefer to do a LU decomposition of my

matrix. If anyone has access to software to do a LU decomposition of

a complex matrix on the CM, I would very much appreciate hearing from you.

**Subject: Mailing list for Auckland conference**

Within the next week or two, a package announcing details of the

"International Conference on Scientific

Computation and Differential Equations"

Auckland, New Zealand, 4 - 8 January 1993

will be sent to all members of a mailing list that

has been put together from miscellaneous sources.

The package will contain

(1) A colour poster for display, promoting the conference.

(2) Some copies of a brochure containing registration details,

a call for papers and other information.

(3) Some copies of the registration form for the meeting.

Although we have made reasonable efforts to make sure that

a copy of the package will go to most people likely to be

interested, there is no doubt that there are many gaps in

our list. Please let me (butcher@mat.aukuni.ac.nz or

na.butcher@na-net.ornl.gov) or Horst Gerlach (gerlach@mat.aukuni.ac.nz)

know as soon as possible if you suspect that we do not have your

institution on our mailing list and you would like to receive the

package on the conference. In this case please give us the

name and Air Mail address of a suitable contact person.

Many thanks, John Butcher

**Subject: Multidimensional Convolution**

I have a two dimensional diffusion problem that will involve numerical

convolution. All the convolution algorithms, mostly based on FFT, that I

can find in archives, IMSL, BCS, etc., are for one dimensional vector

convolution that compute

$$ z_j = \sum_{k=1}^n x_{j-k+1} y_k $$

However, I need a similar program that can compute a two dimensional equivalent

$$ z_{j,m} = \sum_{k=1}^n \sum_{q=1}^n x_{j-k+1,m-q+1} y_{k,q} $$

but cannot find such a thing. Has anyone ever seen such a thing on netlib,

lapack, imsl, simtel, etc. ?? Thanks for any information.

**Subject: Lancelot: A Nonlinear Optimization Package**

ANNOUNCEMENT OF LANCELOT RELEASE A

We are pleased to announce the release of LANCELOT, a software package

for solving nonlinear optimization problems. The package is

particularly appropriate for large examples. The embedded algorithms

are designed to provide convergence to a local minimizer from any

starting guess. The package is suitable for both unconstrained and

constrained problems.

General features include facilities to compute numerical and check

analytical derivatives, and to restart interrupted computations

automatically. A variety of direct and iterative techniques are

provided to solve the necessary linear algebraic subproblems. The

software also uses a full reverse communication interface for greater

flexibility and adaptability.

The package is written in standard ANSI Fortran77. It has been ported

to CRAY supercomputers, Digital VAX minis, Digital DEC workstations,

IBM VM/CMS mainframes, and IBM RISC System/6000 and SUN workstations.

A fully automated installation procedure is supported for all these

machines/systems. Single and double precision versions are available.

The program's dimensions may also be adapted to fit within machines

with different memory sizes.

Further information on the package is available from Philippe Toint at

pht@math.fundp.ac.be

NEW PUBLICATION FROM SIAM

Ten Lectures on Wavelets

Ingrid Daubechies

CBMS-NSF Regional Conference Series in Applied Mathematics 61

Wavelets are a mathematical development that may revolutionize

the world of information storage and retrieval according to many

experts. They are a fairly simple mathematical tool now being

applied to the compression of data--such as fingerprints, weather

satellite photographs, and medical x-rays--that were previously

thought to be impossible to condense without losing crucial

details.

LAPACK Users' Guide

E. Anderson, Z. Bai, C. Bischof, J. Demmel, J. Dongarra, J. Du

Croz, A. Greenbaum, S. Hammarling, A. McKenney, S. Ostrouchov,

and D. Sorensen

LAPACK is a transportable library of Fortran 77 subroutines for

solving the most common problems in numerical linear algebra.

LAPACK supersedes LINPACK and EISPACK, principally by

restructuring the software to achieve much greater efficiency on

vector processors, high-performance "superscalar" workstations,

and shared memory multiprocessors. LAPACK also provides extra

functionality, uses some new or improved algorithms, and

integrates the two sets of algorithms into a unified package.

LAPACK Users' Guide gives an informal introduction to the design

of the algorithms and software, summarizes the contents of the

package, and describes conventions used in the software and its

documentation.

LAPACK can be used to solve the most common problems in numerical

linear algebra: systems of linear equations; linear least

squares problems; eigenvalue problems; singular value problems;

matrix factorizations; estimating condition numbers

Additional improvements over LINPACK and EISPACK include: faster

run time; better error bounds; more and better condition numbers

Special features of the guide include: Quick reference guide to

the BLAS; How to convert calls to LINPACK or EISPACK to LAPACK;

Quick reference tables for Driver Routines

The authors have directed that royalty from the sale of this book

be placed in a fund administered by SIAM to help students attend

SIAM meetings and other related SIAM activities.

All purchasers of LAPACK Users' Guide will be notified of

software updates.

**Subject: Bibliography of Soviet Works on Interval Computations**

BIBLIOGRAPHY OF SOVIET WORKS ON INTERVAL COMPUTATIONS

To date authors from the former Soviet Union have published or prepared

for publication at least 500 papers in Russian devoted to various areas

of Interval Computations. Unfortunately, due to the language barrier

and problems with access, these works are practically unknown outside

the former Soviet Union. This publication is a step to remedy this

situation. The bibliography includes references to the works of

authors who were citizens of the Soviet Union when the works were

written.

The list, prepared in the Computer Center of the Siberian Branch of the

Russian Academy of Sciences (Krasnoyarsk) under the management of Dr.

Boris S.Dobronets, was taken as the basis for the bibliography. Later,

the list was corrected, appended and translated into English by Lyudmila

V.Kupriyanova (Saratov State University), and edited by Alexander

G.Yakovlev (Moscow, Institute for New Technologies) and R.Baker Kearfott

(University of Southwestern Louisiana).

The Editorial Board of the International Journal "Interval Computations"

can offer translation upon demand of these papers into English.

We can also supply foreign readers with copies of these materials in

Russian. To order copies, please contact the above representative in

this case, too.
