At the end of this summer, we will be moving from

Cornell to Oxford, England. Nick will take up the

Chair of Numerical Analysis at the University, and

Anne will take a position with NAG, Ltd.

**Subject: Seeking Efficient Skyline/Profile Solver**

I'm looking for an efficient in- or out-of-core skyline/profile matrix solver,

written in either C or FORTRAN. Preferably something which is (or could be)

parallelized, but not necessary. Any help would be appreciated.

**Subject: User Level Interface to Level 3 Sparse BLAS**

The following paper has just been accepted for publication in ACM Trans Math

Softw. The revised technical report which has same text as

the accepted paper can be obtained by anonymous ftp to matisa.cc.rl.ac.uk

(130.246.8.22). The gzipped postscript is in file dmrvRAL95049.ps.gz

in directory pub/reports. For copyright reasons, this may not be available

for long, so download your copies early!

The referees were keen that we did not claim that this is a standard, but

hopefully this work will help to focus efforts at establishing standard

interfaces to the sparse BLAS.

The bibtex entry is:

author = {Iain S. Duff and Michele Marrone and Giuseppe Radicati

and Carlo Vittoli},

title = {Level 3 {B}asic {L}inear {A}lgebra {S}ubprograms for

New Journal

COMPUTING AND VISUALIZATION IN SCIENCE

Aims and Scope

Devoted to computational sciences - a field of major and

continually growing importance for both research and

applications, this journal provides the ideal platform for

scientists eager to cooperate in solving scientific and

technological challenges. The aim is to link professionals from

the diverse fields of

* mathematics, * computer science * physics, * chemistry, *

environmental sciences, * biosciences and * engineering.

The rapid development of computer technology has opened up new

perspectives, increased the importance of mathematical models and

created an urgent need for efficient algorithms. Reflecting these

trends, the journal has set itself the goal of publishing

pioneering methods and applications which precipitate the

solution of complex problems - or even make such solutions

possible at all.

Since visualization has become an important scientific tool,

especially in the analysis of complex situations, it is treated

in close connection with the other areas covered by the journal.

These areas include:

* mathematical modeling and analysis of model systems * numerical

methods and algorithms * development of simulation software *

optimization and control * parallel computing * visualization and

image analysis * computational physics and chemistry * structural

mechanics * fluid dynamics * environmental sciences * computation

in biosciences and medicine * modeling and computation in

engineering

As well as publishing this exciting material in print form,

Computing and Visualization in Science will also make the

documents available to subscribers electronically via a server.

THE WORKSHOP AS A PART OF A LARGER INITIATIVE

Our workshop initiative will be part of a series of workshops organized

by the "Associazione Amici della Scuola Normale Superiore", ASN

(Association of the Friends of the Scuola Normale Superiore) in the

field of Mathematics for Engineering Applications. Earlier workshops

were in the areas of CFD, Dynamic Control for Industrial Processes,

Image Treatment for both Industrial and Medical Applications. The

audience is typically very heterogeneous, academicians and others coming

from the R&D Departments of several italian industries.

**Subject: Neurocomputing at the Munich Stochastic Days**

Numerical approximation and numerical synthesis by neurocomputing usually is

not among the topics of a conference on Stochastics. Therefore I want to call

attention especially to Section 14 "Stochastic Optimization and Numerical

Approximation with Neural Networks" of the following Conference (abbreviated

1st announcement):

Special Interest Group Stochastics

1st announcement

MUENCHENER STOCHASTIK-TAGE (Munich Stochastic Days) 1998

March 24 - 27, 1998

at the

Federal Armed Forces University Munich, Neubiberg/Munich

with support of the

GAMM - Committee on "Applied Stochastic and Optimization"

IFIP - Working Group WG7.7 "Stochastic Optimization"

After the Stochastic Days in Marburg, September 13 - 16, 1993 and in

Freiberg Sachsen), March 26 - 29, 1996, the Special Interest Group on

Stochastics holds its third Stochstic Days at the "Universitaet der

Bundeswehr Muenchen" in Neubiberg.

Corresponding to the conferences so far in Marburg and Freiberg, the Munich

Stochstic Days are to give representatives of university, industry, and

administration the opportunity to present new results in the field of

stochastic - in theory and practice - and to discuss with colleagues.
