I am sad to report the death of Olga Taussky Todd on
Saturday, October 7, 1995 in Pasadena, CA. She was 89 years of age.
She had been, in my opinion, the most famous living female mathem-
atician in the world. She is survived by her husband, John Todd,
an eminent numerical analyst. Richard S. Varga.

Subject: New Network Optimization Package Available

Dear colleagues,

This is to inform you that there is available a new package, called
PPRN, for network optimization. The package is appropriate for solving a high
variety of network problems: single/multicommodity network flow problems,
with linear/nonlinear objective function and with/without linear side
constraints. Thus it can be viewed as a general package for many network
optimization problems (though it was originally designed for solving
nonlinear multicommodity problems with linear side constraints).

The code has been tested comparing its performance against other
codes. When solving pure linear network flow problems, it has proved to be
faster than alternative codes like NETFLO (J. Kennington) or RELAX-IV
(D. Bertsekas) in all cases tried of a battery of dimacs problems. When
solving linear multicommodity problems its performance was in general
better, though not in all cases tested, than that of MCNF85 (J. Kennington).
For nonlinear problems it has only been compared with general purpose packages
like MINOS (Murtagh and Saunders) and PPRN always outperformed it.

The package can work as an stand-alone code (reading the model
from a file and reporting the solution in another file) or as a subroutine
in a bigger user application (the communication with the user application
is made through parameters in this case). It can be called from Fortran and
C user applications.

The package is presented as a library and can be obtained via
anonymous ftp from (if this doesn't work, try to connect to, at directory pub/onl/codes/pprn. The package is available
from Sun and DEC-Alpha platforms. If you have a different architecture from
those, please contact us at There is also additional
information like some technical reports and papers describing
the package, an user's guide, some test examples, and a converter from dimacs
format to pprn format (this only for the case of linear single commodity

Should you have any comments or suggestions, you find trouble or
abnormal situations, or you have a different platform from those available,
please contact us at

This code has been released for academic use only. For other types
of usage, please contact with the authors at some of the ordinary or e-mail

Subject: Alpha Test Release of the BLACS for MPI

An "alpha test release" of the BLACS (Basic Linear Algebra Subprograms) for
MPI is now available. The BLACS are the communication layer used in ScaLAPACK,
the distributed memory version of LAPACK (Linear Algebra PACKage). Thus the
release of a MPIBLACS corresponds to a MPI port of ScaLAPACK.

We designate this release to be an alpha test version because there are
some unanswered questions regarding the BLACS' MPI usage. Although
the MPIBLACS have been tested fairly widely using MPICH (a popular MPI
implementation) we cannot say that they have been tested on even a majority
of the platforms to which MPI has been implemented. We encourage more user
testing so that we can gain greater confidence in this implementation.

We also hope to get user feedback on several MPI-related questions before
providing a full (and therefore relatively static) release. Users interested
in the BLACS (and by extension ScaLAPACK) based on MPI should send mail to, indicating that they wish downloading instructions for the
alpha test release of the MPIBLACS.

Subject: Surveys on Mathematics for Industry

Surveys on Mathematics for Industry

Surveys on Mathematics for Industry (Springer Vienna / New York) is
now entering its sixth year of existence. I want to take this
opportunity to
- urge you to subscibe to the journal
- issue a call for papers.

While in the starting years, we published nearly exclusively
invited articles, we want to continue opening up the journal for
submitted papers (which will, of course, also be refereed).

The main goal of the journal is to contribute to bridging the gap
between university and industry by
- the presentation of mathematical methods relevant for industry
- the exposition of industrial problems which are of interest to

To achieve this goal, the journal publishes (exclusively in
1. Surveys on new mathematical techniques
2. Surveys on established mathematical techniques with a new range
of applications
3. Surveys on industrial problems for which appropriate
mathematical models or methods are not yet available
4. Articles comparing mathematical models or methods for
particular industrial problems
5. Articles describing mathematical modelling techniques
6. Broad historical surveys
7. Articles of general interest about the use of mathematics in
8. Occasional book reviews and reports about conferences in the
field of Industrial Mathematics.

As you see, we publish only SURVEYS, not original research papers,
on topics in or relevant to Industrial Mathematics. We realize
that it is a lot of work to write a good survey and therefore
encourage prospective authors to submit short proposals to the
Managing Editor describing the subject area and the emphasis of
intended papers for a preliminary assessment of the suitability for
the journal.

Subject: Summer School at Leicester University

8th-19th July 1996

The Programme

The meeting will comprise two one-week modules, each of which can
"stand alone", although it is expected that many participants and speakers
will stay for the full two weeks.

Each week there will be three five-lecture courses given by the invited
lecturers as follows:

Week 1, 8th-12th July 1996
G. Cybenko (Dartmouth) "Neural Networks"
M. Plum (Clausthal) "Eigenvalue Problems for Differential Equations"
G. Strang (MIT) "Wavelets"

Week 2, 15th-19th July 1996

L. Greengard (NYU) "Multipole Methods"
C. Schwab (ETH, Zurich) "Hierarchical Modelling"
J. Xu (Penn State) "Multilevel and Domain Decomposition Methods"

The principal aim of the meeting is to gather together numerical analysts
and a team of internationally renowned experts for a period of intensive
study and research. It is intended that the lectures should be accessible
to people (particularly research students) for whom the material is new,
to enable them to acquire reasonable competence in it, thus broadening their
research horizons. Those with greater initial knowledge should end up being
able to work on significant problems in the area.

There will be a substantial amount of time available for research and
discussion with the assembled experts, who will make themselves available
for consultation in "office hours". Typeset lecture notes will be provided
by most of the speakers.

In addition, there will be an opportunity for participants to present
research seminars on their own work. It is anticipated that there will also
be book exhibitions and displays of computer software.
