Subject: Seeking 1956 De Vogelaere Report on Hamiltonian Systems
Prof. Ron Mitchell recently told me about a reference concerning
numerical methods for Hamiltonian problems:
Methods of integration which preserve the contact transformation property of
the Hamiltonian equations,
by Rene De Vogelaere,
Report 4, Department of Mathematics, University of Notre Dame, 1956.
The Physical Sciences Librarian at the University of Notre Dame was able
to confirm that the report was written between January and September 1956
and is of 14 pages in length. However, no copies are available.
The report would seem to be a very early reference in an area that is currently
extremely active--does anyone have a copy of the report, or information about
whether it was ever published?

Subject: C Program for Gauss Kronrod Quadrature
Does anyone know where I can find a Gauss Kronrod adaptive quadrature
subroutine (similar to the one given in: "Numerical methods and
software", by Kahaner, Moler and Nash) written in C or C++
(not converted to by f2c).
Thanks in advance.

Subject: Parallel BiMMeR Matrix Multiplication Routines
We would like to announce a new release of the BiMMeR parallel matrix
multiplication routines. These routines were developed by
Huss-Lederman, Jacobson, Tsao, Turnbull, and Zhang at SRC. They use a
virtual 2D torus wrap data layout and the Broadcast-Multiple-Roll
algorithm. The code has been recently converted to MPI, the message
passing interface standard, and can be executed on a wide range of
parallel machines. The following operations are now supported:
C = alpha*A*B+beta*C,
C = alpha*A'*B+beta*C, (A' is A transpose)
C = alpha*A*B'+beta*C,
for any number of nodes with an implied 2D topology.
For a detailed description of the algorithms used, see Matrix
Multiplication on the Intel Touchstone Delta by Huss-Lederman,
Jacobson, Tsao and Zhang, Concurrency: Practice and Experience, Vol. 6
(7), Oct. 1994, pp. 571-594. The code and accompanying reports are
available via anonymous ftp from ftp.super.org in pub/prism
or via a WWW browser from ftp://ftp.super.org/pub/prism. (The BiMMeR
code is in file bimmer.tar.Z, and the referenced article is in file wn14.ps.Z.)

Subject: New Book on Markov Chains
INTRODUCTION TO THE NUMERICAL SOLUTION OF MARKOV CHAINS
William J. Stewart
Princeton University Press
ABOUT THE BOOK:
It is often possible to represent the behavior of a physical system
by describing all the different states which it can occupy and
by indicating how it moves from one state to another in time.
If the future evolution of the system depends only on its current state,
the system may be represented by a Markov process. When the state space
is discrete, the term ``Markov Chain'' is employed.
In this book, the first to offer a systematic and detailed treatment
of the numerical solution of Markov chains, William Stewart provides
scientists on many levels with the power to put this theory to
use in the actual world, where it has application in areas as
diverse as engineering, economics and education. His efforts make
essential reading in a rapidly growing field.
Here Stewart explores all aspects of numerically computing
solutions of Markov chains, especially when the state space is
huge. He provides extensive background to both discrete-time
and continuous-time Markov chains and examines many different
numerical computing methods --- direct, single and multi-vector
iterative, and projection methods. Additionally, he considers
recursive methods often used when the structure of the Markov
chain is upper Hessenberg; iterative aggregation/disaggregation
methods that are particularly appropriate when it is NCD (nearly
completely decomposable) and reduced schemes for cases in which
the chain is periodic. There are chapters on methods for computing
transient solutions, on stochastic automata networks, and finally
on currently available software. Throughout, Stewart draws on
numerous examples and comparisons among the methods he so

IFIP TC 2 WORKING CONFERENCE
THE QUALITY OF NUMERICAL SOFTWARE: ASSESSMENT AND ENHANCEMENT
8-12 July 1996, Oxford, UK
First Announcement and Call for Interest
A working conference on The Quality of Numerical Software:
Assessment and Enhancement, will be arranged in the summer of
1996 in Oxford, England. This will be the seventh working
conference organized by the IFIP Working Group on Numerical
Software (WG 2.5) on behalf of the IFIP Technical Committee on
Programming (TC 2).
This message is an invitation to you from the conference
program committee to contribute your ideas for this conference.
At present we are very interested in suggestions regarding the
scope of the conference, who to invite to attend and who to
invite as speakers, and on which specific topics, and whether you
are interested in participating. The initial scope for the
conference is given below.
Previous working conferences arranged by WG 2.5 have focused
on performance evaluation of numerical software, numerical compu-
tation and programming languages, software for partial differen-
tial equations, problem solving environments, aspects of computa-
tion on asynchronous parallel processors, and scientific problem
solving environments. The number of participants is deliberately
kept small in order to preserve informality and allow substantial
time for interaction.
The conference program committee consists of Bo Einarsson
(Linkoping, Sweden), Brian Ford (Oxford, United Kingdom), Eric
Grosse (Murray Hill, New Jersey), Elias Houstis (Patras, Greece),
John Rice (West Lafayette, Indiana), Mladen Vouk (Raleigh, North

Symposium on Inverse Problems: Geophysical Applications
Conducted by SIAM with the cooperation of Gesellschaft fur

December 16-19, 1995
Marriott Tenaya Lodge at Yosemite
Fish Camp, California
CALL FOR PARTICIPATION
This symposium is the second of a series of symposia on
inverse problems and their applications. The first symposium held
June 27-July 1, 1994 in St. Wolfgang, Austria focused on applications
in diffusion processes. The second symposium will focus on the study of
connections of gravitational, seismic, electromagnetic, and thermal fields, with
the structure of our planet. These fields may be of natural origin, such as
oscillations caused by earthquakes and telluric currents, or they
may be induced as in seismic prospecting and geophysical prospecting by
electrical means. The interpretation of geophysical data leads to inverse
problems, i.e. from physical laws and the data of field measurements determine
the characteristics of the medium.
