Subject: Garrett Birkhoff
I learned only from NA Digest of Garrett Birkhoff's death; I
had, to be sure, heard earlier that he was not well.
It is a loss that means a lot to me. Garrett was formally
my thesis director, but we had only sporadic sessions in that
relation, and I never really "studied with" him. In reality he
was much more important to me than our slight formal contact
would imply.
This was a long-distance influence. He always had (like
his father) a healthy respect for real applications reflected in
abstract structures, and a healthy breadth of curiosity, and I
learned from his example.
Some of the special interests of his youth -- especially
foundations of quantum mechanics and averaging operators -- were
things I worked on later, after he had finished with them. I am
one of the hundreds who made heavy use of his theorem on doubly-
stochastic matrices. Even lattice theory falls in this category:
by the time I wrote my thesis on a lattice-theoretic topic,
Garrett had pretty much moved on from that area. So there are
four special areas where you might say I was his disciple at half
a generation's remove.
Garrett's integrity and conscience were plain and clearly
felt to me. We never made a habit of talking politics, and
wouldn't always have agreed if we had, but my respect for the
core of his beliefs was one of the things that made me value him
as a teacher.
I hadn't seen him since his 80th birthday celebrations; that
must be true of many of his students and admirers. Numerous
though his public honors were, they fell short of his real
importance, so I hope he always felt the appreciation that we had
for him.

Subject: 2D and 3D FFT Code Wanted
I am trying to find source code for 2D and 3D uniprocessor FFTs--preferably
in C, but I can deal with Fortran too. (Netlib only seems to have 1D
FFT's.) I would like both complex-complex and real-complex transforms.
Ideally, they will allow the dimensions of the arrays to be any powers of
2, 3, or 5. I am also looking for shared-memory SMP implementations.
Thank you very much for any help you can provide.
Cordially,

Subject: SPAI Preconditioner Code Available
I have implemented a portable, parallel MPI implementation of the SPAI
(Sparse Approximate Inverse) preconditioner for unstructured sparse
matrices. The code also contains a BICGSTAB solver that is used to
test SPAI.
This code is available, free of charge, from:
http://lovelace.nas.nasa.gov/NAS/SPAI/download.html
SPAI constructs an explicit approximate inverse for an arbitrary real
sparse matrix, which is then used as a preconditioner in a Krylov
solver. The method has proved to be effective on very some difficult
problems. This code uses BICGSTAB for testing, but it is easy to use
other Krylov methods with SPAI. SPAI is complicated and expensive
compared to other preconditioners, but it is very effective for a
large class of problems and it is inherently parallel. If you use
iterative Krylov solvers on parallel computers you should consider SPAI.
A similar MPI/C++ implementation of SPAI is included in a much more
complete and portable package of Krylov solvers and preconditioners
called ISIS++. Consult the web page:
http://www.ca.sandia.gov/isis/isis++.html
SPAI was first described by Grote and Huckle:
M.J. Grote and T. Huckle, Parallel Preconditioning with Sparse
Approximate Inverses}, SIAM J. of Scient. Comput., to appear March 1997.
An online version of the paper can be obtained from:
http://www-sccm.stanford.edu/Students/grote.html/grote/spai.ps.gz
A very attractive feature of SPAI is that it is inherently parallel.
However, an efficient and scalable parallel implementation is not
straightforward. This code uses techniques for:
- One-sided communcation,
- Dynamic load balancing,
- Avoiding redundant communication.
A paper describing these techniques and some performance measurements
is under preparation and will soon be included in the software
distribution.

Subject: Fast Algorithms for Control, Signals and Image Processing
INTERNATIONAL LINEAR ALGEBRA SOCIETY (ILAS) SYMPOSIUM ON
"Fast Algorithms for Control, Signals and Image Processing"
June 6th, 7th and 8th, 1997
and
ILAS/IIMS
Session on Linear Algebra for the Canadian Mathematical Society
June 9th, 1997
Organized by
Institute of Industrial Mathematical Sciences (IIMS)
University of Manitoba
The objective of the three day meeting is to bring together people from the
areas of Control Theory, Signal and Image Processing and Computational
Linear Algebra to discuss recent advances, trends and future directions for
research on fast algorithms. This will offer a unique opportunity for
interaction among these groups and will provide a forum of interdisciplinary
communication that should encourage researchers to develop a new sense of
participation and a new perception of these areas as closely related
scientific disciplines.
The Symposium will feature a special emphasis on modern methods in
scientific computing and linear algebra relevant to digital control, signal
and image processing. For such applications it is important to consider
ingredients such as 1) sophisticated mathematical models of the problems,
including a priori knowledge, 2) rigorous mathematical theories to
understand the difficulties of solving problems which are often ill-posed,
and 3) fast algorithms for either real-time or data-massive computations.
Aspects of each of these three ingredients will be discussed by speakers in
the Symposium by way of short courses, invited and contributed lectures, and
invited and contributed mini-symposiums on relevant topics.
On June 6 a set of tutorial short courses will be given.
The Summer Meeting of the Canadian Mathematical Society (CMS) is being held
in Winnipeg on June 7, 8, 9, 1997 and hence overlaps with the ILAS Workshop
on June 7 and 8. A CMS Session on Linear Algebra organized by ILAS/IIMS will
be held on June 9, 1997.
The Winnipeg Symposium and short courses are the first of their kind for
ILAS.
On June 6 there will be an ILAS Workshop which will be open to participants
of the CMS meeting.

The Centre for Novel Computing (CNC) in the Department of Computer
Science is an inter-disciplinary research group with a focus on
(parallel) High Performance Computing (HPC). The centre has HPC
research tracks in applications (both numeric and non-numeric),
compilation, and run-time/operating systems. A number of posts,
associated with EPSRC and EC Framework IV funded projects, are now
available in the Centre, and we would welcome applications from people
with expertise in one of more of the following areas:
Application-oriented posts:
- numeric solution of PDEs,
- other scientific/numeric applications,
- non-numeric applications (particularly in the Information
Systems/Information Management areas).
Parallel programming expertise in a high level language, such as FORTRAN or
C/C++, (using directives, message-passing or thread-based approaches) would
be an advantage.
Operating System-oriented posts:
- operating system and run-time system design and implementation.
Experience in programming in C/C++ and assembler language programming for
SPARC/I386/ARM processors would be an advantage.
The posts are tenable for up to two years in the first instance, at a
salary of between \pounds 14,317 and 17,466, depending upon experience and
qualifications, on the RA 1A scale. For further particulars and an
application form please contact the Director of Personnel, The University

Official publication of the Croatian Mathematical Society-Division Osijek
"Mathematical Communications" publishes original papers, lectures
presented at the Mathematical Colloquium in Osijek and review articles
Preface
Osijek division of the Croatian Mathematical Society and the
Institute for Applied Mathematics in Osijek are starting to issue a
semi-annual journal "Mathematical Communications", which will
publish original papers, lectures presented at the
Mathematical Colloquium in Osijek, review articles, and various
Society news.
The first issue contains the lectures presented at the
Mathematical Colloquium in Osijek in the winter semester
1995/1996. The Mathematical Colloquium in Osijek started
in 1993 and is organized by the Scientific Section of the
Osijek division of the Croatian Mathematical Society,
together with the Institute for Applied Mathematics in Osijek.
The lecturers of the scientific colloquia are researchers
from Croatian universities and from abroad. They usually
give a report on their own recent results, present parts
of their Ph. D. theses, or give overview of recent trends
in various branches of mathematics and its applications.
These lectures are primarily intended for the faculty members
and students of the "Josip Juraj Strossmayer" University
in Osijek, but may also be of interest to people working in
computer centers and others.
Some of the lecturers of the educational colloquia are teachers from
Croatian universities or secondary schools. In these
lectures they usually present their own ideas and approaches
to teaching particular subjects, or discuss a historical
topic connected to mathematics and mathematicians. These lectures
are primarily intended for highschool teachers.
