**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.

MATHEMATICAL COMMUNICATIONS

MATHEMATICAL COMMUNICATIONS

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.
