**Subject: Simeon Fatunla**

Grieve, colleagues.

On 24th May I received by fax this brief message from Prof James

Ezeilo, director of the Nigerian Mathematical Centre in Abuja:

" I regret very much to have to report to you the tragic death of

our friend and colleague Prof Simeon Fatunla. He died on the

spot as a result of a head-on collision of his vehicle with

another vehicle at a point on the Auchi-Okene Road on Friday 19

May 1995. His driver also died on the spot.

Funeral arrangements are being organized by the University of

Benin and we will keep you posted.

May Prof Simeon Fatunla's soul rest in peace.

James O C Ezeilo "

Many people round the world will join with his family and his

associates, in mourning the death at age 51 of one of the

outstanding men of his generation and a leader of the academic

community in his country.

I will be in touch with colleagues both from Nigeria and

overseas, who have taken part in Simeon's Benin Conferences, to

decide what should be done to leave an enduring memorial of his

work and to help make permanent what he has begun.

**Subject: A Continuous Choice of an Eigenvalue**

I asked myself the following problem, without being able to answer it:

``Does there exist a continous function e from the space of 2x2 complex

matrices to the space of complex numbers, such that to each matrix

corresponds one of its eigenvalues?''

My first guess was that such a function does not exist. Indeed, take a matrix

with two different eigenvalues, for instance A= [0 1]

[1 0]

(eignenvals +1 and -1), and contruct a 'path in the matrix space', that is

a parametrization M(t) = [a(t) b(t)]

[c(t) d(t)]

such that M(-1) = M(1) = A, a, b, c, d continuous in -1<=t<=1,

and e(M(t)) = t, where e is our hypothetical eigenvalue function. This would

then show such a function cannot exist, as it would have two different values

on A.

Unfortunately all my attempts to build one such function have failed, so I

have come to doubt my conjecture.

Thanks to all, Larry

**Subject: Tests for Kalman Filter**

I have written a program that implements the Kalman Filter with

Driving Noise. I need a test case that is more complicated than

my simple one, yet not overly complex either.

Program or literature references would be much appreciated.

**Subject: PICL and PSTSWM software updates**

PICL and PSTSWM software updates:

PICL

PICL v2.1 is now available from http://www.epm.ornl.gov/picl .

The primary differences between versions 2.0 and 2.1 are new ports for the

IBM SP multiprocessors and for the Cray Research T3D. The SP port is built on

top of MPL, while the T3D port is built on top of the Cray Research

multiprocessor implementation of PVM. README files are provided with the

source code distribution that describe how to compile and use PICL in the new

environments.

The Portable Instrumented Communication Library (PICL) is an instrumented,

low overhead message-passing compatibility library, supporting

both portable message-passing and portable performance data collection

without incurring unnecessary overhead. PICL is a research tool developed for

and used in projects in performance evaluation and high performance

computing, and is made available to the community as a research tool.

(It is not a product.)

In my own work, PICL is used for portability when the underlying

native communication library is a good match to the PICL semantics.

When the most efficient native library is not a good match, like SHMEM on the

T3D, I still use PICL for collecting performance data on the user-level

events. An example of this usage can be found in PSTSWM, described below.

PSTSWM

PSTSWM v4.0 is now available from http://www.epm.ornl.gov/chammp/pstswm .

(It has been available for awhile, but the user guide has just been updated.)

PSTSWM is a message-passing benchmark code and parallel algorithm testbed

that solves the nonlinear shallow water equations on a rotating sphere using

the spectral transform method. PSTSWM was developed by to evaluate parallel

algorithms for the spectral transform method as it is used in global

atmospheric circulation models. Multiple parallel algorithms are embedded in

the code and can be selected at run-time, as can the problem size, number of

processors, and data decomposition. This flexibility allows the code to be

tuned on a parallel platform before benchmarking, thus evaluating the

multiprocessor on its ability to solve the numerical problem rather than

it ability to execute a given fixed parallel implementation. Six different

problem test cases are also supported, each with associated reference

solutions and solution and error analysis options.

As of 4/1/95, PSTSWM runs on the Cray Research T3D, the IBM SP-1 and SP-2,

the Intel iPSC/2, iPSC/860, DELTA, and Paragon (on both GP and MP nodes

and using either the NX or SUNMOS operating systems), the nCUBE/2 and

nCUBE/2S, across a network of SUN and IBM workstations, and on a Cray vector

machine (as a serial application). Message passing is implemented using MPI,

PICL, PVM, and/or native message passing libraries, with the choice being

made at compile time. In principle, it should also run on any other platform

on which MPI, PICL, or PVM is available.

To aid in tuning and in understanding the parallel performance, PSTSWM has

been instrumented for the collection of performance data using the PICL trace

and profile collection interface. The PICL implementation of the code must be

used in order to collect performance data on interprocessor communication

but a mixed PICL/native implementation is also provided that can be used to

collect data on events not related to message passing. In the mixed

implementation, the performance sensitive message passing uses native

commands and PICL is only used in the collection of the performance data.

**Subject: Report on TICAM Symposium**

The Symposium on Advances and Trends in Computational and Applied

Mathematics, sponsored by the Texas Institute for Computational

and Applied Mathematics (TICAM), was held April 20-22, 1995 in

Austin, Texas. The symposium focused on the many interdisciplinary

topics that bring together applied mathematics, numerical analysis,

computational sciences, physics, and engineering.

The symposium also helped to introduce the recently established

academic and research program in Computational and Applied

Mathematics (CAM) at The University of Texas at Austin. Drawing

faculty together from the Natural Sciences and Engineering, it

provides an important new opportunity for instruction and research

in this rapidly growing area. The program is interdisciplinary and

consists of faculty representatives from six engineering departments,

as well as the departments of Computer Sciences, Mathematics and

Physics with contributions from Chemistry and Astronomy. The program

offers study leading to both the Ph.D. and Master of Science degrees.

An important component in the CAM program is the initiation of a new

research institute, the Texas Institute for Computational and Applied

Mathematics (TICAM). TICAM is an organized research unit drawing

research faculties and students from the participating departments.

Interdisclipinary research projects include large-scale parallel

computing, structural acoustics, computational fluid dynamics,

computer simulation of micro-structure of composite materials, and

ongoing projects in computational physics.

The two and half day symposium was structured around a number of

thirty minute keynote presentations. Each day also included parallel

sets of contributed sessions. The contributing speakers were given

fifteen minutes to discuss their research. The organizers assembled

an impressive group of computational scientists for the symposium.

Although the backgrounds of all the speakers varied, the title of

computational scientist could aptly be used for all since the use

of computing was of central importance to the presentations. Indeed,

there was such diversity among the talks that only a few could claim

to not have learned something new about areas outside their own. The

symposium organizers are to be commended for a well coordinated event.

The overall quality and content of the presentations was high. To give

the reader an idea of the breath of the talks, the following

quickly reviews the symposium and subjects of each of the keynote

presentations.

Starting off the first day was Dr. Marye Anne Fox of the University of

Texas at Austin with a warm welcome for all the attendees. Professor

Tinsley Oden, the director of TICAM, followed with a brief introduction

to the activities and mission of the institute.

The first keynote talk was given by Jerry Bona of the University of

Texas at Austin. He considered the modeling of some of the aspects of

near-shore coastal dynamics. The goal was understanding how seashores

erode over time. In the second talk, Gene Golub of Stanford University

discussed the many applications of the theory of moments in numerical

analysis. One application is the efficient and stable computation of

the elements of the inverse of a symmetric matrix. Professor Golub

mentioned current research is underway that uses these estimates for

determining preconditioners for linear systems. Professor T.J.R. Hughes,

also of Stanford University followed with a talk concerning multi-scale

phenomena. The presentation examined a methodology for capturing the

various scales of phenomena in the finite element modeling of physical

processes. Jack Dongarra of the University of Tennessee and Oak Ridge

National Laboratory next discussed the SCALAPACK project. SCALAPACK is

the porting of the LAPACK software package onto parallel computers, in

particular, massively parallel computers. Professor Dongarra discussed

the many issues that arise in such an undertaking.

Starting off the afternoon session, Professor Bjorn Engquist of the

University of California, Los Angeles talked about multi-phase

computations in geometrical optics. Attempting to capture as much of

the frequency component of various equations describing geometrical

optics through different numerical schemes was discussed. Professor P.

Netaanmaki then followed with an overview of the work of the Laboratory

of Scientific computing he directs at the University of Jyvaskyla,

Finland. One particular research area he addressed was that of problems

in nonlinear optimal control. The final keynote talk of the day was given

by John Whiteman of Brunel University, United Kingdom, on discrete

schemes for hereditary problems of viscoelasticity. Professor Whiteman's

talk typified the synthesis of engineering, science and computational

mathematics of all the talks. The day concluded with a reception at the

Lila B. Etter Alumni center.

The second day of the symposium was started with a talk by Mary Wheeler

of Rice University. Professor Wheeler gave an overview of the research

being undertaken by her group on flow through porous media. Applications

include remediation of soils and aquifers and oil recovery. Simulating

the manufacturing process in microlithography was the subject of the next

talk given by Steven Orszag of Princeton University. Professor James

Bramble of Texas A&M University then followed with a mathematical talk on

the subject of least squares methods for Stokes equations. The fourth talk

of the day was given by David Young of the University of Texas at Austin.

The parallel implementation of alternating-type iterative solution methods

were discussed. The last keynote presentation before lunch was given by

Richard Ewing of Texas A&M University. Professor Ewing discussed an

interesting categorization of the multidisciplinary approach being used

to solve problems in environmental modeling. Following a break for lunch,

Randy Bank of the University of San Diego, La Jolla, examined the many

issues involved in the design of an algorithm for coarsening unstructured

meshes. Professor Tinsley Oden's talk followed and considered parallel

hp-adaptive methods for viscous flow. The methods described provide

efficient and robust criteria for deciding when to refine the mesh in an

adaptive fashion and increase the degree of the finite elements employed.

The goal was to develop a local error estimator to obtain near optimal

convergence rates. Professor Owe Axelsson of the University of Nijmegen gave

the last keynote presentation of the day. A detailed study was given on

developing scalable parallel multilevel algorithms for problems arising from

fluid flow. The day was concluded with presentations by the contributing

speakers. The symposium then retired to a reception at the Faculty center

followed by a banquet.

Ivo Babuska of the University of Maryland gave the first keynote

presentation of Saturday morning. Professor Babuska considered the many

complexities when using the finite element method on domains with unsmooth

boundaries and interfaces as well as the impact of rough coefficients.

The next hour was devoted to sessions by the contributing speakers.

Advances in element free and particle methods was the subject of the talk

given by Professor Ted Belytschko of Northwestern University. Professor G.F.

Carey of the University of Texas at Austin presented a survey and review of

the many numerical schemes for non-Newtonian flows. The final keynote

presentation of the symposium was given by Peter Pinsky of Stanford

University. He addressed the use of Galerkin least squares methods for

Hydrodynamic semiconductor device equations.

Professor Oden then concluded the half day session with some closing

remarks. In particular, he asked all the symposium attendees to thank

Ms. Ruth Hengst for a successful coordination of the event.

Finally, Professor Oden mentioned that a future issue of the Journal of

Computational and Applied Mathematics will contain papers by the keynote

speakers on their presentations.

(The author gratefully acknowledges Gene Golub and Ruth Hengst for their

comments on this report.)
