ALBERT BOOTEN

This Monday morning we received the sad news that our colleague

Albert Booten (Dr. J.G.L. Booten) passed away last Sunday, November 12.

His death was completely unexpected, his heart failed during a

sports event.

Albert was only 33 years old. Since two years he held a

position as a postdoc at CWI in Amsterdam. Whereas his

background was in Physics, he got more and more interested

in Numerical Linear Algebra. He was involved in a project

for the computation of eigenvalues for very large matrices

arising in MHD. This work was presented at the HPCN Conference

in Munich (1994) and at the recent ICIAM Conference in Hamburg.

Last Friday he presented a poster with recent results at a

Symposium in Eindhoven and went for dinner with close colleagues

afterwards.

Albert was an able scientist and a very friendly person, and

we will miss him very much.

**Subject: Forsythe/Golub Reprint Files**

Friends,

During my 1/3 of a century at Stanford, I have collected a vast number

of papers and reprints. Many of these papers are not easily available

and of great historical interest, eg David Young's thesis. I also

have at my disposal the files of George Forsythe with his comments on

many lectures. The CS department is about to move into a new building

--- The Gates Building, and there will not be any storage space

available. Does anyone have any suggestions as to how to dispose of

these papers?

**Subject: Mesh Generation for Volcano Model**

I'm a reasearcher of volcanology in Catania, Italy.

I'd like to model a dike (a magma intrusion in a volcano) with a finite

elements approach. My idea is to create a mesh of brick elements that have

to represent Mt. Etna (Sicily) and to produce in an internal brick a force in

order to get the associated field of stress.

Until now, I'm using very simple mesh geometries: an external cube and a little

internal cube (my dike).

I'm using a public domain Finite Element program (FElt by J. Gobat and D.

Atkinson) and an house-made mesh generator program. I'm facing with several

problems:

1) Memory problems: FElt needs somethuing like 18 Mb for 300 elements: for my

problem 300 elements are really few;

2) Complex mesh generations: I'd like to describe the form of a volcano...

I'd like suggestions of ANY kind in how to resolve these problems and,

of course, your point of view on the application I'm actually studying.

Thanks in advance,

**Subject: DASSL and High Index DAE's**

Digest Request

I'm chemist (PhD student) and I'm trying to model the chemical reactions

which take place in the reactor. Although its a simple reaction, the system

can only be described with DAE's. I'm trying to solve the system but have

already encountered some problems since the index of the system is not equal

to one. I know their are several codes which solve DAE problems

(DASSL,LSODI), but they are only capable of solving DAE's with index one.

I'm just getting into the subject of modeling so I am not very familiar with

the DASSL code (I just now how to use it). I was wondering if their are

methods/codes which can solve higher index problems ?

I also have another problem also concerning DAE's and it has to do with

inconsistent initial conditions. I was wondering if you have come by a code

which can handle inconsistent initial conditions or a code which computes

initial conditions. I hope you are willing to help me with my problems.

If you have advice or suggestions for references, I would greatly

appreciate hearing from you.

Thank you

**Subject: Interpolating Scattered Data**

Dear Members,

We are working at modeling and simulation of transport of contaminants in

porous media.

We are looking for a public domain package that interpolates 2D or 3D

scatter data and provides as output a grid of values.

Each scatter point is defined by (x,y) or (x,y,z) location and one or more

scalar values.

We would be very grateful also to anyone able to provide us with some

information about interpolation in case faults are present.

Best regards.

**Subject: New Parser/Solver for Semidefinite Programming Problems**

SDPSOL, version alpha available via anonymous ftp

SDPSOL is a parser/solver for semidefinite programming (SDP) problems

with matrix structure.

Semidefinite programs arise in several applications, e.g., control

theory, statistics, and combinatorial optimization. SDPSOL allows the

user to specify SDPs in a convenient form that is close to the natural

mathematical problem description. After parsing the problem

description, SDPSOL solves the SDP using a primal-dual interior-point

method, and reports the results in a convenient form. SDPSOL works

as a stand-alone program, with ascii input/output, and can also

read/write Matlab binary data (.mat) files.

The current implementation DOES NOT exploit the matrix structure in

the SDP solver (which is SP, also available via anonymous ftp), and hence

is not particularly efficient. But it is (we hope) easy to use, and

does work quite nicely on small and medium size problems (say, a hundred

or fewer variables, and matrices of size 30x30 or so). We hope to

develop a more efficient version, with upward compatible syntax.

SDPSOL is available via anonymous ftp to isl.stanford.edu in

/pub/boyd/semidef_prog/sdpsol. It can also be accessed via WWW from

URL http://www-isl.stanford.edu/~boyd.

Comments, suggestions and bug reports are welcome.

**Subject: SYISDA Parallel Eigensolver Package**

We are pleased to announce a new release of the parallel SYmmetric

Invariant Subspace Decomposition Approach (SYISDA) eigensolver

package. These routines find all the eigenvalues and eigenvectors of

real symmetric diagonalizable matrices and can easily be adapted to only

resolve a certain part of the spectrum. (We are considering this

option for a future release of the code. If interested in this

option, please contact us.) All routines use MPI for

their message passing. As a result, they should run on any machine

which supports MPI. The code has been tested extensively on a wide

variety of parallel architectures and test cases. There is also a

User's Guide which provides directions on installing the package and

explains the user interface.

This package is part of the PRISM (Parallel Research on Invariant

Subspace Methods) project. There are a large number of technical

reports, conference papers, and working notes available via anonymous

ftp from ftp.super.org in pub/prism or via a WWW browser from

ftp://ftp.super.org/pub/prism. There is a README file which lists all

of the reports/code contained in that directory. The code and User's

Guide are located in file prism_syisda.tar.Z.

Please feel free to contact us at prism@super.org if you have any

problems or questions.

Basic Parallel Strategies for Scientific Computing

One Day Course

29th November 1995

Typical Scientific Computing problems such as Computational Mechanics

(CM) and Computational Fluid Dynamics (CFD) applications, with their

large CPU requirements but reasonably sparse connectivity patterns,

are potentially in an excellent position to exploit the emerging High

Performance Computing (HPC) technologies to obtain a far greater throughput

of results.

This one-day course provides an introduction to the principles

behind parallel scientific computing such as message passing

data/problem decomposition and programming paradigms.

The course will be run by the University of Greenwich, under the auspices

of the London & South-East centre for High Performance Computing (SEL-HPC).

SEL-HPC is a JISC funded consortium comprised of the London Parallel

Applications Centre, the University of Greenwich & the University of

London Computer Centre, formed in response to the new technologies initiative

in HPC. Further information about its activities can be found at
