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
