Answers to frequently asked questions:
1) The 1993 linear algebra survey and other observations on
the parallel computing influence may be found in print in "Large
Dense Numerical Linear Algebra in 1993: The Parallel Computing
Influence", International Journal of Supercomputer Applications,
Volume 7, Summer 1993, pp 113-128.
2) The LAPACK manual front and back covers contain matrices
that are inverses of each other, if you assume that the
small and capitol letters are reciprocals of each other.
The matrix is related to Hadamard matrices.

Subject: Updated Fortran 90 Benchmark Suite
Announcing the availability of the Quetzal Fortran 90 Benchmark Suite
The latest version of the Quetzal Computational Associates Fortran 90
compiler benchmark results are now available from anonymous ftp at
unmfys.unm.edu in the directory pub/quetzal. The benchmark codes
themselves are available as well and so is a review of the VAST-90
utility for converting Fortran 77 codes to Fortran 90. Please note
that this ftp site is different from the one used in the past.
This version of the benchmark suite differs in many significant ways
from the original one that was made available earlier this year.
In particular, some codes have been dropped from the suite and
several others have been added. The benchmark results have been
updated to reflect the performance of newer releases of the compilers
on the codes in the new benchmark suite.
Please contact me if you have any problems with the anonymous ftp
directory or other questions.

Subject: Comments on IEEE Arithmetic
Comments on IEEE Arithmetic
Jim Demmel
Computer Science Division and Math Dept.
University of California
Berkeley, CA 94720
demmel@cs.berkeley.edu
This is in response to the various comments on IEEE arithmetic in the
last few NA-Digests.
Many user complaints are a result of the IEEE floating point standards
754 and 854 specifying how systems "should appear" to the user, without
specifying any specific language bindings. These binding were not part
of the standard, because the committee members felt that writing a
standard demanding simultaneous changes in hardware, languages, compilers,
and perhaps operating systems (for exception handling) was unlikely to
to be accepted, or if accepted, implemented correctly. This "act of
cowardice" (in the words of W. Kahan) has unfortunately made it impossible
to write portable software which uses features of IEEE like exception
handling.
This confusion, which is still much better than the pre-IEEE situation
of different roundings, etc., has motivated some people to try to standardize
language bindings in a proposed Language Independent Arithmetic (LIA) ISO
standard. Unfortunately, I believe the LIA still does not give
adequate access to IEEE features, and indeed it was recently voted down
for this reason by the US/ISO committee. It is currently being redrafted,
and may still be accepted, but this is another story. W. Kahan has designed
his own set of language bindings for exception handling, which is easier to do
than a full set of environmental enquiries. He is interested in exploring
implementations with interested parties.
The IEEE standard specifically requires that the default behavior of a system
should NOT be to trap on exceptions, but to compute and/or propagate infinities
and NANs. One reason for this decision was to force manufacturers to implement
NAN and infinity arithmetic with reasonable efficiency, since otherwise
they would be tempted to take the easy way out (implementation via traps to
software) and so make infinities and NANs so slow that they would be impossible
to use effectively. Some manufacturers have still chosen to use software traps,
and others have not. For a recent paper on how to use infinities and NANs
to speed up numeric codes, and the price one pays for implementing them too
slowly, see the reference by Demmel and Li below [1].
All IEEE machines permit trapping on exceptions, and it should be a
prominently documented feature as to how to do this for any particular
system, either via a system subroutine call or compile line option.
It is unfortunate that compiler and system library writers do not
document this more clearly.

You've got to be kidding! Your programming experience through
those many years must have been restricted to a very limited class of
problems. One common example of when you would want to continue
execution after dividing by zero is when computing trigonometric
functions. Here is one example where IEEE arithmetic is a godsend:
exp(exp(-1.0/cos(chi)))
This is not a contrived example. It is used when computing Chapman
functions which are used in the theory of planetary atmospheres.
The ability of IEEE arithmetic to correctly compute trigonometric
functions when the argument is a multiple of pi/2.0 is what made a
fan of IEEE arithmetic.

Subject: Use of STRIDE for Initial-value PDEs
Use of STRIDE for initial-value PDEs
The code STRIDE, based on singly-implicit Runge-Kutta methods,
is at present undergoing further testing and development
especially for its possible use to solve PDEs with 1 space
dimension using either finite difference or finite element
discretizations. At present we have managed to solve some
classical problems such as Burgers equation and the KdV
equation. Part of the success of our method is the stability
of the underlying numerical methods but we have also found
great advantages in the flexible calling sequence used in our
integrator. This makes it possible, for example to solve
problems of the form My' = f(t,y), where both M and the
Jacobian of f have banded structures, without throwing away
this structure in the integrator.
We would like to hear about other codes that have been used for
this type of problem with some indication of successes or
difficulties that might have been encountered. We would also
like to extend our range of test problems and we ask for examples
of some reasonably challenging time-dependent PDE problems.

Associateships contingent upon available funding. The Associates
are of two types:
- Associateships in Computational Science and Engineering
(CS&E Associates) supported by the New Technologies Program in the
Division of Advanced Scientific Computing (DASC) in cooperation
with other NSF CS&E disciplines (CS&E Associates). The objective of
these Associateship awards is to increase expertise in the
development of innovative methods and software for applying high
performance, scalable parallel computing systems in solving large
scale CS&E problems.
- Associateships in Experimental Science (ES Associates)
supported by the Office of Cross Disciplinary Activities (CDA) .
The objective of the ES Associateship awards is to increase
expertise in CISE experimental science by providing opportunities
for associates to work in established laboratories performing
experimental research in one or more of the research areas
supported by the CISE Directorate.
These awards provide opportunities for recent Ph.D.s to broaden
their knowledge and experience and to prepare them for significant
research careers on the frontiers of contemporary computational
science and engineering and experimental science. It is assumed
that CS&E Associates will conduct their research at academic
research institutions or other centers or institutions which
provide access, either on site or by network, to high performance,
scalable parallel computing systems and will be performing research
associated with those systems. It is assumed that ES Associates
will conduct their research in academic research institutions or
other institutions devoted to experimental science in one or more
of the research areas supported by the CISE Directorate.

Subject: LAA Now Accepting LATEX Files
LATEX files for accepted LAA papers.
Elsevier Science Publishing Co. is now accepting LATEX files for
publishing papers in LAA and a LATEX macro file has been created
specifically for LAA. We hope that authors obtain and use these macros
for composing their papers. This reduces proof reading to a minimum,
among other advantages to authors, editors and the publisher. Below we
give a description of the process involved.
First, it should be noted that until final acceptance of a paper, the
editorial process is unchanged. Authors should continue to submit three
hard copies of their typescript to an editor. An electronic file is
not desired at this stage; although an author may vary this procedure
by agreement with individual Associate Editors. A LATEX file is
desired only at the time of final acceptance of the paper.
If an author wishes to submit a LATEX file if his/her paper is
accepted, he/she should inform the editor of this in the letter
accompanying submission. The author will then be asked to send the
LATEX file to the editor-in-chief either by the editor who recommends
acceptance or by the editor-in-chief who accepts the paper. The LATEX
file may be on a disk (preferably) or it may be sent by email. This
file must be identical to the hard copy of the paper accepted for
publication. It is essential that a diskette is clearly labeled with
the following information: the name of the authors, the email address
of the corresponding author, title of the paper, the LAA number, RFP
number (found in the letter of acceptance, if known). If the file is
sent by email, the same information should be commented in near the
beginning. The RFP (or LAA) number should also be included in the
"Subject" line.
Additional information on what this file should contain and on LAA
macros can be found in the LATEX guidelines available from IIC as file
LAA LATEX-G and the LAA macros themselves are available from IIC as
file LAA LATEX-M. Note that these files were revised in September
1993. The LAA macro codes should not be modified. If an author
believes that some modification is needed for his paper, he should
consult the editor-in-chief. Questions about the LAA macros should be
addressed to the LATEX Editor - Elsevier Publications, see the email
address below.
Authors should note that the copy editor will work from the accepted
hard copy only (and that is one reason why no changes should be made in
the LATEX file subsequent to acceptance). Authors will receive proofs
as usual. Corrections made by the copy editor and by the author at
proof stage will be incorporated in the LATEX file by Elsevier.

such as neural networks and geometric modelling.
All contributions should involve novel research. Expository papers are also
welcomed provided they are informative, well written and shed new light on
existing knowledge. The journal will consider the publication of lengthy
articles of quality and importance. From time to time special issues
devoted to topics of particular interest to the reader will be published
with the guidance of a guest editor. Ideas for special issues can be
communicated to the Editors-in-Chief.
Software of accepted papers is tested and made available to the readers.
Short communications, a problems section and letters to the
Editors-in-Chief are also featured in the journal at regular intervals.
Advances in Computational Mathematics is being published quarterly.
Authors are cordially invited to submit their manuscripts in triplicate to
