Subject: Formal Proofs on Floating Point library

Dear NA-Net'ers,

The "Formal Proofs on Floating Point" library (FP2) is a set of formal
definitions and theorems (including proofs) to reason about floating
point numbers. It is now stored in the "FP" section of NetLib for
public use. It enables users to formally define types and operations of
floating arithmetic and to deduce properties using a mechanized proof

This library was first designed by Marc Daumas, Laurent Thery* and
Laurence Rideau*. Contributors now include Sylvie Boldo*, Jean-Michel
Muller, Laurent Fousse*, Ren-Cang Li and Guillaume Melquiond*.
Contributors that were directly interacting with Coq are outlined by a

Latest developments include:
- Proved algorithms for argument reduction
- Software emulation of the FMA using rounding to odd
- A few properties from Prof. W. Kahan
- Results on the ulp of the inverse of a floating-point number from
Dr. P. Markstein
- A link to the IEEE-754 standard
- Radix-independent algorithm to compute the exact error of a
- Error of a floating-point division or square root
- Conditions for a*x+y to be faithfully computed

Sources are in the "source" directory and are to be compiled with
version 8.1 of Coq.

Detailed documentations are in the "doc" directory and start with the
"index.html" file.

Subject: Computing a low rank update of a morally triangular matrix

Several savvy NA Digest readers have commented that my tool for
remembering the difference between merely, morally, and psychologically
triangular matrices did not actually include definitions of the same.
I apologize for the oversight. If L*U=P*A, then (P'*L)*U=A, and P'*L
is triangularly moral. Thus, please insert between stanzas 1 and 2
of my definition posted last week this very low and very rank update:

If row i less than column j
gives L sub i j zero, say,
that does make me it's very clear,
a matrix mere triangular.

Premultiply by P transpose;
pivot row swaps of L, suppose.
That's the process that gives to me
triangular morality.

But if my columns, one or all
for reasons psychological
are also swapped that makes me be
triangle psychologically.

You can read the revised tool in its entirety at ,
along with an illustration by J. Tenniel of some very
filled-in sparse factors L and U.

Subject: 4th Intl. Conf. on Multiscale Materials Modeling (MMM-2008), Oct 2008

The School of Computational Science at Florida State University is
pleased to announce the Fourth International Conference on Multiscale
Materials Modeling (MMM-2008). The conference will take place October
27-31, 2008 at Florida State University, Tallahassee, Florida, USA.

This biennial conference is the world’s largest theoretical and
computational materials science forum aiming to disseminate the
latest development in the multiscale materials modeling field. This
field transcends the boundaries between materials science, mechanics,
physics and chemistry of materials, and mathematics and computational
science. Materials predictions with unprecedented levels of accuracy
are now being made in areas including basic materials structure and
defects, microstructure evolution and materials response under
extreme conditions, and microstructure-property relationships, which
creates the basis for computational materials design and the
potential for advanced technological applications.

The MMM-2008 conference encourages participation from academia,
national laboratories, and industrial research facilities worldwide.
The conference solicits theoretical, computational, and experimental
contributions addressing all multiscale materials modeling issues.
The following symposia are being organized:

- Mathematical issues in multiscale materials modeling
- Statistical methods for materials deformation and failure
- Multiscale mechanics
- Multiscale modeling of microstructure evolution in materials
- Computational materials design
- Multiscale modeling of radiation effects in materials
- Computational modeling of biological and soft condensed matter systems

For more information about the conference, we invite you to visit the
conference website: The abstract submission window
is October 2008 through February 2008. Pre-registration is now open.
You are highly encouraged to pre-register as early as possible by
following the "Deadlines and Announcements" link at the MMM-2008

We ask that you kindly circulate this news item to interested

Subject: Sixth European Workshop on Automatic Differentiation, Nov 2007

Sixth European Workshop on Automatic Differentiation
Thursday 15th and Friday 16th November 2007
INRIA Sophia-Antipolis, France

This 2-days workshop continues the series of the EuroAD Automatic
Differentiation workshops, taking place twice a year. EuroAD workshops
are organized jointly by the University of Hertfordshire, UK,
Cranfield University in Shrivenham, UK, RWTH Aachen University,
Germany, and INRIA Sophia-Antipolis, France. These workshops provide a
forum for the presentation of theoretical developments in and
applications of Automatic Differentiation (AD) and adjoint methods.
The workshop is informal and presentations on subjects such as work in
progress, problem areas for AD, or possible application areas, as well
as completed work are welcome. We particularly encourage PhD students
and those new to the field to attend and present their work.

We welcome every researcher who will present their work on AD theory,
AD tools, or applications of AD. A particular emphasis will be put on
applications of AD to Earth Sciences. This involves topics such as
adjoints of unsteady simulations, variational data assimilation,
interactions between 4D-var data assimilation and other methods,
and applications to meteorology or oceanography.
