Subject: Interval Arithmetic Package for MATLAB

This is to announce

INTLAB - A Matlab library for interval arithmetic routines.

Elements (toolboxes) of INTLAB are

- arithmetic operations for real and complex intervals,
vectors and matrices over those including sparse matrices,
- rigorous (real) interval standard functions,
- automatic differentiation including interval data,
- automatic slopes including interval data,
- multiple precision including interval data,
- rigorous input and output,
- some sample verification routines.

All INTLAB code is written in Matlab for best portability. There is exactly
one exception to that statement, that is one assembly language
routine for switching the rounding mode of the processor (provided for
some hardware platforms).

Major objective of INTLAB is speed and ease of use. The first is achieved
by a special concept for arithmetic routines, the second by the operator
concept in Matlab.

Sample timings in seconds on my lame duck 120 Mhz Laptop for a
200x200 dense linear system are

0.56 sec real point system, no verification (pure Matlab),
3.35 sec real point system with verification,
4.23 sec real interval system with verification.

The code for generating the computing times is

n=200; a=2*rand(n)-1; b=a*ones(n,1);
tic, a\b; toc
tic, verifylss(a,b); toc
tic, verifylss( midrad(a,1e-10) , midrad(b,1e-10) ); toc

INTLAB code is easy to read and write, almost like a specification.
For example, for a given function "f" and some approximate value "xs",
the following code performs one step of Newton's iteration for xs:

x = gradientinit(xs);
y = f(x);
xs = xs - y.dx\y.x;

Note that y.dx is the Jacobian and "\" is the Matlab function for solving
a linear system. The corresponding code using verified operations looks like

x = gradientinit(intval(xs));
y = f(x);
xs = xs - y.dx\y.x;

As expected, nonlinear function evaluation slows down significantly due to
interpretation overhead. INTLAB is available for Windows and Unix systems,
prerequisite is Matlab Version 5. For more details and downloading, see

If you have comments etc., let me know. Have fun :-)

With best regards,

Siegfried M. Rump

Subject: Correctly Rounded Elementary Function Library

I am pleased to announce that ml4j has been posted on IBM's alphaWorks and
can be freely downloaded from
ml4j stands for Mathematical Library for Java. However, our library can be
called from C as well as from Java (we include an example of doing this).
The 12 functions are sin, cos, tan, asin, acos, atan, atan2, exp, log, pow,
sqrt and IEEEremainder. We did not include functions like floor, ceil etc.
since they are implemented correctly on most platforms. We did include
IEEEremainder (which has nothing to do with rounding) and sqrt (which is
correctly rounding on most platforms) just for completeness.
The unique feature of our library is the correct rounding, i.e. the result
produced by us identical to one obtained by rounding the exact (infinitely
precise) result to the nearest/even double precision number. And the
performance price paid for this is not too high (our library is written in
standard and portable C and it's speed is comparable to platform specific
libraries which do not round correctly).

You can download binaries for PowerPC/AIX, Pentium/WindowsNT and
Sparc/Solaris from alphaWorks. See the above URL for more details.

Any comments are more than welcome.

Subject: Prometheus, Parallel Multigrid Finite Element Library

We would like to announce the alpha release of the Prometheus library: a
fully parallel multigrid-based linear system solver for unstructured 3D
Finite Element problems. Prometheus takes a FE mesh distributed across
multiple processors, automatically generates all the coarse representations
and operators for standard multigrid algorithms, and solves the linear

Prometheus is designed for distributed memory machines, and has been used
to solve irregular 40 million degree-of-freedom problems, with large (10^4)
jumps in material coefficients and incompressible materials (v=0.49), on
960 IBM PowerPC processors with over 50% parallel efficiency. It uses C++
with MPI, is built on PETSc ( and ParMetis
(, and is correspondingly portable.
It has been tested extensively on the Cray T3E and IBM PowerPC cluster;
support for more platforms will be added depending on demand.

Prometheus has been developed for large scale solid mechanics problems and
has only been run on symmetric positive definite systems. However,
Prometheus can in principle be used for any problem for which effective
Krylov and multigrid algorithms exist (multigrid conference proceedings
are one source for such algorithms e.g., Prometheus uses
no explicit information about the partial differential equation being
solved (it only uses geometric information about the fine grid mesh). The
primary purpose of Prometheus is to construct standard multigrid operators
for unstructured FE meshes for use in multigrid preconditioners for Krylov
solvers. The current version supports only first order hexahedral and
tetrahedral elements; the next release will support shell and beam elements
as well.

Prometheus-1.0 documentation and library can be found at It is freely available. We
are interested in interacting with potential users to get feedback on the
effectiveness and usability of the algorithms and code, to help in the
continued development of Prometheus.

Subject: Computational Engineering Workshop in Honor of George K. Lea

Second Announcement and Registration Reminder
A Workshop on the Evolution and Future
of Computational Engineering
In Honor of the Retirement of
George K. Lea
from the National Science Foundation

June 17-18, 1999
Washington, DC

A workshop in honor of the retirement of George K. Lea from the National
Science Foundation will be held at NSF headquarters in Arlington, VA
(metropolitan Washington) and at George Washington University, on June 17
and 18, 1999.

Computational Science & Engineering (CS&E) is now widely accepted as a
third modality for scientific investigation and engineering design, along
with theory and experiment. It is easy to forget that it was difficult to
find institutionalized support for research in CS&E until relatively
recently. George Lea's program in Computational Engineering at the
National Science Foundation has long been an exception, and upon his
retirement from the NSF it is both appropriate and timely to take
retrospective and prospective looks at CS&E. George has not only helped to
define and promote the interdisciplinary content of CS&E; he has also
galvanized many interdisciplinary and inter-institutional collaborations
through his introductions of CS&E researchers to each other at national
conferences and at NSF-sponsored workshops.

Colleagues, friends, and former PIs of George --- and all who are
interested in retracing the past and speculating on the future of
Computational Engineering --- are therefore invited to a full day of
technical presentations and two surrounding evenings of social events at
the workshop.

Those tentatively scheduled to speak include:

Jacobo Bielak, CMU
Ray Chin, IUPUI
Charbel Farhat, CU Boulder
Karl Hess, UIUC
Bert Hesselink, Stanford
Daniel Joseph, Minnesota
George Karniadakis, Brown
David Keyes, ODU
