Subject: F90 Compiler Performance Benchmark Project
For some months I have been working on a set of Fortran 90 codes for the
purpose of performing a benchmark of the ParaSoft, NAG, and Pacific Sierra
Research Fortran 90 compilers (or translators, if you prefer). The
thrust of this project is to determine the performance of these compilers
on a variety of numerical problems, many of which are actual production
codes. I am performing my benchmark runs on a single processor Sparc 10.
I am nearing completion of my F90 performance benchmark suite and will soon
be running the final benchmark tests and writing up the results. With that
in mind, I am assembling an e-mail list to keep people up to date on this
project and for dissimination of the results. If you are interested in
being on this list, please send me some e-mail letting me know. If you know
of any other people who might be interested in this project, please send me
their e-mail address and I will contact them.

Subject: CUTE -- Constrained and Unconstrained Testing Environment
CUTE is now available
CUTE (Constrained and Unconstrained Testing Environment) is a set of Fortran
subroutines, system tools and test problems in the area of nonlinear
optimization and nonlinear equations. Its purpose is to
- provide a way to explore an extensive collection of problems (over 500
different test problems today)
- provide a way to compare existing packages (MINOS, LANCELOT, OSL, ...)
- provide a way to use a large test problem collection with new packages,
- provide motivation for building a meaningful set of new interesting test
problems,
- provide ways to manage and update the system efficiently, and
- do all the above on a variety of popular platforms (SUNs, DEC, IBM
workstations, CRAY, ...)
CUTE has been written by I. Bongartz, A.R. Conn (both at IBM, Watson Research
Center), Nick Gould (CERFACS, France) and Ph. Toint (FUNDP, Belgium). A LaTeX
manuscript detailing the package may be obtained by email from any of the
authors. It is also included in the distribution.
CUTE is written is standard ANSI Fortran 77. Single and double precision
versions are available. Machine dependencies are carefully isolated and
easily adaptable. Automatic installation procedures are available for DEC
ULTRIX, DEC/OSF/1, SUN SunOS, CRAY UNICOS and IBM AIX.
The package may be obtained in one of two ways. Firstly, the reader can
obtain CUTE electronically (and free of charge) via an anonymous ftp call to
the account at the Rutherford Appleton Laboratory camelot.cc.rl.ac.uk
(Internet i.d. 130.246.8.61, in the directory pub/cute), or at Facultes
Universitaires Notre-Dame de la Paix (Namur) thales.math.fundp.ac.be (Internet
i.d. 138.48.4.14, in the directory cute). We request that the userid is given
as the password. This will serve to identify those who have obtained a copy
via ftp.
Secondly, the package can be obtained on a floppy disk or magnetic tape at a
minimal price, intended to recoup the costs of media, packaging, preparation
and courier delivery. Potentially interested parties should contact Ph. Toint
for obtaining a suitable order form.

WORKSHOP ON RELIABILITY OF COMPUTATIONS
New trends in the assessment of quality for
numerical linear algebra software and algebraic processes.
Second Announcement
March 30--31, April 1 1993, TOULOUSE (FRANCE)
For an engineer or a researcher, having confidence in the results obtained
from large-scale computational codes and the robustness of the underlying
models is of the utmost importance. Indeed, the widespread availability of
supercomputers has replaced physical experimentation by intensive numerical
simulations, even for problems at the edge of instability.
Unfortunately, tools for obtaining information on the quality and the
reliability of computer results are rarely used in industrial environments.
However, there exist some new tools, developed in the framework of linear
algebra, which can offer the best possible solution to a given problem.
One has to discover and learn how to use them.
The aim of the workshop ``RELIABILITY OF COMPUTATIONS'' is then twofold :
* to present an overview of the new concepts influencing the design of
LAPACK, the Linear Algebra Library released in 1992,
* to show how the user can get meaningful information even from results
where all the digits can be wrong. Such computational problems are
considered so difficult that they are called ``impossible''.
