Subject: Release of Serial Strassen Code

As part of the PRISM project, we have produced a portable, serial
version of Strassen's algorithm. We believe its speed, memory use and
other properties give it desirable features over other available
routines. It is plug-n-play with the BLAS 3 DGEMM routine and is
faster (except for small matrices where it is the same speed). The
code is freely available from by selecting
strassen.tar. The User's Guide, which is included with the software,
can be obtained separately by clicking on DGEFMM at the top of the
page. It gives more details about the nature and advantages of our
implementation. Our papers on this subject are also available at They can be
easily found by choosing the button to search on Strassen's algorithm.

We welcome any comments or suggestions.

Subject: ScaLAPACK Software Update

ScaLAPACK software update

ScaLAPACK is a collection of software for performing dense and band linear
algebra computations on distributed-memory parallel computers. ScaLAPACK,
version 1.4, includes routines for the solution of:
* Dense, band, triangular, and tridiagonal linear systems of equations,
* Condition estimation and iterative refinement for LU and Cholesky
* Matrix inversion,
* Full-rank linear least squares problems,
* Orthogonal and generalized orthogonal factorizations,
* Orthogonal transformation routines,
* Reductions to upper Hessenberg, bidiagonal and tridiagonal form,
* Reduction of a symmetric-definite/Hermitian-definite generalized
eigenproblem to standard form,
* Symmetric/Hermitian eigenproblem,
* Generalized symmetric/Hermitian eigenproblem, and
* Nonsymmetric eigenproblem.

Most routines are available in four data types: single precision real,
double precision real, single precision complex, and double precision complex.

In addition, we have provided prototype software to handle the following areas:
* Singular value decomposition,
* Out-of-core linear solvers for LU, Cholesky, and QR,
* HPF wrappers for a subset of ScaLAPACK routines, and
* The matrix sign function for eigenproblems.

Our software has been written to be portable across a wide range of
distributed-memory environments such as the Cray T3, IBM SP, Intel series,
TM CM-5, clusters of workstations, and any system for which PVM or MPI
is available. A draft ScaLAPACK Users' Guide and a comprehensive
Installation Guide is provided, as well as test suites for the collection.

The ScaLAPACK software is or will be part of the following vendor's
provided numerical software libraries: IBM, SGI/Cray, Fujitsu, NAG,
and Visual Numerics(IMSL).

For more information on the availability of each of these packages and
their documentation, consult the scalapack index on netlib. The URL is:
Comments/suggestions may be sent to

This software was developed in collaboration between researchers at the
Univ. of Tennessee, Univ. of California, Berkeley, and Oak Ridge National Lab.
ScaLAPACK is part of a larger project called the Scalable Libraries Project.
The Scalable Libraries project is made up of 4 components:
dense matrix software (ScaLAPACK)
large sparse eigenvalue software (PARPACK)
sparse direct systems software (CAPSS)
preconditioners for large sparse iterative solvers (PARPRE)
and is a collaborative effort between:
Oak Ridge National Laboratory Rice University
Univ. of Tennessee, Knoxville Univ. of California, Berkeley
Univ. of California, Los Angeles Univ. of Illinois, Champaign-Urbana
Funding for this effort comes in part from DARPA, DOE, NSF, and CRPC.

Subject: Computational Fluid Dynamics Workshop


One-Day Workshop on Software Engineering in CFD

Tuesday, 17th December, 1996

University of Oxford


An important issue in CFD is the suitability of codes used to program up
algorithms devised for the computational modelling of fluid flows. In particular
object-orientated programming is seen by some as the dominant language
type for the future. Both C++ and Fortran 90 have their champions but
whether there is a 'natural' programming language suitable for CFD remains a
matter for debate. In this workshop we seek to open up this debate and
provide a forum for speakers to bring out the benefits and disadvantages of
different programming techniques with a view to assisting CFD workers in
selecting an appropriate programming language.

The meeting will take place in the Computing Laboratory and is planned to
begin at 10.30 a.m. with coffee.

Speakers will include:

Dr C Farmer (GeoQuest Reservoir Technologies)
Dr R Lonsdale (AEA Technology)
Dr J T Hare (AWE)
Dr G J Shaw (NAG Limited)
Dr P I Crumpton (Oxford University)

Euro-Par is the annual European conference in Parallel Processing. It will
consist of a number of highly focussed workshops on all aspects of parallel
processing. In addition, there will be a number of high-level tutorials of
general interest plus a series of invited talks. All accepted papers will
appear in the proceedings published by Springer-Verlag in the LNCS Series.

Workshop #12: Applications of High-Performance Computing

This workshop aims at the development, implementation and experience of
industrial applications on parallel systems. Today, especially in industry,
software and algorithms still have to be improved or new ones developed,
and the unique chance exists to take the new target parallel computers into
account, already in the early design phase of industrial applications.

Topics of interest for this workshop include: existing industrial
in CFD, FE, chemistry, and others, and new applications like multimedia
support, data compression, geographical information systems, cognitive
recognition, embedded systems, parallel design and implementation, dynamic
distribution, computational steering, and others.

This spring, the University of Minnesota Supercomputer Institute and the
Institute for Mathematics and its Applications at the University of
Minnesota are sponsoring the Workshop on Mathematical and Computational
Issues in Drug Design. Please note that the dates for this conference
have been changed to April 7-11, 1997.

This workshop will bring together top researchers in computer-aided drug
discovery, computational chemistry, mathematics, and computer science to
present state-of-the-art research in both the science and the underlying
mathematics, and to identify new problems for possible collaborations.
General subject areas of the workshop will include receptor-based
applications such as binding energy approximations, molecular docking,
and de novo design; non-receptor-based applications such as molecular
similarity, conformational analysis, and structural diversity; molecular
dynamics simulations and protein folding simulations; plus related issues
such as drug delivery modelling and scientific visualization. The overall
goal of this workshop is to bring together scientists and mathematicians
to examine the current state of this very broad and interdisciplinary
field of research, and to identify the areas where cross-fertilization of
ideas and collaborative research might most effectively advance the
