Subject: BLAS with 64-bit Integers

Are there plans for a BLAS standard that uses 64-bit
integers? The CBLAS just uses int's, not long's.
Sun has their own standard for BLAS with 64-bit integers,
and SGI has another (which is different). So does Compaq.
For example, Sun's 64-bit dgemm is called dgemm_64.
The Fortran interface takes integer*8 arguments.
The C interface takes "long" arguments.

32-bit ints are getting limiting, since with
signed pointer arithmetic and integer indexing,
only 2GB of memory can be used. But there seem to be
no standard way of addressing this issue in the BLAS.
Each vendor is going their own direction, which makes
porting rather interesting ...

Subject: COIN-OR Open-Source Coding Contest

The COIN-OR Open-Source Coding Contest: Win an IBM ThinkPad.

At the 2000 International Symposium for Mathematical Programming (ISMP),
COIN-OR ( was launched by IBM Research with the goal
of promoting "open-source" software for operations-research professionals.
Our lofty mission was to explore an alternative means for developing,
managing, and distributing OR software so that OR professionals could
benefit from peer-reviewed, archived, openly-disseminated software (much in
the same way we already benefit from theory). In November 2002, a
milestone toward the project's long-term objectives was reached when the
INFORMS board unanimously accepted a proposal to become the new host of the
COIN-OR initiative. To celebrate, we're throwing a contest!

Visit to find out how you can win an
IBM ThinkPad. Prizes will be awarded August 2003 at the 2003 ISMP in
Copenhagen, Denmark.

Subject: Textbook, Numerical Analysis in Modern Scientific Computing.

Dear Colleagues,

May I draw your attention to the recent revised edition of the textbook

Numerical Analysis in Modern Scientific Computing.
An Introduction

by Peter Deuflhard and Andreas Hohmann.

The book directs the reader to a selection of useful elementary
numerical algorithms on a reasonably sound theoretical basis, which
is built up within the text. The primary aim is to develop
algorithmic thinking -- emphasizing long-living computational
concepts over fast-changing software issues. The guiding principle is
to explain modern numerical analysis concepts applicable in complex
scientific computing at much simpler model problems. For example, the
two adaptive techniques in numerical quadrature elaborated there
carry the germs for either extrapolation methods in ODEs or multigrid
methods in PDEs, none of which are actually treated in the book.
Wherever appropriate, the presentation draws on geometrical
intuition, supported by a large number of illustrations. Numerous
exercises are included.

The text will appeal to undergraduate and graduate students as well
as researchers in mathematics, computer science, science, and
engineering. It is definitely also addressed to practical
computational scientists who, via self-study, wish to become
acquainted with modern concepts of numerical analysis and scientific
computing on an elementary level. The sole prerequisite is
undergraduate knowledge in linear algebra and calculus.


1. Linear Systems
2. Error Analysis
3. Linear Least-Squares Problems
4. Nonlinear Systems and Least-Squares Problems
5. Linear Eigenvalue Problems
6. Three-Term Recurrence Relations
7. Interpolation and Approximatikon
8. Large Symmetric Systems of Equations and Eigenvalue Problems
9. Definite Integrals

Subject: SPEC Releases High-Performance Computing Benchmark

SPEC HPG Releases New Benchmark Suite Based on
High-Performance Computing Applications, MPI and OpenMP

WARRENTON, Va., January 9, 2003 -- The Standard Performance Evaluation
Corp.'s High-Performance Group (SPEC HPG,
announces SPEC HPC2002, a new benchmark suite based on high-performance
computing (HPC) applications and the MPI and OpenMP standards for parallel

SPEC HPC2002 is targeted at those who evaluate performance for HPC systems,
including users, system vendors, software vendors, and researchers. It uses
a set of actual applications to measure the performance of the computing
system's processors, memory architecture, operating system, parallel
libraries, and compilers.

"The real-world applications in SPEC HPC2002 provide the best
industry-standard way to measure capability and scalability of HPC
systems," says Kaivalya Dixit, SPEC president. "MPI and OpenMP extend the
standardized SPEC approach to encompass accurate multiplatform performance
measurement for parallel processing."

SPEC HPC2002 improves upon and replaces the SPEC HPC96 benchmark suite. The
new benchmarks include full applications and message-passing protocols that
complement the recently released SPEC OMP benchmark suites.

The SPEC HPC2002 suite comprises three benchmarks, each with a small- and
medium-sized data set:

-- SPEC ENV2002 is based on a weather research and forecasting model called
WRF. It has two metrics of performance, SPECenvM2002 and SPECenvS2002.

-- SPEC CHEM2002 is based on a quantum chemistry application called GAMESS;
its performance metrics are SPECchemM2002 and SPECchemS2002.

-- SPEC SEIS2002 represents an industrial application that performs time
and depth migrations used to locate gas and oil deposits. Its performance
metrics are SPECseisM2002 and SPECseisS2002.

SPEC HPC2002 metrics represent the number of successive benchmark runs that
can be completed in a 24-hour period on a system being tested. Results can
be compared for different parallel architectures, shared-memory or
distributed-memory (cluster). This allows users to compare performance
based on full applications across a range of modern high-performance

"SPEC HPC2002 answers the need for standardized benchmarks based on HPC
applications from industry and research using the MPI and OpenMP
standards," says Wesley Jones, SPEC HPG chair. "SPEC's run and reporting
rules, run tools, and established review processes help maintain accurate,
repeatable and consistent benchmark results."

SPEC HPC2002 is available immediately from SPEC for $3,000, with a discount
price of $750 for universities and other non-profit organizations. More
information on SPEC HPC2002 is available on the SPEC web site at or through e-mail at

Subject: Conference in Portugal on Problem Solving Environments

Advanced Environments and Tools for High Performance Computing

EuroConference on Problem Solving Environments and the Information

WHEN: 14 - 19 June 2003 at Albufeira (Algarve), Portugal

Supported by the European Commission, Research DG,
Human Potential Programme, High-Level Scientific Conferences.

There is a clear trend in modelling and simulation technology away
from rigid simulation codes treating a fixed aspect towards
sophisticated problem-solving environments (PSEs). These
environments are widely considered an essential, emerging
technology with high impact across all fields of science and
engineering. PSEs will be especially important to successfully
address all kinds of multidisciplinary phenomena such as
fluid-structure coupling and rapidly developing fields such as
bio-informatics and other application fields where vast amounts of
data need to be managed and processed to discover patterns and
knowledge contained within it. By integrating the latest research
results into easy-to-use environments and utilizing grid computing
infrastructure, PSEs will also help to make them easier to exploit
for larger user communities. The conference program addresses the
state-of-the-art in infrastructure, standards, and core technologies
(i.e. data mining, intelligence, virtual interfaces, grid computing)
for PSEs and reviews PSE developments in health, bio-informatics,
engineering, marketing and finance, environment, and education and

Subject: Postdoctoral Position at Cemagref, France

Postdoctoral position
" Advanced numerical modeling of complex subsurface drained systems "

A postdoctoral position is proposed by two research teams of Cemagref
Institute (, "Drainage and Barrier
Engineering Unit" (DEAN) and "Irrigation Unit" (IRMO). Post-doc position
location would be in Antony (Paris suburb).
DEAN and IRMO have developed several works in 2D, and at the drainage system
scale. However, more sophisticated modeling tools are now necessary to treat
questions related to the impact of drainage systems on the environment. A
3D-modeling approach based on Richards' equation and different type boundary
conditions, including free interfaces, could constitute a relevant tool to
consider this issue. The present postdoctoral position is considered as an
important step in the development of such a tool.
Following steps would be carried out:
(i) specification of the abilities of the available numerical codes to treat
the problem;
(ii) definition of the pre and post processing tools;
(iii) development of the code(s) if necessary;
(iv) definition of a simple generic case study;
(v) verifications of the model and tests of sensibility;
(vi) scientific papers publication.

The candidate should have a PhD in the following disciplines : Modeling in
Hydrology, Hydraulics, Mechanics or similar. A significant experience in
development/testing of the numerical methods for PDE, based on finite
volumes, finite elements or kinetic methods, is strongly recommended.
Particular motivation for realistic modeling would be appreciated.

The position will be for 18 months from winter or spring 2003. The
postdoctoral fellowship is about 1600 euros/months, benefits include basic
health insurance.
Applicants should submit (by e-mail or post):
* a curriculum vitae with list of publications (with some reprints or PhD
thesis included),
* a letter in support to justify the application,
* names and addresses of three references.
