Subject: P. J. Paes-Leme
Last month the Computational and Applied Mathematics Brazilian
community lost one of its leaders, PJ Paes-Leme. After a 12 year fight against
a steady disease, PJ passed away on Sep 24, at the age of 48. During that
struggle, he never stopped to make personal contributions to his country
scientific achievements nor to carry out research in different areas of
applications, having deepened colaborations with many groups from abroad.
A student of J.Glimm's in the 70's, at Courant Institute,
PJ came back to his alma-mater, the Catholic University of Rio de Janeiro,
PUC-RJ, with the aim of establishing there a strong group in Applied Math.
His efforts added to the other few local groups that were working towards the
same goal and have helped to build nowadays flourishing of this area in Brazil.
His researches broad span of interests included Quantum Field Theory,
Bio-Math, Pollution flows and, mainly, Oil Flow in Porous Media, where his main
contributions have appeared. For more than one decade he has developed a strong
collaboration with J.Douglas, Jr. and many of his coworkers, first in
Chicago, then in Purdue, having looked closely to flows in fractured media, a
subject suggested by a R&D project he has helped to carry out for Petrobras,
the Brazilian state-owned oil company.
He was the President of SBMAC - Brazilian Society for Computational
and Applied Math - from '85 to '87, but before and after that period he has
always brought important contributions to the community, the most important of
which was certainly his sharing of the chores of the Editorial Board of
"Computational and Applied Mathematics", the Society main publication.
During the recent years his full strength was drawn to the Polytechnic
Institute of Rio de Janeiro - IPRJ -, in Nova Friburgo, as its Chairman,
having worked hardly to establish a interdisciplinary program in Computational
He had always a very human insight towards people around himself -
students, researchers, teachers, fellow workers no matter their background -,
and he always passed along a lot of himself, of his experience, of his efforts.
His former colleagues mourn him and are thankful for having met him.

Subject: Version 2.0 of Matrix Market
Matrix Market (Version 2.0)
We are pleased to announce a major release of the Matrix Market -- a
visual database of matrix test data for use in comparative studies of
algorithms. Version 2.0 includes a new interface, more matrices, a
new file format, additional diagnostic data and matrix statistics,
spectral portraits, and automated submission forms for contributing
new matrices. For more details, see the "What's New" link under the
Matrix Market home page.
The standard features are still there: using the search interface,
one can request matrices with particular attributes, such as
"symmetric eigenvalue problems larger than 500x500" or "matrices from
structural engineering applications". Once a particular matrix is
found, one can view its sparsity pattern at various levels of detail,
and review other pertinent data before downloading.
The original Matrix Market has already seen over 4,000 downloads of
its home page and over 12,000 matrix files retrieved since its
initial announcement in February. Thanks to all who have used and
contributed to the Matrix Market!
(*) Matrix Market 2.0 was designed and developed by by R. Boisvert,
R. Pozo, and K. Remington (National Institute of Standards and
Technology). We thank Jack Dongarra, Richard Barrett, Iain Duff, John
Lewis, Roger Grimes, Yousef Saad, Alan McCoy, Vincent Toumazou, and
Valerie Fraysse for their help.

Subject: Release of PETSc 2.0 software
Portable, Extensible Toolkit for Scientific Computation (PETSc)
We are pleased to announce a public release of PETSc 2.0.
PETSc provides many tools for the parallel (and uniprocessor),
numerical solution of PDEs that require solving large-scale, sparse
nonlinear systems of equations. PETSc includes nonlinear and linear
equation solvers that employ a variety of Newton techniques and Krylov
subspace methods. In addition, PETSc provides several parallel sparse
matrix formats, including compressed row, block compressed row, and
block diagonal storage.
PETSc is fully usable from Fortran, C and C++, and runs portably on
on most UNIX systems. PETSc uses MPI for all parallel communication.
One of the unique features of PETSc is that it enables the
application programmer to easily and efficiently assemble parallel
vectors and sparse matrices. Users can create complete application
programs for the parallel solution of nonlinear PDEs without writing
much explicit message-passing code themselves.
In addition, PETSc is designed to facilitate extensibility. Thus,
users can incorporate customized solvers and data structures when
using the package.
Information regarding PETSc as well as the complete software
distribution can be obtained from ftp://info.mcs.anl.gov/pub/petsc

Bring-Your-Own-Code Workshops on the Portable Parallel Solution of PDEs
December 11-13, 1996
ICASE, NASA Langley Research Center, Hampton VA
April 14-16, 1997
Cornell Theory Center, Cornell University, Ithaca, NY
The workshops are designed for computational engineers and scientists
with interests in distributed computation for large-scale problems in
PDEs. Participants will be introduced to PETSc, the Portable,
Extensible Toolkit for Scientific Computation. The workshops will
consist of a day of presentations by PETSc developers and users, and
two days of "hands-on" coaching in the port to parallel machines of
codes brought by participants.
If your computational problems involve
* numerical solution of PDEs,
* implicit or semi-implicit solution methods for stencil-type
* large systems of (sparse) nonlinear or linear equations, or
and you are
* currently developing parallel code,
* want to develop parallel code, or
* wish to solve larger problems than you currently can solve,
then these workshops may be for you.
Both workshops will be limited in size, with preference going to
groups whose applications seem most immediately suited to and
supported by PETSc.
Because of its location within the LaRC security area, the ICASE/LaRC
workshop is limited to U.S. citizens and permanent residents.

and Ridgway Scott (University of Houston)
Co-Sponsors: Minnesota Supercomputer Institute and the Geometry Center
Winter Program (January -- March, 1997): Molecular Modeling and HPC
Workshop: Molecular Structure: Dynamics, Geometry and Topology
January 20--24, 1997. Organizers: Ridgway Scott (Univ. of Houston)
and Tamar Schlick (Courant Institute, NYU)
This workshop will focus on the design of macromolecules to perform
biological or industrial functions. Although the structure of
macromolecules can often be described as a linear sequence of
bonded atoms, the three-dimensional structure and resulting
function remain elusive. The quantum-mechanical models involved
can appear formidable; nonetheless, new approaches, ranging from
topology, geometry, mechanics, Monte Carlo methods, and even
artificial intelligence, are becoming feasible.
Workshop: Structured Adaptive Mesh Refinement Grid Methods
March 12--13, 1997. Organizers: Scott B. Baden (UCSD),
Nikos P. Chrisochoides (Cornell University), Dennis Gannon
(Indiana University) and Mike Norman (NCSA, UIUC)
This workshop will bring together experts in applications, numerical
methods, and software development for SAMR. Applications include
compressible flows, cosmology, and electronic structures
arising in local spin-density calculations.
Workshop: Computational Radiology and Imaging: Therapy and Diagnostics
March 17--21, 1997. Organizers: Christoph Borgers (Tufts Univ.) and
Frank Natterer (Univ. of Munster, Germany)
Radiation is used in medicine for both diagnostics and therapy. These
applications lead to hard computational and mathematical problems.
As an example, Boltzmann transport equations underlie the modeling
of optical tomography and radiotherapy planning. Typically,
inverse problems are the ones of ultimate interest, but even the
forward problems are often quite difficult computationally. This
interdisciplinary workshop will include a substantial number
of expository talks aimed at non-specialists.
Tutorial: Rational Drug Design
April 3-4, 1997. Speaker: David Ferguson (University of Minnesota)
Workshop: Rational Drug Design
April 7-11, 1997. Organizers: Jeff Blaney (Chiron), Tony Hopfinger
(Univ. of Illinois-Chicago), Jeffrey Howe (Upjohn Company).
Sponsored jointly with Minnesota Supercomputer Institute
Computational approaches for drug discovery and optimization have
proven effective in many recent research programs. This workshop will
cover 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. Mathematical topics will include graph theory
and topology, non-linear multidimensional optimization, the processing and
representation of information obtained from simulation studies, global
optimization and search strategies, as well as performance enhancement
through parallel computing architectures.

In this project a position is vacant for a
His/her task will be to study the ``Number Field Sieve'' factoring
algorithm (NFS) and improve the efficiency of an existing NFS code
which was developed at CWI and Oregon State University.
This efficiency improvement is pursued by revising some of the
algorithmic steps in NFS, decreasing the huge amount of central memory
required at some stages, and using parallel computers.
The existing code played a crucial role in the establishment of a new
world record (in April 1996) by the factorization of RSA-130.
The project is intended to be concluded after four years with a
Doctoral Thesis and an Academic Promotion. Most of the time it will be
carried out at CWI Amsterdam.
Candidates, preferably not older than 26 years, have finished their
Master's Degree with specialization in algebraic number theory.
Affinity and practical experience with computers is an advantage.
Appointment will be in temporary service with NWO, the Netherlands
Organization of Scientific Research, for at most four years.
