**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

Modeling.

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.

Matrix Market (Version 2.0)

(http://math.nist.gov/MatrixMarket)

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

or http://www.mcs.anl.gov/petsc/petsc.html.

Announce

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

discretizations,

* large systems of (sparse) nonlinear or linear equations, or

unconstrained minimization

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.

MATHEMATICS OF HIGH-PERFORMANCE COMPUTING

September 1996 -- June 1997

Organizing Comittee:

Petter E. Bjorstad (University of Bergen),

Mitchell Luskin (University of Minnesota),

Dianne O'Leary (University of Maryland),

Robert Schreiber (Hewlett-Packard),

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.

**Subject: Position at CWI Amsterdam/Leiden University**

Position at CWI Amsterdam/Leiden University

The Centre of Mathematics and Computer Science (CWI) Amsterdam

and the Mathematical Institute of Leiden University are cooperating

in research on parallel algorithms for factoring large numbers.

In this project a position is vacant for a

JUNIOR RESEARCHER

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.

Salary will be Dfl. 2.144 in the first year, rising to Dfl. 3.775

in the fourth year. Women and candidates coming from one of the member

states of the European Union are particularly asked to apply.

For more information, contact Herman te Riele at CWI Amsterdam

(tel. +31 20 5924106, email herman@cwi.nl).

Applicants are requested to send their application letter with curriculum

vitae, and two letters of recommendation (arranged to be sent) within

three weeks after this announcement to Dr. H.J.J. te Riele

at CWI, Kruislaan 413, 1098 SJ Amsterdam, The Netherlands.
