Subject: Complex Biconjugate Gradient

I am looking for a complex (non Hermitian) Biconjugate gradient routine
for dense matrices from BEM. I am wondering whether someone on NA-net
modified templates for complex matrices.

Subject: Seeking Nonlinear Systems with Singular Jacobian at the Solution

Dear NA-NETters,

I am testing some new Newton-type techniques for solving a nonlinear

F(x)=0, F : D \subseteq R^n --> R^n,

when the Jacobian is singular at (and possible near) an isolated solution x*.
I am seeking relevant examples of such systems (i.e., when F comes from
practical problems, n is large, etc.), but with the restriction that one
knows the Jacobian F'(x*) (hopefully, the solution x* need not be known).
Thanks in advance.

Subject: Release of PETSc 2.1.0

Portable, Extensible Toolkit for Scientific Computation (PETSc)

We are pleased to announce the release of the PETSc 2.1.0 parallel
software libraries for the implicit solution of PDEs and related
problems. New features of this release include:

(1) a parallel, sparse, symmetric matrix storage format, this includes
support for sequential Cholesky and ICC(k)
(2) a complete framework for parallel linear multigrid on
structured grids (for both linear and nonlinear problems)
(3) Mandel's balancing Neumann-Neumann method for scalar PDEs
(4) an interface to the Tufo-Fischer highly efficient parallel
coarse grid direct solver library tfs
(5) support for managing "composite" vectors consisting of
subvectors that represent conceptually different quantities
(for example, constraints or Lagrange multipliers)
(6) more complete hypertext documentation, including links to
hypertext versions of all the examples and source code

As always, please send bug reports, questions, and requests for new
features to

Thanks for your continued support.

The PETSc developers,
Satish, Kris, Bill, Dinesh, Lois, and Barry

Why 2.1.0? PETSc 2.1.0 represents the cumulation of several years of
effort to convert PETSc 2.0 to use dynamic libraries. Dynamic
libraries allow users to delay until runtime the choices of what
algorithms and data structures to run without generating enormous

Subject: KNITRO, New Optimization Package

KNITRO, a new package for solving large constrained optimization
problems, has just been released. See
for instructions on how to obtain a copy.

Subject: New Book, Performance Optimization of Numerically Intensive Codes

My collaborator Stefan Goedecker and I are very pleased to announce the
recent publication of our book "Performance optimization of numerically
intensive codes" published by SIAM.

The book offers a comprehensive treatment of important aspects in achieving
high-performance in numerical computations on modern computer
architectures, both serial and parallel.

We anticipate that our book will be useful to all practitioners of
computational science, scientists, engineers and students,. Also, it could
be used as basic material for courses in computer and computational
sciences, including classes in high-performance computing.

We are very interested in your feedback, please feel free to send me your

Subject: Postdoctoral Position at the University of Massachusetts

Applications are invited for a Post-doctoral position in the Department of
Mechanical Engineering at the University of Massachusetts, Amherst.

The Laboratory for Theoretical and Computational Fluid Dynamics has
funds from the Office of Naval Research to support the development of
a kinetic model of turbulence based on eddy collisions. This innovative
project requires the numerical solution of probability distribution function
transport equations on massively parallel computers. A strong analytical
and programming background and experience with lattice-Boltzmann
methods, turbulence modeling, or pdf equations is highly desired.
Salary and benefits will be commensurate with the level of experience.

Interested applicants should e-mail a curriculum vitae to Prof. Blair Perot
at or postal mail to:

Professor Blair Perot

Subject: Research Position at Uppsala University, Sweden

at the Department of Scientific Computing,
Uppsala University, Uppsala, Sweden

Applications are invited for a position as researcher (forskarassistent)
at the Department of Scientific Computing, Uppsala University. The
position is limited to four years. The duties are research, supervision
of PhD-students and teaching. The teaching load is at most 25 per cent of
full time. The candidate must hold a doctoral degree less than
five years old. Ability to teach in Swedish or English is a requirement.

The main subjects of research at the department are numerical solution
of partial differential equations in different application areas like
fluid mechanics, electromagnetics and acoustics, and development of
algorithms and software for high performance computers. More information
is available at

The main criteria for selection among the candidates are scientific
and pedagogical skills with emphasis on the former. When evaluating the
scientific skills, merits in numerical solution of differential equations,
numerical linear algebra, numerical optimization, or development of
algorithms and software for high performance computers are important.

According to the equal opportunity policy of the university, applications
from women are especially invited.

The application should be written in English and has to include two copies of
1. a curriculum vitae and copies of degrees obtained and other documents of
relevance, all to be signed and witnessed
2. a short account of the scientific and teaching experience
3. a list of scientific publications
and one copy of each of the publications according to the above list.

The application should be sent to: Uppsala University, The Registrar,
UFV-PA 2001/1275, P O Box 256, SE-75105 Uppsala, Sweden, or by
fax +46 18 4712000, no later than April 23, 2001. If an application
is sent by fax, the signed application should follow by mail as soon
