**Subject: Complex Biconjugate Gradient**

Hello,

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

system

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)

http://www.mcs.anl.gov/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 petsc-maint@mcs.anl.gov.

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

executables.

KNITRO, a new package for solving large constrained optimization

problems, has just been released. See

http://www.ece.nwu.edu/~nocedal/knitro/kindex.htm

for instructions on how to obtain a copy.

Knitro is also available through NEOS:

http://www-neos.mcs.anl.gov/neos/solvers/NCO:KNITRO-AMPL/

KNITRO implements a novel interior point method for nonlinear

programming. It is effective, and recommended, for small or large

problems, with or without constraints.

**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

comments and observations.

The Institute of Computer Science, University of Innsbruck, Austria,

invites applications for 6 faculty positions at the Full Professor

level in

Computer Science

In Fall 2001 the University of Innsbruck will start a new center of

computer science with bachelor, master and Ph.D. programs, several

research groups and intensive co-operations with industry. The

University is seeking applicants from all fields of Computer Science

with a strong background in research and teaching. Contributions to

both undergraduate and graduate teaching are expected, and the

ability to use English as a working language is a requirement.

The City of Innsbruck, which hosted the olympic winter games twice,

is located in the beautiful surroundings of the Tyrolean Alps. The

combination of the Alpine environment and the urban life in this

historically grown town provides a high quality of living. The

university has a long tradition dating back to the 16th century,

and, with seven schools (Theology, Law, Economics and Social

Sciences, Medicine, Humanities, Natural Sciences, Civil Engineering

and Architecture), it offers a wide spectrum of research and teaching

activities and interesting opportunities for interdisciplinary

collaboration. Besides, the Country of Tyrol strongly supports

various initiatives in the IT domain. It is planned to found a Center

of Information and Communication Technology as a forum for tight

interactions between the University of Innsbruck, the University

of Applied Sciences, and industrial partners.

Applicants must

a. have an academic degree in an appropriate field and at the

appropriate level,

b. prove their research and teaching capabilities (equivalence to

Austrian "venia docendi" certificate),

c. have the necessary pedagogical and didactic skills,

d. be capable of managing a university institution,

e. demonstrate that their research is internationally acknowledged

**Subject: Research Positions at Lawrence Livermore National Laboratory**

Postdoctoral and career positions are available in the Center for Applied

Scientific Computing (CASC) at Lawrence Livermore National Laboratory

(LLNL). The Center for Applied Scientific Computing conducts collaborative

scientific investigations that require the power of high performance

computers and the efficiency of modern computational methods. Our research

and development activities are driven by scientific and engineering

applications at LLNL that require advanced computational technologies. The

Center performs research and development primarily in the areas of high

performance computing, computational physics, numerical mathematics, and

computer science. Researchers at CASC have access to some of the most

sophisticated computing facilities, including two massively parallel IBM

SP2's (ASCI platforms) and several Compaq Alpha clusters.

The available positions

(http://www.llnl.gov/CASC/jobs/sci_comput_apps.html) are in several efforts

in application simulations jointly conducted by engineers, physicists,

computer scientists and numerical analysts:First-principles molecular

dynamics (electronic structure calculation methods), Radiation and neutron

transport, Adaptive mesh refinement and applications, Fracture dynamics

simulations, Computational electromagnetism, Laser-plasma interaction

simulations, High performance preconditioners and Nonlinear solvers.

Required basic skills are knowledge of the physical processes involved in

the respective project or related field, and/or in applicable numerical

methods. Working knowledge of C/C++ and/or MPI is highly regarded in most

of the cases.

Positions are available immediately. Postdoctoral positions are for a

period of one year, renewable to three years. Applicants must have or soon

expect to receive a PhD in applied mathematics, computer science, physics

or other relevant background in computational methods. There are no

citizenship restrictions on the positions.

Interested applicants can contact Xabier Garaizar (garaizar@llnl.gov) for

further inquiry, or can directly send letters of reference, a curriculum

vitae and a statement of research interests to: Xabier Garaizar, Center for
