Subject: Linear algebra software survey request

We are planning to update the survey of freely available software for the
solution of linear algebra problems. The September 2006 version of the survey
can be found at:
The aim is to put in “one place” the source code that is freely available for
solving problems in numerical linear algebra, specifically dense, sparse
direct and iterative systems and sparse iterative eigenvalue problems. Please
send me updates and corrections. I will post a note on the na-digest when the
new list is available.

Subject: Software for solving eigenvalue problems

We are pleased to announce release 2.0 of JADAMILU software package.

JADAMILU is a Fortran 77 program to compute selected eigenvalues and
associated eigenvectors of large scale real symmetric or complex
Hermitian matrices. Generalized eigenvalue problems with positive
definite mass matrix can also be solved. The eigenvalues sought can
either be the smallest ones or those closest to some specified target
inside the spectrum. The software is based on the Jacobi-Davidson
method. Key features are modest memory requirements and robust
convergence to accurate solutions. What makes JADAMILU different from
many other excellent eigenvalue solvers is that it provides automatic
setup of an in-built preconditioner. Moreover, if needed, the
preconditioner is automatically adapted as the computation proceeds.

The package is easy to install (we provide pre-compiled libraries for
most architectures, including Windows based systems), and the driver
routines have be designed to be easy-to-use by non-experts.
If the matrix is sparse and explicitly available, the user can simply
pass it to the program and let JADAMILU compute the desired eigenvalues.
If not, then a crude sparse approximation which may even be diagonal,
can be passed. In the latter case the user only needs to define a routine
that performs matrix-vector products.

New features in JADAMILU_2.0:
- Routines for generalized eigenvalue problems
- Support for complex arithmetic to solve Hermitian (generalized or standard)
eigenvalue problems
- All routines available in double precision, double complex, single precision
and single complex

Subject: New efficient cluster solvers for separable PDE are available

New Intel(R) Cluster Poisson Solver Library (Intel(R) CPSL) is a powerful
tool set for solving separable Partial Differential Equations (PDE). It
offers a set of 2D solvers for Poisson-like problems, as well as an example
of a 3D Poisson solver. Intel(R) CPSL provides an advanced implementation of
the modern algorithms. For more experienced users, Intel(R) CPSL offers
insight into the solvers sufficient to finer tune them for better
performance. The Intel(R) CPSL is currently available only for the Linux*

Intel(R) CPSL offers:
2D Helmholtz solver
2D Poisson solver
2D Laplace solver
Example of a 3D Poisson solver

The solvers employ fast Fourier transforms for solving PDE problems with
separable variables. The main goal for releasing the solvers to the public
is to get feedback on what you do or do not like about them.

Free version of the Intel(R) CPSL can be downloaded from , or from

Subject: libflame: The Complete Reference

We are happy to announce the birth of a user's guide to our libflame
software package. libflame is a dense linear algebra library that has
resulted from the FLAME project. It is a significant step towards a
modern replacement of the classic LAPACK library and can be used as a
substitution for the major routines in that library and/or as an
infrastructure for developing new functionality. While it boasts
performance that rivals or surpasses that of LAPACK, it emphasizes
programmability. libflame also includes prototype routines that allow
matrices to be stored by blocks (even with arbitrary-depth
hierarchies), as well as a runtime system that extracts high-level,
dependency-aware parallelism from major operations on multithreaded
architectures. We believe libflame is also a useful pedagogical tool.

This document, titled "libflame: The Complete Reference", can be
downloaded for free from

Complete instructions on how to download, configure, build, link with
the library can be found in the document, as well as detailed
descriptions of all supported routines.

Comments on the document as well as the library itself are welcomed
and appreciated.

Also, we are pleased to announce that we now support both GNU/Linux and
Microsoft Windows.

Subject: Inverse Problems' special section on testing inversion algorithms

Inverse Problems is pleased to announce that its latest special section, on
testing inversion algorithms against experimental data: 3D targets, is now
freely available online until 12th of March 2009 at

This special section was Guest Edited by Amelie Litman and Lorenzo Crocco and
contains the results of the application of several electromagnetic inverse
scattering methods to the experimental database provided by the Institut
Fresnel, Marseille, France and constituted by three-dimensional dielectric

We are pleased to make the Guest Editors' introduction and the two articles
'Continuing with the Fresnel database: experimental setup and improvements in
3D scattering measurements' by J M Geffrin and P Sabouroux and
'Three-dimensional quantitative microwave imaging from measured data with
multiplicative smoothing and value picking regularization' by Juergen De
Zaeytijd and Ann Franchois featured articles on the journal homepage; to read
them for free visit

We hope you enjoy reading these articles as much as we have.
