Subject: The cost of textbooks
As a parent of a college student (with two more to go), I have become
painfully aware of the cost of textbooks. As a result, I have been
contemplating the irony that our community is obsessed with providing
Open Source code, but thinks nothing of producing textbooks that cost
a mint. I point to a popular undergraduate linear algebra text that
is in its nth edition that now costs close to $170, without naming it
by name. Even texts published by SIAM are in the $70+ range.
We are considering self-publishing our next book through
www.lulu.com, which means that a 200 page book will cost the consumer
somewhere in the $10-$15 range. This is close to the cost of
copying it or printing it on a laser printer, but the book will be a
paperback and will have an ISBN numbers.
I look forward to a healthy discussion on this. In particular, if
you have experience with self-publishing, please share that experience!

Subject: Scotch 5.0.4 is out - for graph and mesh/hypergraph partitioning and more
We announce the release, as libre/free software, of revision 5.0.4 of the
SCOTCH and PT-SCOTCH software package and library for graph and
mesh/hypergraph partitioning, static mapping, and sequential and parallel
sparse matrix block ordering.
Revision 5.0.4 provides several new features :
- a new banded diffusion partitioning method is now included in the default
partitioning and mapping strategy. It provides better partitions than the
classical Kernighan-Lin or Fiduccia-Mattheyses methods, with much smoother
boundaries.
- a full-featured ParMeTiS ordering compatibility library which allows users
who are using the parallel graph ordering capabilities of ParMeTiS to try
PT-Scotch without having to modify their source code at all. An improved
interface is also provided to access the distributed elimination/separator
tree structure.
- a new algorithmically-defined weighted complete graph target architecture,
for simply computing partitions of different relative weights.
SCOTCH is a project carried out at the Laboratoire Bordelais de Recherche en
Informatique (LaBRI) of the Universite Bordeaux I.
It is part of project ScAlApplix of INRIA Bordeaux Sud-Ouest. Its goal is to
apply graph theory, with a ``divide and conquer'' approach, to scientific
computing problems such as graph partitioning, static mapping, and sparse
matrix ordering.
Scotch can be freely downloaded, under the terms of the CeCILL-C license.
To ease the development, diffusion, and circulation of information regarding
the SCOTCH project, most of its resources are now hosted on the InriaGforge
platform provided by INRIA. Please refer to the SCOTCH web page at :
http://www.labri.fr/~pelegrin/scotch/
for more information. People interested in the SCOTCH project are welcome to
subscribe to the "scotch-announces" mailing list at :

Subject: Release of Distributed and Unified Numerics Environment (DUNE) 1.0
We are pleased to announce the release of Version 1.0 of the
"Distributed and Unified Numerics Environment" (DUNE).
DUNE is a modular toolbox for solving partial differential equations
(PDEs) with grid-based methods. It supports the easy implementation of
methods like Finite Elements (FE), Finite Volumes (FV), and also
Finite Differences (FD). The underlying idea of DUNE is to create slim
interfaces allowing an efficient use of legacy and/or new
libraries. These goals are achieved, using generic programming
techniques.
DUNE is free software licensed under the GPL (version 2) with a
so-called "runtime exception". This license is similar to the one
under which the libstdc++ libraries are distributed. Thus it is
possible to use DUNE even in proprietary software.
The framework consists of a number of modules which are downloadable
as separate packages.
For further information, have a look at our website
http://www.dune-project.org or contact the mailing list
dune@dune-project.org.
