DUNE ISTL 1.0 - Release notes

Changes to Previous Releases

Since this is the very first release there are no changes that we can list. But here is a short list of features that the DUNE 1.0 release provides.

• Linear Algebra

  DUNE contains ISTL (the Iterative Solver Template Library) for powerful linear algebra. The main features are:

  • Abstractions for block matrices (e.g. compressed row storage and block diagonal) and block vectors
  • Block structure arbitrarily nestable
  • High performance through generic programming
  • Expression templates for BLAS1 routines
  • Several standard solvers

Tested Platforms

The DUNE core developers have tested DUNE on the following platforms.

• Debian Linux Sarge and Etch, using mpich/lam and gcc (3.4, 4.0, 4.1)
• Gentoo Linux, using openmpi/mpich and gcc (3.4, 4.0, 4.1)
• HP XC Version 3.0/SFS 2.1 using gcc (3.4 ,4.0)
• SuSE Linux 10.x using gcc

We have also gotten reports of successful installations on various flavours of Mac OSX.

Known Issues

Here is an (incomplete) list of things that we know not to work in DUNE 1.0.

Issues Applying to all modules

• config.h is needed as first include in all applications
• Out of source builds are not possible right now.
• The build system only recognizes dependendies on a fixed set of known modules. Besides the core Dune modules these are dune-disc, dune-fem, and dune-subgrid.
• The build system does not work with Solaris make. Please use GNU make instead.
• DUNE doesn't install on Windows platforms, not even using CygWin.
• So far DUNE has not been developed with thread-safety in mind, and you're probably bound for trouble if you try multi-threaded code.

dune-istl

• Sometimes old c-headers are still used (-> Not fully standard compliant)
• Output still uses C-style printf
• Smoothers of AMG do not support block level.

Not to mention all the open bugs there are!
