Olena 1.0 has been completely rewritten since Olena 0.11. This new version is not compatible with the previous ones. It tends to be easier to use and faster to compile and run. We would appreciate any [[1]]/[reports] about this new version.

Olena 1.0 has been successfully tested on GNU/Linux (Debian GNU/Linux 5.0) and Mac OS X v10.5 Leopard.

The Olena platform is Free Software. It is distributed under the conditions of the GNU General Public License (GPL) version 2.


Olena 1.0 is available as source code archives (tarballs).

  • The core C++ library, renamed to Milena, has been rewritten from scratch and features numerous additions over the past releases.
  • Milena uses a simplified version of the SCOOP 2 paradigm (informally called SCOOP 1.5), to improve the speed of compilation and the ease of development while still providing very good run-time performances.
  • A first reimplementation of Swilena featuring Python wrappers for a very small subset of Milena is available. The Swilena Python Shell (sps) allows interactive Olena sessions.
  • A reference documentation including a tutorial and a quick reference guide have been started. They do not cover the whole library yet.
  • Olena includes some demos which use Milena, the core C++ library.
  • Olena has now an official logo.

More information on updates are provided in the NEWS file of the package.
