A "17 millions dark matter particles movies":http://www.cines.fr/IMG/avi/dm-final2.avi, rendered with glnemo2, has been done at French supercomputer CINES . Ramses code has been used to run the simulation and glnemo2 to render the movie.
Simulation initial conditions have been run by Emmanuel Nezri and Pol Mollitor.

Unsio beta test is open. A lot of bugs have been fixed and wiki has been improved with a complete documentation about howto develop project using unsio from fortran and c/c++ language.

Unsio is a dedicated package for input/output file operation on Nbody simulation data file.

The purpose is to provide a universal API to read and/or write your Nbody simulation data in unique way, whatever
the simulation file format.

Stay tuned, more information will follow.....

Glnemo2 has been accepted has a visualisation tool at the French super computing center "CINES":http://www.cines.fr/.

Glnemo2 is available from their visualisation server platform.
