SimGrid

(see http://simgrid.gforge.inria.fr/ ) is a toolkit that provides core functionalities for the simulation of distributed applications in heterogeneous distributed environments. The specific goal of the project is to facilitate research in the area of distributed and parallel application scheduling on distributed computing platforms ranging from simple network of workstations to Computational Grids.

Perfect simulator

– ${\Psi }^2$ (https://gforge.inria.fr/projects/psi/ ) is a simulation software of markovian models. It be able to simulate discrete and continuous time models to provide a perfect sampling of the stationary distribution or directly a sampling of functional of this distribution by using coupling from the past The simulation kernel is based on the CFTP algorithm, and the internal simulation of transitions on the Aliasing method.

PEPS

– The main objective of PEPS (http://www-id.imag.fr/Logiciels/peps/ ) is to facilitate the solution of large discrete event systems, in situations where classical methods fail. PEPS may be applied to the modelling of computer systems, telecommunication systems, road traffic, or manufacturing systems. Development has continued at INF/UFRGS.

GameSeer

(http://mescal.imag.fr/membres/panayotis.mertikopoulos/publications.html ) is a tool for students and researchers in game theory that uses Mathematica to generate phase portraits for normal form games under a variety of (user-customizable) evolutionary dynamics. The whole point behind GameSeer is to provide a dynamic graphical interface that allows the user to employ Mathematica's vast numerical capabilities from a simple and intuitive front-end. So, even if you've never used Mathematica before, you should be able to generate fully editable and customizable portraits quickly and painlessly.
