Academic Page


Arnaud Legrand is the leader of the POLARIS team. He is a CNRS research scientist at the LIG. His research targets the management (mostly from an algorithmic point of view, i.e., scheduling, load balancing, fairness, game theory….) and performance evaluation (in particular through simulation, visualization, statistical analysis, …) of large scale distributed computing infrastructures such as clusters, grids, desktop grids, volunteer computing platforms, clouds,… when used for scientific computing. He is one of the main developers of the SimGrid project, a simulation toolkit for building simulators of distributed applications (originally designed for scheduling algorithm evaluation purposes) developed in collaboration with Henri Casanova, Martin Quinson and Frédéric Suter.
