      SimGrid 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.
