      abstract     = {The supercomputers maintained by the Jülich Supercomputing
                      Centre (JSC) are run in batch mode and are shared among all
                      active users. Jobs are submitted to the job scheduler, which
                      determines for each job the time of execution. It manages
                      running and waiting jobs, sorts them by a given priority and
                      executes the jobs by fitting them into the current system
                      state. For users it is often difficult to comprehend the job
                      scheduler's algorithm. Thus, a prediction of the future
                      system allocation of currently running and queued jobs is
                      valuable. It helps users to plan job submissions and
                      supports administrators by optimising the system load. This
                      talk summarises the design and implementation of a
                      configurable simulation for various job schedulers. The
                      developed simulation program called JuFo focuses on the job
                      schedulers Loadleveler and Moab as these are the most
                      important batch systems for the supercomputers provided by
                      the JSC. A major design goal is to keep the simulation
                      independent from special job schedulers, which is achieved
                      by the generic configuration of JuFo. Finally, a test
                      framework is developed, which allows for evaluating the
                      accuracy of the generated schedules.},
