What is Batsim?

Batsim is a scientific simulator to analyze batch schedulers. Batch schedulers — or Resource and Jobs Management Systems, RJMSs — are systems that manage resources in large-scale computing centers, notably by scheduling and placing jobs.

Batsim doesn't take scheduling decisions about when and where the jobs must execute. Instead it delegates these choices to a decision process (typically your scheduler).
