The Slurm Workload Simulator’s aim is to provide a means of executing a set of jobs, a workload, in the Slurm system without executing actual programs. The idea is to see how Slurm handles and schedules various workloads under different configurations. For instance, an administrator may be interested to know how a job of a given size from a particular group will get scheduled given the current workload on that system. He would be able to set up a simulator environment and with a workload representing that of the real system plus the hypothetical job, he could submit it to the simulator and see the working of Slurm, in this simulated environment, in faster than real-time.
