摘要：

A new Slurm simulator compatible with the latest Slurm version has been produced. It was constructed by systematically transforming the Slurm code step by step to maintain the proper scheduler output realization while speeding up simulation time. To test this simulator, a container-based Virtual Cluster was generated which fully mimicked a production HPC cluster. As for all Slurm simulators, the realization is a stochastic process dependent on the computational hardware. Under favorable conditions the simulator is able to approximate the actual Slurm scheduling realization. The simulation fidelity is sufficient to use the simulator for its main function, that is, to test Slurm parameter configurations without having to experiment on full production systems.
