PReMAS: Simulator for Resource Management

This paper reports on PReMAS, a simulator used for research on parallel scheduling, processor allocation, and task mapping for systems with rigid batch jobs scheduled with pure space sharing. PReMAS features an object-oriented design that has proven adaptible for a variety of research foci and is easily extendible to incorporate new resource management algorithms. We are making its code public to save others development time and to promote the reproducibility of resource management research. We discuss PReMAS´s design and lessons learned in its development to promote greater discussion of the simulators underlying so much resource management research.
