hsSim: an Extensible Interoperable Object-Oriented n-Level Hierarchical Scheduling Simulator

Hierarchical scheduling is a recent real-time scheduling topic. It is used to obtain temporal interference isolation in various scenarios, such as scheduling soft real-time aperiodic tasks along with hard real-time periodic tasks, and in mixed-criticality scenarios. Most theory and practice focuses on two-level hierarchies, with a root (global) scheduler managing resource contention by partitions (or scheduling servers), and a local scheduler in each partition/server to schedule the respective tasks. hsSim is an object-oriented hierarchical scheduling simulator supporting an arbitrary number of levels. With the goal of openness, extensibility and interoperability in mind, due care was put into the design, applying known design patterns where deemed advantageous.
