Systems and methods provide a high-level language for generation of a scheduling specification based on a scheduling policy, and synthesis of scheduler based on the scheduling specification. The systems and methods can permit the use of more sophisticated scheduling strategies than those afforded by conventional systems, without requiring the programmer to write explicitly parallel code. In certain embodiments, synthesis of the scheduler includes implementation of at least one rule related to the scheduling specification through definition of one or more workset objects that are concurrent, a workset object of the one or more workset objects having an addition method, a first poll method, and a second poll method. Such poll methods extend the operability of sequential poll methods. The one or more worksets satisfy a condition for correctness that is less stringent than conventional conditions for correctness.
