Constraints on the Use of Executors in Real-time Systems

Previous work proposed the inclusion of parallelism in Ada to improve the use of multicore processors. This work proposed a model of Tasklets to carry the expressions of parallelism, and introduced the notion of executors to map the execution of Tasklets on hardware. In developing the model, a number of choices arise that effect how well the model will accommodate real-time systems. These choices become constraints which are examined and reasonable choices proposed for adoption in Ada.
