Context Switching and Scheduling in C--

Shawn Hsiao and Olushola Olateju

We present a framework for preemptive threads in C--. We describe the front- and back-end runtime system support requirements of our model. Our model extends the current C-- framework with new services. In particular, we suggest two extensions to the back-end runtime interface: a mechanism for saving the state of a suspended execution and a revised mechanism for resuming the state of a suspended execution. We demonstrate the plausibility of our model for the simplest case and conjecture on its extensibility to the general case.
