We consider the \supertask" approach, proposed by Moir and Ramamurthy at RTSS '99 as means for supporting non-migratory tasks in Pfair-scheduled systems. In this approach, tasks bound to the same processor are combined into a single supertask, which is scheduled as an ordinary Pfair task; when a supertask is scheduled, one of its component tasks is selected for execution. Unfortunately, while Moir and Ramamurthy's paper suggests that supertasking is a promising approach, counterexamples… CONTINUE READING
