Limited-Preemption Scheduling on Multiprocessors
Bipasa Chattopadhyay, Sanjoy Baruah · 2014
Limited-preemption scheduling of sporadic task systems upon a multiprocessor platform is considered, when inter-processor migration is permitted. A schedulability test is derived by extending a prior schedulability test for fully-preemptive scheduling of sporadic task systems to the above-mentioned platform. We describe how the derived schedulability test can be used as a schedulability test for multiprocessor, multi-GPU systems with busy-waiting. Experimental evaluations are used to show the efficacy of the derived schedulability test in the context of the multiprocessor, multi-GPU system model.
