| Summary: | Scheduling on multicores is a much harder problem than those studied under single processor scheduling theories, largely because of the inherent non-parallelism in workload tasks. Although a multicore platform may execute different tasks from a workload at the same time, it is typically not allowed to execute the same task on more than one core simultaneously. This project plans to research multiprocessor frameworks and platforms to tackle these issues. One important concept is the notion of virtual processors, which allow to use a three-step scheduling strategy: partitioning of workload tasks and assigning virtual processors to each partition, scheduling of tasks on virtual processors within each cluster, and scheduling of virtual processors on the physical cores. Another important concept is the notion of pJobs, which allow tasks to be executed in parallel in the physical cores, increasing the potential parallelism of applications. The project will also research into architectures and platforms for supporting these concepts, and the underlying resource sharing paradigms. |
