Given the projected higher variations in the availability of computational resources, adaptive static schedules have been developed to attain high-speed execution reconfiguration with no reliance on any runtime rescheduling decisions. These schedules are able to deliver predictable execution despite the increased levels of device unreliability in future multicore systems. Yet the associated runtime reconfiguration overhead is largely determined by the underlying system topology. Fully connected architectures, although they can effectively hide the overhead in execution migration, become infeasible as the core count grows to hundreds in the near future.
