Integration of multiple processing elements on a single chip has lead to parallel execution of applications on the same multicore platform. For these applications, task mapping and scheduling have significant impact on their timing response and energy consumption. However, the on-chip entities executing these tasks of any given application might fail during run-time. Fault tolerance becomes challenging when real-time applications are hosted on such fault prone environment. The complexity of the problem is further magnified in dynamic scenarios when realtime applications can enter or leave the multicore platform at any time instant. In this work, we present a run-time solution to the unified problem of fault tolerant mapping and scheduling for real-time applications. Both the temporal property of the tasks and the timing information of the faults are considered while selecting a suitable fault tolerance strategy, which reduce the communication energy consumption and satisfies deadline for the tasks of executing applications. On comparing with other fault tolerant approaches, the proposed policy shows 23.4% average reduction in communication energy consumption of applications while achieving 32% improved deadline performance. Additionally, the proposed scheme shows reduced fault tolerance overhead in comparison with existing techniques reported in literature. |
