摘要：Cross-layer fault-tolerance solutions are the key to effectively and efficiently increase the reliability in future safety-critical real-time systems. Replicated software execution with hardware support for error detection is a cross-layer approach that exploits future many-core platforms to increase reliability without resorting to redundancy in hardware. The performance of such systems, however, strongly depends on the scheduler. Standard schedulers, such as Partitioned~Strict Priority Preemptive (SPP) and Time-Division Multiplexing (TDM)-based ones, although widely employed, provide poor performance in face of replicated execution. In this paper, we propose the replica-aware co-scheduling for mixed-critical systems. Experimental results show schedulability improvements of more than 1.5x when compared to TDM and 6.9x when compared to SPP.
