Development of Application-level Fault Tolerance in a Real-time Benchmark

As multiprocessor systems become more complex their reliability will need to increase as well In this paper we propose a novel technique which is applicable to a wide variety of distributed real time systems especially those exhibiting data parallelism We assert that for high reliability a combination of system level fault tolerance and application level fault tolerance works best In many systems application level fault tolerance can be used to bridge the gap when system level fault tolerance alone does not provide the required reliability We exemplify this with the RTHT target tracking benchmark
