Review Paper on Fault Tolerant Scheduling in Multicore System

In this paper, it was discussed about various fault tolerant task scheduling Algorithm for the multicore system based on hardware and software. Blend of triple module redundancy and double module redundancy considering Agricultural vulnerability factor other than EDF and LLF scheduling algorithms were used to create hardware-based algorithm. Most of the real-time systems used shared memory as dominant part. Low overhead software-based fault tolerance approach could be implemented at user space level so that it did not require any changes at an application level. Redundant multithread processes were used which could detect soft recover from the errors and could recover from them giving low overhead, fast error mechanism recovery, and detection. The overhead incurred by this method ranged from 0 to 8% for selected benchmarks. Another system used for scheduling approach in real-time systems was hybrid scheduling. Dynamic fault tolerating scheduling gave high feasibility where task critically was used to select the fault recovery method type in order to tolerate maximum no. of faults
