A survey of fault tolerance approaches on different architecture levels
Lukas Osinski, Tobias Langer, Juergen Mottok · 2017
In the recent years the development trends for computing platforms moved to multicore systems. Associated with this trend, feature sizes decreased with each new hardware generation and consequently led to a rise of transient and permanent error frequency in memory and CPUs. In this context, researchers presented several approaches which exploit the inherent redundancy of multicore platforms to provide fault tolerance. We present a discussion of fault tolerance approaches based on redundancy at different levels of architecture regarding theirsphereofreplication,performanceaswellaserrordetection and recovery capability.
