An Examination of the Impact of Failure Distribution on Coordinated Checkpoint/Restart
Scott Levy, Kurt Brian Ferreira · 2016
Fault tolerance is a key challenge to building the first exa\-scale system. To understand the potential impacts of failures on next-generation systems, significant effort has been devoted to collecting, characterizing and analyzing failures on current systems. These studies require large volumes of data and complex analysis. Because the occurrence of failures in large-scale systems is unpredictable, failures are commonly modeled as a stochastic process. Failure data from current systems is examined in an attempt to identify the underlying probability distribution and its statistical properties.
