This paper contributes an automatic and transparent mechanism for proactive FT for arbitrary MPI applications. It leverages virtualization techniques combined ...
A proactive fault tolerance system, as the name implies, should provide two mechanisms, namely one for proactive decision mak- ing and another to address load ...
Current techniques to tolerate faults focus on reac- tive schemes to recover from faults and generally rely on a checkpoint/restart mechanism. Yet, in today's ...
