Fault-tolerance for large parallel systems

This PhD thesis of Slim Bouguerra [1] studied fault-tolerance issues for large parallel systems. We revisited, via a formal proof, the old well-known result which states that the optimal policy for exponential failure law is to put the check-points at periodic moments. We proposed new algorithms to handle check-points for any law in the input and variable check-point costs (JPDC paper).
