Lazy checkpoint coordination for bounding rollback propagation
Y.-M. Wang, W.K. Fuchs · 2002
The technique of lazy checkpoint coordination, which preserves process autonomy while employing communication-induced checkpoint coordination for bounding rollback propagation is proposed. The notion of laziness is introduced to control the coordination frequency and allow a flexible tradeoff between the cost of checkpoint coordination and the average rollback distance. Worst-case overhead analysis provides a means for estimating the extra checkpoint overhead. Communication trace-driven simulation for several parallel programs is used to evaluate the benefits of the proposed scheme.>
