  1. Motivation : The Mean-Time-To-Failure of the systems is decreasing with growing number of cores. Problem will get worse in the future with exascale systems. Algorithm-based fault-tolerance can be alternative method. • Our Goal : Handle fail-stop failures without using any back up node. • Our Approach : • Minimum Data Intersection • Passive Replication • Summarization Fault Tolerant Parallel Data Intensive AlgorithmsMucahidKutlu, GaganAgrawal, Oguz Kurt (Ohio State University) P1 P2 P3 P4 P5 P6 P7 primary 1 2 3 4 5 6 7 8 9 10 11 12 13 14 replica 12 13 1 14 2 3 4 5 6 7 8 9 10 11
