As reported by many recent studies, the mean time between failures of future post-petascale supercomputers is likely to reduce, compared to the current situation. The most popular fault tolerance approach for MPI applications on HPC Platforms relies on coordinated check pointing which raises two major issues: a) global restart wastes energy since all processes are forced to rollback even in the case of a single failure, b) checkpoint coordination may slow down the application execution because… CONTINUE READING
