Supercomputers have seen an exponential increase in their size in the last two decades. Such a high growth rate is expected to take us to exascale in the timeframe 2018-2022. But, to bring a productive exascale environment about, it is necessary to focus on several key challenges. One of those challenges is fault tolerance. Machines at extreme scale will experience frequent failures and will require...
Although many details of an eventual Exascale machine remain unknown, we can safely make a couple of assumptions. Exascale machines will be composed of multicore nodes and will experience frequent failures. The latter means that effective resilience support is imperative to make Exascale machines usable. The former opens up opportunities for exploring new alternatives to provide resilience support...
