With the increase in the complexity and number of nodes in large-scale high performance computing (HPC) systems, the probability of applications experiencing failures has increased significantly. As the computational demands of applications that execute on HPC systems increase, projections indicate that applications executing on exascale-sized systems are likely to operate with a mean time between failures (MTBF) of as little as a few minutes. A number of strategies for enabling fault resilience in systems of extreme sizes have been proposed in recent years. However, few studies provide performance comparisons for these resilience techniques.
The research objective of this project is to analyze existing state-of-the-art HPC resilience techniques that are being considered for use in exascale systems.The goal is to explore the behavior of each resilience technique for a diverse set of applications varying in communication behavior and memory use, and design new resilience techniques with better scalability. We aim to examine how resilience techniques behaves as application size scales from what is considered large today through to exascale-sized applications. We further propose to study the performance degradation that a large-scale system experiences from the overhead associated with each resilience technique as well as the application computation needed to continue execution when a failure occurs. We will also examine how application performance on exascale systems can be improved by allowing the system to select the optimal resilience technique to use in an application-specific manner, depending upon each application’s execution characteristics.
