ABSTRACT:
Recent trends in high-performance computing point towards extremely large machines with millions of processing, storage, and networking elements. Unfortunately, the reliability of these machines is inversely proportional to their size, resulting in a system-wide mean-time-between-failures (MTBF) ranging from a few days to a few hours. As such, for long-running applications, the ability to efficiently recover from frequent failures is essential. We have developed three different fault tolerant techniques to compensate for the high failure rates in HPC systems. These techniques employ redundant communication, VM-based checkpointing and selective restart to provide applications with a high-degree of fault tolerance.
