The next generation of supercomputers will break the exascale barrier. Soon we will have
systems capable of at least one quintillion (billion billion) floating-point operations per …

Deduplication is a storage saving technique that is highly successful in enterprise backup
environments. On a file system, a single data block might be stored multiple times across …

Many tools and techniques have been developed to address specific aspects of interacting
in a virtual world. Few have been designed with an architecture that allows large numbers of …

Application resilience is a key challenge that must be addressed in order to realize the
exascale vision. Process/node failures, an important class of failures, are typically handled …

The scale of high performance computing (HPC) systems is exponentially growing,
potentially causing prohibitive shrinkage of mean time between failures (MTBF) while the …

While periodic checkpointing has been an important mechanism for tolerating faults in high-
performance computing (HPC) systems, it is cost-prohibitive as the HPC system approaches …

Today's scientific high-performance computing applications and advanced instruments are
producing vast volumes of data across a wide range of domains, which impose a serious …

Checkpoint restart plays an important role in high-performance computing (HPC)
applications, allowing simulation runtime to extend beyond a single job allocation and …

Checkpoint/Restart is an indispensable fault tolerance technique commonly used by high-
performance computing applications that run continuously for hours or days at a time …

As the amount of data produced by HPC applications reaches the exabyte range,
compression techniques are often adopted to reduce the checkpoint time and volume. Since …
