Faults have become the norm rather than the exception for high-end computing clusters.
Exacerbating this situation, some of these faults remain undetected, manifesting themselves …

Today's largest High Performance Computing (HPC) systems exceed one Petaflops (10^ 15)
floating point operations per second) and exascale systems are projected within seven …

With the scaling up of high-performance computing systems in recent years, their reliability
has been descending continuously. Therefore, system resilience has been regarded as one …

This paper presents a modular-redundant Message Passing Interface (MPI) solution, MR-
MPI, for transparently executing high-performance computing (HPC) applications in a …

Concurrent programs are more difficult to test than sequential programs because of non-
deterministic behavior. An execution of a concurrent program non-deterministically …

The notion of resiliency is concerned with constructing mission-critical distributed
applications that are able to operate through a wide variety of failures, errors, and malicious …

As the number of nodes in high-performance computing environments keeps increasing,
faults are becoming common place. Reactive fault tolerance (FT) often does not scale due to …

This paper revisits replication coupled with checkpointing for fail-stop errors. Replication
enables the application to survive many fail-stop errors, thereby allowing for longer …

Scientists use advanced computing techniques to assist in answering the complex questions
at the forefront of discovery. The High Performance Computing (HPC) scientific applications …

Exascale systems of the future are predicted to have mean time between failures (MTBF) of
less than one hour. At such low MTBFs, employing periodic checkpointing alone will result in …
