Resilience is a major roadblock for HPC executions on future exascale systems. These
systems will typically gather millions of CPU cores running up to a billion threads …

As high-end computing machines continue to grow in size, issues such as fault tolerance
and reliability limit application scalability. Current techniques to ensure progress across …

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 …

Reliability is a serious concern for future extreme-scale high-performance computing (HPC)
systems. While the HPC community has developed various resilience solutions, the solution …

Fault tolerance for the upcoming exascale generation has long been an area of active
research. One of the components of a fault tolerance strategy is checkpointing. Petascale …

Efficient utilization of today's high-performance computing (HPC) systems with complex
software and hardware components requires that the HPC applications are designed to …

With the aim of imaging subsurface discontinuities, seismic data recorded at the surface of
the Earth must be numerically re-positioned at locations in the subsurface where reflections …

The construction of distributed algorithms for matrix computations built on top of distributed
data aggregation algorithms with randomized communication schedules is investigated. For …

In this document, we develop a structured approach to the management of HPC resilience
based on the concept of resilience-based design patterns. A design pattern is a general …

Handling faults is a growing concern in HPC. In future exascale systems, it is projected that
silent undetected errors will occur several times a day, increasing the occurrence of …
