Architectural and technological trends of systems used for scientific computing call for a
significant reduction of scientific data sets that are composed mainly of floating-point data …

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 …

Modern society is increasingly moving toward complex and distributed computing systems.
The increase in scale and complexity of these systems challenges O&M teams that perform …

We present here a report produced by a workshop on 'Addressing failures in exascale
computing'held in Park City, Utah, 4–11 August 2012. The charter of this workshop was to …

CORAL, the Collaboration of Oak Ridge, Argonne and Livermore, is fielding two similar IBM
systems, Summit and Sierra, with NVIDIA GPUs that will replace the existing Titan and …

Abstract High Performance Computing architectures are expected to change dramatically in
the next decade as power and cooling constraints limit increases in microprocessor clock …

Large scientific applications deployed on current petascale systems expend a significant
amount of their execution time dumping checkpoint files to remote storage. New fault tolerant …

This chapter provides an introduction to resilience methods. The emphasis is on
checkpointing, the de-facto standard technique for resilience in High Performance …

Emerging byte-addressable nonvolatile memories (NVMs) promise persistent memory,
which allows processors to directly access persistent data in main memory. Yet, persistent …

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 …
