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 …

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

Abstract The Young/Daly formula provides an approximation of the optimal checkpointing
period for a parallel application executing on a supercomputing platform. It was originally …

Advanced computing systems suffer from high static power due to the rapidly rising leakage
currents in deep sub-micron MOS technologies. Fast access non-volatile memories (NVM) …

As machines increase in scale, many researchers have predicted that failure rates will
correspondingly increase. Soft errors do not inhibit execution, but may silently generate …

Supercomputers have seen an exponential increase in their size in the last two decades.
Such a high growth rate is expected to take us to exascale in the timeframe 2018-2022. But …

Checkpoint/Restart (C/R) is a widely used fault tolerance mechanism in converged systems
of cloud, edge, and HPC. However, users often rely on their experience to determine which …

The likelihood of failures rises in cloud computing systems as a result of their unstable
nature. Additionally, the size of a cloud computing system varies with time and thus failures …

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 …

Abstract Shape-from-Shading (SfS) is a fundamental problem in Computer Vision. At its
basis lies the image irradiance equation. Recently, the authors proposed to base the image …
