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 …

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

As supercomputers are entering an era of massive parallelism where the frequency of faults
is increasing, the MPI Standard remains distressingly vague on the consequence of failures …

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 …

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 …

In this paper, we present a unified model for several well‐known checkpoint/restart
protocols. The proposed model is generic enough to encompass both extremes of the …

The resilience approach generally used in high-performance computing (HPC) relies on
coordinated checkpoint/restart, a global rollback of all the processes that are running the …

Apparatuses, systems and methods are disclosed for tolerating fault in a communications
grid. Specifically, various techniques and systems are provided for detecting a fault or failure …

We consider coordinating accesses to shared data structures in multiprocessor real-time
systems scheduled under preemptive global EDF. To our knowledge, prior work on global …

High performance computing will probably reach exascale in this decade. At this scale,
mean time between failures is expected to be a few hours. Existing fault tolerant protocols for …
