The emergence of petascale systems and the promise of future exascale systems have
reinvigorated the community interest in how to manage failures in such systems and ensure …

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

Over the past few years resilience has became a major issue for high-performance
computing (HPC) systems, in particular in the perspective of large petascale systems and …

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 …

We present a new approach to fault tolerance for High Performance Computing system. Our
approach is based on a careful adaptation of the Algorithm-Based Fault Tolerance …

Dense matrix factorizations, such as LU, Cholesky and QR, are widely used for scientific
applications that require solving systems of linear equations, eigenvalues and linear least …

As the scale of computing platforms becomes increasingly extreme, the requirements for
application fault tolerance are increasing as well. Techniques to address this problem by …

The growth in the number of computational resources used by high-performance computing
(HPC) systems leads to an increase in failure rates. Fault-tolerant techniques will become …

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 …

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 …
