Requirements for reliability, low power consumption, and performance place complex and
conflicting demands on the design of high-performance computing (HPC) systems. Fault …

An exascale machine is expected to be delivered in the time frame 2018-2020. Such a
machine will be able to tackle some of the hardest computational problems and to extend …

With the increase in scale of HPC systems, the frequency of system wide failures is expected
to increase. The performance of Coordinated Checkpoint/Restart (C/R), the traditional fault …

The high failure rate expected for future supercomputers requires the design of new fault
tolerant solutions. Most checkpointing protocols are designed to work with any message …

Abstract Checkpoint/restart (C/R) is a classical approach to introduce fault tolerance in large
HPC applications. Although it is relatively easy as compared to other fault tolerance …

Failures are increasingly threatening the efficiency of HPC systems, and current projections
of Exascale platforms indicate that rollback recovery, the most convenient method for …

Efficient use of high-performance computing (HPC) installations critically relies on effective
methods for fault tolerance. The most commonly used method is checkpoint/restart, where …

In order to efficiently use the future generations of supercomputers, fault tolerance and
power consumption are two of the prime challenges anticipated by the High Performance …

Abstract In recent years, High Performance Computing (HPC) systems have been shifting
from expensive massively parallel architectures to clusters of commodity PCs to take …

This paper revisits the failure 1 temporal independence hypothesis which is omnipresent in
the analysis of resilience methods for HPC. We explain why a previous approach is …
