Current trends and projections show that faults in computer systems become increasingly
common. Such errors may be detected, and possibly corrected transparently, eg, by Error …

This paper presents a method to protect iterative solvers from Detected and Uncorrected
Errors (DUE) relying on error detection techniques already available in commodity …

Several recent papers have introduced a periodic verification mechanism to detect silent
errors in iterative solvers. Chen [PPoPP'13, pp. 167--176] has shown how to combine such a …

We present a fault model designed to bring out the" worst" in iterative solvers based on
mathematical properties. Our model introduces substantially higher overhead, but smaller …

Soft errors caused by transient bit flips have the potential to significantly impact an
application's behavior. This has motivated the design of an array of techniques to detect …

Iterative methods are commonly used approaches to solve large, sparse linear systems,
which are fundamental operations for many modern scientific simulations. When the large …

Emerging high-performance computing platforms, with large component counts and lower
power margins, are anticipated to be more susceptible to soft errors in both logic circuits and …

As parallel and distributed systems scale, fault tolerance is an increasingly important
problem—particularly on systems with limited I/O capacity and bandwidth. Erasure coded …

The scale of nowadays High Performance Computing (HPC) systems is the key element that
determines the achievement of impressive performance, as well as the reason for their …
