Reliability is set to become a major concern on emergent large-scale architectures. While there are many parallel languages, and indeed many parallel functional languages, very few address reliability. The notable exception is the widely emulated Erlang distributed actor model that provides explicit supervision and recovery of actors with isolated state. We investigate scalable transparent faul...

The objective of ESPRIT-project 6731 FTMPS [1] is to develop techniques and system software to integrate Fault Tolerance in Massively Parallel Systems [2] . This covers the whole range from error detection, over fault-diagnosis and fault isolation to system and application recovery. Important is the research for applicability in massively parallel systems as well as the development of system so...

Scalable fault diagnosis is necessary for constructing fault tolerance mechanisms in large massively parallel multiprocessor systems. The diagnosis algorithm must operate efficiently even if the system consists of several thousand processors. In this paper we introduce an event-driven, distributed system-level diagnosis algorithm. It uses a small number of messages and is based on a general dia...

The paper presents a novel modelling technique for system-level fault diagnosis in massive parallel multiprocessors, based on a re-formulation of the problem of syndrome decoding to a constraint satisfaction problem (CSP). The CSP based approach is able to handle detailed and inhomogeneous functional fault models to a similar depth as the Russel-Kime model [18]. Multiple-valued logic is used to...

Barrier synchronization is a crucial operation for parallel systems. Many schemes have been proposed in the literature to achieve fast barrier synchronization through software, hardware, or a combination of these mechanisms. However, few of these schemes emphasize fault-tolerant barrier operations. In this paper, we describe inexpensive support that can be added to network switches for achievin...

Fault tolerance is still an “hot” topic in the context of Grid computing. There exist several solutions and techniques to face this issue, some of them inherited from the fault tolerance research, some other introduced in the context of Grid computing. Anyway, poor work has been done in providing such fault tolerance strategies in a lightweight, scalable and analyzable way. In this technical re...

S U M M A R Y We perform a systematic analysis of crustal anisotropy along and around the Karadere–Düzce branch of the North Anatolian fault (NAF), which ruptured during the 1999 Mw 7.4 İzmit and Mw 7.1 Düzce earthquakes. A method consisting of an iterative grid search for the best shear wave splitting parameters in sliding time windows is applied to ∼22 000 measurements recorded in the 6-month...

The increasing complexity of processors allied to the continuous technology shrink is making multicore-based systems more susceptible to soft errors. The high cost and time inherent to hardware-based fault injection approaches make the more efficient simulation-based fault injection frameworks crucial to test reliability. This paper proposes a fast, flexible fault injector framework which suppo...

AI-based search techniques have been adapted as viable, topology-independent fault-tolerant routing strategies on multiprocessor networks [P.K.K. Loh, Artificial intelligence search techniques as fault-tolerant routing strategies, Parallel Computing 22 (8) (1996) 1127–1147]. These fault-tolerant routing strategies are viable with the exception that the routes obtained were non-minimal. This mea...
