We propose a novel two-layer error control code, combining error detection capability of rectangular codes and error correction capability of Hamming product codes in an efficient way, in order to increase cache error resilience for many core systems, while maintaining low power, area and latency overhead. Based on the fact of low latency and overhead of rectangular codes and high error control...

Reliability analysis is an important issue in wireless sensor networks (WSNs). This paper aims to study the reliability of a data flow in event-driven wireless sensor networks with multiple sending transmission approach without acknowledgments. Initially, an event-driven wireless sensor network model is described in terms of limited node battery energy and shadowed fading channels. Then, in ord...

This article presents a new approach for system-level reliability management technique for multi-core microprocessors. In the new approach, the electromigration (EM) induced mean time to failure (MTTF) at the system level is modeled as a resource, which is abstracted from a more physics-based EM model. Based on such resource-based EM models, we propose a novel task migration method to explicitl...

This paper is focused on survival analysis of electrical components. The main goal of this paper is to develop a method for on-line estimation of the Mean Time To Failure (MTTF) of electrical components under dynamic stress levels. The proposed method models the variations of the stress levels as a stochastic process. Hence, a stochastic failure rate function can be developed for each electrica...

In airline industries, the aircraft maintenance cost takes up about 13% of the total operating cost. It can be reduced by a good planning. Spare parts inventories exist to serve the maintenance planning. Compared with commonly used reorder point system (ROP) and forecasting methods which only consider historical data, this paper presents two non-linear programming models which predict impending...

An accurate estimate of host reliability is important for correct analysis of many fault-tolerance and replication mechanisms. In a previous study, we estimated host system reliability by querying a large number of hosts to find how long they had been functioning, estimating the mean timeto-failure (MTTF) and availability from those measures, and in turn deriving an estimate of the mean time-to...

Component failure in large-scale IT installations is becoming an ever larger problem as the number of components in a single cluster approaches a million. In this paper, we present and analyze field-gathered disk replacement data from a number of large production systems, including high-performance computing sites and internet services sites. About 100,000 disks are covered by this data, some f...

This paper describes theoretical reliability analysis of a system containing n optical ports in which each port contains m redundant vertical-cavity surface-emitting lasers. We study the wearout failure statistics, modelled with lognormal distribution, for three different chip-level integration approaches: (A) laser on its own chip, resulting m·n chips, (B) lasers associated one channel are sin...
