GPUs (Graphics Processing Units) have gained wide adoption as accelerators for general purpose computing. They are widely used in error-sensitive applications, i.e. General Purpose GPU (GPGPU) applications However, the reliability implications of using GPUs are unclear. This paper presents a fault injection study to investigate the end-to-end reliability characteristics of GPGPU applications. T...

Failures in production are a de facto rule for distributed software systems. In particular, modern distributed systems are composed of heterogeneous building blocks contributed by third parties and guaranteeing the end-to-end resilience is becoming a major challenge. Even though each of these software components can embed fault tolerance or dependability protocols, it remains difficult to asses...

 Distributed networked applications that are being deployed in enterprise settings, increasingly rely on a large number of heterogeneous hardware and software components for providing end-to-end services. In such settings, the issue of problem diagnosis becomes vitally important, in order to minimize system outages and improve system availability. This mo...

Enterprise-system upgrades are unreliable and often produce downtime or data-loss. Errors in the upgrade procedure, such as broken dependencies, constitute the leading cause of upgrade failures. We propose a novel upgrade-centric fault model, based on data from three independent sources, which focuses on the impact of procedural errors rather than software defects. We show that current approach...

For many years it has been accepted that fibre dimensions are the most important factor in the development of asbestos related disease with long fibres being more dangerous than short for all types of asbestos. This information has been derived from in vitro experiments and injection or implantation experiments since the kilogramme quantities of specially prepared dusts that are necessary for l...

In the research reported in this paper, transient faults were injected in the nodes and in the communication subsystem (by using software fault injection) of a commercial parallel machine running several real applications. The results showed that a significant percentage of faults caused the system to produce wrong results while the application seemed to terminate normally, thus demonstrating t...

Objective: The present study was hypothesized to investigate the beneficial effects of fresh, aged, and cooked garlic extracts on blood glucose and memory of diabetic rats induced by streptozocine (STZ). Material and Methods: Diabetes was induced by an intraperitoneal injection of STZ (60 mg/kg body weight). An oral dose of 1000 mg/kg of each garlic extract was given daily for 4 weeks after dia...

Doppler ultrasound examination revealed signs of tendinosis with significant neovascularity, formed by immature tortuous and dilated vessels into intratendinous mass (Figure 1A). Furthermore, color Doppler scans showed areas of intratendinousedema in the proximal patellar-tendon interface (Figure 1A). After discussing the various treatment options, the patient opted to try etamsylate injection ...
