As the number of nodes in high-performance computing environments keeps increasing, faults are becoming common place causing losses in intermediate results of HPC jobs. Furthermore, storage systems providing job input data have been shown to consistently rank as the primary source of system failures leading to data unavailability and job resubmissions. This dissertation presents a combination of multiple fault tolerance techniques that realize significant advances in fault resilience of HPC jobs. The efforts encompass two broad areas. First, at the job level, novel, scalable mechanisms are built in support of proactive FT and to significantly enhance reactive FT. The contributions of this dissertation in this area are (1) a transparent job pause mechanism, which allows a job to pause when a process fails and prevents it from having to re-enter the job queue; (2) a proactive fault-tolerant approach that combines process-level live migration with health monitoring to complement reactive with proactive FT and to reduce the number of checkpoints when a majority of the faults can be handled proactively; (3) a novel back migration approach to eliminate load imbalance or bottlenecks caused by migrated tasks; and (4) an incremental checkpointing mechanism, which is combined with full checkpoints to explore the potential of reducing the overhead of checkpointing by performing fewer full checkpoints interspersed with multiple smaller incremental checkpoints. Second, for the job input data, transparent techniques are provided to improve the reliability, availability and performance of HPC I/O systems. In this area, the dissertation contributes (1) a mechanism for offline job input data reconstruction to ensure availability of job input data and to improve center-wide performance at no cost to job owners; (2) an approach to automatic recover job input data at run-time during failures by recovering staged data from an original source; and (3) ÃØâ'ƠÅ"just in timeÃØâ'ƠÂ replicatio.

This timely text presents a comprehensive overview of fault tolerance techniques for high-performance computing (HPC). The text opens with a detailed introduction to the concepts of checkpoint protocols and scheduling algorithms, prediction, replication, silent error detection and correction, together with some application-specific techniques such as ABFT. Emphasis is placed on analytical performance models. This is then followed by a review of general-purpose techniques, including several checkpoint and rollback recovery protocols. Relevant execution scenarios are also evaluated and compared through quantitative models. Features: provides a survey of resilience methods and performance models; examines the various sources for errors and faults in large-scale systems; reviews the spectrum of techniques that can be applied to design a fault-tolerant MPI; investigates different approaches to replication; discusses the challenge of energy consumption of fault-tolerance methods in extreme-scale systems.

Pervasive Computing: Next Generation Platforms for Intelligent Data Collection presents current advances and state-of-the-art work on methods, techniques, and algorithms designed to support pervasive collection of data under ubiquitous networks of devices able to intelligently collaborate towards common goals. Using numerous illustrative examples and following both theoretical and practical results the authors discuss: a coherent and realistic image of today’s architectures, techniques, protocols, components, orchestration, choreography, and developments related to pervasive computing components for intelligently collecting data, resource, and data management issues; the importance of data security and privacy in the era of big data; the benefits of pervasive computing and the development process for scientific and commercial applications and platforms to support them in this field. Pervasive computing has developed technology that allows sensing, computing, and wireless communication to be embedded in everyday objects, from cell phones to running shoes, enabling a range of context-aware applications. Pervasive computing is supported by technology able to acquire and make use of the ubiquitous data sensed or produced by many sensors blended into our environment, designed to make available a wide range of new context-aware applications and systems. While such applications and systems are useful, the time has come to develop the next generation of pervasive computing systems. Future systems will be data oriented and need to support quality data, in terms of accuracy, latency and availability.
