Available in PDF, EPUB and Kindle. Book excerpt: Distributed shared memory (DSM) implemented on a cluster of workstations is an increasingly attractive platform for executing parallel scientific applications. Checkpointing and rollback techniques can be used in such a system to allow the computation to progress in spite of the temporary failure of one or more processing nodes. The complexity and overhead inherent in traditional message-passing checkpointing techniques can be reduced by taking advantages of specific properties of DSM. In this paper we show that, if designed correctly, a DSM system only needs to consider a subset of message-passing dependencies for correct rollback. A passive server model of DSM computation is described that allows a loosening of dependency restrictions by considering the events involved in interactions between nodes as atomic. An ownership timestamp scheme is used to eliminate many of the dependencies related to keeping directories consistent. The schemes can be implemented in DSM hardware by simply redesigning the directory at the network interface. Finally, we show that by relaxing the memory consistency model and using lazy release consistency, it is possible to further relax dependency restrictions. (AN).

Available in PDF, EPUB and Kindle. Book excerpt: Relaxed memory consistency models tolerate increased memory access latency in both hardware and software distributed shared memory systems. In recoverable systems, relaxing consistency has the added benefit of reducing the number of checkpoints needed to avoid rollback propagation. In this paper, we introduce new checkpointing algorithms that take advantage of relaxed consistency to reduce the performance overhead of checkpointing. We also introduce a scheme based on lazy relaxed consistency, that reduces both checkpointing overhead and the overhead of avoiding error propagation in systems with error latency. We use multiprocessor address traces to evaluate the relaxed consistency approach to checkpointing with distributed shared memory.

Book excerpt: The proposed scheme supports local process recovery without forcing rollback of operational processes during recovery. Our method is particularly useful in environments where taking process checkpoints is expensive (e.g., in some UNIX [trademark] environments)."

Available in PDF, EPUB and Kindle. Book excerpt: The papers present in this text survey both distributed shared memory (DSM) efforts and commercial DSM systems. The book discusses relevant issues that make the concept of DSM one of the most attractive approaches for building large-scale, high-performance multiprocessor systems. The authors provide a general introduction to the DSM field as well as a broad survey of the basic DSM concepts, mechanisms, design issues, and systems. The book concentrates on basic DSM algorithms, their enhancements, and their performance evaluation. In addition, it details implementations that employ DSM solutions at the software and the hardware level. This guide is a research and development reference that provides state-of-the art information that will be useful to architects, designers, and programmers of DSM systems.

Available in PDF, EPUB and Kindle. Book excerpt: Providing a shared memory abstraction in distributed systems is a powerful tool that can simplify the design and implementation of software systems for networked platforms. This enables the system designers to work with abstract readable and writable objects without the need to deal with the complexity and dynamism of the underlying platform. The key property of shared memory implementations is the consistency guarantee that it provides under concurrent access to the shared objects. The most intuitive memory consistency model is atomicity because of its equivalence with a memory system where accesses occur serially, one at a time. Emulations of shared atomic memory in distributed systems is an active area of research and development. The problem proves to be challenging, and especially so in distributed message passing settings with unreliable components, as is often the case in networked systems. We present several approaches to implementing shared memory services with the help of replication on top of message-passing distributed platforms subject to a variety of perturbations in the computing medium.

Download or read book Checkpointing and Rollback Recovery in Distributed Shared Memory Systems written by and published by . This book was released on 1994 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Checkpointing techniques in parallel systems use dependency tracking and/or message logging to ensure that a system rolls back to a consistent state. Traditional dependency tracking in distributed shared memory systems (DSM) is expensive because of high frequency of communication. In this paper we show that, because of information redundancy, not all message-passing dependences need to be considered to roll back to a consistent state in DSM systems, resulting in reduced dependency tracking overhead and reduced potential for rollback propagation. We develop a model of execution where client processes running an application interact atomically with a set of shared-memory server processes on every access to shared data. We show that under this model, dependences are significantly reduced over the message-passing model. We use results from simulation with multiprocessor address traces to demonstrate the reduction in dependences.

Book excerpt: Abstract: "Atomic transactions have proven to be an important technique for constructing reliable applications. Traditionally, transactions have been extended to distributed environments through the use of function shipping, a technique in which message passing or remote procedure calls are used to invoke computational requests on remote nodes. Recently, the data sharing approach to constructing distributed applications has received attention in the form of distributed file systems and distributed shared virtual memory. Applying the data sharing approach to transactions produces transactional distributed shared memory (TDSM) which yields benefits for a certain class of distributed application
