Download or read book A Primer on Memory Consistency and Cache Coherence written by Daniel J. Sorin and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many modern computer systems and most multicore chips (chip multiprocessors) support shared memory in hardware. In a shared memory system, each of the processor cores may read and write to a single shared address space. For a shared memory machine, the memory consistency model defines the architecturally visible behavior of its memory system. Consistency definitions provide rules about loads and stores (or memory reads and writes) and how they act upon memory. As part of supporting a memory consistency model, many machines also provide cache coherence protocols that ensure that multiple cached copies of data are kept up-to-date. The goal of this primer is to provide readers with a basic understanding of consistency and coherence. This understanding includes both the issues that must be solved as well as a variety of solutions. We present both highlevel concepts as well as specific, concrete examples from real-world systems.

This book was released on 1994 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overall, this work demonstrates that update-based protocols can be used not only as a coherence mechanism, but also as a latency reducing and tolerating technique to improve the performance of a set of fine-grain scientific applications. But as with other latency reducing techniques, such as data prefetch, the technique must be used with an understanding of its consequences.

This book was released on 1993 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, two hardware-controlled update-based cache coherence protocols are presented. The paper discusses the two major disadvantages of the update protocols: inefficiency of updates and the mismatch between the granularity of synchronization and the data transfer. The paper presents two enhancements to the update-based protocols, a write combining scheme and a finer grain synchronization, to overcome these disadvantages. The results demonstrate the effectiveness of these enhancements that, when used together, allow the update-based protocols to significantly improve the execution time of a set of scientific applications when compared to three invalidate-based protocols.
Download or read book Synchronization in Timestamp based Cache Coherence Protocols written by Quan Minh Nguyen (S.M.) and published by . This book was released on 2016 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supporting computationally demanding workloads into the future requires that multiprocessor systems support hundreds or thousands of cores. A cache coherence protocol manages the memory cached by these many cores, but the storage overhead required by existing directory-based protocols to track coherence state scales poorly as the number of cores increases. The Tardis cache coherence protocol uses timestamps to avoid these scalability problems. We build a cycle-level multicore simulator that implements a version of the Tardis protocol that uses release consistency. Changing the coherence protocol, which affects what memory values a processor can observe, changes inter-processor communication and synchronization, two processes crucial to the operation of a multicore system. We construct Tardis versions of synchronization primitives and the atomic instructions they use, and compare them to their analogous implementations on a directory-based cache coherent multicore system. Simulations on several benchmarks suggest that the Tardis system performs just as well as the baseline system while preserving the ability to scale systems to hundreds or thousands of cores.

This book was released on 1994 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In cooperative applications such as group CAD and group software development systems, multiple processes communicate with each other by sharing complex data consisting of nested structures and pointers. Although the sharing of complex data structures in the distributed environment is achieved through the technology of distributed shared memory, a single cache coherence protocol cannot efficiently serve various access patterns generated by cooperative applications. By having a framework for allowing cooperative applications to customize coherence protocols according to their behaviors, hence, significant improvement of run-time efficiency is expected. This paper describes a framework of protocol customization for the sharing of volatile and persistent data in cooperative applications. The major obstacle in user-level customization of protocols is that there are too many states and state transitions in an unabstracted protocol to enable average users to describe them. The protocol customization system (PCS) in this paper solves this problem by introducing high-level model for protocol description that abstracted away non-determinism of messages, synchronization among hosts, and local paging actions. Consequently, users can define with brief descriptions cache coherence protocols that are adapted for particular applications. The ability of PCS to describe different kinds of protocols is examined in this paper, and its run-time performance and memory usages are investigated."

This book was released on 2012-12-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

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.
