Available in PDF, EPUB and Kindle. Book excerpt: The advent of multicore processors has renewed interest in the idea of incorporating transactions into the programming model used to write parallel programs. This approach, known as transactional memory, offers an alternative, and hopefully better, way to coordinate concurrent threads. The ACI (atomicity, consistency, isolation) properties of transactions provide a foundation to ensure that concurrent reads and writes of shared data do not produce inconsistent or incorrect results. At a higher level, a computation wrapped in a transaction executes atomically - either it completes successfully and commits its result in its entirety or it aborts. In addition, isolation ensures the transaction produces the same result as if no other transactions were executing concurrently. Although transactions are not a parallel programming panacea, they shift much of the burden of synchronizing and coordinating parallel computations from a programmer to a compiler, to a language runtime system, or to hardware. The challenge for the system implementers is to build an efficient transactional memory infrastructure. This book presents an overview of the state of the art in the design and implementation of transactional memory systems, as of early spring 2010.

Download or read book Shared-Memory Synchronization written by Michael Lee Scott and published by Springer Nature. This book was released on 2024 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zusammenfassung: This book offers a comprehensive survey of shared-memory synchronization, with an emphasis on "systems-level" issues. It includes sufficient coverage of architectural details to understand correctness and performance on modern multicore machines, and sufficient coverage of higher-level issues to understand how synchronization is embedded in modern programming languages. The primary intended audience for this book is "systems programmers"--the authors of operating systems, library packages, language run-time systems, concurrent data structures, and server and utility programs. Much of the discussion should also be of interest to application programmers who want to make good use of the synchronization mechanisms available to them, and to computer architects who want to understand the ramifications of their design decisions on systems-level code

Available in PDF, EPUB and Kindle. Book excerpt: "Multithreaded programming requires synchronization, to coordinate access to shared resources. As more and more processor cores become available on a single machine, synchronization tends to be the performance bottleneck of many multithreaded programs. This thesis focuses on two important synchronization scenarios: lock-based critical sections and transactional atomic blocks. Since speculation is a well-known means of increasing parallelism among concurrent executions that are usually but not always independent, this thesis first explores the manual addition of speculation to lock-based critical sections (in concurrent data structures). With simple language extensions accompanied by compiler assistance, a technique which we refer to as CSpec, the programmer can exploit high-level program knowledge to move speculative work out of lock-based critical sections, thereby improving scalability while still maintaining correctness. Speculation is also a major approach to improved parallelism in transactional memory systems. Frequent failures of speculative execution, however, may render the technique unprofitable. In recently emerged best-effort hardware transactional memory, speculation fails mainly due to two reasons: hardware overflow and data conflicts. In this thesis we develop a programming technique and compiler support, ParT, to reduce the duration and memory footprint of hardware transactions, leading to lower abort rates while preserving deadlock-free composability. To reduce the incidence of conflict, we propose an automatic, high-level mechanism, Staggered Transactions, that uses advisory locks to serialize (just) the portions of the transactions in which conflicting accesses occur. In all proposed techniques, compiler assistance is essential to maintaining ease of programming. We thus conclude that compiler assistance can significantly improve speculation in multithreaded systems"--Pages vii-viii.

Available in PDF, EPUB and Kindle. Book excerpt: With growing memory sizes and memory prices dropping by a factor of 10 every 5 years, data having a "primary home" in memory is now a reality. Main-memory databases eschew many of the traditional architectural pillars of relational database systems that optimized for disk-resident data. The result of these memory-optimized designs are systems that feature several innovative approaches to fundamental issues (e.g., concurrency control, query processing) that achieve orders of magnitude performance improvements over traditional designs. This monograph provides an overview of recent developments in main-memory database systems. It covers five main issues and architectural choices that need to be made when building a high performance main-memory optimized database: data organization and storage, indexing, concurrency control, durability and recovery techniques, and query processing and compilation. The monograph focuses on four commercial and research systems: H-Store/VoltDB, Hekaton, HyPer, and SAPHANA. These systems are diverse in their design choices and form a representative sample of the state of the art in main-memory database systems. It also covers other commercial and academic systems, along with current and future research trends.

Available in PDF, EPUB and Kindle. Book excerpt: Synchronization hardware is a fundamental requirement for concurrent software. Ultimately, software depends upon strong guarantees for atomicity, which can only be provided by hardware. Fortunately, hardware can provide a simple but powerful programming interface to higher-level software using only a few synchronization primitives. These few primitives can support a surprisingly broad range of capabilities in software. Yet, even with hardware support to ensure functional correctness, there is an unavoidable performance overhead to pay for synchronization. In recent years, hardware designed to replace precise locking with speculative lock avoidance (e.g., lock-free programming) has begun to emerge. This chapter provides an in-depth look at the lowest level hardware/software interface for synchronization, along with explanations of how the underlying hardware ensures atomicity, and considerations related to weakly consistent memory models. This is complemented with a discussion of various lock avoidance techniques.
