Book excerpt: The advent of multi-core architectures and cloud-computing has brought parallel programming into the mainstream of software development. Unfortunately, writing scalable parallel programs using traditional lock-based synchronization primitives is well known to be a hard, time consuming and error-prone task, mastered by only a minority of specialized programmers. Building on the familiar abstraction of atomic transactions, Transactional Memory (TM) promises to free programmers from the complexity of conventional synchronization schemes, simplifying the development and verification of concurrent programs, enhancing code reliability, and boosting productivity. Over the last decade TM has been subject to intense research on a broad range of aspects including hardware and operating systems support, language integration, as well as algorithms and theoretical foundations. On the industrial side, the major players of the software and hardware markets have been up-front in the research and development of prototypal products providing support for TM systems. This has recently led to the introduction of hardware TM implementations on mainstream commercial microprocessors and to the integration of TM support for the world’s leading open source compiler. In such a vast inter-disciplinary domain, the Euro-TM COST Action (IC1001) has served as a catalyzer and a bridge for the various research communities looking at disparate, yet subtly interconnected, aspects of TM. This book emerged from the idea having Euro-TM experts compile recent results in the TM area in a single and consistent volume. Contributions have been carefully selected and revised to provide a broad coverage of several fundamental issues associated with the design and implementation of TM systems, including their theoretical underpinnings and algorithmic foundations, programming language integration and verification tools, hardware supports, distributed TM systems, self-tuning mechanisms, as well as lessons learnt from building complex TM-based applications.

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. Table of Contents: Introduction / Basic Transactions / Building on Basic Transactions / Software Transactional Memory / Hardware-Supported Transactional Memory / Conclusions

Available in PDF, EPUB and Kindle. Book excerpt: Transactional memory (TM) is an appealing paradigm for concurrent programming on shared memory architectures. With a TM, threads of an application communicate, and synchronize their actions, via in-memory transactions. Each transaction can perform any number of operations on shared data, and then either commit or abort. When the transaction commits, the effects of all its operations become immediately visible to other transactions; when it aborts, however, those effects are entirely discarded. Transactions are atomic: programmers get the illusion that every transaction executes all its operations instantaneously, at some single and unique point in time. Yet, a TM runs transactions concurrently to leverage the parallelism offered by modern processors. The aim of this book is to provide theoretical foundations for transactional memory. This includes defining a model of a TM, as well as answering precisely when a TM implementation is correct, what kind of properties it can ensure, what are the power and limitations of a TM, and what inherent trade-offs are involved in designing a TM algorithm. While the focus of this book is on the fundamental principles, its goal is to capture the common intuition behind the semantics of TMs and the properties of existing TM implementations.

Download or read book A Study of Hybrid Transactional Memory written by Fu'ad W. F. Al Tabba' and published by . This book was released on 2011 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rise of multicore processors is driving programmers towards parallel programming. Traditional lock-based parallel programming, however, breaks abstraction, hinders composition, and is further complicated by issues such as deadlock, priority inversion, and lack of scalability. Transactional memory, a promising programming model inspired by database transactions, is gaining popularity as a way to overcome the drawbacks of lock-based programming and make it easier to write parallel programs. Different methods have been proposed for supporting transactional memory. Hardware proposals, which modify a processor's existing hardware to support transactions, are either too complex, or cannot handle all types of workload. Software proposals, which do not require any hardware support beyond what is already present for parallel programming, are too slow. This thesis argues that transactional memory should be supported by a hybrid combination of hardware and software. By combining the two, transactional memory can offer the best of both hardware and software. To support this argument, this thesis presents my work on transactional memory, which spans the areas of hardware, software, and hybrid support. This thesis presents NZSTM, the first nonblocking, object-based, software transactional memory that does not require indirection to access data in the common case. It also presents NZTM, a hybrid transactional memory that uses NZSTM as its software component. The evaluation presented shows that nonblocking support introduces little overhead compared with blocking algorithms, and that NZTM is competitive with pure hardware transactional memory. Furthermore, this thesis investigates how to improve the performance of hardware transactional memory by using data speculation in transactions, and how to reduce transactional conflicts by decoupling them from cache coherence conflicts. Most hardware proposals do not distinguish between transactional conflicts and coherence conflicts, leading to false transactional conflicts. This thesis explains how to mitigate the effects of coherence conflicts by using value prediction in transactions. It also shows that coherence decoupling and value prediction in transactions complement each other, because they both speculate on data in ways that are infeasible in the absence of hardware transactional memory support.

Download or read book Software Transactional Memory for Distributed and Event based Systems written by and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the availability of end-user multi-core systems, new concurrency control systems have been developed. One of them, software transactional memory (STM) uses optimistic execution of code within transactions. In this thesis, we propose the application of the STM technology with event stream processing(ESP). In ESP applications, events flow through a network of components that perform various types of operations, e.g., filtering, aggregation, transformation. Our approach, simplifie the parallelization of stateful components by reducing the complex and error-prone parallel programing to a minimum. Additionally, we present a directed distributed STM, which can extend the transactions from one component to the attached downstream components. To underline the advantages of our approaches and developments, we depict several use cases as well as a basic guideline for them. Furthermore, we present our work in building a lightweight STM support for the unmanaged programming language C based on LLVM. The resulting framework can produce highly efficient STM-based applications without letting the programmer deal with too much parallelization aspects. The system is very flexibl and can be used with a large group of C-based STMs. In the third aspect of this thesis we analyze the STM approach for solving concurrency problems and propose a "Transactional Object" design pattern. With this proposal we want to support application designers and STM programmers with a blueprint to simplify their work.
