Book Description
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. Transactions are atomic: programmers get the illusion that every transaction executes all its operations instantaneously, at some single and unique point in time. The aim of this book is to provide theoretical foundations for transactional memory.

Book Description
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.

Book Description
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

Book Description
Many modern computer systems, including homogeneous and heterogeneous architectures, 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 high-level concepts as well as specific, concrete examples from real-world systems. This second edition reflects a decade of advancements since the first edition and includes, among other more modest changes, two new chapters: one on consistency and coherence for non-CPU accelerators (with a focus on GPUs) and one that points to formal work and tools on consistency and coherence.

Book Description
We are pleased to welcome you to the eleventh edition of the Middleware c- ference. The program this year is a sign of the robustness, activity, and cont- ued growth of the Middleware community. As computing technology around us has evolved rapidly over the past decade, our notions of middleware have also adapted so that we stay focused on the most challenging and relevant problems for the present and future. As a result, this year’s program features papers that belong to both tra- tional areas as well as new directions. Cloud computing, social middleware, and transactional memory are some of the vanguard areas that you will ?nd in this year’s selection of papers. In addition, topics that have always been central to the community are also prominent this year, including publish-subscribe, mul- cast,reliability, legacy,location-awareness,trust, and security.The community’s wise evolutionre?ects the dynamic role that middleware continues to play in the development of current software systems. The program underscores the competitive selection process applied by us and the technical programcommittee: out of 116 papers submitted this year,we accepted 18 for regular publication. In addition Middleware 2010 also includes a new category of “Big Ideas Papers,” which are bold white papers with the potentialtodrivelonger-terminnovationinthe?eld.Weselectedone“bigideas” paper this year. Our industrial track once againbrings forth papers that explore middleware foundations in the context of industrial practice. Finally, multiple workshops and a doctoral symposium round o? Middleware this year, making it an attractive conference for students, faculty, researchers, and practitioners.

Book Description
Although multicore is now a mainstream architecture, there are few textbooks that cover parallel multicore architectures. Filling this gap, Fundamentals of Parallel Multicore Architecture provides all the material for a graduate or senior undergraduate course that focuses on the architecture of multicore processors.

Book Description
These post-proceedings contain the revised versions of the accepted papers of the international workshop \Transactions and Database Dynamics", which was the eighth workshop in a series focusing on foundations of models and languages for data and objects (FoMLaDO). Seven long papers and three short papers were accepted for inclusion in the proceedings. The papers address various issues of transactions and database dynamics: { criteria and protocols for global snapshot isolation in federated transaction management, { uni ed theory of concurrency control and replication control, { speci cation of evolving information systems, { inheritance mechanisms for deductive object databases with updates, { speci cation of active rules for maintaining database consistency, { integrity checking in subtransactions, { open nested transactions for multi-tier architectures, { declarative speci cation of transactions with static and dynamic integrity constraints, { logic-based speci cation of update queries as open nested transactions, and { execution guarantees and transactional processes in electronic commerce payments. In addition to the regular papers, there are papers resulting from two working groups. The rst working group paper discusses the basis for transactional c- putation. In particular, it addresses the speci cation of transactional software. The second working group paper focuses on transactions in electronic commerce applications. Among others, Internet transactions, payment protocols, and c- currency control and persistence mechanisms are discussed. Moreover, there is an invited paper by Jari Veijalainen which discusses tr- sactional aspects in mobile electronic commerce.
