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

Attractively illustrated with polemical contemporary engravings, London Crowds demonstrates clearly the value of bringing together both high and low activity into a truly integrated social history of politics, and sheds important new light not just on urban agitation but on the nature of late-Stuart party conflict.

As scholarly interest in popular culture has grown, more and more British and American universities have been introducing courses in popular culture, now seen as an essential aspect of historical investigation.

The late seventeenth century was a period of extraordinary turbulence and political violence in Britain, the like of which has never been seen since. Beginning with the Restoration of the monarchy after the Civil War, this book traces the fate of the monarchy from Charles II's triumphant accession in 1660 to the growing discontent of the 1680s. Harris looks beyond the popular image of Restoration England revelling in its freedom from the austerity of Puritan rule under a merry monarch and reconstructs the human tragedy of Restoration politics where people were brutalised, hounded and exploited by a regime that was desperately insecure after two decade of civil war and republican rule.

To an extraordinary extent everyone in Britain still lives under the shadow of the 'Glorious Revolution' of 1688. It was a massive, brutal and terrifying event, which completely changed the governments of England, Scotland and Ireland and which was only achieved through overwhelming violence. Revolution brilliantly captures the sense that this was a great turning point in Britain's history, but also shows how severe a price was paid to achieve this.

This volume traces the evolution of Whig and Tory, Puritan and Anglican ideas across a tumultuous period of British history, from the mid-seventeenth century through to the Age of Enlightenment.This volume, a tribute to Mark Goldie, traces the evolution of Whig and Tory, Puritan and Anglican ideas across a tumultuous period of British history, from the mid-seventeenth century through to the Age of Enlightenment. Mark Goldie, Fellow of Churchill College and Professor of Intellectual History at Cambridge University, is one of the most distinguished historians of later Stuart Britain of his generation and has written extensively about politics, religion and ideas in Britain from the Restoration through to the Hanoverian succession. Based on original research, the chapters collected here reflect the range of his scholarly interests: in Locke, Tory and Whig political thought,and Puritan, Anglican and Catholic political engagement, as well as the transformative impact of the Glorious Revolution. They examine events as well as ideas and deal not only with England but also with Scotland, France and the Atlantic world. Politics, Religion and Ideas in Seventeenth- and Eighteenth-Century Britain will be of interest to later Stuart political and religious historians, Locke scholars and intellectual historians more generally.
