A Unified Open-Source Transactional-Memory Infrastructure

随着通用计算进入普遍并行的时代，可编程性成为限制可用计算资源有效使用的关键障碍。事务内存有望简化应用程序编程人员的并行编程。然而，由于缺乏可重复使用的开源基础设施，事务性内存的研究正受到严重阻碍。该项目将开发克服这种情况所需的关键部件：由高度分解的部件构建的事务存储器库将提供适合于研究软件TM实现中的权衡的可重复使用和可替换的部件。标准化接口将允许符合接口的库在各种环境中使用。TM感知的运行时分析工具，特别是分析器和调试器，将为TM实现者和应用程序程序员提供必要的工具支持，以了解和改进使用事务的软件的性能。各种高级语言中的有趣基准将推动我们对TM性能特征的理解。

As general-purpose computing moves into the age of pervasive parallelism, programmability becomes the key hurdle limiting the effective use of available computing resources. Transactional memory promises to simplify parallel programming for application programmers. However, research in Transactional Memory is being seriously hampered by the lack of a reusable open source infrastructure. The project will develop the key pieces necessary to overcome this situation: A transactional memory library built out of highly decomposed pieces will provide reusable and replaceable parts suitable for investigating tradeoffs in software TM implementations. Standardized interfaces will allow libraries conforming to the interfaces to be used in a variety of environments. TM-aware run-time analysis tools, particularly profilers and debuggers, will provide the necessary tool support for TM implementors and application programmers to understand and improve the performance of software using transactions. Interesting benchmarks, in a variety of high-level languages, will move forward our understanding of TM performance characteristics.
