This proposal supports the acquisition of an Azul Vega 3 compute appliancefor research on developing an open-source general-purpose transactionalinfrastructure for high-level managed languages. This appliance is equippedwith hundreds of processor cores, substantial memory, and bandwidthavailability. The cores compute in a flat SMP configuration, simplifyingprogrammability and management. The appliance has a number of novelfeatures including hardware support for concurrent garbage collection, andoptimistic lock elision that provide critical building blocks for efficienttransactional memory (TM) support. The project's research agenda is toexplore new approaches to scalable parallel program construction thatexploits underlying hardware primitives that mask or mitigate criticalbottlenecks that have thus far hampered effective scalable softwaretransactional memory systems.The project will use the novel features of the Azul appliance to (i) explorenew language abstractions with special focus on scalability of transactionalapplications; (ii) understand how primitive support for garbage collectionand transactions influence algorithm and application development built usingthese abstractions; (iii) examine the impact of these mechanisms oncompiler and runtime design; and (iv) develop a large number of benchmarksand workloads to better understand TM performance characteristics.This project is part of a larger NSF-funded effort to catalyze TM research,which in turn is a key technique to improving software development forgeneral-purpose parallel computers. Widespread adoption of new scalableconcurrency abstractions such as transactional memory is an essentialcomponent in the technology roadmap of major industry players, and the focusof much attention in academia.

该提案支持收购Azul Vega 3计算设备，用于开发用于高级托管语言的开源通用通用transactionalInfrastructure。 该设备配备了数百个处理器内核，大量内存和带宽的磁性。 核心以平坦的SMP配置计算，简化了程序符合性和管理。 该设备有许多新颖的图案，包括对并发垃圾收集的硬件支持，及以上的锁定责任，可为有效的交流记忆（TM）支持提供关键的构建块。 该项目的研究议程是为可扩展的平行程序构建的新方法塑造了硬件原始构件的可扩展平行程序构建thatexploits，掩盖或减轻了远距离的bitrybottlenecks，这些方法已妨碍了有效的可扩展软质处理记忆系统。 （ii）了解对垃圾收集和交易的原始支持如何影响算法和使用这些抽象构建的应用程序开发； （iii）检查这些机制的影响和运行时设计； （iv）开发大量的基准和工作负载，以更好地了解TM性能特征。该项目是NSF资助的较大努力来催化TM研究的一部分，这反过来又是改善软件开发Mondeneral-Purpose并行计算机的关键技术。 在主要行业参与者的技术路线图中，广泛采用新的ScalableConconconrency抽象（例如交易记忆），是学术界的重点。
