Presidential Young Investigator Award: Architectural Issues in Parallel and Distributed Computing

Ramachandran Beehive是一个研究可扩展共享内存多处理器设计中的软件和硬件问题的项目。 该体系结构的设计是为了在基于缓存的多处理器环境中支持一种形式的弱一致性内存模型。 该架构的新颖方面是读取器启动的高速缓存一致性、通过缓冲写入的延迟容忍、消除错误共享以及通过高速缓存对同步的有效支持。 该体系结构特征被设计为与互连网络兼容。 研究问题包括：在探索的弱内存模型和架构功能，新的模拟技术，这种复杂的并行系统的评估，并探索这种可扩展的架构的光互连的并行时间和运行时的问题。

Ramachandran Beehive is a project that investigates the software and hardware issues in the design of scalable shared memory multiprocessors. The architecture is designed to support a form of weakly consistent memory model in a cache-based multiprocessor environment. The novel aspects of the architecture are reader- initiated cache coherence, latency tolerance through buffered writes, elimination of false-sharing, and efficient support for synchronization via the caches. The architectural features are designed to be compatible with an interconnection network. Research issues include: Compile-time and runtime issues in the exploration of the weak memory model and the architectural features, novel simulation techniques for the evaluation of such complex parallel systems, and exploration of optical interconnects for such scalable architectures.
