CAREER: A Simultaneous Multithreading System Architecture

该项目的研究部分推进了同时多线程的研究，这是一种处理器架构技术，旨在提高在每个时钟周期发出多条指令的处理器中执行资源的利用率。 研究的目标有三个方面：（1）重新评估内存系统架构的同时多线程的工作负载;（2）调查处理器的问题，如同步方法和策略，以处理大型寄存器文件;（3）解决的影响，同时多线程的软件系统。 这项工作需要改造现有的多线程处理器的模拟器，并使用新的模拟器在评估替代品。 教育部分集中在计算机体系结构的部门课程的改造。 目前正在引进新的计算机体系结构研究生课程，同时多线程正在被纳入本科生的核心体系结构课程。 所有课程的工作正在加强与实践级模拟实验。

The research portion of this project advances the study of simultaneous multithreading, a processor architecture technique aimed at increasing the utilization of the execution resources in processors that issue multiple instructions in each clock cycle. The research objectives are threefold: (1) to re-evaluate memory system architecture in light of a simultaneous multithreaded workload; (2) to investigate processor issues such as synchronization methods and strategies to deal with large register files; (3) to address the implications of simultaneous multithreading on the software system. The work entails revamping of an existing simulator for multithreaded processors, and use of the new simulator in evaluating alternatives. The educational portion concentrates on a revamping of the department curriculum in computer architecture. New graduate courses on computer architecture are being introduced, and simultaneous multithreading is being integrated into the core architecture courses for undergraduates. All course work is being enhanced with hands-on experimentation with instruction-level simulation.
