This is a project to develop and extend support for multithreaded computation on superscalar processors. The intention is to provide high processor utilization despite increasing memory latency. In simultaneous multithreading, multiple independent threads will issue instructions to a superscalar processor's functional units in a single cycle. The objective of this project is to fully define the low-level architecture for simultaneous multithreading, including scheduling, register architecture, pipeline design, and speculative execution. The project is developing compiler and operating systems support for multithreaded execution on the new processor architecture. A primary goal is to maximize multiple thread performance without increasing single thread latency. Most measurements are from detailed simulations, using simulators and compilers provided by industrial partners.

这是一个在超标量处理器上开发和扩展多线程计算支持的项目。其目的是在增加内存延迟的情况下提供高处理器利用率。在并发多线程中，多个独立的线程将在一个周期内向超标量处理器的功能单元发出指令。这个项目的目标是完全定义同步多线程的底层体系结构，包括调度、寄存器体系结构、管道设计和推测执行。该项目正在开发编译器和操作系统对新处理器架构多线程执行的支持。主要目标是在不增加单线程延迟的情况下最大化多线程性能。大多数测量来自详细的模拟，使用工业合作伙伴提供的模拟器和编译器。
