BRIGE: Power-efficient easy-to-program 1000-core desktop supercomputer

前言芯片多处理器形式的并行计算已成为行业标准。预计芯片上的内核数量将继续增加，以在满足热量和功率限制的同时实现持续的性能增长。然而，多核日益增长的功率性能可伸缩性引发了两个主要问题。首先，尚不清楚软件将如何利用日益增长的硬件并行性，其次，功耗和散热限制仍然是主要的设计限制。智能价值本提案侧重于一种特定的现有易编程和易教授的多核体系结构，该体系结构提供了一种不同的并行编程方法，从而针对以上第一个问题。这项工作旨在通过将该体系结构整合到大学水平的并行编程教育中来展示其可编程性。为了解决第二个问题，这项工作旨在研究该架构的功耗，并引入新的功率和热增强。今天？S微处理器行业专注于通用多处理器计算机的单一型号。这项提议解决了一种新的并行计算方法的能效问题，该方法以单任务完成时间为目标。确保新体系结构满足电力和热量限制，将使其成为并行计算的可行替代方法。更广泛的影响这项工作的更广泛的影响是它让学生接触到多核体系结构和并行计算的潜力。这包括为本科生提供节能计算机体系结构和并行编程方面的研究经验，以及将这些主题纳入现有课程和引入新课程。拟议活动的一个主要目标是吸引年轻人学习工程学，并扩大学生在不同科学领域的参与，包括来自目前代表性不足群体的学生。

IntroductionParallel computing in the form of chip multiprocessors has become an industry standard. The number of cores on a chip is expected to continue to increase in an effort to achieve continued performance growth while meeting thermal and power limits. However, the increasing power-performance scalability of multi-cores raises two main concerns. First, it is unclear how software will take advantage of the increasing hardware parallelism, and second, power consumption and thermal constraints are still a major design limitation.Intellectual MeritThis proposal focuses on a particular existing easy-to-program and easy-to-teach multi-core architecture, which provides a different approach to parallel programming, thus targeting the first concern above. The work intends to demonstrate the programmability of this architecture by incorporating it into parallel programming education at the college level. To address the second concern, the work aims to study the power consumption of this architecture and introduce novel power and thermal enhancements. Today?s microprocessor industry focuses on a single model for general-purpose multiprocessor computers. This proposal addresses the energy-efficiency of a new approach to parallel computing, which targets single task completion time. Ensuring that the new architecture meets power and thermal constraints will enable it to serve as a viable alternative approach to parallel computing. Broader ImpactsThe broader impact of this work is its potential to expose students to multicore architectures and parallel computing. This includes providing undergraduate students with research experience in energy-aware computer architecture and parallel programming, as well as incorporating these topics into existing courses and introducing new courses. A main goal of the proposed activities is to attract young people to engineering, as well as broaden participation of students in varied scientific areas, including students from currently underrepresented groups.
