As the computing industry accelerates into the many core era, it is confronted with the need for reliable and accurate simulation, modeling and performance prediction tools for future systems comprised of tens to hundreds of cores per die. Due to different intellectual histories and goals, the integration of mature existing point tools into accurate models of even small 4-8 core systems has proven to be time consuming, error prone, and brittle, with the models themselves taking hours to days for a single simulation run on state-of-the art workstations. Concurrently, these effects make re-use across groups and institutions difficult and have begun to severely inhibit research and teaching progress in many core architectures. The proposed program of work will create an open source many core simulation and modeling infrastructure. This infrastructure, Manifold, will adapt techniques for concurrent simulation to enable existing highly parallel architectures to be harnessed to model future designs. Manifold will enable users to incorporate existing simulation tools when they exist, as well as provide models for key many core components and phenomena, for example interconnection networks. The goal is a software infrastructure that is i) easily accessible to all academic and research communities, ii) runs on commodity clusters, iii) runs on many core laptops for classroom use, and iv) reduces barriers to entry in catalyzing new efforts. Central to Manifolds mission is the development of curricular material for computer architecture modeling and simulation including new courses, course modules, training materials, and significant evangelization.

随着计算行业加速进入多核时代，它面临着对每个芯片包含数十到数百个核的未来系统的可靠和准确的模拟、建模和性能预测工具的需求。由于不同的知识历史和目标，将成熟的现有点工具集成到即使是小型4-8核心系统的准确模型中已被证明是耗时、容易出错和脆弱的，模型本身在最先进的工作站上运行一次模拟需要几个小时到几天的时间。与此同时，这些影响使跨组织和机构的重用变得困难，并已开始严重抑制许多核心体系结构的研究和教学进展。拟议的工作计划将创建一个开源的多核心模拟和建模基础设施。这个基础设施，流形，将采用并发模拟的技术，以使现有的高度并行的架构能够被利用来对未来的设计进行建模。流形将使用户能够整合现有的模拟工具，并为关键的许多核心组件和现象提供模型，例如互联网络。我们的目标是建立一种软件基础设施，即：i)所有学术和研究机构都能轻松访问；ii)在商品集群上运行；iii)在许多核心笔记本电脑上运行以供课堂使用；以及iv)减少促进新努力的进入门槛。流形任务的核心是开发计算机体系结构建模和模拟的课程材料，包括新课程、课程模块、培训材料和重要的布道。
