Technology limitations, emerging applications, and changing usability trends are ushering in a new era in multi-core computer systems. A key problem for both application and microprocessor design is that applications are largely evolving independently from the architectural development of microprocessors. This is a problem for architectural research because developing efficient architectural solutions requires realistic characterization of the next generation applications. From a system design perspective, understanding application behavior is crucial for building an efficient system, since they must be optimized to exploit mechanisms provided in the architecture. This proposal seeks to re-think next generation multi-core systems - both softwareand hardware architectures using state-of-the-art quantitative designtools.The two key ideas explored in this research are the following. First, is a hybrid task-level/data-level parallelism execution model for emerging applications that have abundant but not synchronization-free parallelism. Second, is the development of new highly accurate and efficient quantitative models to evaluate architecture and application design alternatives, at scale and over a wide range of application workloads. The project seeks to provide a suite of quantitative tools to close the development loop of design, evaluation and analysis of software's behavior on hardware, allowing the tuning of both software and hardware. This project takes real-time graphics as a challenge application and derives a full system, called Copernicus, for future real-time graphics that can provide significantly higher imagequalities. The project will also integrate these quantitative models in the curriculum and disseminate to the research community.The innovations proposed in this research have the potential for significantly aiding microprocessor and application development for future systems. The development of a full system specification for ray-tracing can trigger an inflection in the evolution of both programmable processors andspecialized graphics processors.

技术局限性，新兴应用程序和可用性趋势的变化正在吸引多核计算机系统的新时代。应用程序和微处理器设计的一个关键问题是，应用程序在很大程度上与微处理器的建筑发展独立发展。这是建筑研究的问题，因为开发有效的建筑解决方案需要对下一代应用的现实表征。从系统设计的角度来看，了解应用程序行为对于构建有效的系统至关重要，因为必须优化它们以利用体系结构中提供的机制。 该建议旨在重新考虑下一代多核系统 - 使用最先进的定量设计工具使用软件硬件架构。这项研究中探讨的两个关键思想是以下内容。首先，是针对具有丰富但不含同步并行性的新兴应用程序的混合任务级/数据级并行性执行模型。其次，开发了新的高度准确和高效的定量模型，以评估体系结构和应用设计替代方案，并在广泛的应用程序工作上进行。该项目旨在提供一套定量工具，以关闭软件上软件行为的设计，评估和分析的开发循环，从而可以对软件和硬件进行调整。 该项目将实时图形作为挑战应用程序，并为未来的实时图形提供了一个完整的系统，称为哥白尼，可以提供明显更高的图像质量。该项目还将将这些定量模型整合到课程中，并将其传播到研究界。本研究中提出的创新有可能在未来系统中有效地有助于微处理器和应用程序开发。用于射线追踪的完整系统规范的开发可以触发可编程处理器的演变和特定图形处理器的变化。
