Computer science and engineering is undergoing a revolution. Many-core systems are rapidly becoming the foundation of computing systems that are well-integrated into every aspect of our lives and society. Their unpredictable performance and performance misbehavior adversely affects productivity, efficiency, and profit in all domains that make use of computers. Unfortunately, existing many-core systems are largely designed based on the assumptions made for single-core systems, i.e. there are no shared resources between cores, even though the memory system, a major performance and power bottleneck, is shared. As a result, many-core systems are severely vulnerable to denial of service, uncontrollable, unscalable, and low-performance. To enable the efficient and productive use of many-core systems, there is an urgent need to design them ensuring high quality-of-service (QoS), performance-robustness, and scalability.This research focuses on developing fundamental breakthroughs that enable scalable, controllable, and high-performance many-core memory systems. It aims to change the design paradigm of many-core processors to treat QoS and scalability in shared resources as first-class design goals, and educate future engineers to design systems with these goals as fundamental design objectives. The central approach is to develop hardware/software cooperative techniques to enable flexible QoS, partitioning, and performance mechanisms in memory systems and interconnects. The project develops fundamental techniques, targeting a very wide range of applications in cloud computing, data centers, client systems, mobile systems, and sensor environments. It is expected that research ideas developed in this project will enable controllable, robust, and therefore usable and efficient many-core systems, making our daily lives better and more productive, and taking a large step in making computing green.

计算机科学与工程正在经历一场革命。多核系统正迅速成为计算系统的基础，这些系统已经很好地融入了我们生活和社会的方方面面。它们不可预测的性能和性能不当行为对使用计算机的所有领域的生产力、效率和利润产生不利影响。不幸的是，现有的多核系统在很大程度上是基于对单核系统的假设来设计的，即内核之间没有共享资源，即使内存系统（一个主要的性能和功耗瓶颈）是共享的。因此，许多核心系统非常容易受到拒绝服务、不可控、不可扩展和低性能的影响。为了实现多核心系统的高效和生产性使用，迫切需要设计确保高服务质量（QoS）、性能健壮性和可伸缩性的系统。本研究的重点是开发能够实现可扩展、可控和高性能多核存储系统的基础突破。它旨在改变多核处理器的设计范式，将共享资源中的QoS和可扩展性作为一流的设计目标，并教育未来的工程师将这些目标作为基本设计目标来设计系统。核心方法是开发硬件/软件协作技术，以便在内存系统和互连中实现灵活的QoS、分区和性能机制。该项目开发基础技术，目标是云计算、数据中心、客户端系统、移动系统和传感器环境中的广泛应用。预计本项目开发的研究思路将使可控、健壮、可用和高效的多核系统成为可能，使我们的日常生活更美好、更高效，并在绿色计算方面迈出一大步。
