项目摘要

Recent advances in cloud computing have led to a wide adoption of virtualization techniques in modern computer systems which allow better utilization of computer resources. There is also a steady trend towards building future data centers and high-performance computers with a software-defined architecture. However, challenges remain in adopting virtualization in many critical domains. First, there still exists a large performance gap between virtualized and physical systems, especially for high-speed devices, scientific workloads and latency-sensitive applications. Second, performance isolation and resource elasticity are often contradictory goals under the current models, which leaves much of the economic benefit of virtualization unexploited. Third, the additional system complexity in virtualiation undermines stability and predictability. This research addresses these issues and seeks to improve the performance, cost-effectiveness, and predictability of virtualized systems. The research will be tightly integrated into teaching and further broaden its impacts through mentoring and recruiting minority students, and outreach activities in K12 schools.Specifically, this project will identify gaps in the existing abstractions that cause performance degradation, inefficiencies and unpredictability, as well as pinpointing the essence of current abstractions that has enabled isolation, modularity and portability. The project entails three research thrusts: First, it will design and implement augmented abstractions for various types of virtualized systems, including virtual machines, containers and virtualized networks, to bridge the semantic gaps. Second, it will leverage the augmented abstractions to design efficient, effective and elastic resource management schemes while retaining much of the benefit of the existing abstractions. Third, it will increase the understanding of abstraction in multi-tenant systems and apply the knowledge to studying the inefficiencies of conventional systems and guide the design of new abstractions in emerging architectures.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
云计算的最新进展导致现代计算机系统中的虚拟化技术广泛采用,从而可以更好地利用计算机资源。使用软件定义的体系结构构建未来数据中心和高性能计算机也有一个稳定的趋势。但是,在许多关键领域采用虚拟化方面仍然存在挑战。 首先,虚拟化和物理系统之间仍然存在较大的性能差距,尤其是对于高速设备,科学工作负载和对潜伏期敏感的应用程序。其次,在当前模型下,绩效隔离和资源弹性通常是矛盾的目标,这给虚拟化的经济利益带来了未能开发的许多经济利益。第三,虚拟化的附加系统复杂性破坏了稳定性和可预测性。这项研究解决了这些问题,并试图提高虚拟系统的性能,成本效益和可预测性。这项研究将通过指导和招募少数族裔学生以及在K12学校的宣传活动而将其进一步扩展到教学中,并进一步扩大其影响。具体来说,该项目将在现有的抽象中确定差距,从而导致绩效退化,效率低下和不可预测性,并指出具有隔离性,模态性和端口的当前抽象本质。该项目需要三个研究作用:首先,它将针对各种类型的虚拟化系统(包括虚拟机,容器和虚拟化网络)设计和实施增强抽象,以弥合语义差距。其次,它将利用增强的抽象来设计高效,有效和弹性资源管理方案,同时保留现有抽象的大部分好处。第三,它将增加对多租户系统的抽象的理解,并将知识应用于研究常规系统的效率低下,并指导新兴建筑中新的抽象的设计。该奖项反映了NSF的法定任务,并认为通过基金会的知识分子和更广泛的影响,通过评估来进行评估。
