Large-scale computational resources are increasingly being delivered through distributed clusters of commodity workstations, which, when taken as a whole, provide the raw horsepower of traditional supercomputers at significantly reduced cost. Unfortunately, economic reality still dictates that large clusters must be shared across multiple, distinct applications, each with their own resource needs. This project focuses on designing and implementing an efficient management framework that enables the creation, allocation, and management of virtual clusters.A logical abstraction layered on top of a set of physical machines, virtual clusters harness virtual machine technology to more efficiently share computational resources between competingapplication demands while ensuring fault isolation. Critically, this proposal leverages the power of virtual machine monitors to provide novel functionality for an emerging class of applications. Inparticular, by exposing the dynamic levels of parallelism, dilating logical time, and supporting apparently infinitely large clusters, this work supports the distinctive needs of grid computing, network modeling, and Internet epidemiology.An output of this work will be a fully operational environment for managing cluster-based computational resources integrated with publicly available virtual machine technology. In addition to dynamically adjusting resources in response to changes in demand and application load, virtual clusters can instantly create clones of existing virtual machines, a functionality critical to the deployment of large-scale high-fidelity honeypots. Finally, the ability to slow down logical time within a virtual cluster---thereby speeding up the relative speed of network communication---enables the emulation of network links orders of magnitude faster than those typically available on commodity clusters.

大规模的计算资源越来越多地通过商用工作站的分布式集群提供，当作为一个整体时，这些工作站以显著降低的成本提供传统超级计算机的原始马力。不幸的是，经济现实仍然表明，大型集群必须在多个不同的应用程序之间共享，每个应用程序都有自己的资源需求。该项目致力于设计和实施一个高效的管理框架，支持虚拟集群的创建、分配和管理。虚拟集群是一组物理机之上的逻辑抽象，它利用虚拟机技术在相互竞争的应用程序需求之间更高效地共享计算资源，同时确保故障隔离。重要的是，该建议利用了虚拟机监视器的能力，为新兴的应用程序类别提供了新的功能。特别是，通过揭示并行性的动态级别、扩展逻辑时间和支持明显无限大的集群，这项工作支持了网格计算、网络建模和互联网流行病学的独特需求。这项工作的输出将是一个完全可操作的环境，用于管理集成了公共可用的虚拟机技术的基于集群的计算资源。除了根据需求和应用程序负载的变化动态调整资源外，虚拟群集还可以即时创建现有虚拟机的克隆，这是部署大规模高保真蜜罐的关键功能。最后，能够减慢虚拟集群内的逻辑时间-从而加快网络通信的相对速度-使网络链路的仿真速度比商用集群上通常提供的网络链路快几个数量级。
