Collaborative Research: II-New: Distributed Research Testbed (DiRT)

近年来，通过网格和云计算，分布式计算的重要性急剧上升，为越来越多的科学和商业用户增加了可用的计算能力。计算能力的增强导致用户产生的数据量急剧增加，需要对改进管理和访问分布式数据进行新的研究。这些收益还推动了对计算资源的高效调度和租赁的需求，以及使机器虚拟化中的当前工作适应分布式环境的需求。这些研究方向需要开发和评估计算、通信和存储成本的新模型，但现有的基础设施使模型评估变得困难或不可能，因为它们经常被其他研究人员使用。该项目通过为不同的研究人员提供一个分布式研究试验台(CRIP)来解决这些问题，在此基础上开发和评估新技术。组成试验床的集群位于芝加哥大学、佛罗里达大学、夏威夷大学、圣母大学和密西西比大学。与工作网格环境不同，我们拥有对硬件的完全低级控制，并且完全了解数据和计算的位置。我们将使用试验床来解决日益增长的分布式计算用户所面临的问题。由于高性能计算对现代科学的开展至关重要，该项目将对各种科学学科的研究和教育产生重大影响。

Through Grid and Cloud computing, the importance of distributed computing has risen dramatically in recent years, increasing the computational power available to a widening audience of scientific and commercial users. Gains in computing power have caused a drastic increase in the volume of data produced by users, requiring new research on improved management and access to distributed data. These gains also drive the need for efficient scheduling and leasing of computational resources and for adapting current work in machine virtualization to a distributed context. These research directions require the development and evaluation of new models for computational, communication, and storage costs, but existing infrastructure makes model evaluation difficult or impossible, since they are in constant use by other researchers.This project addresses these concerns by providing a diverse group of researchers with a Distributed Research Testbed (DiRT) on which to develop and evaluate new technologies. The clusters making up the testbed are located at the University of Chicago, the University of Florida, the University of Hawai?i, the University of Notre Dame, and the University of Mississippi. Unlike working grid environments, we have complete low-level control of the hardware and complete knowledge of where the data and computation are located. We will use the testbed to address problems faced today by the growing number of users of distributed computing. Because high performance computing is essential to the conduct of modern science, this project will have significant impact on research and education in a a wide variety of scientific disciplines.
