一种面向网格计算的计算经济及其在Nimrod-G资源代理中的实现
A Computational Economy for Grid Computing and its Implementation in the Nimrod-G Resource Brok
摘要：
计算网格，耦合地理上分布的资源，如个人电脑，工作站，集群，和科学仪器，已经成为下一代的计算平台，解决大规模的问题，在科学，工程和商业。然而，这些环境中的应用程序开发、资源管理和调度仍然是一项复杂的任务。在这篇文章中，我们将讨论我们的努力，在开发一个资源管理系统调度计算分布在世界各地的资源，不同的服务质量。我们的面向服务的网格计算系统称为Nimrod-G管理与远程执行相关的所有操作，包括资源发现，交易，基于经济原则和用户定义的服务质量要求的调度。Nimrod-G资源代理是通过利用Globus等现有技术实现的，并提供了构建工业强度网格所必需的新服务。我们讨论的初步实验结果调度一些参数计算使用Nimrod-G资源代理在一个世界范围内的网格测试平台，跨越五大洲。
英文摘要：
Computational Grids, coupling geographically distributed resources such as PCs, workstations, clusters, and scientific instruments, have emerged as a next generation computing platform for solving large-scale problems in science, engineering, and commerce. However, application development, resource management, and scheduling in these environments continue to be a complex undertaking. In this article, we discuss our efforts in developing a resource management system for scheduling computations on resources distributed across the world with varying quality of service. Our service-oriented grid computing system called Nimrod-G manages all operations associated with remote execution including resource discovery, trading, scheduling based on economic principles and a user defined quality of service requirement. The Nimrod-G resource broker is implemented by leveraging existing technologies such as Globus, and provides new services that are essential for constructing industrial-strength Grids. We discuss results of preliminary experiments on scheduling some parametric computations using the Nimrod-G resource broker on a world-wide grid testbed that spans five continents.
