Internet（以及新兴的计算网格）的复杂性和动态性要求中间件和应用程序能够适应资源配置和可用性的变化。然而，据我们所知，有没有模拟工具，支持动态网格软件（或网格资源）的行为进行系统的探索。我们描述了我们的愿景和初步努力，以建立工具，以满足这些需求。我们的微网格模拟工具使Globus应用程序能够在任意虚拟网格资源环境中运行，从而实现广泛的实验。我们描述了这些工具的设计，以及它们在微基准测试、NA并行基准测试和整个网格应用程序上的验证。这些验证实验表明，微电网可以匹配实际实验在百分之几（2%至4%）。
The complexity and dynamic nature of the Internet (and the emerging Computational Grid) demand that middleware and applications adapt to the changes in configuration and availability of resources. However, to the best of our knowledge there are no simulation tools which support systematic exploration of dynamic Grid software (or Grid resource) behavior. We describe our vision and initial efforts to build tools to meet these needs. Our MicroGrid simulation tools enable Globus applications to be run in arbitrary virtual grid resource environments, enabling broad experimentation. We describe the design of these tools, and their validation on micro- benchmarks, the NA parallel benchmarks, and an entire Grid application. These validation experiments show that the MicroGrid can match actual experiments within a few percent (2% to 4%).
