目前云上可用的计算资源量很大，并且可以通过按使用付费的成本模型轻松获得。需要按需执行的E-Science应用程序可以从云中受益，因为不需要获得永久的计算资源来支持峰值需求。在本文中，我们提出了AMOS，一个自动创建和管理云上的临时网格执行（部分）应用程序工作流程的系统。我们在研究网格和Amazon EC2云上使用AMOS和一个代表性的电子科学应用程序进行了实验。结果表明，AMOS是一种可行的方法来管理和执行e-Science应用程序在一个灵活的网格环境中，并探索新的机制，允许云资源的最佳利用。此外，我们认为AMOS作为一个（虚拟）基础设施，使网格应用程序在运行时控制其计算资源的操作系统的一步。
The amount of computing resources currently available on Clouds is large and easily available with pay per use cost model. E-Science applications that need on-demand execution benefit from Clouds, because no permanent computing resources to support peak demand has to be acquired. In this paper, we present AMOS, a system that automates creation and management of temporary Grids on a Cloud to execute (parts of) application workflows. We performed experiments with AMOS and a representative e-Science application on a research Grid and on the Amazon EC2 Cloud. The results show that AMOS is a viable approach to manage and execute e-Science applications in a flexible Grid environment and to explore novel mechanisms that allow optimal utilization of Cloud resources. Furthermore, we consider AMOS as a step towards an operating system for (virtual) infrastructures that enables Grid applications to control their computational resources at run-time.
