在网格计算环境中，异构资源分布在多个虚拟组织中，这些虚拟组织可能具有不同的本地策略。因此，调度和资源管理在这种情况下是具有挑战性的任务。由于元调度器能够为最终用户提供一个虚拟化的资源访问接口，并为资源提供者和消费者执行全局策略，因此它在计算网格中扮演着越来越重要的角色。本文将讨论社区可持续发展框架4.0（CSF 4）的设计和实现。CSF 4是一个符合WSRF的社区元调度器，并作为GT 4的执行管理服务发布。使用CSF 4，用户可以使用可能属于不同域的不同本地作业调度器。此外，CSF 4也支持Pre-WS-WSDL协议，尽管它基于WSRF规范。因此，CSF 4可以部署在GT 4和GT 2混合网格环境中，这对于拥有遗留应用程序的用户来说非常方便。
In a grid computing environment, heterogeneous resources are distributed in multiple VOs which may have different local policies. Hence, scheduling and resource management are challenging tasks in this context. Since a meta-scheduler is able to provide a virtualized resource access interface to end users, and enforce global policies for both resource providers and consumers as well, it plays more and more important roles in computational grids. In this paper, the design and implementation of Community Scheduler Framework 4.0(CSF4) will be discussed. CSF4 is a WSRF compliant community meta-scheduler, and released as an execution management service of GT4. Using CSF4, the users can work with different local job schedulers, which may belong to different domains. Moreover, the Pre-WS-GRAM protocol is also supported by CSF4, although it is based on WSRF specifications. Therefore, CSF4 can be deployed in a GT4 and GT2 mixed grid environment, which is very convenient for the users who have legacy applications.
