网格已被提出作为一个有前途的面向服务的平台,用于日益复杂的协同计算。面向服务的网格平台通常是基于web的,其中参与者通过共享稀缺的基于web的计算/计算资源(WBCR)进行协作以实现共同目标。在跨边界网格环境中,有效地共享WBCR是一个具有挑战性的问题,特别是当这些资源同时受到静态和动态使用时。为了建立本文中描述的基于证书的使用策略,我们首先探索了一个工作流引擎驱动的基于soa的资源访问控制机制。然后,从资源共享的角度出发,针对SOA&EDSCCE(基于soa &引擎驱动的结构化协同计算环境)的具体项目,提出了一种基于控制原则和WBCR使用策略的基础架构,以促进其在网格环境下的协同计算。本文的主要贡献有两个方面:1)根据基于证书的使用策略,提出了基于工作流引擎驱动的soa WBCR共享机制;2)提出了基于WBCR共享机制的协同计算的具体基础架构。
The grid has been proposed as a promising service-oriented platform for increasingly complex cooperative computing. The platforms of service-oriented grids are often Web-based where participants collaborate to achieve a common goal by sharing scarce Web-Based Computational/ Computing Resources (WBCR). To share the WBCR effectively is a challenging problem in boundary-spanning grid environments, particularly when these resources are subject to both static and dynamic usage. To set up the certificate-based usage policy described in this paper, we first explore a workflow engine-driven SOA-based resource access control mechanism. Then, aiming at setting up a cooperative computing paradigm from the resource sharing perspective, an infrastructure derived from a specific project of SOA&EDSCCE (SOA-Based&Engine-Driven Structured Cooperative Computing Environment) is proposed for promoting its cooperative computing in grid environment based on the control disciplines and the WBCR usage policy. The main contributions of this paper are twofold: 1) a workflow engine-driven SOA-based WBCR sharing mechanism is presented in accordance with to the certificate-based usage policy; and 2) a specific infrastructure of cooperative computing is put forward for the collaboration based on the WBCR sharing mechanism.
