Abstract

The invention discloses a management system of isomeric grid work flow which is based on virtual service, wherein a virtual information managing module is used to integrate service information of various isomeric grid, which provides virtual service information after being divided to a virtual service dispatching module, the virtual service dispatching module chooses correct service to carry on a grid platform in a virtual service group according to the input parameter which is provided by a work flow engine, and results are returned to the work flow engine, external data request is submitted to a virtual data center managing module, and virtual data address is exchanged to physical address by the virtual data center managing module, and results are deoxidized to virtual address and are returned after actual data are operated. The invention shields isomeric property of lower-layer grid platform through leading in the vertical service, and a work flow managing system is added in the choice and dispatching of the grid service, mutual operation of service resources among various isomeric grid platforms is achieved, and reliability and flexibility of the grid work flow managing system are improved.

Description

technical field

[0001] The invention belongs to the field of grid computing, and in particular relates to a heterogeneous grid workflow management system based on virtual services. Background technique

[0002] Grid is another major technological advancement after the Internet. In foreign countries, grid is often called "the next generation of World Wide Web". The fundamental feature of the grid is resource sharing and elimination of resource islands on the Internet. It connects and integrates geographically distributed and heterogeneous resources through a high-speed network to realize the comprehensive sharing of computing resources, storage resources, data resources, information resources, knowledge resources and expert resources. At present, the well-known grid platforms at home and abroad include GPE (German National Grid Platform), CGSP (China Education and Research Grid Platform) and GOS (Vega Grid Operating System), which are developed by different universities and ...

Examples

example

[0043] In order to verify the feasibility and effectiveness of the system of the present invention, the system of the present invention is configured in a real environment, and we manage the workflow of grid services under four heterogeneous grid platforms. The two grid platforms are built using the China Education and Research Grid Support Middleware CGSP, and the other two grid platforms are built using the GOS grid middleware developed by the Institute of Computing Technology, Chinese Academy of Sciences. The detailed test environment configuration is shown in Table 1.

[0044] After experimental testing, the following operations can be achieved:

[0045] (1) Include the services on the two grid platforms of CGSP and GOS in the workflow process. Realize transparent selection of heterogeneous grid services in workflow jobs.

[0046] (2) Update the service information on each grid platform, which can be reflected in the information center and virtual service group.
