Background technology
Along with computing technique, the continuous development of network technology and application especially in recent years, computation schema also changes constantly taking place, develop to client/server (Client/Server) pattern that with component technology and distribute objects technology is representative from early stage single main frame, main frame/terminal pattern, progressively formed client/network (Client/Ne twork) computation schema of service-centric again.Grid computing (GridComputing) is the client/network calculations pattern of a quasi-representative, its objective is and make all kinds of isomeries that are distributed on the network, autonomous resource carry out integrated, the shared and collaborative work of ability as required, form dynamic Virtual Organization, trusted resource tissue, the management and use in autonomous territory are striden in realization, improve the comprehensive utilization ratio of resource, satisfy effectively towards the complicated applications of internet demand, and finally realize the resource sharing of cross-domain application and integrated large-scale calculations ability and mass data processing.The final purpose of grid is to provide more resources, function and interactivity for scientific and technical personnel and domestic consumer.For further grid and user's distance, reduce the threshold that the user uses grid, need the access way of good client as gridding resource, farthest be the details of user's hide grid resource.Therefore, a major issue that becomes the grid application research field alternately of the ways of presentation of grid application and user and grid system.
Utilizing the computing node on the grid to carry out operation, is a typical scene of grid application.Under this scene, face following problem aspect representing in application:
(1) unify the description problem: multifarious grid application need represent operation input and output user interface (User Interface with a kind of uniform way, be called for short UI), the job description of different application need illustrate the demand of operation to resource with a kind of unified descriptive language;
(2) user capture problem: at first, the user can visit and use gridding resource in the mode of oneself being accustomed at any time and any place; Secondly, at present a lot of grid systems are all taked the mode of doing things in his own way, exploitation client separately, this has not only brought the duplication of labour, and each grid system can't unify visit, and these grids see it is grid internally, but sees from the outside and can be described as data silo group one by one;
(3) user uses problem: reduce the user learning cost, user interface is friendly naturally.
Represent a layer angle from grid, in the prior art, grid portal framework GridSphere provides a grid portal Development Framework, but using, each all need one of stand-alone development based on hyper text markup language/java server end page face (Hypertext Markup Language/Java Server Pages, abbreviation HTML/JSP) man-machine interface, extensibility and reusability are not high; The unified interface of computational resource (Uniform Interface to Computing Resource, be called for short UNICORE) client/grid programmed environment (Grid Programming Environment, abbreviation GPE) provides a flexible user-friendly client framework, concrete agreement and language that the hide grid technology is used, can give different grid middlewares by submit job, but the UNICORE framework is open inadequately, and client is too complicated huge, is unfavorable for quick development and application.
From the UI technical standpoint, in the prior art, but the expanded application SGML of Microsoft (ExtensibleApplication Markup Language is called for short XAML) adopts extend markup language (ExtensibleMarkup Language is called for short XML) to express UI.During operation, the XAML file is opened by running environment, plays up the interface with the interface assembly of Windows, and when incident took place, the button.onrelease of invoke user oneself (.NET program) possessed the support (operating system is built-in) of platform bottom.But have following defective for grid application represents: definition is complicated, is not suitable for describing the simple relatively grid application UI in interface; With the BOTTOM LAYER ENVIRONMENT tight coupling, be unfavorable for that play up and message trigger at the realization interface in isomerous environment.
