Abstract

The most important recent development in Grid systemsis the adoption of the Web services model as its basic architecture. The result is called the Open Grid ServicesArchitecture (OGSA). This paper describes a componentframework for distributed Grid applications that is consistent with that model. The framework, called XCAT, is basedon the U.S. Department of Energy Common Component Architecture (CCA) but with an implementation based on thestandard Web Services stack. Using this framework, an application programmer can compose an application from aset of distributed components. The result is a set of WebServices that collectively represent the executing application instance. This paper describes the basic architecture ofXCAT and the design issues to be considered for a component to serve as both a CCA and Open Grid Service Infrastructure (OGSI) service.
