    What is Grid Computing? 

    Grid computing is a mechanism for collaboration and sharing across multiple administrative domains with first class support for site autonomy. Distributed resources, such as cycles, storage and information, can be accessed from and provided to any location in the grid.

    What is the Open Grid Services Architecture (OGSA)?

    The Open Grid Services Architecture (OGSA) represents a new vision of both the grid and web services. By defining standard communication protocols and formats, OGSA represents the means to build truly large-scale, interoperable grid systems. The OGSA Working Group in the Global Grid Forum produces a set of documents detailing this vision. The OGSA vision is being instantiated in the Open Grid Services Infrastructure (OGSI).

    What is the Open Grid Service Infrastructure (OGSI)?

    The Open Grid Services Infrastructure (OGSI) is a set of WSDL specifications defining standard interfaces, behaviors, and schema for grid computing consistent with the OGSA vision. These interfaces and behaviors define the Grid Service. The latest version of the OGSI Specification is available from the OGSI Working Group in the Global Grid Forum. The OGSI specification is being implemented on a number of different platforms including .NET (by this project), Java (GT3 from the Globus Project) and others.

    What value does OGSI add to Web Services?

    • The OGSI Specification defines a subset of the behaviors of web services that are relevant to grid computing. In a sense, the OGSI Specification and the OGSI Working Group are like the Web Services Interoperability Organization (WS-I), but concentrating on the standardization necessary to make truly large-scale grids possible. For example, OGSI defines a lifetime management interface for transient grid service instances.
    • OGSI defines the idea of transient, i.e. short-lived, services. For example, a computational job could be viewed as a service. Currently, web services do not support this notion.
    • The OGSI Specification defines a two-level naming scheme based on Grid Service Handles (GSHs) and Grid Service References (GSRs). Each GSH is a global identifier for a unique grid service instance for all time. While a GSH is global unique handle for a grid service, it does not contain all the (possibly) dynamic information needed to communicate with a client. OGSI provides for a GSH to be resolved into one or more GSRs which contain all the information needed to communicate with clients using one or more protocol bindings.
    • OGSI provides a model for accessing the internal state that a grid service chooses to publicly expose. The Service Data Element (SDE) model provides standard mechanisms for querying, updating and adding and removing data associated with each grid service instance.

    What is OGSI.NET?

    OGSI.NET is an implementation of the OGSI specification on Microsoft's .NET platform. It provides a container framework on which to do OGSI-compliant grid computing in the .NET/Windows world. However, the OGSI.NET project is committed to inter-operability with other OGSI compliant frameworks (such as the Globus Toolkit 3) which run primarily on Unix systems and so represents a bridge between grid computing solutions on the two platforms. OGSI.NET provides tools and support for an attribute-based development model in which service logic is transformed into a grid service by annotating it with meta-data. OGSI.NET also includes class libraries that perform common functions needed by both services and clients.
