Group's OGSI.NET project pages. These pages provide information about
our OGSI.NET project and links to our software and installation instructions.
In short, OGSI.NET is a platform for grid computing on .NET and a bridge to
grid computing solutions on Unix machines. The latest release is
2.1.6. It includes a OGSI-compliant hosting container and many example
services and several clients including a graphical browser. In describing OGSI.NET, we start with some basic questions...|
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?
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.

Where can I get OGSI.NET?
The latest version of OGSI.NET is 2.1.7. It can be downloaded in two modules, the server module which has the OGSI.NET container and the client module which has the OGSI.NET graphical browser for accessing services running in the container and many other example clients. Both are now compatible with the final release of WSE 2.0 sp3 from Microsoft.

The development of OGSI.NET has greatly benefited from feedback and interactions with the GRASP team. We are extremely thankful for their comments and evaluation.
Simon Cox has used OGSI.NET in the GEODISE project to run CFD simulations as grid services.
