GridWay » GridGateWay

This component enables the remote access to GridWay's metascheduling capabilities through a WSRF interface. Not all the functionality is accessible this way (array jobs and workflows are not available), but in turn it provides an interface that can be used with globus clients (e.g. globusrun-ws), is accessible through globus APIs (java core, java CoG) and also can be put to work with the various workflow tools based on globus, like, for example, the one offered by java CoG (Karajan).

The advantages of this approach is that is permits the virtualization of a grid (accessible through the encapsulated GridWay) through a WS-GRAM service. The main feature of our model is the use of the WS-GRAM, MDS and RFT services to recursively interface to the services available in a Globus based grid. A WS-GRAM service hosting a GridWay meta-scheduler provides the standard functionality required to implement a gateway to a federated grid, therefore allowing for the creation of hierarchical grid architectures. Such a combination allows the required virtualization technology to be created in order to provide a powerful abstraction of the underlying grid resource management services. Such components are only a first step as other additional components for negotiation, service level agreement, accounting and billing may be required to deploy production-level utility solutions.
