Overview
Most analytic routines (e.g. clustering, t-test etc.) available in geWorkbench are implemented directly in the geWorkbench desktop application code. They run on your local PC.
In cooperation with caBIG(R), the National Cancer Institute's Cancer Biomedical Informatics Grid program, a number of the geWorkbench analysis components have also been adapted to run as services on caGrid, the primary infrastructure component of caBIG. In accordance with caBIG principles, each has a well-defined object design and a public application programming interface (API) via which data can be exchanged. Annotations describing each service, object and parameter are stored in the caDSR (NCI's Cancer Data Standards Repository), using standard vocabulary terms available from the Enterprise Vocabulary Services (EVS).
Some services are implemented only remotely, such as Mark-Us, where the grid component serves as an interface to a web service.
Each geWorkbench analysis component that has an associated grid service will show a Services tab in the Analysis framework, adjacent to the Parameters tab.
Services tab
Local/Grid
Selects whether to run the analysis locally (within geWorkbench on the desktop) or on the grid.
Change Index Service
Index Services maintain lists of available grid services. geWorkbench is delivered with the URL of a Columbia Index Service preconfigured, which provides access to demonstration grid service implementations.
Change Dispatcher
The Dispatcher is a geWorkbench server-side component which provides connectivity between geWorkbench and caGrid. geWorkbench is delivered with the URL of a Columbia Dispatcher Service preconfigured.
