Usage Example
To illustrate the functionality of the RDL service and client, a usage example is helpful.
This example outlines the typical usage of the service by one of BNL's remote
collaborators.
A researcher is designing an experimental analysis of a subset of the STAR data. He or
she picks an input dataset, which includes both files on disk and files extracted from a
data catalog. An application will be used to process the dataset. The application can be a
standard program or script, or custom software. Tasks also are defined for the application.
In this case, the researcher's application is Java, and the task is to run an algorithm
contained in a Java class. The researcher defines processing parameters, such as the
number of processing nodes to use (i.e., degree of parallelization), time and memory
constraints, and the output handling. Once the analysis is outlined, the researcher uses a
client tool to create the request. The GUI client's user-friendly point-and-click interface
can be used to define the request, or the request XML may be manually edited using a
text or XML editor.I'
