The UNICORE Rich Client: Facilitating the Automated Execution of Scientific Workflows

Today, many scientific disciplines heavily rely on computer systems for in-silico experimentation or data management and analysis. The employed computer hard- and software is heterogeneous and complies to different standards, interfaces and protocols for interoperation. Grid middleware systems like UNICORE 6 try to hide some of the complexity of the underlying systems by offering high-level, uniform interfaces for executing computational jobs or storing, moving, and searching through data. Via UNICORE 6 computer resources can be accessed securely with different software clients, e.g. the UNICORE Command line Client (UCC) or the graphical UNICORE Rich Client (URC) which is based on Eclipse. In this paper, we describe the design and features of the URC, and highlight its role as a flexible and extensible Grid client framework using the QSAR field as an example.
