UNICORE – Globus: Interoperability of Grid Infrastructures

This paper describes software developed at the Research Centre Juelich to demonstrate the feasibility of Grid interoperability between UNICORE (Uniform Interface to Computer Resources) [1] and Globus [2] without changes to any of the systems. UNICORE user requests, like job submission, status query, and output retrieval had to be mapped to the corresponding Globus mechanisms. Another significant topic was the integration of the Globus security infrastructure into the UNICORE architecture. The functionality of this prototype has been demonstrated successfully on SC2001 in Denver. KEYWORDS
