Abstract

Grid computing has gone through some generations and as a result only a few widely used middleware architectures remain. The Globus Toolkit is the most widespread middleware in most of the current production grid systems, but the LCG-2 middleware dominates in Europe. The paper describes a brokering solution that enables the interoperability of various Globus and LCG-2 based grids during the execution of workflow applications, and supports users to utilize computing and storage resources from multiple production grids by a single application. The development and execution of such applications can be managed by a Web-based Grid portal called P-GRADE Portal, and the brokering of the workflows is carried out by its integrated GTbroker and LCG-2 broker component.
