Interconnect EGEE and CNGRID e-Infrastructures through Interoperability between gLite and GOS Middlewares

Interoperability between the grid middlewares gLite, used in European grid infrastructure EGEE, and GOS, used in the Chinese grid infrastructure CNGRID infrastructure, is one of the main activities of the EUChinaGRID project. The EUChinaGRID project is an initiative, funded by the European Commission, to extend the European GRID infrastructure for e-Science to China. The first aim of EUChinaGRID is to facilitate scientific data transfer and processing in a first sample of scientific communities that have already strong collaborations between Europe and China. The interoperability between gLite and GOS middlewares and, then, the interconnection between EGEE and CNGRID infrastructures, is fundamental to achieve this goal. This paper presents the interoperability solution adopted by the EUChinaGRID project, including job submission, data transfer, and information services. The implementation of a gateway for achieving interoperability is discussed and preliminary results are presented.
