Deployment of CNGrid GOS

Prospects of CNGrid CNGrid will be connected to CNGI-a IPv6 network in China Multi-protocol support modification and upgrade of CNGrid GOS Transparent to applications CNGrid will become the basis of the network computing environment of China Regular operation It is very possible that CNGrid will be continually supported by 863 program

Interconnection of CNGrid and EU Grid Infrastructure Some issues has to be addressed for effective cooperation Precondition Reasonable network bandwidth Interoperability and inter-operation of European and Chinese Grid infrastructures Harmonization of the security mechanism Mutual interests in applications

Interoperability of CNGrid GOS and EU Grid software How to achieve interoperability of different Grid software Different software installation to the same infrastructure? How is it viewed by the applications?

Resource management and monitoring CNGrid has a resource monitoring system for management and scheduling Exchange monitoring information between different systems or using the same monitoring tool? How will the scheduling issue be handled?

Data access and Integration File and database level sharing OGSA-DAI? Other data grid software? Sharing data is crucial for research an other applications

User management Building and managing VOs Authentications Authorizations

Security Crucial for interconnection Harmonization of security polices and CA mechanisms

Accounting Setting up Grid business model Cost issues to be addressed Preparing for future Grid service business

User and development environment Portal based Integrated Grid programming and application development environment is required Application development support Service components Workflow

Deployment of Applications Deploy the current applications to other infrastructure Jointly developing and deploying new applications

Testing and training environment Setting up an environment for training and testing in parallel with operational infrastructure Interoperability testing Upgrading to Ipv6 Developing and testing new applications Providing training facility Less disturbance to the operational infrastructure

User training Tutorial on Grid software and tools Training and tutorial on applications Training technical support people

What we need to do for interconnection Supporting Grid software interoperability study, deploy different software in the environment Deploying current applications and developing an deploying new applications on extended infrastructure Supporting harmonized security mechanism Supporting testing and training

Thanks!
