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
