Interoperable Infrastructure

Interoperability between the platforms will be achieved by federating services using a combination of decentralised Gateways (disparate approaches) and services based on standardised interfaces (analogous approaches).

Interoperability areas:

• process state management assigning and conveying state information associated with long running processes using contextualised web services
• data processing and storage executing computational jobs, requesting data transfer and storage
• resource and capacity management deciding how to provision service considering service providers resource constraints
• resource discovery discovering information about available resources, services and data
• meta-scheduling determining where Grid tasks should run according to user specified constraints
• policy management initiating trust relationships, managing security policies, and maintaining access rights

BRIDGE Infrastructure

This work focuses on the development of interoperable Grid infrastructures (CNGrid , GRIA) supporting secure and managed distributed collaborations between Chinese and European industrial and academic communities, whilst satisfying the specific needs of the target application sectors for transparent access to Grid resources: distributed inter-domain workflows, meta-scheduling of data processing and storage tasks on different Grid infrastructures, monitoring and management of SLA, and policy management.
