Community Services

A NC Base Program Project

When users and high-end distributed services come together on the Grid, new challenges arise from dynamic resource fluctuation, shared ownership, and heterogeneity, to name a few. Hence, adaptation is required on many levels. Current practice leaves the problem of adaptation to the service provider; however, embedding adaptive code within services is an arduous task for the service provider. This project is developing re-usable middleware that simplifies this task for the service provider.

The goal is to develop flexible techniques and re-usable middleware in support of adaptive services that satisfies users, service providers, and the Grid community, and to validate this middleware by applying it to DOE-relevant services in Grid test beds.

The objectives of this project are

• Encapsulate this middleware within several adaptive service classes: adaptive resource providers (ARP), and adaptive Grid services (AGS)
• Develop algorithms/software for robustness of infrastructure itself, e.g. AGS
• Integrate best practice solutions for AAA into service model
• Evaluate middleware and DOE-relevant applications and services on Grid test bed.
