UC-EUMEDGrid-interoperability
From EGI Knowledge Base
Use Case title: Interoperability between different grid middleware (gLite-GTRS)
Short description:
Actors involved: gLite and GTRS developers and users
Related Requirement: gLite and GTRS infrastructures.
Pre-conditions: Both middleware available for the user community
Steps: The current evolution of Grids towards the interoperability is largely based on the deploying of peer-to-peer services. Once users have been authenticated by their “native” middleware, job submission and resource sharing between two different infrastructures is mostly a matter of having each service of the first one dialoguing with its corresponding one on the other side, with no need for any supervising agent. P2P techniques allow a great system expansion with only but a little service overhead. Therefore, the convergence of peer-to-peer (P2P) and Grid computing is a natural outcome of recent distributed systems philosophy and the P2P approach to the interoperability has been successfully adopted by other Grid projects leading to the concept of “inter-Grid”. The Tunisian National Grid (GTRS) is based on a P2P architecture, so its interoperability with the EUMEDGRID infrastructure has been targeted; this goal requires several interfaces that offer the exchange functions for the services that need to communicate each other.
Post-conditions: The realization phase of the interoperability between GTRS, and gLite, middleware of EUMEDGRID, consists of two sections integrating the passage and submission of works from the user-interface toward the GTRS workers. The foreseen solution rests on the configuration of a Super Working Node (SWN) integrating the services of the EUMEDGRID infrastructure and to recover works from the gLite Resource Broker (RB) and transfer them towards the GTRS coordinator.
Project(s) involved: Developments are committed to be compliant to the standards emanated by the Open Grid Forum (OGF). The newly services can be also help the adoption of new standards concerning unregulated matters.
