gLite is the Middleware of the EGEE project and is based on predecessors like EDG (European Datagrid) and LCG. It integrates tools from Condor and the Globus Toolkit.
The gLite based Infrastructure is used by different communities today mainly by High Energy Physics, Biomed, Earthscience, Fusion and Archeologie.
Glite Grid Middelware Services includes Security Services (Authorization, Authentication, and Auditing), Information & Monitoring Services (Information and Application Monitoring), Data Management (Metadata, File and Replica catalogue, Storage Element, Data Movement) and Workload Management Services (Workloadmanagement, Computing Element, Job Provenance, Packagemanagement).
(Open) EGEE Software Licence
In production in Deisa Grid.
Authentication is based on X.509 PKI infrastructure. Proxies can be delegated to a service that it can act on the users behalf and includes VO information.
Secure service management is done by VOMS.
Not supported
Next to facilitating computational resources sharing, gLite provides the functionality of a full data grid with distributed storage systems. Logical file system and Replica services.
The abstraction layer for disk or storage resources is the SRM
Esp. for Databases an Interface (AMGA) is available.
Glite provides a commandline interface and a direct API (Java, C++) to access the system.
On top of this the user communities have built their own comfortable access methods. There are for example different portals like Genius (based on Engineframe) or p-grade (based on Gridsphere).
