Release Name: CSF 4.0.1
Notes: 1. Component Overview The Community Scheduler Framework 4.0 (CSF4.0) is a WSRF-compliant Grid level meta-scheduling framework built upon the Globus Toolkit ®. CSF provides interface and tools for Grid users to submit jobs, create advanced reservations and define different scheduling policies at the Grid level. Using CSF, Grid users are able to access different resource managers, such as LSF, PBS, Condor and SGE, via a single interface. 2. Feature Summary Features new in release GT 4.0: Nothing new since GT 3.2. Other Supported Features Submit, control and monitor jobs at a grid level. Create and manage advanced reservations at the grid level. Send job and advanced reservation operations to local resource managers. A plug in scheduler interface so that site and user specific scheduling policies can be implemented regardless of the underlying resource manager. Create queues of jobs, each with separately definable scheduling policies. Deprecated Features None. 3. Technology Dependencies CSF depends on the following GT components: Java WS Core Message-Level Security Delegation Service GRAM MDS - internal libraries CSF depends on the following 3rd party software. The dependencies only exist if there is a requirement to have CSF use an interface (RM Adapter or GRAM) to a local scheduler: LSF Some other batch scheduler supported by the GRAM interface. 4. Supported Platforms Tested Platforms for CSF Linux (RedHat 9.0)
Changes: Backward Compatibility Summary Protocol changes since GT version 3.2: The protocol has been changed to be WSRF compliant. There is no backward compatibility with the previous versions. API changes since GT version 3.2: As the factory pattern has been removed from Globus Toolkit 4, the CreateServiceObject() of the QueuingFactoryService, JobFactoryService, and ReservationFactoryService are removed. The user doesn't need to create a service instance as before, but instead the user creates a Resource by invoking createResource() of the QueuingService, JobService, or ReservationService. Exception changes since GT version 3.2: The exceptions from Globus Toolkit 3 that no longer exist have been changed to RemoteException. Schema changes since GT version 3.2: See Gram Schema changes to RSL on the WS GRAM Fact Sheet.
