2 © 2006 Open Grid Forum 2 OGF IPR Policies Apply I acknowledge that participation in this meeting is subject to the OGF Intellectual Property Policy. Intellectual Property Notices Note Well: All statements related to the activities of the OGF and addressed to the OGF are subject to all provisions of Appendix B of GFD-C.1, which grants to the OGF and its participants certain licenses and rights in such statements. Such statements include verbal statements in OGF meetings, as well as written and electronic communications made at any time or place, which are addressed to: the OGF plenary session, any OGF working group or portion thereof, the OGF Board of Directors, the GFSG, or any member thereof on behalf of the OGF, the ADCOM, or any member thereof on behalf of the ADCOM, any OGF mailing list, including any group list, or any other list functioning under OGF auspices, the OGF Editor or the document authoring and review process Statements made outside of a OGF meeting, mailing list or other function, that are clearly not intended to be input to an OGF activity, group or function, are not subject to these provisions. Excerpt from Appendix B of GFD-C.1: Where the OGF knows of rights, or claimed rights, the OGF secretariat shall attempt to obtain from the claimant of such rights, a written assurance that upon approval by the GFSG of the relevant OGF document(s), any party will be able to obtain the right to implement, use and distribute the technology or works when implementing, using or distributing technology based upon the specific specification(s) under openly specified, reasonable, non- discriminatory terms. The working group or research group proposing the use of the technology with respect to which the proprietary rights are claimed may assist the OGF secretariat in this effort. The results of this procedure shall not affect advancement of document, except that the GFSG may defer approval where a delay may facilitate the obtaining of such assurances. The results will, however, be recorded by the OGF Secretariat, and made available. The GFSG may also direct that a summary of the results be included in any GFD published containing the specification. OGF Intellectual Property Policies are adapted from the IETF Intellectual Property Policies that support the Internet Standards Process.

Two independent implementations are needed to validate. If changes are needed to the current CIM jobs model, then well make them and return them to DMTF for inclusion in a future version of CIM.

4 Basic CIM Job Element

5 © 2006 Open Grid Forum 5 Basic CIM Job A Job represents an executing unit of work. A Job is distinct from a Process in that a Job can be scheduled or queued, and its execution is not limited to a single system. ConcreteJob is the instantiable job class.

6 Processing & Jobs

7 © 2006 Open Grid Forum 7 Processing & Jobs Jobs can have Setting Data. JobSettingData represents job characteristics and scheduling information for a CIM_Job. The settings may be applied to a job handling Service, a JobQueue or other destination to which jobs are submitted, and/or to individual CIM_Jobs. The applicability of the settings are defined using the ElementSettingData relationship. Since the Settings may be defined in several contexts and applied to many types of elements, this class is defined as a subclass of SettingData, versus ScopedSettingData. JobDestination represents where a Job is submitted for processing. It can refer to a queue that contains zero or more Jobs. JobDestinations are hosted on Systems similar to the way that Services are hosted on Systems. Also, they may be enabled/disabled similar to Services. JobQueue holds the status and configuration of a job queue. Jobs are held on a queue and can move from queue to queue until being processed. QueueStatisticalData contains the statistical data of a JobQueue. An instance of this class is associated with a specific JobQueue using the inherited ElementStatisticalData relationship. JobProcessingStatistics class records the completion statistics (such as ElapsedTime) and other information for its associated Job. The class will be extended in a future release to include statistics regarding resource utilization. Note that there may be many instances of this class if the Job is recurring (i.e., if its JobRunTimes property is not 1).

8 Jobs2

9 © 2006 Open Grid Forum 9 Jobs2 BatchService is a service that provides support for processing BatchJob requests. The basic assumption of this model is that a BatchService accepts a BatchJob for processing via its BatchSAP (service access point). The Job is then placed on a BatchQueue (indicated by the QueueForBatchService association). A System takes Jobs from Queues (indicated by the ExecutionTarget association) and processes them. BatchSAP is the service access point for accessing a BatchService. The relationship between the access point and the service is described by instantiating the ServiceAccessBySAP association. BatchJobGroup describes a collection of BatchJobs that are logically grouped. Two grouping/scheduling concepts are modeled: (1) User grouping: Jobs are logically grouped by the user of the batch system to capture common characteristics. There is no sequencing relationship between the jobs belonging to the Group. The jobs are grouped using the MemberOfCollection association. (2) Job sequencing: An ordered collection of jobs is defined where the jobs are executed in sequence. This captures a simple sequencing relationship for a set of jobs, where the order is defined using the AssignedSequence property of the OrderedMemberOfCollection association. An individual BatchJob can belong to multiple batch job groups. \n" If possible, an instance of OwningCollectionElement SHOULD be created for this JobGroup. However, this association might not exist, given that collections of jobs can move between systems as they execute, and the lifecycle of the owning/controlling entity is not necessarily persisted for the total duration of the collection. However, this can be very useful information when available.
