Grid Scheduling Ontology Working Group (GSO-WG)

(Global Grid Forum, Scheduling and Resource Management Area; to be proposed to the GGF steering group)



NEWS:

20/09/2004, We are trying to arrange an ad hoc meeting during GGF12 in Brussels. Please check the mailing list and this web site for further news.

30/03/2004, Please check the meeting materials from our BoF session at GGF 10.

19/02/2004, A Grid Scheduling Ontology WG BoF is scheduled for GGF 10 on Wednesday, March 10, 2004, 3:30 - 5:00pm. Please join us at the Humboldt University, Berlin, room 2014B.

09/02/2004  After a period of silence we want to resume the work on the Grid Scheduling Ontology. It is planned to start again with a BoF to be held at GGF 10 in Berlin.

General working group information:

Chairs: Wolfgang Ziegler (Wolfgang.Ziegler@scai.fraunhofer.de), Philipp Wieder (ph.wieder@fz-juelich.de), nn
Mailing list: gso-wg@gridforum.org (Info about maillist and archives)

Charter:

Focus/Purpose:
This working group has the goal to produce an ontology of Grid Scheduling accompanied by a set of documents describing the ontology and the tools/libraries used to create the ontology and to make use of the ontology later.

Scope:
The ontology will be based on the Grid Scheduling Dictionary (GFD.11) developed by the Grid Scheduling Dictionary Working Group earlier.

Goals:
The working group will create an ontology of the Grid Scheduling domain supporting the scheduling of Grid resources done by local and distributed instances of software subsystems like schedulers, brokers or corresponding Grid services. The ontology created will provide the machine processable meaning of scheduling terms and conditions that is needed to negotiate service level agreements between usually heterogeneous systems operated at different independent sites. The working group will define usage and hierarchy of terms from the Grid Scheduling Dictionary (as specified in the Grid Forum Document GFD.11) thus helping to understand these terms and enable tool builders to incorporate the ontology into their tools. The ontology will overcome the shortcomings of a dictionary allowing classification of schedulers, reasoning about schedulers or mapping semantics of different scheduling systems for example. Using the ontology generated by the working group when designing and implementing the next generation of Resource Management Systems and their corresponding Grid services may further lead to ontology-driven systems.

The Grid Scheduling Ontology Working Group will establish a close collaboration with the Semantic Grid Research Group. While this research group addresses more general, long term research on the Semantic Grid, the Grid Scheduling Ontology Working Group will produce one concrete instantiation of an ontology. The Grid Scheduling Ontology Working Group will further collaborate with other working groups of the Scheduling and Resource Management Area, namely the Grid Resource Allocation Agreement Protocol Working Group and the Job Submission Description Language Working Group.

Documents:

The intermediate documents will be of class Informational (GWD-I), the final one will be of class Community Practice (GWD-C/GFD-C). Further information concerning the GGF documents provides the GGF documentation process.

Current documents:
20/09/2004, "Grid Scheduling Ontology - Objectives, context & usage scenarios" ().
30/12/2003, The revised draft charter (pdf).
04/02/2003, The draft charter (pdf).

Status:

30/03/2004  The first draft of the accompanying document "Grid Scheduling Ontology - Objectives, context & usage scenarios" will be soon available.

Milestones:

  • January 2004: Draft charter ready and posted to the GGF web site
  • GGF-10 WG meeting: Discussion of the charter; Presentation of a draft ontology and the tools used; Planning of follow-up steps
  • GGF-12 WG meeting: Integration of all terms selected from dictionary; Request for feedback
  • GGF-13 WG meeting: Demonstration of usage of the ontology
  • GGF-14 WG meeting: Grid Scheduling Ontology ready; Final document summarising and describing the ontology available; Description how the ontology may be used by resource management systems or services negotiating SLAs
