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.

3. © 2008 Open Grid Forum 3 Agenda Why Standardize? Where are we now? Base use-cases Standards Realizing the use cases

4. © 2008 Open Grid Forum 4 Why Standardize? What is the value of implementing standards? For vendors meet customer demand for interoperability For developers leverage the expertise of other developers offer a choice of tools and platforms in order to speed implementations only need to support one integration interface For end-users reduce the costs and risks of adopting grid technology get insight into the best practices of the industry at large

5. © 2008 Open Grid Forum 5 Why Not Standardize? Standards are not always appropriate A technology might be “too new” you stifle innovation with standardization, which focuses on commonality A technology might be very niched defacto standards will emerge in this case

6. © 2008 Open Grid Forum 6 Where are we now? We have a sufficient corpus of specifications and profiles to realize (implement) identified use cases in computing and data. Customer (user) value of standards is increased when they permit interoperability between packages/systems/vendors and when concepts can be transferred from one system to another.

11. © 2008 Open Grid Forum 11 Simple HPC use case run myjob BES resource 0 BES resource 1 BES resource 2 A simple “run” command (not defined by OGSA) generates a JSDL document describing the application to be run, its resource requirements, file inputs and outputs, etc. It interacts securely with a set of predefined BES resources using the OGSA Basic Security Profile 2.0, authenticating the client to the BES resources and the BES resources to the client. Data publisher Windows JSDL can specify data staging Or use RNS/GFS file system WSI-BSP, X.509, etc BES/ Queue

16. © 2008 Open Grid Forum 16 Interop – it takes two Not only must the service present the right porttype – e.g., BES It must also understand and use the same security infrastructure – and not choke on the XML

17. © 2008 Open Grid Forum 17 Interop – it takes two One group or implementation inter-operating with itself is not interesting Why should two different infrastructures interoperate? maybe there is a need for interoperability within the infrastructure if multiple vendors solutions are deployed Why should grid middleware vendors bother to interoperate?
