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. IPR Notices Note Well for OGF meetings 2

5 Interoperability Motivation

6 Interoperability Motivation (1)
More variety of resources Access to a broader variety of resources E.g. convenient usage of different types of resources (HPC / HTC resources) in mutliple infrastructures Consider a larger range of scales, many different HPC machines! Extending the functionality Smart way of extending the functionality of one infrastructure E.g. brokering mechanism in HTC vs. explicit choose of computing resources in HPC Enhanced Resource Utilization Better load-balancing between different kind of computing infrastructures and their resources Combine resources of different infrastructures for more realistic simulations 6

7 Interoperability Motivation (2)
Economic Considerations Economic way of synergetic development avoids duplicate technology development Save computational time on rare and costly HPC resources, E.g. perform smaller evaluation jobs on HTC infrastructures before going to ‘full-blown’ production runs on HPC infrastructures with large-scale resources After full-blown HPC production runs – scientists are able to run directly in turn HTC evaluation jobs Reduce the overal data size to be stored on storage systems (Future: Storage might becomes more expensive than flop/s) 7

14 Identified Basic Use Case

15 Basic Use Case – Part 1 WISDOM, VPH & other use cases have similiar approach Basic use case identified in production Grids is as follows: On behalf of an authorized user, … … a tool interrogates the information system (representing a grid or a single resource), locates an optimal execution resource,… … submits the job to the execution resource, … … which in turn interprets the submitted job description… … and locates and fetches the necessary input data … from a remote storage - … … also on behalf of the user. Attributes GLUE OGSA-BES JSDL GridFTP SRM Delegation 15

16 Basic Use Case - Part 2 Upon the completion, the newly created data is uploaded … … to a storage resource … where this user is authorized (as a member of a Virtual Organization), …registered in the necessary data indexing catalogs, … …and the job record is updated in the accounting … … and monitoring system…  Question is how they all can work correctly together?!

22 Summary Production Grid Infrastructure Interoperation
Many use cases that point to open problems / missing links The WISDOM Use Case Work towards the Virtual Physiological Human (VPH) Basic use case is already supported by many open standards, but not working directly together Missing links between various specifications, tunings necessary Refinements necessary for joint use of vertical plumbings (i.e. security/information) with horizontal services (BES, SRM,…) Infrastructure Interoperability Reference Model Initial input from GIN production experience and use cases Work in progress for PGI working group Benefits Effective use of both HTC and HPC application chains accross multiple existing infrastructures Support of multi-scale and mulit-physics applications 22
