FINAL CALL: OGSA 1.5 (Architecture and Glossary)
by Andreas Savva 11 Mar '06

11 Mar '06

Final drafts of the OGSA 1.5 documents ([Arch] and [Glossary]) are available on Gridforge. We'd like to submit both documents to the GGF Editor *after the March 8 (Wednesday this week) teleconference*. It's a short deadline but both drafts have been in a fairly stable condition for some time now. Also note that OGSA 1.5 is intended as a minor revision to OGSA 1.0 (GFD-I.30). Please comment on the list or at one of the calls this week. After submission to the GGF Editor these documents will go through a 30-day public comment period, so you will have further opportunities to comment.

Teleconference minutes - 8 March 2006
by Andreas Savva 09 Mar '06

09 Mar '06

Minutes attached. https://forge.gridforum.org/projects/ogsa-wg/document/minutes-20060308/en/1 OGSA Teleconference - 8 March 2006 ================================== * Participants Andrew Grimshaw (UVa) Hiro Kishimoto (Fujitsu) Fred Maciel (Hitachi) Andreas Savva (Fujitsu) Dave Snelling (Fujitsu) Ellen Stokes (IBM) Jem Treadwell (HP) Jay Unger (IBM) Minutes: Andreas Savva * Summary of Actions Actions: - Jay will look into IBM facilities in Almaden and Santa Theresa. - Hiro/Andreas to confirm whether the availability or not of the Fujitsu facility - Hiro to ask Ravi whether the Intel facility is available * March 6 minutes approved with no changes * April F2F update Discussed possible venues in the Bay area. There was a clear preference for doing the meeting in the Sunnyvale area. It is expected that the site can be confirmed next week. Group chairs should send agenda requests to Hiro. Marvin can probably attend for one day and Andrew would like to arrange that to be Tuesday or Wednesday so that Naming can also be discussed. Actions: - Jay will look into IBM facilities in Almaden and Santa Theresa. - Hiro/Andreas to confirm whether the availability or not of the Fujitsu facility - Hiro to ask Ravi whether the Intel facility is available * "Guidelines for Information Modeling for OGSA Resources" document review Agreed that in the future reviews documents should have line numbers turned on. (Especially early draft documents.) Section by section review, mainly concentrating on Hiro's comments sent to the list. ** Section 1 - 1.2) Title and contents do not match well. The content is along the lines of use cases. - It is an early draft and will be revised. - Need more description on how to do the rendering/data model. Three options were discussed: 1. Rendering as part of the interface specs 2. RM team draws up guidelines 3. DMTF does rendering It was agreed that 1 & 3 are viable options but 2 is not. Some concerns were also raised on the timeliness of option 3. For example it looks like the WS-CIM will take some time to complete. So option 1 might be better for GGF use. - The text under Figure 1 seems to be slightly out of sync with the example in Figure 2. The example should be showing an XML Schema rather than the representation of an instance. ** Section 2 Agreed with Hiro's proposal to re-organize the text to start from modeling and then move to CIM Profiling. In other words identify what is in the domain specific model, identify CIM portions and generate changes/extensions to CIM. In Section 2.1 OGSA resource is used in a different way from the Glossary definition. Fred will review the definitions and also use Jay's description of 'interesting level of resource' from the point of view of the different capabilities. ** Section 3 Section 3.2 describes 2 ways of doing the modeling work. Involving the RM team in each effort does not scale. So there is a clear need to get involvement from more DMTF experts. Ideally the option of involving the RM team should not even appear in the document but it is probably necessary during the spin up phase. Agreed to re-order the text to put the second approach first. State that it is 'preferred'. ** Section 4 Discussed the standardization process. - Should the documents be information or recommendation track? - Recommendation track may be better. Experimental may also be an option. - There is also a question of the document structure and whether the proposal to the DMTF should be a separate document that is referenced by the profile, or part of the profile. - One idea was to package everything together in one profile document, identify the changes to CIM and then summarize the proposed changes to CIM as an appendix. Doing so would provide the necessary context for the work when taking it to DMTF. - In the case of the JSIM change request the document produced within GGF was submitted with a cover document. - What is the interaction between the GGF and DMTF process? For example, what happens when a DMTF TC changes things in the original GGF document for incorporation into CIM. - Early participation or communication with DMTF WG/TC is important so they know a change request is going to be submitted and noone is surprised. - However even in the case of the JSIM proposal where the CGS WG already had a lot of participation from CIM experts there were changed made in DMTF. - It would make it harder to get buy-in from GGF WGs if their work is subject to modification by a process they have no control over. There should be one more section to cover OGSA interface documents. ** Other comments Should this document reference DSP1001 (profile specification usage guide)? - Probably need a simpler profile template that leads to simpler (shorter) profiles. - Ellen is doing the current work in the spirit of the template but tailored to the needs of GGF. - Security section: Change text to discuss 'secure management' and 'management of security' instead - There should be some description of the tools to be used. E.g., RSM, the Cisco tool for CIM profiling if appropriate, etc. * Webcast update - Jem reported that HP has no branding conditions on the slides etc. - April 26 1:30-3:30 EST is the candidate date. In practice presenters should be available from about 1pm. - Andrew Grimshaw agreed to be a presenter. - Dave Snelling may have a conflict that day. - The webcast preparation will be discussed at the F2F. - The latest slide deck is probably the one used for the IPSphere presentation and should be on gridforge. It needs to be updated--- at the very least to remove/reformat any animations. * OGSA 1.5 - no comments * Next call EMS Scenarios

Teleconference minutes - 6 March 2006
by Andreas Savva 07 Mar '06

07 Mar '06

Attached. https://forge.gridforum.org/projects/ogsa-wg/document/minutes-20060306/en/1 (Note that April 4-7 at the Bay area was chosen again for the April F2F.) -- Andreas Savva Fujitsu Laboratories Ltd Teleconference minutes - 6 March 2006 ===================================== * Participants Michael Behrens (R2AD, LLC) Hiro Kishimoto (Fujitsu) Fred Maciel (Hitachi) Tom Maguire (EMC) Andreas Savva (Fujitsu) Ellen Stokes (IBM) Jem Treadwell (HP) Jay Unger (IBM) Peter Ziu (Northrop Grumman) Minutes: Andreas Savva * Summary of Actions Action: Candidate hosts should check availability and facilities for F2F and report back on Wednesday's call Action: Jem will check whether there are any HP branding conditions (or formatting, logos, etc) to the webcast. Action: Hiro to add webcast preparation to the F2F agenda Action: Tom to do a final call for the WSRF BP on the list * Minutes of February 27 approved with no changes * OGSA-HPC design team update (as reported by Hiro) Marvin will be selecting a time slot for the design team teleconferences. Most of the discussion should be done on the mailing list, however. Marvin will join the April F2F by phone and may attend in person if the meeting is held on the West coast. * OGSA 1.5 (Arch and Glossary) status update Final call issued on the list. Deadline is Wednesday's teleconference in order to allow for any last minute changes and submission by the end of the week. * April F2F update Reviewed the survey results and weighted the merits and de-merits of various venues and dates. Re-selected April 4-7 at west coast (Bay Area) as the first choice. Possible hosts: - Hitachi America (Fred to check network connectivity) - IBM (at a choice of location in the Bay area) Action: Candidate hosts should check availability and facilities for F2F and report back on Wednesday's call * Webcast discussion Jem reported that HP can provide the facilities to do an OGSA webcast, including recording and archiving for later use. Features also include polls during the webcast, online chat, keeping track of number of people registering, attendind, how long they attended, etc. There are 3-4 available slots (2 hours long but can use a portion only) and depending on the date between 100-200 can participate. Participants dial in. A moderator controls the session, while people who login as presenters can control the slides. Slides must be static and should be sent in advance. Even if that was not the case it would be good to prepare and have the slides ready 1 week in advance. When scheduled HP will publicise it to other companies. It therefore has the potential to attract people that OGSA can not typically reach. So good preparation is needed. Considering the above, a date late in April is better to allow more time to prepare. The webcast preparation should also be added to the F2F agenda. Action: Jem will check whether there are any HP branding conditions (or formatting, logos, etc) to the webcast. Action: Hiro to add webcast preparation to the F2F agenda * WSRF BP status update Tom has done the edits necessary to bring the BP up to date with the OASIS Standard versions of WSRF. Action: Tom to do a final call for the WSRF BP on the list * Other business Jem has updated the front page of the OGSA-WG gridforge site with text taken from the charter. A table of already published documents may also be added. There was a discussion on whether it is worth waiting for the new version of gridforge or not. Hiro mentioned that the gridforge site may be upgraded before or at GGF17. The new site will also include a wiki. It is not clear yet whether some of the documents, e.g., glossary, should be made into wikis. (Do we want short, precise definitions as in the current document or more explanation, e.g., a page for each term?) * Wednesday call - Review information modeling guidelines (Fred) - Webcast update (Jem)

CFP: Special Session on "Service Level Agreements" at HPCC-06
by Benno Overeinder 06 Mar '06

06 Mar '06

Please accept our apologies for cross-posting. ********************************************************************** Call for Papers: Special Session on "Service Level Agreements" at HPCC-06 In distributed environments, applications often make use of pre-defined resources (and services) defined statically at the start of application execution. However, such resources may either not be appropriate or available every time execution is requested -- therefore requiring the use of a registry service to discover resources dynamically. It is also possible that resources may be owned by institutions/individuals within another administrative domain -- outside the direct control of the application manager. It is therefore necessary to make use of Service Level Agreements (SLAs) to provide the interface between application users making demands on resources, and resource providers determining what should be made available for external use. An SLA may define: (i) requirements that such an application would place on resources (and services) owned by another third party; (ii) check whether these requirements have been met during use. The complexity of an SLA can vary from a static description of resource names (specified in terms of IP addresses) to complex constraints defined as functions that can be evaluated at deployment time. The aim of this special session is to bring together researchers in high performance computing, networking infrastructure and application sciences to demonstrate how SLAs may be defined, managed, updated and used. The following topics provide some guidance on content appropriate for this special session: * Description techniques for SLAs * Static vs. dynamic SLAs * Validation techniques for SLA parameters * Matchmaking approaches for SLA comparisons * Discovering resources based on SLA descriptions * Comparison of SLA and policy descriptions * Penalty clauses for SLAs + legal issues * Managing user expectations via SLAs * SLA descriptions and Quality of Service * Multi-party SLAs * Aggregating multiple SLAs * SLAs in Virtual Organizations (both multi-party and multiple SLAs) * Negotiating SLAs dynamically * SLA-based co-scheduling and resource reservation * SLAs and Registry Services * SLA-based trust management SUBMISSION GUIDELINES Submissions must include an abstract, five to ten keywords, the e-mail address of the corresponding author and should not exceed ten pages including tables and figures. All paper submissions must already be formatted according to the guidelines for Lecture Notes in Computer Science (LNCS) and represent unpublished and original work. Manuscripts must be submitted in PDF format, usage of LaTeX as a document preparation system is strongly encouraged. Submission of a paper should be regarded as an undertaking that, should the paper be accepted, at least one of the authors will register for the conference and present the work. Submissions to HPCC-06 will be conducted electronically on the conference website. IMPORTANT DATES Paper submission: March 13, 2006 Acceptance notification: May 29, 2006 Camera ready version: June 26, 2006 Conference: September 13-15, 2006 PUBLICATION The accepted papers will be published in proceedings of the HPCC-06 conference by Springer's Lecture Note in Computer Science (LNCS).
