Hi Pete, Mike, Keisuke and all, Here are the minutes of the last teleconf on April 12. It is also available at Gridforge: https://forge.gridforum.org/projects/acs-wg/document/minutes-20050412/en/1 Please review it and point out where the record is not correct, if there is any. Thank you, Sachiko Wada ====================================================================== ACS Teleconference ----------------------------------------------------------------------- Date and Time: April 12 19:00-20:30 EST 2005 / April 13 8:00-9:30 JST, 2005 Participants: Keisuke Fukui (Fujitsu) Peter Ziu (Northrop) Michael Behrens (R2AD) Sachiko Wada (ASCADE) - minutes ------------------------------------------------------------------------ * Topics 1. F2F meeting Possible candidates are: * 2nd or 3rd week of May, except for 10 - 12. Waiting for Tom's input. 2. How does the Naregi PSE on-demand compilation model fit to the ACS and CDDLM? - ACS need not discriminate what is a source code from what is a binary. But ACS may provide a sort of attributes to categorize and classify the contents in the archive. - ACS's task is to provide a simple way to access files inside the archive, such as adding files to and retrieving files from the archive. And also security mechanism to assure the correctness of the signature is desired. - We need to keep discussion about whether ACS should support dynamic contents; for example, data cashing. Since dynamic data such as inputs/outputs of the calculation tend to be huge, they may be better to be stored in a separate repository. (But the original repository should have a reference to the dynamic data repository.) - A sophisticated mechanism for access control is needed. Who own and who can access the data? - We assume that each archive, not each file in the archive, has its own EPR. - We need to examine the CDDLM scenario in conjunction with the ACS repository and the Naregi PSE model. * Next Call Announced later.

For the WG draft of the ACS Spec.
by Keisuke Fukui 12 Apr '05

12 Apr '05

Folks, Even though we are waiting for the minutes of GGF13 ACS-WG sessions, I'd like to summarize our achievement at GGF13 and start discussion toward the creating the WG draft of the ACS specification by the next GGF14 in June. Through out the two sessions at GGF13, we successfully demonstrated demands and expectations on ACS. The NAREGI PSE, introduced at the first session, is among the promising embodiments of the ACS. We also saw the larger vision lying beyond the initial ACS spec. from the Pete's slides. We then proceed to create the WG draft of the spec. by the GGF14. To move this ahead, I am creating a note to start our activity hoping to post here by the end of tomorrow. I welcome your opinions and comments. If you have plans regarding to our activity, please feel free to express those and let us discuss. I appreciate your contributions to our dream. -Keisuke

Hi all, Here are the minutes of the telcon on 30 March. It is also available at Gridforge: https://forge.gridforum.org/projects/acs-wg/document/minutes-20050330/en/2 Please review it and point out where the record is not correct, if there is any. Notice: I've changed the next telcon date in the minutes according to the last post Keisuke's mail. # 4/20 EST is OK for me, Keisuke. Regards, Sachiko Wada ====================================================================== ACS Teleconference ----------------------------------------------------------------------- Date and Time: March 30 19:00-20:30 EST 2005 / March 31 9:00-10:30 JST, 2005 Participants: Keisuke Fukui (Fujitsu) Peter Ziu (Northrop) Michael Behrens (R2AD) Sachiko Wada (ASCADE) - minutes Apologies: Thomas Studwell (IBM) ------------------------------------------------------------------------ * Topics a) the new requirements from NAREGI PSE + Keisuke summarized some new requirements for ACS spec are mentioned in the GGF13 presentation at ACS #1 session, which include: - including source code to be compiled for each target platform at or prior to the deployment of the application. - storing compiled binaries for target platforms in the repository. - storing (caching) the input and output data pairs through the lifecycle of the multiple executions of the application. + Agreed that we need to discuss about the above more in detail. Below are some additional issues raised in the discussion. - If source code is dynamically compiled at runtime, who is responsible for assuring the compiler in place? - Since the data used in scientific calculation tend to be significantly large, repositories for dynamic data may be better if implemented separately from the ACS repository. + Actions - Study the presentation and point out more questions/observations. b) relationship to the deployment API and component model being discussed in the CDDLM-WG. + Keisuke reported that the CDDLM team is positive about seeking for collaboration with ACS. They were preparing three specifications to be completed and one of them was the deployment API, whose 'addFile' interface looks to be a candidate contact point with ACS, for example, "register" interface of ARI. We need to discuss about where the ACS interfaces should stand in the CDDLM's lifecycle model. + Agreed that we also seek for the collaboration with the CDDLM-WG. The ACS repository will make it easy to enable versioning and repeatable deployment. We need to learn their specs. + Actions - Study their specification and point out some questions/observations. c) collaboration with IUDD standardization group + Generic archive standard will be output from IUDD standardization and we agreed that grid specific archive format (AAF) will use IUDD as a framework. We need to discuss differences in requirements between IUDD(for generic use) and AAF(grid specific) and the way to utilize IUDD spec so that it is efficient for grid use. + Actions - Make clear our (grid) requirements for IUDD and discuss with IUDD team. d) recruiting involvement from the European communities. + Keisuke reminded us that one of the comments I got after the sessions is that we should seek for the participants from European Grid communities since they share a lot with our usecase and scope. We need a research on this possibility. UniGrid, EGEE, omii, and more... + We need researches on their activity to examine if there exists any possibility of collaboration or integration with our activity. It is expected to promote our activity. However, since we should first establish collaboration with NAREGI, CDDLM and SI. + Actions - Keep watching other activities which might have a potential relationship to ACS * Roadmap a) Working draft We need to move forward toward writing a work group draft, which is planned to be presented at GGF14 in the charter . b) implementation The Business Grid and NAREGI projects are expected to be implementation of ACS spec. To realize this, we should write up our specification quickly. On the other hand, since their products are rather large scale, so we may seek for some more concise implementations to refine our concept. * F2F meeting plan Not decided, but one possible candidate is: Date: 2nd week of May Place: Washington, DC Waiting for the response from Tom and other participants. * Next call Date(Pending): Apr 20 Wed 20:00 EST/Apr 21 Thu 10:00 JST # U.S. Daylight Saving time has started Apr 3.

GGF13 minutes
by Sachiko Wada 30 Mar '05

30 Mar '05

Folks, Here are the minutes of the ACS sessions at GGF13. Please review them and address your comments/observations, if any. I apologize for the late post. They are also available at Gridforge: https://forge.gridforum.org/projects/acs-wg/document/minutes_session-1/en/1 https://forge.gridforum.org/projects/acs-wg/document/minutes_session-2/en/1 Regards, Sachiko Wada GGF13 Application Contents Service (ACS) session #1 Date and Time: Mar. 14, 2005, 13:00 - 14:30 Place: Lotte Hotel Emerald Room 3 Lead: Keisuke Fukui (Fujitsu) Notes: Sachiko Wada (Ascade) ** Agenda - Opening salutation Introduction & note takers Agenda Bashing - "ACS introduction" by Keisuke Fukui of Fujitsu - Use cases and visions "NAREGI PSE and ACS" by Prof. Kawata of Utsunomiya university in Japan "Enterprise Grid Appliance Operating Environment" by Peter Ziu of Northrop "Business Grid Project" by Keisuke Fukui of Fujitsu ** Summary The session attracted about 30 people and succeeded to present the overall information to new comers to the session and share the current status of the WG, leaving the presentation about IUDD specification and the detailed planning to the next session. ** ACS overview Current status and history at GGF is presented by Keisuke. Below is questions and answers for the presentation. Q. What will and will not be defined in ACS? A. We will define archive format and repository architecture. We are not going inside of the archive and repository. There are some standards for each of the contents, and we are going to include those standards as time matures. Q. Has the milestone changed significantly since the last BOF session? A. No. The milestone presented is the one in the charter with updates to the past milestones. Q. Do you have any reference implementation? A. We have two candidates now. The Business Grid Project and NAREGI PSE. Q. Since this activity will require changes for CDDLM, will ACS change its spec as well? A. We have not yet decided anything. we are open to modification taking into consideration of CDDLM. ** NAREGI PSE The outline and possible relationship to ACS are presented by Prof. Kawata. Q. How do you determine the granularity of archive? Are mathematical libraries included in an archive? A. What should be included in archives depends on the situation or the Grid systems. We expect ACS to have flexibility as to what the IT resources in the Grid system should provide. Q. What extent is the definition of ACS(NAREGI PSE?) service? Do you have schema? A. We already have some schema taken from the Business Grid Project. We expect collaboration with SI, which has comprehensive schema already. So we are planning to integrate these schemas. SI scope seems to be larger than us. SI can handle Grid applications but not limited to the Grid. They are trying to accommodate every software in a single standard. ACS archive schema could be one part of that, specific to Grid applications. ** Grid appliance usecase (presented by Peter Ziu) The future vision of the ACS, OGSA and beyond is explained. No questions. ** Business Grid Project (presented by Keisuke Fukui) Q. Do the three companies share development outcomes? Are you also going to share IT resources in data centers? A. Business Grid Project is an experimental project to develop a new framework for system management, and thus we are currently working very closely to create a single Grid Middleware. As for a commercially- operating data center, we have not yet discussed about operating a single or multiple data centers running that Grid Middleware. Q. Do people working in Business Grid Project agree that ACS will provide this capability? A. The Business Grid middleware is now under development at their last stage. We are talking closely so that two won't conflict with each other. We may refactor the ACS spec. or request modifications of the implementation if it is appropriate. Q. Is the solution provided by the Business Grid Project independent of ACS implementation? A. We are inspired from the Business Grid Project and I'd like to keep close relationship with it. However, we are open to any discussion, since we are the wg in GGF. ** wrap up. We ran out of the time at the end and called for participation to the second session to join the detailed discussion of the ACS-WG activities in future. GGF13 Application Contents Service (ACS) session #2 Date and Time: Mar. 16, 2005, 11:00 - 12:30 Place: Lotte Hotel Onyx Room Lead: Keisuke Fukui (Fujitsu) Notes: Sachiko Wada (Ascade) ** Agenda - Opening salutation Introduction & note takers - Review of the fist session. - Use cases and visions "Installable Unit Deployment Descriptor" by Thomas Studwell (IBM) * "Installable Unit Deployment Descriptor" The outline and current status were presented by Thomas Studwell. Below questions and answered were exchanged during the presentation. Q. Do you have any plan to go inside the install artifact? A. No. The artifact is the one which is referenced from the IU and SI(IUDD) activity do not go inside itself. Q. Do you think you can have platform-neutral install artifacts? A. Currently it is assumed that the artifact itself is platform specific. A comment from Keisuke: Requirements for IUDD are very similar to those for ACS, which is expected to be a single standard for software installation. We hope Grid-specific features will be considered in the future IUDD standardization. Q. Are you going to plan for refactoring current IUDD spec? A. Yes. We are going to submit IUDD spec to a formal workgroup and develop a totally new spec. The new workgroup will consider all of the industry requirements. I expect that CDDLM, ACS, and any other interested workgroups that need standard deployment descriptor to share the specification. I expect contributions both from implementation perspective from the participants. * ACS specification The strawman specification is introduced to show what we have today. We are going to have a single document that specify the ACS, as a WG draft after the WG discussion by the GGF14 in June. - table of contents - goals and non-goals * Wrap up A tentative roadmap is shown and agreed to discuss about how we proceed our activity through either e-mails, tele-conferences and/or face-to-face meetings.

Folks, We will have the ACS-WG#2 session tomorrow here, or tonight in U.S. Eastern time. This is an announcement how to join. ACS-WG#2: Mar 16 Wed 11:00 -12:30 (Korea) / Mar 15 Tue 21:00 - 22:30 (US-Eastern) The Onyx room assigned to the session has no equipment for a regular phone. Thus we will use the skype software to create a multi-point conference call. We will use glance software to share the screen of the presenter's pc. Presenters need install free glance software on their pc. Audience only need open url "acs.glance.net" and enter the key on any standard browser with Java enabled. I have tested with IE and Firefox. skype: I will create the conference session based on the skype account info for participants. Those who want to join the session needs to install skype software, create your own accounts and let me know it prior to the session. glance: url: acs.glance.net Key: 7777 (We may make last minute change. So keep watch.) FYI, here are urls to get each software, they are free. glance: http://www.glance.net/ skype: http://www.skype.com/ P.S. Tonight, I heard from Tom, a co-chair of this wg, that he will join the session remotely and give his presentation on solution installation, which was initially scheduled at ACS-WG#1. It's very good we can hear the latest update on it from him. -Keisuke
