Next Call

27 Jul '05

Hi team, Here is the proposed teleconference schedule from Keisuke. Next call: Apr 20 Wed 20:00 EST/Apr 21 Thu 9:00 JST If anyone has problems with this, please feel free to respond to this message. # Keisuke, let us know the calling info. By the way, I assume that we have agreed to cooperate to develop ACS specification but I don't think that we have agreed the process. I wonder how I can contribute to our work. We are going to write up a first working draft by GGF14, late June. It is about time to take some concrete actions. Deciding who writes which part of the document is one way, but there may be some issues left that need to be discussed before starting to write. If there are such issues I want to summarize them first. (Keisuke listed up such issues previously and we have already been discussing about Naregi requirements, but do they enough?) So, I'd like to hear your opinion about this at the next telconf. ... Does this make sense? Regards, Sachiko Wada

Folks, As you know, we are discussing to have the face-to-face meeting to prepare to generate the WG draft of the ACS spec. at GGF14 in late June. (See more details in tele-conference minutes.) Since we have two of the three co-chair and Mike on the U.S. East coast, we are planning to have it there and let others join in it over the phone. Current candidates for the dates are: - May 23rd-24th (First candidate) - May 30th-31st Above are chosen within constraints on our schedule and availability of meeting facilities. Our first choice would be May 23rd-24th. If you prefer another dates and/or can provide the facility, please let us know.

Hi all, Minutes of the last teleconf is attached. It is also available at Gridforge: https://forge.gridforum.org/projects/acs-wg/document/minutes-20050420/en/1 Please review it and point out where the record is not correct, if there is any. Regards, Sachiko ====================================================================== ACS Teleconference ----------------------------------------------------------------------- Date and Time: April 20 20:00-21:30 EST 2005 / April 21 9:00-10:30 JST, 2005 Participants: Keisuke Fukui (Fujitsu) Peter Ziu (Northrop) Michael Behrens (R2AD) Sachiko Wada (ASCADE) - minutes ------------------------------------------------------------------------ ** Topics * SUPerG Report by Mike Mike reported that he attended the SUPerG (Sun Users Performance Group), hosted by Sun Microsystems, and made a presentation associated with ACS. The conference was very interesting and he could get good feedback. ACTION: Send memo or something about the SUPerG to the mailing list. (Mike) * Date for F2F Candidate is May 23 - 24 (2 or 1.5 days). Pete will confirm whether Northrop can host the F2F meeting. NOTE: The proper date will be announced later from Keisuke. * Research updates on CDDLM, security, etc. - Mike have started research on security issues but not finished the task yet. - Pete read the CDDLM documents and had a few questions about their scope. - Sachiko also read the CDDLM documents and will report her understanding to the mailing list. - Keisuke and Sachiko had a meeting with Naregi team. They are going to join the next teleconference accepting our proposal. ACTION: Continue working on each research and make report. * Issues list We agreed to make more specific issues list about what we should/can do. For example, we need more persuasive use cases to explain the efficiency and necessity of ACS. We are going to use the gridforge tracker to maintain the list. Pete will take care of the tracker items to avoid redundancy between them. As for Solution Installation (IUDD), we need to change our document reflecting their spec, but since the activity has not started officially yet, we reserve this discussion. ** Next Call Date: Apr 27 Wed 20:00 EST/Apr 28 Thu 9:00 JST Calling #: will be announced later

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.
