RE: [ogsa-bes-wg] Create a revised BES spec draft that reflects the decisions of the July F2F mtg
by Ian Foster 30 Aug '06

30 Aug '06

Marvin: David's proposal, which is realized in the current draft, is that we define BES to just have "GetStatus" and "GetProperties" operations (as well as CreateActivity etc.). We can then compose WS-Transfer operations or WSRF operations, if desired, in a particular BES implementation. This seems to me to be a really nice solution to the "problem" that we thought we had, in that it avoids the need for multiple renderings. The one tricky issue is the rendering of faults. In the current BES document, we use WS-BaseFaults. You report that the Microsoft WS team has problems with that. I don't think we should let this be a show stopper, as I don't think it is essential that we use WS-BaseFaults in BES. At the same time, WS-BaseFaults was introduced for a reason. Thus I'd like to propose that we proceed as follows: a) We set up a phone call with the Microsoft WS team and the WS-BaseFaults guys to talk this over, in case it turns out that we can in fact all agree that WS-BaseFaults is useful. b) In the (likely) case that the Microsoft WS team still doesn't want to see WS-BaseFaults included, we check with the BES team that it is ok to use a different fault model for the BES core vs. the specs that might be composed with the BES core, such as WSRF. Thoughts? Ian.

RE: [ogsa-wg] OGSA F2F meeting agenda on Sept. 14 & 15
by Marvin Theimer 29 Aug '06

29 Aug '06

Hi; I will only be able to attend the F2F meetings on Thursday as I have to be back in Redmond on Friday the 15th. I'd like to hold an HPC Profile session on Thursday, if possible. Parts of that session would very probably involve BES and JSDL matters as they relate to the HPC Profile. Thanks, Marvin. ________________________________________ From: owner-ogsa-wg(a)ggf.org On Behalf Of Hiro Kishimoto Sent: Tuesday, August 22, 2006 12:33 AM To: OGSA WG Subject: [ogsa-wg] OGSA F2F meeting agenda on Sept. 14 & 15 Hi all, GGF18 and back-to-back OGSA meeting are just around the corner and we need to finalize meeting agenda very soon. The following is current proposal and if you have any request or comment, please let me know ASAP. We will review and finalize meeting agenda at the upcoming Thursday call. Also, if you plan to come (or dial-in) but your name is not on the attendee list, please let me know. You should be on the list to enter facility. https://forge.gridforum.org/sf/go/wiki1555?nav=1 Thursday afternoon (2:30-6pm) * A joint EMS/Data session (Dave and Andreas, 1-2hr depending on people's availability) o Since many Data members will be leaving on Thursday it would be good to arrange some time early on Thursday. * Info Model (Ellen and Fred, 2H or half day) o agenda is overflow from work that will not get done during the 2 GGF sessions o first draft of base model objects for HPC/BES/JSDL o probably XQuery examples. Friday morning (8am-noon) * OGSA general session (Tom and Hiro, 2H) o OGSA direction and priority o document status review o winter F2F schedule o telecon schedule * JSDL session (Steve McGough, 1-2 hr) o Bashing out ideas for JSDL 2.0 Friday afternoon (1-4pm) * OGSA-DMI Update (Michel Drescher, 1hr) o This session is to update the OGSA-WG and all interested parties on the status of the OGSA-DMI work. It is expected that a first draft of the functional interface is drafted at GGF18. * OGSA-RSS (Donal Fellows, ??) o discuss the EPS and its relation to the rest of the EMS arch -- Hiro Kishimoto

call for implementers of the OGSA HPC Profile
by Marty Humphrey 28 Aug '06

28 Aug '06

Folks, As chairs of the OGSA HPC Profile WG, Marvin Theimer and I think that we're getting sufficiently close to having a profile defined that we'd like to issue the call for implementers of the OGSA HPC Profile. While there is clearly some more work to be done on the current HPC Profile draft (and the BES spec), we believe that certain ambiguities in the current HPC Profile can only be identified and resolved when parties try to get their implementations to speak with each other. We seek implementers to (a) help solidify the profile through direct interoperability testing, and (b) help define the compliance suite. Therefore, we encourage people interested in prototyping an implementation to email me (Marty Humphrey). The current version of the HPC Profile spec can be found at: http://forge.ggf.org/sf/go/doc13736?nav=1 Thanks a bunch! Marty Marty Humphrey Assistant Professor Department of Computer Science University of Virginia

v23 of BES draft
by Marvin Theimer 24 Aug '06

24 Aug '06

Hi; My apologies for getting this draft out so late -- it's been another week of "agenda bending interruptions". In any case, enclosed is a revised version of the BES draft that includes a full exposition of the extensible state model concept as well as a refactoring of the two port-types so that attribute information and its retrieval are now part of the BES-Factory port-type. This was in response to the decision that there should be a "sys admin" port-type and an "ordinary users" port-type and that obtaining information about the state of a BES and its activities is something that ordinary users do and not just sys admins. Marvin.

Hi; Apologies for not responding until now. I will try to cover the topic of WS-BaseFaults and potential alternatives on today's BES telecon call. I will also send out an email about the topic afterwards.
