Does any one have the BES Document pen right now? If I don't hear from anyone by 2pm eastern tomorrow, I'll go ahead and take the pen and add the new "cleansed" wsdl and xsd to it. -Mark -- Mark Morgan Research Scientist Department of Computer Science University of Virginia http://www.cs.virginia.edu mmm2a(a)virginia.edu (434) 982-2047

All, I don't know if anyone is waiting - but the phone number I sent out is not good. ATT/UVA snafu. I will try and find another and mail it out, it may be a few minutes. A Andrew Grimshaw Professor of Computer Science University of Virginia 434-982-2204 grimshaw(a)cs.virginia.edu

Telecon today - 11 Eastern
by Andrew Grimshaw 22 Feb '07

22 Feb '07

All, Sorry for the delay getting the numbers out. Agenda: Get the fault issues settled - see extensive discussion in email Authorship - let's keep this short and punt it to the GFSG Resolve Andrea's comment on naming URI's - Address Joe Bester's comments: I don't think we will be able to get through all of these today. We will likely need to schedule another, hopefully last teleconference. Toll Free: 866-231-9615 Long Distance: 713-576-2028 Participant Code: 255921 Andrew Grimshaw Professor of Computer Science University of Virginia 434-982-2204 grimshaw(a)cs.virginia.edu

application profile proliferation
by Joseph Bester 21 Feb '07

21 Feb '07

I've been reviewing JSDL, the BES HPC Application Profile, and JSDL Parallel/SPMD profile to see how they can be used with Globus GRAM execution service. One concern I have is the way these various application profiles are redefining the same basic functionality (executable, arguments, environment, etc), either in their own namespaces or importing from the jsdl-posix namespace, sometimes with different behavior/features. It's not clear to me how (if at all) these are to be/can be composed. The feature set of GRAM seems to span these profiles: some (but not all) of the limits from POSIXApplication are relevant, as is the SPMD functionality of specifying the various process counts and something like SPMDVariation. There is also a small amount of scheduler- specific and site-specific extensions that GRAM might have to deal with. Do other groups have plans for implementing more than one of these profiles, and what approaches are you considering for doing so? joe

Telecon
by Andrew Grimshaw 20 Feb '07

20 Feb '07

All, I received four replies. Two of whom cannot make the time. Two on the west coast, one in the UK, and one in Japan (Andreas). Andreas said that he did not need to be on the call, but that he feels we need to address the issues he raised in email. The upside is we only need to schedule for two continents. But we do need a new time. Chris and Rich, can you make 11 am eastern, 8 am pacific on Thursday? Steve M., can you make 4PM UK?

Telecon time
by Andrew Grimshaw 16 Feb '07

16 Feb '07

All, As Stephen suggested we need to have a teleconference to come to closure on the document so we can send it for public comment. Finding a time slot is a problem - as many of us are already on several teleconferences that meet in the usual times. That time is driven by trying to get Asia/N. America/Europe/UK all on the phone at the same time. So, just to see if we need such a time slot, please let me know if you would like to attend the "come to closure" teleconference, and your continent/time-zone. Perhaps all continents do not want representation. If we do need to fit in all of the usual time-zones then I will suggest Thursday February 22nd, 4-6PM Central. (Our Thursday morning slot is now consumed by OGSA). Please advise me of your intent, restrictions, and level of commitment to be on the call.

Process issues
by Stephen M Pickles 14 Feb '07

14 Feb '07

All, One week last call on the OGSA-BES spec was announced about 10 days ago. This has sparked a flurry of interesting discussion. However, I think it time that the group try to reign in these discussions, and decide what if anything needs to be done to the document before submitting it to the OGF editor. I see some cause for urgency, as the OGSA-HPCP Profile specification, which references OGSA-BES, is already in GFSG review and on-track to emerge for public comment as a proposed recommendation in two weeks' time. The sub-threads I have noticed are: 1. A discussion about authorship and contributors, which should not be hard for grown-ups to reach closure on. Remember that the limit of 5 on authors is purely advisory. I recommend giving credit where credit is due, and if you still have more than 5 authors, submit anyway, making it the GFSG's problem, not the group's. 2. A discussion about the right granularity for BES faults. I don't detect any profound controversy here (just a bunch of smart people trying to get it right), but on the other hand, I don't detect a clear consensus on how to proceed. 3. Some arcane discussion, apparently stillborn, on Weak Similarity and the state model, which I don't presume to understand 4. A set of questions from Joseph Bester, of which some appear to have been answered, and some don't. May I suggest that the group has a call to try to close off these loose ends? And in the meantime, could anyone who still has issues with the current draft propose some concrete text? Stephen ==================== Stephen M.

BES Last Call
by Mark Morgan 14 Feb '07

14 Feb '07

Ladies and Gentlemen, As per consensus at the BES session yesterday, 1 February 2007, at 6pm at OGF19, I have made all noted modifications to the BES document. It is uploaded to the Gridforge website and is available as ogsa-bes-draft-v30. If you feel that you deserve acknowledgements for work done, or to be listed as an author, and you are not currently indicated properly in the document, please speakup. Once again, this is the last call for OGSA BES specification before we send it off for public comment. -Mark -- Mark Morgan Research Scientist Department of Computer Science University of Virginia http://www.cs.virginia.edu mmm2a(a)virginia.edu (434) 982-2047
