A few thoughts emerged -following a quick read through. - -* ChangeActivityState -This reminded me of discussions we had in the late stages of BES. A similar operation was moved in & out of the draft before finally being -removed. There was discomfort as to the amount of influence an end-user agent could have on the underlying state machine. A user could not -force a job to execute if it was queued if there were not processes available. With the expanded state model that is now proposed
-scope for user control - fine. You have the notion of legal and illegal state change requests but I could not see these documented on the state -diagram. I would certainly propose changing this to 'RequestActivityStateChange' to make it clear that this is an initiation and
-some time for the underlying state engine to change. You effectively acknowledge this in your estimated time to change return value. - -I can see it being useful to have a 'this has already been done' option in the return body. I'm not sure how useful any value other than zero -effectively is here. To me you are effectively saying this has either been done or you need to set up a notification or a poll to check back to see -when it has completed. The estimate itself does not seem to be that valuable... - -* Partitioning -The three port types all seem sensibly scoped. I have great concerns about the AGU-JSDL section. I'm not sure if this is just a
Steven, all, first and foremost thank you for your valuable comments Steven. I put your comments in the working slides to be more effectively discussed and tracked. The discussion of this e-mail is on the agenda today.

-the moment. I would be VERY concerned if this AGU-JSDL forks away from the JSDL activity. JSDL has gained considerable traction and is -being further developed in the JSDL 2.0 discussions. I would have thought PGI would be better placed supporting a MINIMAL extension to -JSDL to support its immediate needs, and feeding the other improvements it could see being needed into the broader JSDL discussions. - -* Delegation & Information PortTypes -This must have broader use than just beyond PGI. If there are opportunities to do this why not put these into separate specifications even if -they are still done through the PGI-WG. - -Cheers, - -Steven - -Dr Steven Newhouse -EGEE Technical Director -Interim EGI.eu Director -Contact Details: http://cern.ch/Steven.Newhouse - - -> -----Original Message----- -> From: pgi-wg-bounces@ogf.org [mailto:pgi-wg-bounces@ogf.org] On Behalf -> Of Etienne URBAH -> Sent: 17 December 2009 23:33 -> To: Morris Riedel; pgi-wg@ogf.org -> Cc: edges-na3@mail.edges-grid.eu; lodygens@lal.in2p3.fr -> Subject: Re: [Pgi-wg] OGF PGI : Draft PGI Specification -> -> Morris and all, -> -> I have updated the 'Draft PGI Specification' with version 0.38 at -> http://forge.gridforum.org/sf/go/doc15839?nav=1 with following -> improvements : -> -> - Exclude internal states. -> -> - Second level Job states are also mandatory. -> -> - Inside the 'Submitted' state : -> - The Execution Service may already allocate resources, -> - Rename 'Waiting' substate as 'Validated', -> - Add 'Hold' substate. -> -> Best regards. -> -> ----------------------------------------------------- -> Etienne URBAH LAL, Univ Paris-Sud, IN2P3/CNRS -> Bat 200 91898 ORSAY France -> Tel: +33 1 64 46 84 87 Skype: etienne.urbah -> Mob: +33 6 22 30 53 27 mailto:urbah@lal.in2p3.fr -> ----------------------------------------------------- -> -> -> On Thu, 17 Dec 2009, Riedel, Morris wrote: -> > Hi team, -> > -> > here another update on one action item: -> > -> >> - A - action (Morris): copy strawman rendering doc to drafts -> > -> > Done. -> > -> > The actual draft specification (version 0.37) is now accessible in -> GridForge via: -> > Doucments - Root Folder - Drafts - Specification Direct link: -> > -> http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.pgi- -> > wg/docman.root.drafts.specification/doc15839 -> > -> > So far, I kept a copy within the Input Document Section since I -> propose a renaming of the document within drafts to: -> > -> > "Draft PGI Specification" -> > -> > It is neither a strawman document nor a concrete rendering - it's -> just a draft specification from PGI. -> > -> > However, of course, I seek to discuss this tomorrow in the telcon -> with all of you. -> > -> > Your co-chair, -> > Morris -> > -> > --------------------------------------------------------------------- -> - -> > -------------------------- -> > --------------------------------------------------------------------- -> - -> > -------------------------- -> > Forschungszentrum Juelich GmbH -> > 52425 Juelich -> > Sitz der Gesellschaft: Juelich -> > Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
