Moreno, Aleksandr and all, PGI Job State Model ------------------- Taking into account the remarks, comments and suggestions of the telephone conference of last week Wednesday 08 July 2009, I have performed following improvements to my Job State Model : - Group 'Hold-*' substates inside second level 'Hold' substates, - Add a third level 'Suspended' substate inside each 'Hold' substate, - Clearly separate 'Finished', 'Failed' and 'Cancelled' states, - Add an 'Automatic Resubmission' transition to the 'Submitted' state only from the 'Failed' state Concerning the possibility of 'transitions between substates' proposed by Aleksandr KONSTANTINOV in his mail dated 08 July 2009 : Even if a given implementation uses direct transitions between substates belonging to different states, - It would NOT be easy to agree on any standard for such transitions, - It would NOT be a good idea to force all implementations to simply understand them, - It would NOT be easy to write clients able to understand them, - For the normal flow, I have already designed : - the 'Outgoing' final substates as standard exit doors, - the 'Incoming' substates as standard entrance doors and branching points. So, I fully agree with Andrew GRIMSHAW, we should NOT expose transitions between substates belonging to different states. I have updated accordingly and uploaded inside GridForge following documents : - 'PGI Job State Model - Textual description' available at http://forge.gridforum.org/sf/go/doc15697?nav=1 - 'PGI Job State Model (available as ZARGO, XMI and PNG)' available under 5 formats at http://forge.gridforum.org/sf/go/doc15655?nav=1 : - ZARGO file created by ArgoUML - XMI file readable by any UML tool - PNG drawing of the Small Diagram - PNG drawing of the Big Diagram - PNG drawing of the Big Diagram with Comments The model itself contains the whole information, smaller diagrams are easier to view and to print, bigger diagrams show more details. Please review this model carefully before this telephone conference, so that we can quickly point any remaining issue and reach a consensus : I will attend this telephone conference, but I will probably NOT be able to attend the telephone conference on Wednesday 22 July 2009. I am still ready for further improvements, and if necessary, I will be available for telephone conferences on Fridays at 16h. Status update on Security ------------------------- I propose that before this telephone conference, you carefully review my 'PGI Security Model' available at http://forge.gridforum.org/sf/go/doc15584?nav=1 That would permit us to quickly point any remaining issue and perhaps reach a consensus.
