Balazs, Morris, Luigi, Johannes and all, Concerning the PGI Execution Service : Using ArgoUML and the agents defined in the 'Draft Specification Discussion Slides' of Morris, I have created 1 UML Sequence Diagram for each Job Vector Submission Use Case : - Quick Submission : 'PGI Job Vector Quick Submission Sequence Diagram (PNG)' at http://forge.gridforum.org/sf/go/doc15879?nav=1 - Submission With Full Validation : 'PGI Job Vector Submission With Full Validation Sequence Diagram (PNG)' at http://forge.gridforum.org/sf/go/doc15880?nav=1 Compared to the corresponding slide of Morris, my diagrams : - are created using UML, so they should be easily understandable by any computer engineer. - are printable, and can be included in a printable document. Therefore, I suggest to include my diagrams into the 'PGI Execution Service Specification'. So please take a look at them. The source UML file is 'PGI Execution Service : UML file (ArgoUML)' at http://forge.gridforum.org/sf/go/doc15878?nav=1 It contains : - The 'PGI Single Job State Model', with diagrams of various sizes, - A 'Collaboration Diagram', which shows the agents, but its graphical rendering is not very pretty, - The 2 Sequence Diagrams mentioned above. Besides, I have saved diagrams of the State Model with high resolution : - 'Big diagram' at http://forge.gridforum.org/sf/go/doc15881?nav=1 - 'Big diagram with comments' at http://forge.gridforum.org/sf/go/doc15882?nav=1 Let's talk at the telephone conference on Thursday 18 February 2010 at 15:30 CET.
