Congratulation to Morris and Johannes for having achieved to collect these Use Cases on Distributed Data Processing (Grids).
Concerning the Use Cases presented by EDGI (chapters 5, 6 and 7), I have directly :
- added, inside 'Use Case Situation Analysis', the list of relevant official or de facto standards.
- made cosmetic formatting changes.
For the other chapters, I have inserted comments were needed. The most important ones are :
- What are the software skills of users : Developers of the application which they use; Advanced users of the application; Users of a scientific grid portal or a workflow engine to launch something they do NOT know at all, but which should give them back useful scientific results; … ?
- Please provide the detailed sequence of interactions between the users and the Grid infrastructure. Preconditions, triggers and postconditions are also useful.
- Which parts of the scheduling are performed by the user, and which parts are performed by the Grid middleware (matching user requirements with resource capabilities) ?
- Please provide precise description of resources which are the boundaries of the Grid infrastructure(s), and whose interfaces are used by the Use Case.
- Is this really a requirement on Grid middleware, or rather a requirement on the Workflow engine ?
I have also updated the properties of the MS-Word document.
