[Pgi-wg] PGI Job State Model for discussions (UML: zargo + xmi + png)

[Etienne URBAH]

Aleksandr,

Thank you very much for studying and criticizing my OGF PGI Job State 
Model (based on yours) :

I agree that a job 'failed because of failure detected during job 
processing/execution may lead to restartable job if reason of failure 
may be eleminated by user action.'

In that case, the job needs User action, so its state should be one of 
the following :
-  Pre-processing-Hold
-  Delegated-Hold
-  Post-processing-Hold

Besides, I suggest that when a User cancels a job which is NOT Hold, the 
Execution Service simply handles that as a job failure.  That permits to 
avoid 4 supplemental transitions toward Failed-Cancelled.

Please continue to criticize ...

Best regards.

    -  Pre-processing-Hold  includes Failed-Recoverable and Manual Stage-In.

    -  Delegated-Hold       includes Failed-Recoverable.

    -  Post-processing-Hold includes Failed-Recoverable and Manual 
Stage-Out.
