9.1. UML diagrams and other resources¶
This page presents the UML diagrams for the Ensemble Toolkit. Additional information to help understand the design of Ensemble Toolkit is also presented for interested developers.
9.1.1. Class Diagram¶
The following document describes the classes in EnTK, their data members and functional members.
9.1.2. Sequence Diagram¶
The interaction of these modules for one successful run of an application is described in the following figure:
9.1.3. State Diagram¶
The stateful objects Pipeline, Stage and Task undergo several state transition during the execution of a workflow. We document them in the following figure:
9.1.4. Events Recorded¶
Following is a list of events recorded in each module (in temporal order). These events can be used to profile durations between two events or a state and an event.
