Port details

Input: Input

Contains the input layer(s) to be released in sequence.

Output: Output

Contains the released layer(s).

Parameter details

Method: Method

Valid Values: By Group,By Layer Default value: "By Group"

Specifies the release method to be used.

If the method chosen is 'By Group', then all layers belonging to a given group will be released to the output port. If the method chosen is 'By Layer', only a single layer will be released to the output port at any given time.

Details

The RELEASE module releases all incoming layers in sequence by layer or by group during batch execution. Release takes place during each model execution untill all groups or layers have been released.

The RELEASE module acts as a bridge from one submodel to another. In the presence of RELEASE modules, the following rules will apply during batch execution:

During release, the input port of RELEASE will be blocked disabling all preceding modules.
No modules that are forward connected to a RELEASE module with blocked input port are allowed to execute.
Once a RELEASE module releases all its input layers, its input port will be unblocked enabling all preceding modules.
RELEASE will release a single group or layer during each model run. It will generate as many model runs as the number of groups or layers at its input port.

The significance of these rules is that RELEASE modules can be used to embed a submodel into an existing model, where the submodel uses the incoming data from the model to establish its batch execution status. The RELEASE module acts as a batch run generator, transforming a set of incoming layers into a set of batch parameter sets. It allows the execution of the parent model to be suspended until the embedded module has completed its own batch execution.
