Global

Global variables that are accessible across the graph may be added using the GlobalVariables construct. This is a construct that allows you to define an arbitrary number of parameters that may be accessed throughout the graph.

Use cases for the GlobalVariables construct include:

• Constant path names; for example, data-output directories (e.g. /scratch/pawseyXXX)

• Global iteration numbers; for example, to keep Loop iterations consistent throughout the graph.

Note

The GlobalVariable construct is replaced after translation. This means it cannot set values at runtime.
