/* This example demonstrates how to create a variable load for operations.
- *
+ *
* We consider the following graph:
- *
+ *
* comm -> exec
- *
+ *
* With a small load each comm operation is followed by an exec operation.
* With a heavy load there is a burst of comm before the exec operation can even finish once.
