Setting Data Count

Data Count
 is the number of data items generated and pushed through a graph.
For graphs where potential parallelism is apparent from topology, pushing a single item through the graph is enough to explore the parallelism of the graph.
However, for cases where the parallelism is not readily apparent, as with a node with an unlimited concurrency, pushing a single item through the node is not enough to explore parallelism. Therefore, to ensure the graph is saturated, you need to set data count:
  1. Open the
    Preferences
     windows.
  2. Go to the
    TBB
     category,
    Scalability
     tab.
  3. Change the default number of data items to the number of cores available on the system in the
    Data Count
     field, based on the topology of the graph and the type of nodes in the graph.
