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.
