Red outlined area #1
You can use the critical path calculation functionality (turquoise box) to identify bottlenecks in the data flow. As a result of this feature, all nodes on the critical path are highlighted.

Zoom in the timeline to analyze a single frame execution in detail. The frame execution flow is the following:

For a Threading Building Blocks (TBB) flow graph, an external activity can be encapsulated in a predefined async node. This activity represents offloading work to an Accelerator (for example, FPGA, GPU). The beginning and end of this activity are displayed as green vertical lines in the timeline. You can find a single execution within a single frame for each CV algorithm (represented by the nodes CV serial, CV nested, CV async). CV nested represents a node with a nested TBB parallel for algorithm that consumes most of the CPU time on average.
