Periods of computation and periods of inactivity in the execution of a program can be easily
identified using the Execution Flow view of the Profiling Tool.
Prerequisites:
To open the Execution Flow view:
Inactive periods are those with no active threads; on the graph, an inactive period is one with no colored bars. Read time (in seconds) along the right side. You can also see time in the status line.
Program shutdown would be indicated by the bottom of the bar corresponding to main--if the program was still being monitored.
To examine the flow of execution during computation, follow these steps:
