Collecting performance data

The profiler is called at the start (before) and end (after) of a function. The following information is passed to the profiler each time it is called.

• task identifier (task-name)
• function identifier (function-name)
• processing unit identifier (processing-unit-id)
• before/after indicator

When the profiler is called at the end (after) of the function the program performs the following actions:

• calculates the statistical data
• adds the data to the accumulated statistic record
• edits the data based on the trace level specified
• writes a readable performance record (or keeps it in memory).

For all record types, the data will be included in the performance record if the time is equal or greater than 0.01 sec.
