Counters
Profiles
Display amount of time spent in different program components.
Application of sampling techniques.
Simple but not necessarily highly accurate.
Value of program counter is determined at fixed intervals.
Histogram of execution frequencies.
Advantages:
Automatic generation at low costs.
Small amount of data.
High-level view of program behavior.
Limitations:
No
temporal
aspects of execution.
First technique for seeking to understand parallel program performance.
