Abstract :
Most modern, high-performance processors have special, on-chip hardware that monitors processor performance. Data collected by this hardware provides performance information on applications, the operating system, and the processor. These data can guide performance improvement efforts by providing information that helps programmers tune the algorithms used by the applications and operating system, and the code sequences that implement those algorithms
