PAPI
Description
The Performance API (PAPI) is a standard application programming interface for accessing hardware performance counters available on most modern microprocessors. PAPI provides two interfaces to the underlying counter hardware: a simple, high-level interface for the acquisition of simple measurements and a fully programmable, low-level interface directed toward users with more sophisticated needs.
For more information, see the PAPI home page.
