Detailed Description

Counter that uses PAPI to measure different events.

This counter provides support for measuring various events using PAPI. The number and type of events is only limited by the hardware support.

The events are identified by their PAPI name passed at the constructor of the counter.

PAPI event names can be found using the papi_avail utility.

value_type stapl::papi_counter::stop ( void )

Stops the counter and returns the difference from start().
