Performance Application Programming Interface

PAPI provides the tool designer and application engineer with a consistent interface and methodology for use of the performance counter hardware found in most major microprocessors. PAPI enables software engineers to see, in near real time, the relation between software performance and processor events.

In addition, PAPI provides access to a collection of components that expose performance measurement opportunites across the hardware and software stack.

Please submit questions about using PAPI by joining the ptools-perfapi mailing list or by emailing ptools-perfapi@icl.utk.edu.
