NAME

       papi_cost - computes execution time costs for basic PAPI operations.

Synopsis

       papi_cost [-dhs] [-b bins] [-t threshold]

Description

       papi_cost is a PAPI utility program that computes the min / max / mean / std. deviation of execution
       times for PAPI start/stop pairs and for PAPI reads. This information provides the basic operating cost to
       a user's program for collecting hardware counter data. Command line options control display capabilities.

Options

       • -b < bins > Define the number of bins into which the results are partitioned for display. The default
         is 100.
       • -d Display a graphical distribution of costs in a vertical histogram.
       • -h Display help information about this utility.
       • -s Show the number of iterations in each of the first 10 standard deviations above the mean.
       • -t < threshold > Set the threshold for the number of iterations to measure costs. The default is
         100,000.

Bugs

       There are no known bugs in this utility. If you find a bug, it should be reported to the PAPI Mailing
       List at ptools-perfapi@ptools.org.
