NAME

       papi_cost - computes execution time costs for basic PAPI operations.

Synopsis

       papi_cost [-dhps] [-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.
       • -p Display 25/50/75 perecentile results for making boxplots.
       • -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 1,000,000.

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@icl.utk.edu.
