Synopsis

14       papi_cost [-dhps] [-b bins] [-t threshold]
15

Description

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

Options

24       • -b < bins > Define the number of bins into which the results are
25         partitioned for display. The default is 100.
26       • -d Display a graphical distribution of costs in a vertical histogram.
27       • -h Display help information about this utility.
28       • -p Display 25/50/75 perecentile results for making boxplots.
29       • -s Show the number of iterations in each of the first 10 standard
30         deviations above the mean.
31       • -t < threshold > Set the threshold for the number of iterations to
32         measure costs. The default is 1,000,000.

Bugs

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