Synopsis

14       papi_cost [-dhs] [-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       · -s Show the number of iterations in each of the first 10 standard
29         deviations above the mean.
30       · -t < threshold > Set the threshold for the number of iterations to
31         measure costs. The default is 100,000.

Bugs

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