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 users 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.
