DESCRIPTION

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

OPTIONS

23       -b <bins>
24              Define the number of bins into which the results are partitioned
25              for display. The default is 100.
26
27
28       -d     Display a graphical distribution of costs  in  a  vertical  his‐
29              togram.

32       -h     Display help information about this utility.
33
34
35       -s     Show  the  number of iterations in each of the first 10 standard
36              deviations above the mean.
37
38
39       -t <threshold>
40              Set the threshold for the number of iterations to measure costs.
41              The default is 100,000.
