NAMEpapi_cost - computes execution time costs for basic PAPI operations.
Synopsispapi_cost [-dhs] [-b bins] [-t threshold]
Descriptionpapi_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.
· -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.
Bugs
There are no known bugs in this utility. If you find a bug, it should
