papi_cost − papi_cost utility.

file papi_cost.c

NAME

papi_cost - computes execution time costs for basic PAPI operations.

Synopsis

papi_cost [-dhps] [-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 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.
	•		-p Display 25/50/75 perecentile results for making boxplots.
	•		-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 1,000,000.
