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 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 be reported to the PAPI Mailing List at [email protected].
