.SH "NAME"
.PP
papi_cost - computes execution time costs for basic PAPI operations\&.
.SH "Synopsis"
.PP
papi_cost [\-dhs] [\-b bins] [\-t threshold]
.SH "Description"
.PP
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\&.
.SH "Options"

.PD 0
.IP "\(bu" 2
\-b < bins > Define the number of bins into which the results are partitioned for display\&. The default is 100\&.
.IP "\(bu" 2
\-d Display a graphical distribution of costs in a vertical histogram\&.
.IP "\(bu" 2
\-h Display help information about this utility\&.
.IP "\(bu" 2
\-s Show the number of iterations in each of the first 10 standard deviations above the mean\&.
.IP "\(bu" 2
\-t < threshold > Set the threshold for the number of iterations to measure costs\&. The default is 100,000\&.
.PP
.SH "Bugs"
.PP
There are no known bugs in this utility\&. If you find a bug, it should be reported to the PAPI Mailing List at ptools-perfapi@ptools.org\&.
