papi_multiplex_cost − papi_multiplex_cost utility.

file papi_multiplex_cost.c

NAME

papi_multiplex_cost - computes execution time costs for basic PAPI operations on multiplexed EventSets.

Synopsis

papi_cost [-m, —min < min >] [-x, —max < max >] [-k,-s]

Description

papi_multiplex_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 on multiplexed eventsets. This information provides the basic operating cost to a user’s program for collecting hardware counter data. Command line options control display capabilities.

Options


	•		-m < Min number of events to test >
	•		-x < Max number of events to test >
	•		-k, Do not time kernel multiplexing
	•		-s, Do not ime software multiplexed EventSets
	•		-t THRESHOLD, Test with THRESHOLD iterations of counting loop.

Bugs

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@icl.utk.edu.
