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


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


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.


-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 THREASHOLD, Test with THRESHOLD iterations of counting loop.


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 [at]
