NAMEpapi_multiplex_cost - computes execution time costs for basic PAPI
operations on multiplexed EventSets.
Synopsis
papi_cost [-m, --min < min >] [-x, --max < max >] [-k,-s]
Descriptionpapi_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 THREASHOLD, 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@ptools.org>.
