NAME¶
papi_multiplex_cost - papi_multiplex_cost utility.
file multiplex.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 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.
