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.
