papi_multiplex_cost - papi_multiplex_cost utility.

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.
