papi_cost(1) PAPI papi_cost(1)NAME
papi_cost - papi_cost utility.
papi_cost - computes execution time costs for basic PAPI operations.
papi_cost [-dhs] [-b bins] [-t threshold]
papi_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. This information provides the basic operating cost to a user's program for collecting hardware counter data. Command line
options control display capabilities.
o -b < bins > Define the number of bins into which the results are partitioned for display. The default is 100.
o -d Display a graphical distribution of costs in a vertical histogram.
o -h Display help information about this utility.
o -s Show the number of iterations in each of the first 10 standard deviations above the mean.
o -t < threshold > Set the threshold for the number of iterations to measure costs. The default is 100,000.
There are no known bugs in this utility. If you find a bug, it should be reported to the PAPI Mailing List at email@example.com.

PAPI_add_named_event(3) PAPI PAPI_add_named_event(3)NAME
add PAPI preset or native hardware event by name to an EventSet
SYNOPSIS Detailed Description
@par C Interface:
int PAPI_add_named_event( int EventSet, char *EventName );
PAPI_add_named_event adds one event to a PAPI EventSet. @n
A hardware event can be either a PAPI preset or a native hardware event code.
For a list of PAPI preset events, see PAPI_presets or run the avail test case
in the PAPI distribution. PAPI presets can be passed to PAPI_query_event to see
if they exist on the underlying architecture.
For a list of native events available on current platform, run the papi_native_avail
utility in the PAPI distribution.
An integer handle for a PAPI Event Set as created by PAPI_create_eventset.
A defined event such as PAPI_TOT_INS.
The number of consecutive elements that succeeded before the error.
One or more of the arguments is invalid.
The PAPI library has not been initialized.
Insufficient memory to complete the operation.
The event set specified does not exist.
The event set is currently counting events.
The underlying counter hardware can not count this event and other events
in the event set simultaneously.
The PAPI preset is not available on the underlying hardware.
Internal error, please send mail to the developers.
* char EventName = "PAPI_TOT_INS";
* int EventSet = PAPI_NULL;
* unsigned int native = 0x0;
* if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
* handle_error( 1 );
* // Add Total Instructions Executed to our EventSet
* if ( PAPI_add_named_event( EventSet, EventName ) != PAPI_OK )
* handle_error( 1 );
* // Add native event PM_CYC to EventSet
* if ( PAPI_add_named_event( EventSet, "PM_CYC" ) != PAPI_OK )
* handle_error( 1 );
