NAME¶
PAPI_flips - Simplified call to get Mflips/s (floating point instruction rate), real and processor time.SYNOPSIS¶
Detailed Description¶
C Interface:#include <papi.h>
int PAPI_flips( float *rtime, float *ptime, long long *flpins, float *mflips
);
Parameters:
*rtime total realtime since the first call
*ptime total process time since the first call
*flpins total floating point instructions since the first call
*mflips incremental (Mega) floating point instructions per seconds since
the last call
Return values:
PAPI_EINVAL The counters were already started by
something other than PAPI_flips().
PAPI_ENOEVNT The floating point instructions event does not exist.
PAPI_ENOMEM Insufficient memory to complete the operation.
The first call to PAPI_flips() will initialize the PAPI High Level
interface, set up the counters to monitor the PAPI_FP_INS event and start the
counters.
Subsequent calls will read the counters and return total real time, total
process time, total floating point instructions since the start of the
measurement and the Mflip/s rate since latest call to PAPI_flips(). A
call to PAPI_stop_counters() will stop the counters from running and
then calls such as PAPI_start_counters() or other rate calls can safely
be used.
PAPI_flips returns information related to floating point instructions
using the PAPI_FP_INS event. This is intended to measure instruction rate
through the floating point pipe with no massaging.
