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.

NAME

       PAPI_flops -

       Simplified call to get Mflops/s (floating point operation rate), real and processor time.

SYNOPSIS

Detailed Description
       C Interface:
	   #include <papi.h>
	   int PAPI_flops( float *rtime, float *ptime, long long *flpops, float *mflops );

       Parameters:
	   *rtime total realtime since the first call
	   *ptime total process time since the first call
	   *flpops total floating point operations since the first call
	   *mflops incremental (Mega) floating point operations per seconds since the last call

       Return values:
	   PAPI_EINVAL The counters were already started by something other than PAPI_flops().
	   PAPI_ENOEVNT The floating point operations event does not exist.
	   PAPI_ENOMEM Insufficient memory to complete the operation.

       The first call to PAPI_flops() will initialize the PAPI High Level interface, set up the counters to monitor the PAPI_FP_OPS event and
       start the counters.

       Subsequent calls will read the counters and return total real time, total process time, total floating point operations since the start of
       the measurement and the Mflop/s rate since latest call to PAPI_flops(). 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_flops returns information related to theoretical floating point operations rather than simple instructions. It uses the PAPI_FP_OPS
       event which attempts to 'correctly' account for, e.g., FMA undercounts and FP Store overcounts, etc.
