.SH NAME
PAPI_flips \-
.PP
Simplified call to get Mflips/s (floating point instruction rate), real and processor time\&.
.SH SYNOPSIS
.br
.PP
.SH "Detailed Description"
.PP
.PP
\fBC Interface: \fP
.RS 4
#include <\fBpapi\&.h\fP>
.br
int \fBPAPI_flips( float *rtime, float *ptime, long long *flpins, float *mflips )\fP;
.RE
.PP
\fBParameters:\fP
.RS 4
\fI*rtime\fP total realtime since the first call
.br
\fI*ptime\fP total process time since the first call
.br
\fI*flpins\fP total floating point instructions since the first call
.br
\fI*mflips\fP incremental (Mega) floating point instructions per seconds since the last call
.RE
.PP
\fBReturn values:\fP
.RS 4
\fIPAPI_EINVAL\fP The counters were already started by something other than \fBPAPI_flips()\fP\&.
.br
\fIPAPI_ENOEVNT\fP The floating point instructions event does not exist\&.
.br
\fIPAPI_ENOMEM\fP Insufficient memory to complete the operation\&.
.RE
.PP
The first call to \fBPAPI_flips()\fP will initialize the PAPI High Level interface, set up the counters to monitor the PAPI_FP_INS event and start the counters\&.
.PP
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 \fBPAPI_flips()\fP\&. A call to \fBPAPI_stop_counters()\fP will stop the counters from running and then calls such as \fBPAPI_start_counters()\fP or other rate calls can safely be used\&.
.PP
\fBPAPI_flips\fP 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\&.
