# PAPI\_flips(3)

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

## 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.

**PAPI\_flops()**

**PAPI\_ipc()**

**PAPI\_epc()**
