PAPI_ipc(3) PAPI PAPI_ipc(3)NAMEPAPI_ipc-
Get instructions per cycle, real and processor time.
SYNOPSISDetailed Description
C Interface:
#include <papi.h>
int PAPI_ipc( float *rtime, float *ptime, long long *ins, float
*ipc );
Parameters:
*rtime total realtime since the first PAPI_flops() call
*ptime total process time since the first PAPI_flops() call
*ins total instructions since the first call
*ipc instructions per cycle achieved since the previous call
Return values:
PAPI_EINVAL The counters were already started by something other
than: PAPI_ipc()
PAPI_ENOEVNT The total instructions or total cycles event does not
exist.
PAPI_ENOMEM Insufficient memory to complete the operation.
The first call to PAPI_ipc() will initialize the PAPI High Level
interface, set up the counters to monitor PAPI_TOT_INS and PAPI_TOT_CYC
events and start the counters. Subsequent calls will read the counters
and return total real time, total process time, total instructions
since the start of the measurement and the instructions per cycle rate
since latest call to PAPI_ipc(). A call to PAPI_stop_counters() will
stop the counters from running and then calls such as
PAPI_start_counters() can safely be used.
