Version 7.1.0.0                                  Thu Dec 14 2023                                     PAPI_ipc(3)

CInterface:
           #include <papi.h>
           int PAPI_ipc(float*rtime,float*ptime,longlong*ins,float*ipc);

       Parameters*rtime realtime since the latest call
           *ptime process time since the latest call
           *ins instructions since the latest call
           *ipc incremental instructions per cycle since the latest call

       ReturnvaluesPAPI_EINVAL The counters were already started by something other than PAPI_ipc().
           PAPI_ENOEVNT The events PAPI_TOT_INS and PAPI_TOT_CYC are not supported.
           PAPI_ENOMEM Insufficient memory to complete the operation.

       The first call to PAPI_ipc() will initialize the PAPI 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 real time, process time, instructions and the IPC rate
       since the latest call to PAPI_ipc().

       PAPI_ipc() should return a ratio greater than 1.0, indicating instruction level parallelism within the
       chip. The larger this ratio the more effeciently the program is running. Note that PAPI_ipc() is thread-
       safe and can therefore be called by multiple threads.
