Set the default counting granularity for eventsets bound to the cpu component.
More...
- C Prototype:
- #include <papi.h>
int PAPI_set_granularity( int granularity );
- Parameters
-
-- | granularity one of the following constants as defined in the papi.h header file
- PAPI_GRN_THR – Count each individual thread
- PAPI_GRN_PROC – Count each individual process
- PAPI_GRN_PROCG – Count each individual process group
- PAPI_GRN_SYS – Count the current CPU
- PAPI_GRN_SYS_CPU – Count all CPUs individually
- PAPI_GRN_MIN – The finest available granularity
- PAPI_GRN_MAX – The coarsest available granularity

- Return values
-
PAPI_OK | |
PAPI_EINVAL | One or more of the arguments is invalid. |
PAPI_set_granularity sets the default counting granularity for all new event sets created by PAPI_create_eventset. This call implicitly sets the granularity for the cpu component (component 0) and is included to preserve backward compatibility.
- Example:
int ret;
fprintf(
stderr,
"PAPI library version mismatch!\n");
exit(1);
}
if (ret < 0) handle_error(ret);
if (ret !=
PAPI_OK) handle_error(ret);
if (ret !=
PAPI_OK) handle_error(ret);
Create a new empty PAPI EventSet.
