NAME
PAPI_set_granularity - Set the default counting granularity for eventsets bound to the cpu component.
SYNOPSIS
Detailed Description @par C Prototype: int PAPI_set_granularity( int granularity ); @param -- granularity one of the following constants as defined in the papi.h header file @arg PAPI_GRN_THR -- Count each individual thread @arg PAPI_GRN_PROC -- Count each individual process @arg PAPI_GRN_PROCG -- Count each individual process group @arg PAPI_GRN_SYS -- Count the current CPU @arg PAPI_GRN_SYS_CPU -- Count all CPUs individually @arg PAPI_GRN_MIN -- The finest available granularity @arg 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; // Initialize the library ret = PAPI_library_init(PAPI_VER_CURRENT); if (ret > 0 && ret != PAPI_VER_CURRENT) { fprintf(stderr,"PAPI library version mismatch!0); exit(1); } if (ret < 0) handle_error(ret); // Set the default granularity for the cpu component ret = PAPI_set_granularity(PAPI_GRN_PROC); if (ret != PAPI_OK) handle_error(ret); ret = PAPI_create_eventset(&EventSet); if (ret != PAPI_OK) handle_error(ret); * See Also: PAPI_set_cmp_granularity PAPI_set_domain PAPI_set_opt PAPI_get_opt Author Generated automatically by Doxygen for PAPI from the source code.
