Set the default counting granularity for eventsets bound to the specified component. More...
@par C Prototype: \#include <papi.h> @n int PAPI_set_cmp_granularity( int granularity, int cidx ); @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 @param cidx An integer identifier for a component. By convention, component 0 is always the cpu component.
|PAPI_EINVAL||One or more of the arguments is invalid.|
|PAPI_ENOCMP||The argument cidx is not a valid component.|
PAPI_set_cmp_granularity sets the default counting granularity for all new event sets, and requires an explicit component argument. Event sets that are already in existence are not affected.
To change the granularity of an existing event set, please see PAPI_set_opt. The reader should note that the granularity of an event set affects only the mode in which the counter continues to run.
