PAPI_num_cmp_hwctrs – Return the number of hardware counters for the specified component. SynopsisDetailed DescriptionPAPI_num_cmp_hwctrs() returns the number of counters present in the specified component. By convention, component 0 is always the cpu. On some components, especially for CPUs, the value returned is a theoretical maximum for estimation purposes only. It might not be possible to…

PAPI_multiplex_init – Initialize multiplex support in the PAPI library. SynopsisDetailed DescriptionPAPI_multiplex_init() enables and initializes multiplex support in the PAPI library. Multiplexing allows a user to count more events than total physical counters by time sharing the existing counters at some loss in precision. Applications that make no use of multiplexing do not need to call…
