Introduction
The Performance Application Programming Interface (PAPI) provides a standardized user level API for accessing processor and other system programmer counter information (such as instruction counts, cache misses, etc.).
PAPI details are provided on the PAPI Website.
PAPI on Theta
PAPI is available on Theta through the “papi” or “perftools-base” modules.
The preset and native events available on Theta may be listed by running the 'papi_avail' and 'papi_native_avail' utilities on a compute node via the qsub command. Accessing native events requires using the event names reported by 'papi_native_avail' as a string and converting them into an event code with the function PAPI_event_name_to_code().
