If PAPI is installed in your system correctly, I think you can run the following (any of the following) commands to get a list of available events:

Code: Select all
papi_avail
papi_native_avail


Running the above commands (papi_avail) will give you short info on the events; which is very self-explanatory if you ask me except of course for some weird events. For those, you might want to consult the documentation.


Good luck,

In addition to the papi_avail and papi_native_avail utilities, you may want to use the papi_event_chooser utility that will tell you which events (preset or native events) can be counted together.
Usage: papi_event_chooser NATIVE|PRESET evt1 evt2 ...

The number of events that can be collected together varies from architecture to architecture.
