High Performance Software

PAPI

The PAPI Performance Application Programming Interface provides machine and operating system independent access to hardware performance counters found on most modern processors. Any of over 100 preset events can be counted through either a simple high level programming interface or a more complete low level interface from either C or Fortran.

Papi is not included in the default user path, but is available in the $PET_HOME/CE/pkgs/papi-x.x.x directory.
