  Description:
    PAPI is a library that provides access to hardware counters
    from C/C++ or Fortran.  Most calls have to do with reading
    the values of the counters from a running program, but there
    is one call (PAPI_flops) that makes it very easy to get MFLOP
    information.  There are several routines also available that
    return information about the hardware on which the program is
    running.
