HPL_timer HPL 2.2 Library Functions February 24, 2016
HPL_timer Timer facility.
provides a "stopwatch" functionality cpu/wall timer in
seconds. Up to 64 separate timers can be functioning at once. The
first call starts the timer, and the second stops it. This routine
can be disenabled by calling HPL_timer_disable(), so that calls to
the timer are ignored. This feature can be used to make sure certain
sections of code do not affect timings, even if they call routines
which have HPL_timer calls in them. HPL_timer_enable() will re-enable
the timer functionality. One can retrieve the current value of a
timer by calling
t0 = HPL_timer_inquire( HPL_WALL_TIME | HPL_CPU_TIME, I )
where I is the timer index in [0..64). To initialize the timer
functionality, one must have called HPL_timer_boot() prior to any of
the functions mentioned above.
I (global input) const int
On entry, I specifies the timer to stop/start.
