HPL_timer(3) HPL Library Functions HPL_timer(3) NAME HPL_timer - Timer facility. SYNOPSIS #include "hpl.h" void HPL_timer( const int I ); DESCRIPTION HPL_timer provides a "stopwatch" functionality cpu/wall timer in sec- onds. 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 dis- enabled 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 func- tionality, one must have called HPL_timer_boot() prior to any of the func- tions mentioned above. ARGUMENTS I (global input) const int On entry, I specifies the timer to stop/start. SEE ALSO HPL_timer_cputime (3), HPL_timer_walltime (3). HPL 2.3 December 2, 2018 HPL_timer(3)
