HPL_ptimer(3)		     HPL Library Functions		 HPL_ptimer(3)

NAME
       HPL_ptimer - Timer facility.

SYNOPSIS
       #include	"hpl.h"

       void HPL_ptimer(	const int I );

DESCRIPTION
       HPL_ptimer  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_ptimer_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_ptimer calls in	them. HPL_ptimer_enable()  will	enable
       the  timer  functionality.  One	can retrieve  the current value	 of  a
       timer by	calling

       t0 = HPL_ptimer_inquire(	HPL_WALL_TIME |	HPL_CPU_TIME, I	)

       where   I   is the timer	index in  [0..64).  To	inititialize the timer
       functionality, one must have called HPL_ptimer_boot() prior to  any  of
       the functions mentioned above.

ARGUMENTS
       I       (global input)	       const int
	       On entry, I specifies the timer to stop/start.
