- * @class ACE_High_Res_Timer
- *
- * @brief A high resolution timer class wrapper that encapsulates
- * OS-specific high-resolution timers, such as those found on
- * Solaris, AIX, Win32/Pentium, and VxWorks.
- *
- * Most of the member functions don't return values.  The only
- * reason that one would fail is if high-resolution time isn't
- * supported on the platform.  To avoid impacting performance
- * and complicating the interface, in that case,
- * <ACE_OS::gettimeofday> is used instead.
- * The global scale factor is required for platforms that have
- * high-resolution timers that return units other than
- * microseconds, such as clock ticks.  It is represented as a
- * static u_long, can only be accessed through static methods,
- * and is used by all instances of High Res Timer.  The member
- * functions that return or print times use the global scale
- * factor.  They divide the "time" that they get from
- * <ACE_OS::gethrtime> by global_scale_factor_ to obtain the
- * time in microseconds.  Its units are therefore 1/microsecond.
- * On Windows the global_scale_factor_ units are 1/millisecond.
- * There's a macro <ACE_HR_SCALE_CONVERSION> which gives the
- * units/second.  Because it's possible that the units/second
- * changes in the future, it's recommended to use it instead
- * of a "hard coded" solution.
- * Dependend on the platform and used class members, there's a
- * maximum elapsed period before overflow (which is not checked).
- * Look at the documentation with some members functions.
- * On some (most?) implementations it's not recommended to measure
- * "long" timeperiods, because the error's can accumulate fast.
- * This is probably not a problem profiling code, but could be
- * on if the high resolution timer class is used to initiate
- * actions after a "long" timeout.
- * On Solaris, a scale factor of 1000 should be used because its
- * high-resolution timer returns nanoseconds.  However, on Intel
- * platforms, we use RDTSC which returns the number of clock
- * ticks since system boot.  For a 200MHz cpu, each clock tick
- * is 1/200 of a microsecond; the global_scale_factor_ should
- * therefore be 200 or 200000 if it's in unit/millisecond.
- * On Windows ::QueryPerformanceCounter() is used, which can be a
- * different implementation depending on the used windows HAL
- * (Hardware Abstraction Layer).  On some it uses the PC "timer chip"
- * while it uses RDTSC on others.
- * @note The elapsed time calculations in the print methods use
- * ACE_hrtime_t values.  Those methods do _not_ check for overflow!
- * @note Gabe <begeddov@proaxis.com> raises this issue regarding
- * <ACE_OS::gethrtime>: on multi-processors, the processor that
- * you query for your <timer.stop> value might not be the one
- * you queried for <timer.start>.  Its not clear how much
- * divergence there would be, if any.
- * This issue is not mentioned in the Solaris 2.5.1 gethrtime
- * man page.
- * A RDTSC NOTE: RDTSC is the Intel Pentium read-time stamp counter
- * and is actualy a 64 bit clock cycle counter, which is increased
- * with every cycle.  It has a low overhead and can be read within
- * 16 (pentium) or 32 (pentium II,III,...) cycles, but it doesn't
- * serialize the processor, which could give wrong timings when
- * profiling very short code fragments.
- * Problematic is that some power sensitive devices
- * (laptops for example, but probably also embedded devices),
- * do change the cycle rate while running.
- * Some pentiums can run on (at least) two clock frequency's.
- * Another problem arises with multiprocessor computers, there
- * are reports that the different RDTSC's are not always kept
- * in sync.
- * A windows "timer chip" NOTE: (8254-compatible real-time clock)
- * When ::QueryPerformanceCounter() uses the 8254 it has a
- * frequency off about 1.193 Mhz (or sometimes 3.579 Mhz?) and
- * reading it requires some time (several thousand cycles).
