+ * time, in clock ticks, it should be triggered.
*
- * Several slots may be processed in one operation. If the number of
- * slots is greater that the wheel size, the wheel is only traversed
- * once,
+ * The 'pos' field of the wheel corresponds to current time of
+ * the wheel. That is, it corresponds to Erlang monotonic time in
+ * clock tick time unit. The 'pos' field of the wheel is
+ * monotonically increased when erts_bump_timers() is called. All
+ * timers in the wheel that have a time less than or equal to
+ * 'pos' are triggered by the bump operation. The bump operation
+ * may however be spread over multiple calls to erts_bump_timers()
+ * if there are a lots of timers to trigger.
*
- * The following example shows a time axis where there is one timeout
- * at each "tick", and where 1, 2, 3 ... wheel slots are released in
- * one operation. The notation "<x" means "release all items with
- * counts less than x".
+ * Each scheduler thread maintains its own timer wheel. The timer
+ * wheel of a scheduler, however, actually consists of two wheels.
+ * A soon wheel and a later wheel.
+ *
+ *
+ * -- The Soon Wheel --
+ *
+ * The soon wheel contain timers that should be triggered soon.
+ * That is, they are soon to be triggered. Each slot in the soon
+ * wheel is 1 clock tick wide. The number of slots in the soon
+ * wheel is currently 2¹⁴. That is, it contains timers in the
+ * range ('pos', 'pos' + 2¹⁴] which corresponds to a bit more
+ * than 16 seconds.
+ *
+ * When the bump operation is started, 'pos' is moved forward to a
+ * position that corresponds to current Erlang monotonic time. Then
+ * all timers that are in the range (old 'pos', new 'pos'] are
+ * triggered. During a bump operation, the soon wheel may contain
+ * timers in the two, possibly overlapping, ranges (old 'pos',
+ * old 'pos' + 2¹⁴], and (new 'pos', new 'pos' + 2¹⁴]. This may
+ * occur even if the bump operation doesn't yield, due to timeout
+ * callbacks inserting new timers.
+ *
+ *
+ * -- The Later Wheel --
+ *
+ * The later wheel contain timers that are further away from 'pos'
+ * than the width of the soon timer wheel. That is, currently
+ * timers further away from 'pos' than 2¹⁴ clock ticks. The width
+ * of each slot in the later wheel is half the width of the soon
+ * wheel. That is, each slot is currently 2¹³ clock ticks wide
+ * which corresponds to about 8 seconds. If three timers of the
+ * times 'pos' + 17000, 'pos' + 18000, and 'pos' + 19000 are
+ * inserted, they will all end up in the same slot in the later
+ * wheel.
+ *
+ * The number of slots in the later wheel is currently the same as
+ * in the soon wheel, i.e. 2¹⁴. That is, one revolution of the later
+ * wheel currently corresponds to 2¹⁴×2¹³ clock ticks which is
+ * almost 37 ½ hour. Timers even further away than that are put in
+ * the later slot identified by their time modulo the size of the later
+ * wheel. Such timers are however very uncommon. Most timers used
+ * by the runtime system will utilize the high level timer API.
+ * The high level timer implementation will not insert timers
+ * further away then one revolution into the later wheel. It will
+ * instead keep such timers in a tree of very long timers. The
+ * high level timer implementation utilize one timer wheel timer
+ * for the management of this tree of timers. This timer is set to
+ * the closest timeout in the tree. This timer may however be
+ * further away than one revolution in the later wheel.
+ *
+ * The 'later.pos' field identifies next position in the later wheel.
+ * 'later.pos' is always increased by the width of a later wheel slot.
+ * That is, currently 2¹³ clock ticks. When 'pos' is moved (during
+ * a bump operation) closer to 'later.pos' than the width of a later
+ * wheel slot, i.e. currently when 'pos' + 2¹³ ≥ 'later.pos', we
+ * inspect the slot identified by 'later.pos' and then move 'later.pos'
+ * forward. When inspecting the later slot we move all timers in the
+ * slot, that are in the soon wheel range, from the later wheel to
+ * the soon wheel. Timers one or more revolutions of the later wheel
+ * away are kept in the slot.
+ *
+ * During normal operation, timers originally located in the later
+ * wheel will currently be moved into the soon wheel about 8 to
+ * 16 seconds before they should be triggered. During extremely
+ * heavy load, the scheduler might however be heavily delayed, so
+ * the code must be prepared for situations where time for
+ * triggering the timer has passed when we inspect the later wheel
+ * slot, and then trigger the timer immediately. We must also be
+ * prepared to inspect multiple later wheel slots at once due to the
+ * delay.
+ *
+ *
+ * -- Slot Management --
+ *
+ * All timers of a slot are placed in a circular double linked
+ * list. This makes insertion and removal of a timer O(1).
+ *
+ * While bumping timers in a slot, we move the circular list
+ * away from the slot, and refer to it from the 'sentinel'
+ * field. The list will stay there until we are done with it
+ * even if the bump operation should yield. The cancel operation
+ * can remove the timer from this position as well as from the
+ * slot position by just removing it from the circular double
+ * linked list that it is in.
+ *
+ * -- At Once Slot --
+ *
+ * If a timer is set that has a time earlier or equal to 'pos',
+ * it is not inserted into the wheel. It is instead inserted,
+ * into a circular double linked list referred to by the "at
+ * once" slot. When the bump operation is performed these timers
+ * will be triggered at once. The circular list of the slot will
+ * be moved to the 'sentinel' field while bumping these timers
+ * as when bumping an ordinary wheel slot. A yielding bump
+ * operation and cancelation of timers is handled the same way
+ * as if the timer was in a wheel slot.
+ *
+ * -- Searching for Next Timeout --
+ *
+ * In order to limit the amount of work needed in order to find
+ * next timeout, we keep track of total amount of timers in the
+ * wheels, total amount of timers in the later wheel, total amount
+ * of timers in soon wheel, and the total amount of timers in
+ * each range of slots. Each slot range currently contain 512
+ * slots.
+ *
+ * When next timeout is less than the soon wheel width away we
+ * determine the exact timeout. Due to the timer counts of
+ * slot ranges, we currently at most need to search 1024 slots
+ * in the soon wheel. This besides inspecting slot range counts
+ * and two slots in the later wheel which potentially might trigger
+ * timeouts for moving timers from the later wheel to the soon wheel
+ * earlier than timeouts in the soon wheel. We also keep track
+ * of latest known minimum timeout position in each wheel which
+ * makes it possible to avoid scanning from current position
+ * each time.
+ *
+ * When next timeout is further away than the soon wheel width
+ * we settle for the earliest possible timeout in the first
+ * non-empty slot range. The further away the next timeout is, the
+ * more likely it is that the next timeout change before we
+ * actually get there. That is, a change due to another timer is
+ * set to an earlier time and/or the timer is cancelled. It is
+ * therefore in this case no point determining next timeout
+ * exactly. If the state should not change, we will wake up a bit
+ * early and do a recalculation of next timeout and eventually
+ * we will be so close to it that we determine it exactly.
