The + * time unit used is ERTS specific clock ticks. A clock tick is + * currently defined to 1 millisecond. That is, the resolution of + * timers triggered by the runtime system is 1 millisecond. * - * Timeouts kept in an wheel.

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.
