70 : /* Overview of how the "auction" strategy works:
71 :
72 : In the perf and balanced strategies, as soon as a transaction
73 : arrives it becomes eligible for scheduling. The auction strategy
74 : runs periodic batch "auctions". Transactions that arrive during the
75 : period when the auction is running are not immediately eligible for
76 : scheduling. These become eligible for scheduling when the auction
77 : ends. The exception is bundles, which are immediately eligible for
78 : scheduling regardless of whether an auction is running or not.
79 :
80 : Therefore, pack can be in one of 3 states:
81 : - 1) No auction running. New transactions that arrive are added to
82 : the pending/penalty treaps, but are not eligible for scheduling
83 : until the start of the next auction.
84 : - 2) Auction running. New transactions that arrive are added to the
85 : next_auction treap, which means they are not eligible for
86 : scheduling. Transactions in the pending/penalty treaps at the
87 : time of the auction starting are eligible for scheduling
88 : throughout the auction.
89 : - 3) The final 10ms of the leader rotation. All transactions are
90 : eligible for scheduling immediately.
91 :
92 : Each auction is limited to its proportional fraction of the blocks
93 : total CU limit. auction_cu_limit is the total block CU limit cost
94 : that the current auction cannot exceed. This is the fraction of the
95 : slot time (leader_slot_end_tick-leader_slot_start_tick) that will
96 : have elapsed when the auction ends (now+auction_interval_tick)
97 : multiplied by the total block CU limit (slot_max_cost).
98 :
99 : Auctions are run back to back, every 50ms (auction_interval_tick).
100 : auction_next_tick is the tick at which the next auction is due to
101 : start. This is set to start of the current auction +
102 : auction_interval_tick. Note that bundles adjust this value, to
103 : try and synchronize the start of the auction with a "burst" of
104 : bundles. This is because bundles typically arrive in bursts, and we
105 : want the pack auctions to coincide with the auctions held in the
106 : bundle engine. Therefore, each bundle arrival sets
107 : auction_next_tick to 5ms after that bundle arrived, so that the
108 : auction starts once the current bundle burst has ended. The
109 : following limits apply:
110 : - auction_next_tick can't be less than 40ms after the previous
111 : attempt (auction_last_attempt_tick + auction_spacing_tick). This
112 : is so that a short pause within a bundle burst does not trigger
113 : a new auction.
114 : - auction_next_tick can't be later than 50ms after the previous
115 : attempt (auction_last_attempt_tick + auction_interval_tick).
116 :
117 : Pack moves between the states as such:
118 : - An auction begins when we are leader, and all of the following are
119 : true:
120 : - The current tick (now) >= auction_next_tick
121 : - The current tick (now) < auction_final_start_tick
122 : - The current block cost is less than the auction CU limit
123 : (auction_cu_limit). If the auction has exceeded the limit the
124 : attempt is cancelled, and tried again at the next
125 : auction_next_tick.
126 : Starting an auction means:
127 : - New transactions are held in next_auction and are not eligible
128 : for scheduling until the start of the next auction.
129 : - Transactions already in the pending/penalty treaps become
130 : eligible for scheduling.
131 : - An auction ends when we are leader, and one of the following is
132 : true:
133 : - The next auction is due (now>=auction_next_tick)
134 : - The current block cost has exceeded the auction CU limit
135 : (auction_cu_limit)
136 : - We are in the last 10ms of the leader rotation
137 : (now>=auction_final_start_tick)
138 : - The block ends for any other reason
139 : Ending an auction means:
140 : - Every transaction held in next_auction is moved into the
141 : penalty/pending treaps. New transactions are added to the
142 : penalty/pending treaps.
143 : - Transactions in the pending/penalty treaps are no longer eligible
144 : for scheduling, until the start of the next auction - unless
145 : we are in the final 10ms of the rotation.
146 :
147 : Note that none of the above applies to bundles, which are eligible
148 : for scheduling as soon as they arrive, on all execle tiles. */
