Allocating Information For Content Selection Among Computing Resources Of An Online System

摘要

When an online system receives a request to present content items to a user, a content selection system included in the online system selects content items for presentation to the user during a latency period from the time the request was received until the time when the content items are sent. A feedback control mechanism communicates with each computing device of the content selection system to determine the latency period of each computing device. The feedback control mechanism also determines a target latency period in which content items are selected. By comparing the latency period of each computing device to the target latency period, an amount of information to be evaluated by each computing device is determined based on whether a computing device's latency period is greater than or less than the target latency period.

1. A method comprising:
responsive to a request to present content items to a viewing user of an online system, determining an amount of information to be evaluated by each of a plurality of devices for selecting the content items for presentation to the viewing user based at least in part on latency periods of the plurality of devices and a target latency period, a respective latency period of a respective device corresponding to a respective amount of time spent by the respective device to select one or more content items for presentation to a respective viewing user of the online system; and communicating the determined amount of information to each of the plurality of devices to evaluate for selecting content items for presentation to the viewing user.
