Systems and methods are provided for task scheduling and device management. Such system may comprise (1) a server comprising a client module, a master module, a first node, a second node, and a third node, and (2) one or more worker devices each coupled to the server and one or more computing devices. The worker devices may be configured to obtain device information of the computing devices, register the computing devices under the first node, and indicate statuses of the computing devices to the server. The client module may be configured to obtain task data associated with a task and register the task under the second node. The master module may be configured to assign under the third node the task to one or more of the registered computing devices based at least on the obtained device information, the obtained task data, and the computing device statuses.
