1. A computer-implemented method comprising: receiving a plurality of computing tasks for execution by a computing system; determining a first configuration setting for a first computing task of a plurality of computing tasks and a second configuration setting for a second computing task of the plurality of computing tasks, wherein the first configuration setting differs from the second configuration setting; booting a first computing node of the computing system according to the first configuration setting; booting a second computing node of the computing system according to the second configurations setting, wherein the first computing node and the second computing node are connected via a network; loading the first computing task into the first computing node for execution; loading the second computing task into the second computing node for execution; after the first computing task finishes on the first computing node, determining whether another computing task associated with the first configuration setting has not been executed; when it is determined that a third computing task associated with the first configuration setting has not been executed, loading the third computing task into the first computing node for execution; when there is no computing task associated with the first configuration setting remaining unexecuted, rebooting the first computing node according to a third configuration setting different from the first configuration setting; and loading a fourth computing task of the plurality of computing tasks associated with the third configuration setting into the first computing node for execution.
