<p>The present invention relates to a computation scheduling method and a system thereof. The computation scheduling method and the system using the method can determine the operation attributes of an application on a real-time basis to enable all nodes in the system to interactively and organically replace schedulers to satisfy the QoS expected in the system. The scheduling method according to the present invention includes the steps of: detecting an event requesting a scheduler to be replaced; selecting a scheduler corresponding to the event among schedulers; and replacing the scheduler of the node with the selected scheduler without rebooting the node scheduling the usage of a control unit.</p>
