Abstract: The invention introduces a method for determining processing nodes for executed tasks, performed by a processor when loading and executing a daemon, and containing at least the following steps: obtaining a first evaluation score associated with usages of I/O devices of a first node by a task in a time interval; obtaining a second evaluation score associated with usages of I/O devices of a second node by the task in the time interval, wherein the task is executed by a processor of the first node; and when the second evaluation score is higher than the first evaluation score, switching execution of the task to a processor of the second node.
