METHOD FOR OPERATING SEMICONDUCTOR DEVICE AND SEMICONDUCTOR SYSTEM

A method for operating a semiconductor device includes obtaining task structure information of a task processed in a multiprocessor system. The multiprocessor system includes a plurality of nodes, each comprising one or more processing units and a memory directly connected to the processing units. The plurality of nodes include a local node to which an input/output (I/O) device is directly connected and a remote node having no direct connection to the I/O device. The method further includes evaluating the task structure information to determine whether the task is an I/O intensive task and assigning the task to the local node if the task is evaluated to be the I/O intensive task.
