摘要: A scheduling technique for a multicore device is provided. A scheduling apparatus for a multicore device calculates decision values for matrix elements of a decision matrix composed of virtual CPUs assigned to physical CPUs, selects a virtual CPU corresponding to a matrix element having the greatest decision value among the calculated decision values, and changes a currently executed virtual CPU of the physical CPU where the virtual CPU migration event has been generated, into the selected virtual CPU.
