Abstract:
A memory swap management method that can preferentially place in a primary storage device a process that has a high possibility of being executed next, thereby shortening the time to start executing the next process. A planned execution sequence of jobs is stored when there are a plurality of jobs waiting to be executed. A process as a swap-out candidate and a process as a swap-in candidate are determined based on the execution sequence and types of processes stored in the primary storage device. According to the determination, the process as the swap-out candidate is swapped out from the primary storage device to a secondary storage device, and the process as the swap-in candidate is swapped in from the secondary storage device into an area of the primary storage device freed as a result of the swap-out.
