    摘要: An order-relation analyzing apparatus collects assigned destination processor information, a synchronization process order and synchronization information, determines a corresponding element associated with a program among a plurality of elements indicating an ordinal value of the program based on the assigned destination processor information, when an execution of the program is started, and calculates the ordinal value indicated by the corresponding element for each segment based on the synchronization information, when the synchronization process occurs while executing the program. When a first corresponding element associated with a second program, of which the execution starts after the execution of a first program associated with the first corresponding element finishes, is determined, the ordinal value of the second program is calculated by calculating the ordinal value indicated by the first corresponding element.

    摘要: A memory system includes a volatile first storing unit, a nonvolatile second storing unit, and a controller. The controller performs data transfer, stores management information including a storage position of the data stored in the second storing unit into the first storing unit, and performs data management while updating the management information. The second storing unit has a management information storage area for storing management information storage information including management information in a latest state and a storage position of the management information. The storage position information is read by the controller during a startup operation of the memory system and includes a second pointer indicating a storage position of management information in a latest state in the management information storage area and a first pointer indicating a storage position of the second pointer. The first pointer is stored in a fixed area in the second storing unit and the second pointer is stored in an area excluding the fixed area in the second storing unit.

    摘要: A task management apparatus comprises a plurality of processors, and correspondingly stores, a plurality of tasks to be assigned to the processors within a predetermined period of time, and temporal groups each of which is assigned to the plurality of the tasks. The task management apparatus assigns one of the tasks to one of the processors. After having assigned the task, the task management apparatus assigns, to the one of the processors that has finished processing the assigned task, the other tasks that are in correspondence with the same temporal group as the temporal group with which the assigned task is in correspondence, before assigning the tasks that are not in correspondence with the temporal group.
