According to one embodiment, an information processing apparatus includes a processor, a non-volatile storage unit, a receiving unit, a judging unit, and a transmitting unit. The receiving unit receives from the processor an inquiry about accessibility of the storage unit. The judging unit judges, upon receipt of the inquiry, whether the storage unit is accessible on the basis of a start-up time period between starting power supply to the storage unit and activation of the storage unit. The transmitting unit transmits a judgment result obtained by the judging unit to the processor.

According to an embodiment, a control device includes a receiving unit, a judging unit, an estimating unit, a deciding unit, a directing unit, and a sending unit. The receiving unit is configured to receive an interrupt request requesting a processing device that includes elements capable of being individually subjected to voltage control to execute an interrupt process. The judging unit is configured to judge a state of the elements. The estimating unit is configured to estimate a start-up time for the element to change into an operating mode after power is supplied. The deciding unit is configured to decide a starting point in time at which power supply is to be started on basis of a difference in the start-up times between the elements. The directing unit is configured to direct a power supply unit for supplying power to the elements. The sending unit is configured to send the interrupt request.

摘要:
In a data transfer scheme using a caching technique and/or a compression technique which is capable of reducing the network load of a network connecting between data transfer devices, correspondences between data and their names are registered at the data transfer devices and the corresponding names are transferred, instead of transferring the data, for those data for which the correspondences are registered, so that it is possible to reduce the amount of transfer data among the data transfer devices.

According to an embodiment, a cache memory device caches data stored in or data to be stored in a memory device. The cache memory device includes a memory area that includes a plurality of cache lines; and a controller. When the number of dirty lines among the cache lines exceeds a predetermined number, the controller writes data of the dirty lines into the memory device, each of the dirty lines containing data that is not written in the memory device.

According to one embodiment, an information processing apparatus includes an auxiliary storage unit, a non-volatile main storage unit, a secondary cell, a first writing unit, and a second writing unit. The non-volatile main storage unit includes a cache area to temporarily store therein data that is to be stored in the auxiliary storage unit. The first writing unit writes the data into the cache area. The second writing unit writes the data written in the cache area into the auxiliary storage unit when an amount of power in the secondary cell is greater than a predetermined first threshold.

Server side data transfer devices and client side data transfer devices can be provided in multiple-to-one, one-to-multiple, or multiple-to-multiple manners.
摘要:
In a data transfer scheme using a caching technique and/or a compression technique which is capable of reducing the network load of a network connecting between data transfer devices, correspondences between data and their names are registered at the data transfer devices and the corresponding names are transferred, instead of transferring the data, for those data for which the correspondences are registered, so that it is possible to reduce the amount of transfer data among the data transfer devices. Even when the name corresponding to the data is not registered so that it is impossible to transfer the corresponding name instead of transferring the data, it is possible to reduce the amount of transfer data among the data transfer devices by transferring the compressed data in which this data is expressed in a compressed form by utilizing the name corresponding to the registered reference data.
