Abstract: An initial etch forms a trench over first contact areas of a plurality of NAND strings, the initial etch also forming individual openings over second contact areas of the plurality of NAND strings. Material is added in the trench to reduce an area of exposed bottom surface of the trench while maintaining the individual openings without substantial reduction of bottom surface area. Subsequent further etching extends the trench and the plurality of individual openings.

Abstract: An information processing device has: a plurality of components supplied with power and performing given operations; a power allocation control part controlling the ratio of power allocated to the plurality of components; and an operation status acquisition part acquiring the operation status of at least one of the plurality of components. The power allocation control part controls the ratio of power allocated to the plurality of components so that a preset condition is satisfied on the basis of the operation status of at least one of the plurality of components.

Abstract: An information processing device includes: a measurement unit 10 for measuring respective use rates of a plurality of coprocessors each for executing a job, respective use rates of a plurality of interface cards each for passing data input or output by each of the plurality of coprocessors, and respective latencies and respective throughputs in communication between the plurality of coprocessors and the plurality of interface cards; and a determination unit 20 for determining a coprocessor that is to execute the job from among the plurality of coprocessors, based on a result of the measurement by the measurement unit 10.

Abstract: A communication device reducing the processing time to install data on a disc storage medium onto multiple servers is provided. A protocol serializer 10 of a communication device 5 serializes read requests received from servers A1 to A2 for target data stored on a disc storage medium K in a processing order. A cache controller 11 determines whether the target data corresponding to the read requests are present in a cache memory 4 in the order of serialized read requests and, if present, receives the target data from the cache memory 4 via a memory controller 12. If not present, the cache controller 11 acquires the target data from the disc storage medium K via a DVD/CD controller 13. Then, the protocol serializer 10 sends the target data acquired by the cache controller 11 to the server of the transmission source of the read request corresponding to the target data.

Abstract: A power distribution system is adapted to a management module connected to a plurality of servers, each of which is varied in power consumption in response to a power mode and performance thereof, via a power allocation request line and a power allocation response line. The management module records the upper-limit power setting, the power allocations, and the power pool with regard to the servers. The server records the power mode, the power allocation, the upper mode request threshold, and the redundant power which is calculated based on the difference between the power allocation and the actual power consumption. The management module recovers the redundant power from the server so as to update the power pool. Upon receiving a power allocation request, the management module distributes at least a part of the power pool to the server, thus allowing the server to shift the power mode to the upper mode.

Abstract: An apparatus which communicates with another apparatus includes a control unit which monitors a power consumption of the apparatus, supplies a power to the another apparatus when the power consumption includes a surplus, and requests the another apparatus to supply the power when the power consumption includes a shortage, and an adjusting unit which adjusts the power consumption of the apparatus according to an operation of the control unit.

Abstract: A data processing system comprises a plurality of key production modules each of which stores keys required to encrypt data and decrypt the encrypted data, produces a new key, encrypts the newly produced key by using one of the keys stored therein as a master key, and stores the encrypted key therein. The data processing system comprises a key replication unit that, upon producing a new key in one of the key production modules serving as a source key production module, urges the source key production module to encrypt the newly produced key by using one of the keys stored in another of the remaining key production modules serving as a destination key production module, and then stores the encrypted key in the destination key production module, thereby executing a key replication process.

Abstract: Provided is a virtual computer system capable of finding a configuration whose total sum of memory access delays is smaller than that of a current configuration. In a virtual computer system in which with memory access times within a node and between nodes differing from each other, a hypervisor controls a plurality of virtual processors which execute a process on a plurality of nodes, the hypervisor includes a unit which obtains a total sum of memory access delay time on the virtual machine based on affinity information indicative of a latency or a band of communication between the virtual processors and traffic between the virtual processors, and a unit which reconfigures physical resources based on the total sum of delay time.
