A non-transitory, computer-readable recording medium having stored therein a processing program causes a computer to execute a process including reconstituting a specific portion of received data, based on reference information specifying a referenced portion of the received data for selecting processing data from the received data, the processing data being subject to a query processing; determining whether to discard the received data, based on the specific portion of the received data and a selecting condition for selecting the processing data; and reconstituting the received data when the determining determines not to discard the received data.

Computer product, processing system, and processing method

An apparatus for processing data includes a processor configured to acquire size information on a size of first result data from a first node. The first result data is generated in first distributed processing executed by the first node on a first part of first input data for the first distributed processing executed by a plurality of nodes. The processor is configured to acquire data arrangement information for second distributed processing executed by the plurality of nodes. The processor is configured to generate a data arrangement instruction on basis of the size information and the data arrangement information. The data arrangement instruction defines an arrangement pattern of second result data generated in the first distributed processing executed by the plurality of nodes and stored in the plurality of nodes as the second input data. The processor is configured to transmit the data arrangement instruction to the plurality of nodes.

Apparatus and method for processing data

A computer acquires a particular entry(ies) from a database that includes plural entries for each of which a key is determined; stores the particular entry(ies) into a memory provided in the computer and used as one of memories that store the database in a distributed manner; and associates a particular piece of communication endpoint information with a network interface of the computer. Each key for each particular entry belongs to a particular subset among mutually disjoint subsets of a domain of keys. The particular piece of the communication endpoint information is one of a predetermined number of pieces of the communication endpoint information and is associated with the particular subset. Each piece of the communication endpoint information logically identifies one communication endpoint, is dynamically associated with one network interface which provides access to one of the memories, and is statically associated with one of the subsets.

Recording medium, distribution controlling method, and information processing device

An information processing apparatus includes a first storage device that stores in a first storage area a first data group that includes a first plurality of data to be processed successively, and stores in a second storage area a second data group that includes a second plurality of data to be processed successively, a second storage device that includes a third storage area that stores a command to access data stored in the first storage area and a fourth storage area that stores a command to access data stored in the second storage area, and a processor configured to store, in a corresponding storage area of the third storage area and the fourth storage area, a received command, select one of the third storage area and the fourth storage area, and process one or more command stored in a selected storage area.

Information processing apparatus, computer-readable recording medium, and information processing method

A tag management device executes a process including adding, to data received, sort-free identifiers that identifies receiving order, and are monotonically increasing or monotonically decreasing numbers or character strings arranged in alphabetical order or a combination thereof; storing, sequentially in a first storing unit associated with a tag that is added to the received data, the identifiers added at the adding; storing, sequentially in a second storing unit in an associated manner, the received data and the identifiers added at the adding; and searching, when a storing unit associated with a tag to be searched for is the first storing unit, data associated with the tag to be searched for by joining, using an inner join or an outer join, information stored in the first storing unit and information stored in the second storing unit.

Tag management device, system and recording medium

A clock determination method executed by a first one of apparatuses included in a system includes receiving a list including first definite clock values of respective apparatuses, the list being circulated among the apparatuses; determining the first clock value of the first apparatus at a point in time based on a smallest of logical clock values regarding corresponding commands on which processing is not completed, the commands being included in commands received by the first apparatus and the logical clock values being obtained at a time of receiving the corresponding commands and being stored, and updating the first clock value, the updated first clock value being included in the list, by using the determined first clock value; specifying, as a second clock value for the system, a smallest of the first clock values included in the updated list; and transmitting the updated list to a second one of the apparatuses.

Method for determining definite clock and node apparatus

A first node apparatus included in a distributed data store acquires first operation information and a first timestamp corresponding to target data. The first operation information specifies a first operation to be executed on the target data. The first timestamp indicates a first receipt time of the first operation information. The first node apparatus determines whether the first receipt time is earlier than some of second receipt times on the basis of second timestamps and the acquired first timestamp. The second timestamp indicates the second receipt time of second operation information. The second operation information specifies a second operation executed on the target data. The first node apparatus re-executes the second operations together with the first operation on the target data in the order of the receipt time when it is determined that the first receipt time is earlier than some of the second receipt times.

Information processing method and information processing apparatus

A power supply control apparatus communicates with a power control apparatus which controls use of electric power of an electronic apparatus. A receiver unit receives a change request to change a power supply-distribution capacity supplied to one electronic apparatus from the power control apparatus controlling use of electric power of the one electronic apparatus. A calculation unit calculates a sum of the power supply-distribution capacity supplied to the one electronic apparatus in response to the received change request and power supply-distribution capacities supplied to the other electronic apparatuses except the one electronic apparatus. A comparison unit compares the maximum power supply-distribution capacity to the sum of the calculated power supply-distribution capacities. A determination unit determines whether or not a change in the power supply-distribution capacity supplied to the one electronic apparatus is allowable based on a result of the comparison.
