Abstract: 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.

Abstract: A tag management device executes a process including adding, to data received, sort-free identifiers that indentifies 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.

Abstract: 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.

Abstract: 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.
