  • Patent number: 10514850
    Abstract: According to an embodiment, an information processing system includes a server and a client. The server includes a storage, a receiver, and a storage controller. The storage is configured to store data and its version in a record indexed by a key for identifying the record. The receiver is configured to receive, from the client, a write request including write data, requested key for identifying a record where the write data is to be stored, and a write version that indicates a version of the write data. The storage controller is configured to replace the data and its version in the record identified by the requested key with the requested write data and the requested write version, respectively, if the version in the record identified by the requested key is smaller than the write version.

  • Patent number: 10489239
    Abstract: According to an embodiment, a multiplexing system includes servers. Each server includes a memory, a processing unit, a decision controller, and a restoring unit. The memory is configured to store internal data. The processing unit is configured to output, as first data, deterministic data or the nondeterministic data. The deterministic data is uniquely determined by an operation based on input data and the internal data having not yet been processed. When the processing unit cannot determine deterministic output it outputs the nondeterministic data. The decision controller is configured to select either the first data output from the each server or the first data output from another server, and decide the selected first data as second data. The restoring unit is configured to, when the second output data is the nondeterministic data, restore the internal data to a state of the internal data having not yet been processed.

  • Patent number: 10162719
    Abstract: According to an embodiment, an ordering device determines a processing order of pieces of data in each computer in a multiplex system. The device includes a preliminary elector and a confidence elector. The preliminary elector is configured to generate, when a vote having the current order number, the current round number, and a nominated state is acquired from a primary computer, a vote that includes data included in the acquired vote, the current order number, a round number following the current round number, and a winning-assured state. The confidence elector is configured to determine, when a vote having the current order number, the current round number, and the winning-assured state is acquired for identical data from each of a threshold or more of the computers, data included in the acquired vote to be data to be processed at the current order number.

  • Patent number: 10165086
    Abstract: According to an embodiment, an information processing system includes a client apparatus and three or more server apparatuses that each store data. The server apparatus includes a first storage, a receiver, a generator, a selector, a transmitter, and a changer. When the number of requests indicating identical changes among the requests of the data candidates is larger than a first threshold, the selector selects one of the requests indicating identical changes, and sets the state of the selected request to a second state. The transmitter transmits the data candidate including the selected request to one or more server apparatuses. When the number of requests in the second state among the requests of the data candidates is larger than a second threshold, the changer updates the history data and changes the data by using one of the data candidates including the requests in the second state.
