A cluster system comprises a plurality of nodes that provides data-access service to a shared storage, each node having at least one failover partner node for taking over services of a node if the node fails. Each node may produce write logs for the shared storage and periodically send write logs at predetermined time intervals to a global device which stores write logs from each node. The global device may detect failure of a node by monitoring time intervals of when write logs are received from each node. Upon detection of a node failure, the global device may provide the write logs of the failed node to one or more partner nodes for performing the write logs on the shared storage. Write logs may be transmitted only between nodes and the global device to reduce data exchanges between nodes and conserving I/O resources of the nodes.

The present invention relates to a method of computing the result of a moving range query and the locations of safe exits in a road network and, more particularly, to a method and apparatus that receive a range query request from a moving client terminal and that provide a range query result, a safe region in which the range query result is maintained, and the locations of safe exits. The present invention provides a method in which a server provides a first query processing result and information about a safe region that provides a range query result identical to the first query result, thereby minimizing communication between a server and a client terminal when the client terminal is located in the safe region.

The invention provides a method for trading products in a matching system in a price guessing manner. The method comprises steps as follows: product information is acquired in real time by a data acquisition module in the matching system which is pre-installed on an intelligent POS (point-of-sale) machine or downloaded onto a personal mobile terminal by a passenger through the Internet, and the passenger trades the products in the matching system according to the product information; the product information comprises the price range of each product, and the passenger inputs one or more passenger bids in the matching system through input equipment according to the price ranges and uploads the one or more passenger bids to a data storage module in the matching system after confirming that the one or more passenger bids are right. The method for trading the products in the matching system in the price guessing manner has the benefits as follows: particularly for upgrading trades at a boarding gate, the seat utilization rate of each plane is increased, the vacancy rate of each plane is decreased, and the marginal income is increased.

The invention discloses an FPGA-based neural network calculator generation method and device. The method comprises the steps of determining a dependency relationship of each network layer in a neuralnetwork; grouping the network layers, wherein the dependency relationship of the network layers in each group are the same; determining the size of an array block required by each group; and deployingand deploying the FPGA according to the dependency relationship of the network layer in each group and the size of the array block required by each group so as to obtain the calculator of the neuralnetwork.
