Abstract: Software that implements processing executed through coordination between multiple hubs is efficiently developed. An information processing system comprises a plurality of AP execution devices that are information processing apparatuses provided in each of a plurality of hubs to execute AP software. Each of the AP execution devices stores common AP software that executes the same processing blocks in the same order. The AP software includes transfer processing blocks implementing processing to coordinate processing of the processing blocks executed by a first one of the AP execution devices in a first one of the hubs with a second one of the AP execution devices in a second one of the hubs. Once the processing reaches a first one of the transfer processing blocks during sequential execution of the processing blocks of the AP software, the first AP execution device transmits a coordination start message notifying of start of the coordination, to the second AP execution device. Once the second AP execution device receives the coordination start message, the second AP execution device starts sequential execution from a processing block following the first transfer processing block.

Abstract: A distributed processing system includes a plurality of information processing apparatuses communicably coupled to one another and is capable of performing parallel processing in which the information processing apparatus performs predetermined processing in parallel with the other information processing apparatuses. The distributed processing system including a configuration-information storing part that stores configuration information concerning the number of the information processing apparatuses configuring the distributed processing system and a combination of the information processing apparatuses, a state monitoring part that monitors an operation state of each of the information processing apparatuses, and a system reconfiguring part that, when detecting a change of the operation state of the information processing apparatus, changes the configuration information based on the number and combination of information processing apparatuses in operation and causes, based on the changed configuration information, at least one or more of the information processing apparatuses to perform the predetermined processing.

Abstract: A processing system includes an allotment server to receive and distribute events to a plurality of processing servers and an entry server to set pieces of information to the allotment server used upon the plurality of processing servers executing data processing; the entry server divides the pieces of data into groups based on the data items; allots a message to the groups; and transmits the pieces of information on the types of events, the message, the data items and the processing servers whose pieces of data processing are grouped and stored to the allotment server; upon receiving the events, specifies the message corresponding to the received events based on the data items included in the received events and the stored data items; selects the processing server to which the specified message is to be transferred; and transfers the specified message to the selected processing server.

Abstract: The present invention relates to a distributed processing system having a master node and a plurality of worker nodes. Each worker node has an assigned identifier. A worker node caches in its own memory first output data, which is the result of the execution of a first task, and copies said first output data to another worker node. The master node selects, on the basis of the identifier information of the first worker node, a worker node to which to assign a second task, wherein the first output data is used as input data.
