Abstract: A network system for an electronic conference in which users interact by transmitting and receiving data by computers connected to a network is provided. The computers include one or more terminal devices, a control device that controls a target, and a server device that receives data and that distributes the received data to a device different from a transmission source of the data. The control device includes a module that executes a control arithmetic operation, and a detection module that detects an event indicating a matter generated in association with the target from an operation state of the target according to control. The network system includes a module that transmits a convocation notice to an electronic conference in order to correspond to the event to one or more users to be involved in correspondence of the event through the network when detecting the event by the detection module.

Abstract: A pipeline computing apparatus (110) comprises: a computing unit (120) configured as a pipeline; a node monitoring unit (161) that obtains a node processing time; a queue monitoring unit (162) that obtains an accumulated message amount; a priority variable calculating unit (163) that, on the basis of the node processing time and the accumulated message amount in a reception queue in a stage previous to the node, calculates a priority variable of the node; and a time allocating unit (164) that allocates operating time to each of nodes in accordance with the priority variable.
