摘要:
A management table is provided in each processor so as to manage the quality of data which is transferred via a common transmission medium which is connected to the processors, and when each processor sends data, it refers to the management table and sends the data to the common transmission medium by adding the attribute information indicating the quality of the data to it, and when each processor receives data, it refers to the management table and decides whether or not to let the program module receive the data on the basis of the attribute information added to the data, so that the flow of information in a distributed system can be managed autonomously for each attribute thereof, and information of an attribute is prevented from flowing into a specific group, and a plurality of attribute informations are integrated to one, and the protection of attributes among different kinds of applications and the connection processing are available.
摘要:
A data transmission method is provided for a multi-computer system which has a plurality of computers mutually connected via a transmission line. The plurality of computers are divided into groups, with an address assigned to each group. Transmission data of a sending computer is provided with a location where the address is assigned and a location where a content code indicating the data content is assigned. The sending computer transmits the data with either the address or content code assigned, and the computers other than the sending computer decide whether or not to receive the data according to either the address or the content code.
摘要:
A method for organizing and programming distributed computer systems in which processors are connected via interconnection or communication networks, such that even if many cases of hardware and software faults occur within the processors or within the networks, such faults do not lead to the failures in the application's computation. Parallel and asynchronous execution of multiple versions of a program module is performed with processors which are connected by a network without involving any direct interaction between the processors during the execution of the same or different versions of the program module. The process includes a step for executing, for each of the distributed program modules, the primary version and its backup version concurrently by use of multiple processors, a step for checking, in each processor, the logical acceptability of the output data produced from its execution of a program module version, a step for sending, in each processor, the acceptable output data to the transmission paths, a step for receiving, in each processor, the message from the transmission paths, checking the logical acceptability of each received message, and detecting the messages belonging to the same program module, and a step for selecting, in each processor, a message based on a selection logic.
摘要:
A distributed processing method and system including a plurality of processors connected via a transmission path, in which a function is provided to an arbitrary processor to receive information and data passing through the transmission path and to obtain the received data based on information indicating input/output relationships between modules corresponding to the association of processing between the modules. When required, necessary portions of the obtained information and logging results are extracted, so that not only the time series data log but also the information or data log can be collected corresponding to the flow of a sequence of processing by establishing a display or print-out module. Furthermore, when data is received from an external device, the system generates a message having information indicating the order of the data and the content code representing content of the data and sends the message to the transmission path. A processor receives messages from the transmission path, and stores the data in accordance with each content code in an order which facilitates trouble shooting of the system.
摘要:
In a processing method for a distributed processing system have a plurality of processors connected through a network for transferring programs among the processors, each processor introduces a program which circulates in the network, assesses the state of the processor for storing the program in that processor, and judges on the basis of the assessment information whether the introduced program is to be executed in that processor.
摘要:
Programs in a plurality of processors connected through a common network are started when a plurality of data necessary for starting the program are received from the network. When the processor receives data from an external equipment, it adds the event number to the data and sends it to the network, and each processor determines whether all data necessary for starting the program in itself have been received and checks the relation among the received data by comparison with the event numbers of the received data.
摘要:
An interactive intelligent interface in a system which performs an interactive processing making the system recognize the capacity of a user of the system. The system has a function of providing a processing method conformable to the recognized capacity of the system user, whereby a processing method to be performed by the system is changed in accordance with the operating or processing capacity of the system user so that a procedure desired by the system user can be performed irrespective of the operating or processing capacity of the system user.
摘要:
The present invention consists in that, when a program constitution in each of processors connected to a common transmission line has changed, a message to this effect is broadcast to the common transmission line, and that, when the message has been received from the common transmission line, information on programs stored in the own processor is broadcast to the common transmission line, whereby the messages indicating the program constitutions in the individual processors are automatically broadcast onto the transmission line at the changes of the constitutions of programs. Besides, in a system wherein a series of processes are executed by a plurality of programs, the relation among programs according to the flow of the series of processes can be recognized using information on the input/output data of each of the programs.
摘要:
A system for loading a program in a distributed system including a plurality of information processing units interconnected by a transmission system comprises an information processing unit for preparing a program and sending the program to the transmission system, another information processing unit having means for receiving the program from the transmission system and storing the program in a memory in accordance with a content of the program, and means for retrieving a program based on program structural information, which program corresponds to the program structural information, and sending the retrieved program to the transmission system, and other information processing units each having means for sending the program structural information to the transmission system and means for selecting a corresponding program from the transmission system and loading the selected program in the unit.
摘要:
In a system which includes of subsystems, and a transmission medium for coupling them, and in which a token is sent to the transmission medium, whereby the transmission medium is occupied; a transmission control method characterized, at least, in that each of the certain subsystems appends a code indicative of a function of certain data to the token and sends the resulting data to the medium, and that the subsystem receiving the data refers to the code indicative of the function of the data, thereby to independently judge whether or not the data is to be accepted into the own subsystem.
