Abstract: A distributed computing system, having a plurality of computers that differ from each other in terms of performance, load, and type, uniformly manages local priority schemes adapted in the respective computers by utilizing the concept of "urgency" or "time limit". Each of the computers includes a priority level conversion procedure for performing a conversion between an urgency level and a priority level of processing in accordance with the performance and the load of the computer, and a priority level changing procedure for changing a priority level of a program, which executes the processing, in accordance with a priority level indicated by the priority level conversion procedure.

Abstract: In a distributed computing system consisting of a plurality of computers each holding the computer reliability of its own, one of the computers includes a reliability management program, This reliability management program manages the program reliability required for each of a plurality of programs to be executed in the system. The reliability management program includes the steps of inquiring the computer reliability of each of the other computers to receive the computer reliability held in each of the other computers thereby preparing a computer information table, searching the table to find the values of the computer reliability of the computers corresponding to those of the program reliability of the individual programs, and allocating, on the basis of the result of the search, the individual programs to the individual computers.

Abstract: A distributed processing system capable of realizing efficient management of a multiplicity of objects in a large scale distributed processing comprises an objectification unit which makes it possible to handle an assembly of objects as one object and a message transfer unit by which a request for a processing to one object provided by objectification by the objectification unit is made to an optimal one of plural objects subjected to objectification.

Abstract: In a graphic data processing system of a CAD system for the design of an LSI, there is provided a display screen, a storage in which graphic data structured in the hierarchy of three levels, i.e. a functional block diagram level, a logical symbol level and a circuit component level, and a pointing device for designating a window within the display screen. The display method of the present invention is characterized in that the size of a designated window is judged and the graphic data of the concept level corresponding to the judged size of the window is read out and displayed within the window.

Abstract: A hand-written character/graphic is recognized in a character recognition mode or a graphic recognition mode designated in accordance with stroke information supplied from a tablet input device which samples the hand-written character/graphic and converts it to the stroke information. The recognition mode is automatically designated by comparing a longer one of projection lengths on x-axis and y-axis of stroke coordinates with a predetermined threshold for a hand-written character input.

Abstract: An apparatus for recognizing and displaying handwritten characters and figures in which input stroke information on a handwritten input character or figure is read out by an electromagnetic tablet, recognition means performs character/figure recognition on the basis of the feature of the input stroke information, display means displays the input stroke information and the result of recognition, and when the result of recognition is displayed on a display screen of the display means, stroke information having been used for recognition is erased from the display screen, and stroke information which is not yet used for recognition, is left on the display screen.
