Description

  The present invention performs a simulation for a desired event, for example, as in a real-time type traffic simulation device, and displays a calculation result on a single large multi-screen formed by arranging a plurality of displays. The present invention relates to a computer-type display device.

FIG. 1 shows a diagram for performing a simulation by connecting a display device to a conventional single computer, and FIG. 2 shows a method for performing processing in parallel by connecting a plurality of conventional computers to each other. FIG. 3 shows a diagram of nine conventional displays arranged side by side, and FIG. 4 shows a diagram showing an example of a configuration of five conventional computers. Yes.
For example, in the field of traffic simulation, as shown in FIG. 1, a method of performing a simulation by connecting a display device (display device) 2 to a single information processing device (computer) 1 is common.
However, when performing real-time simulation over a wider area, a single computer lacks both computing power and display capacity.
For this reason, as shown in FIGS. 2 and 3, a plurality of computers 3, 3 are connected to each other to perform processing in parallel, and the display devices 4 connected to the computers 3 are arranged one above the other vertically and horizontally. A method for constructing a screen is proposed in Non-Patent Document 1 below.

FIG. 4 shows an example in which a traffic simulation is performed using five of the multi-display arrangements having the structure of FIG.
As shown in FIG. 2, the nine computers 3 and 3 connected to the LAN 5 are identified by their IP addresses on the LAN.
In the case of the embodiment of FIG. 4, five displays are located at the coordinates (2,1), (1,2), (2,2), (3,2), (2,3) in FIG. Each display is performed by the operation of five computers. Therefore, as is clear from FIG. 4, the road map data of the respective responsible portions must be loaded into the five computers at the above coordinates.
In addition, movement of a car occurs between computers that are adjacent vertically and horizontally. That is, as the car 6 travels in FIG. 4, the vehicle 6 moves from the processing area of the computer 7 to the processing area of the computer 8. At the moment when the vehicle 6 moves, the computer 7 notifies the computer 8 of the movement of the vehicle via the LAN 5 and then moves.
For this reason, each computer must grasp the mutual positional relationship that the computer 8 is arranged on the right side of the computer 7. In general, a certain computer must know whether there are other computers on its top, bottom, left and right, and if so, what its IP address is.
As described above, in the prior art, it is necessary to load road maps data assigned to each computer and load IP addresses (computer IDs) of adjacent computers existing in the upper, lower, left, and right directions. there were.

  The present invention has been made to solve such a problem. Even if the above-mentioned various types of information are not loaded manually into each computer, the information is centrally held on the master computer, and It is possible to automatically load the above-mentioned various information to each computer simply by operation on the computer, and various map data with different shapes can be defined regardless of the physical arrangement of the display (computer). It is intended to be able to be performed on an arbitrary physical arrangement.

The above purpose is the structure (MP structure shown in FIG. 5) showing the physical arrangement of the computer (display). Here, “MP” is an abbreviation for “Multi Processor Multiprocessor”, and in the present application, simply “MP”. The logical configuration definition information (MP configuration shown in FIG. 7) in which the physical arrangement of the computer (display) is defined in the data of the notation) and only the computer used for the simulation is floated from the physical arrangement of the computer. ) Can also be prepared separately, and these can be achieved by temporarily holding them on the master computer.
That is, the multi-computer display device according to the present invention is
A multi-computer type display configured to connect a plurality of computers to each other and perform processing in parallel, and to display the processing results on one screen as a whole by arranging displays connected to each computer vertically and horizontally In the device
One computer selected from the plurality of computers is a master computer, and the master computer includes multiprocessor (MP) structure data including physical arrangement information of all the computers corresponding to the arrangement of the displays, Multiprocessor (MP) configuration data for maintaining the relative positional relationship of a part of computers corresponding to a combination of a part of adjacent displays on which an image is to be displayed during placement, and the remaining from the master computer It is characterized in that the display using the above-mentioned part of the computer is performed by a unified operation on the computers.
Another embodiment of the multi-computer type display device according to the present invention is:
A multi-computer type display configured to connect a plurality of computers to each other and perform processing in parallel, and to display the processing results on one screen as a whole by arranging displays connected to each computer vertically and horizontally In the device

A server for recording the multiprocessor configuration data for maintaining the relationship, and
One computer selected from the plurality of computers is used as a master computer, and the display using the partial computer is performed by a unified operation from the master computer to the remaining computers. It is.

The definition of the MP structure is set when the computer is first installed or when the computer is added, and usually does not need to be changed. On the other hand, various configurations of the MP configuration are conceivable depending on the road map to be simulated.
By introducing such a concept of MP configuration, it is possible to create road maps of various shapes without being conscious of the physical arrangement of computers, and to place them at arbitrary positions on the physical arrangement, and to It can be done simply by operating on the master computer.

The best mode for carrying out the present invention will be described below with reference to the embodiments shown in the drawings.

FIG. 3 is a diagram in which various types of information are centrally arranged on one (master computer) of the computers in FIG. 2.

The MP structure shows the physical arrangement of the computer as shown in FIG. The numerical value is the absolute coordinate of the computer and is expressed by two decimal numbers with “1, 1” in the upper left as a reference. The master computer holds the IP address (computer ID) of the computer at the position of each coordinate. FIG. 5 shows the MP structure data.
The MP configuration is a logical configuration that floats from the physical layout, and various configurations are conceivable depending on the scale of simulation and the shape of the road map.
When defining the MP configuration, it is done by filling the upper left side. For example, when the simulation is performed with the shape as shown in FIG. 6, the MP configuration data is as shown in FIG.
In use, it is possible to translate this MP configuration for use. The amount of movement in the vertical direction is y, and the amount of movement in the horizontal direction is x. In the case of FIG. 8, x = 0 and y = 0, but in the case of FIG. 9, the vertical movement amount y = 1 and the horizontal movement amount x = 0. Thus, once the MP configuration used for the simulation and its position are determined, it is possible to determine which computer is responsible for which part of the simulation by comparing this with the MP structure data in FIG. .

At the start of the simulation, the master computer designates one of a number of MP configurations (configuration number) and the movement amounts x and y and transmits them to each slave computer to prepare for the simulation. By reading the information on the master computer in FIG. 10, it is known whether each slave computer is responsible for this simulation, if so, what part of the region it is responsible for, and which computer is the adjacent processor. Preparation can be done.
With the above configuration, the user does not have to load various simulation data separately on each computer, but only has to input the MP configuration number and the parallel movement amounts x and y on the master computer. Is significantly improved.

In the above embodiment, the MP structure data 9 and the MP configuration data 10 are configured to be held in one master computer selected from among the plurality of computers 3, but these data are provided separately. You may make it hold | maintain in the server which was.
