Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an information processing system that can efficiently perform desired information processing using a plurality of information processing apparatuses connected via a coupling device.

[Technical background of the invention and its problems]

In order to perform advanced information processing quickly and efficiently,
2. Description of the Related Art A plurality of information processing devices of the same type or different types are connected via a coupling device to construct an information processing system called a computer complex.

The coupling III takes various types, such as a bus type and a ring type, depending on the coupling method, and is used for mutual information transmission between the plurality of information processing devices.

By the way, the above-mentioned information processing device is realized as a general-purpose computer, a computer dedicated to numerical calculation, an information input/output device, and the like. Generally, a unique number in that system is set and connected to the coupling device.

However, in this type of information processing system, the information processing device that is to execute the requested process is identified using a unique number for each information processing device, and the information processing device is It transmits the information necessary to execute the process. For example, when outputting processed data using a line printer, a number identifying the line printer is designated, the processed data is transferred, and the printed output is performed.

However, the conventional system in which an information processing apparatus is identified using a number and a desired process is executed on that information processing apparatus has a problem in that it lacks flexibility in executing the process.

That is, if the information processing device specified by the number is out of order, it is obvious that the information processing device cannot be operated. Therefore, it is necessary to have another information processing device with the same processing capabilities perform the processing on behalf of the user. However, in order to do so, it is necessary to modify, for example, the program portion for identifying the information processing device.

Furthermore, when an information processing device with more advanced processing functions is added to the system and used, it is necessary to similarly modify the number that identifies the information processing device.

Furthermore, when a plurality of information processing apparatuses with different information processing capabilities are used, it is often the case that the information processing apparatus with the higher information processing capacity is generally designated to execute a desired process. In such a case, processing requests may be concentrated only on a specific information processing apparatus, and the other information processing apparatus may hardly be used. In order to avoid such a situation, it is sufficient to select an information processing apparatus according to its processing status (operation status).

However, as described above, since the information processing apparatus is fixedly identified by the number incorporated in the processing program, there is a problem in that it is very difficult to change or modify the information processing apparatus.

The above-mentioned problems also occur when a system is expanded; for example, even if an information processing device with high information processing capacity is added, it would be impossible to use that information processing device unless the system knew about it. .

Furthermore, in order to utilize the eight additional information processing devices, it is necessary to change the processing program so that the information processing device can be specified. This requires significant modification of the processing program.

In this way, in conventional systems, the information processing VA locations to be executed are fixedly specified by numbers, which lacks flexibility and makes it extremely difficult for the system to fully and efficiently utilize its capabilities. There was a problem.

[Purpose of the invention]

The present invention has been made in consideration of these circumstances, and its purpose is to effectively identify an information processing device that can efficiently execute desired information processing according to the operating status of the system. The object of the present invention is to provide a highly flexible information processing system that can improve processing efficiency.

[Summary of the invention]

The present invention provides a plurality of information processing apparatuses that are interconnected via a coupling device, (1) a means for respectively transmitting information of a process requested to be executed to all the information processing apparatuses, and (2) a means for transmitting information on a given process. From the request information and its own information processing function and its operating state, each piece of information is added to, for example, the addition information of the waiting time T1 for executing the requested process and the processing time T2 required for executing the process. means for generating numerical data for the requested processing consisting of information to which priority information K assigned to the processing apparatuses is added; For example, the information processing apparatus that has generated the smallest numerical data is specified as the information processing apparatus that can most quickly process the requested process.

〔Effect of the invention〕

Thus, according to the present invention, even if the system is expanded or modified, the information processing device most suitable for executing the requested process can be identified by comparing the numerical data generated by each information processing device. , it becomes possible to operate the system efficiently without modifying the processing program.

Therefore, it is possible to make full use of the functions of the system, and it has great practical effects, such as increasing its expandability and making it possible to sufficiently increase the flexibility of system use. It will be done.

[Example of R Ming]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of an embodiment system, in which 1 is a coupling device, and 2a, 2b, to 2n are a plurality of information processing devices mutually connected via the coupling device 1. In FIG.

These information processing units 2a, 2b, to 2n are comprised of, for example, a general-purpose computer, a computer dedicated to numerical calculation, information input/output equipment, and the like.

In addition to the information processing device main body 11, each information processing device a2 has the processing capacity (9J1 physical capacity) of the information processing device main body 11.
a table 12 storing information, a request output unit 13 that outputs information about a process that is requested to be executed, and a request output unit 13 that estimates the time during which the process can be executed in response to a process execution request, and provides a process corresponding to this estimated time. It is configured to include a processing time estimator 14 that generates numerical data.

Further, the coupling device 1 is wired and coupled with a bus 16 that connects the information processing devices 2 to each other, and is connected to the processing time estimating section 14, which is provided corresponding to each of the information processing devices 8 and 2. It is configured to include a selection circuit 17 for transmitting and receiving signals.

When the request output unit 13 issues an execution request for the processing performed by the processing device main body 11, it outputs processing request information of the type shown in FIG.
It is given to all information processing devices 2 via.

This process request information includes a process number a indicating the content of the process.
, unit information b indicating the amount of processing, and parameter C consisting of various data necessary to execute the processing.

That is, as shown in FIG. 3, for example, the table 12 stores information on process numbers a that specify various types of processing contents, and unit processing time d required to execute the processes. The processing number a that specifies the processing content is commonly determined throughout the system, and the unit processing time d is determined according to the processing capacity of each information processing device 2 (processing device main body 11). .

Specifically, for matrix operations, the processing number [1
] is set, and one unit of 71 helix operation is (100
X100 ), and data [10] is set as the unit processing time for executing this. Therefore, in this case, it is shown that this information processing device 2 has the ability to execute one unit of matrix operation in a time of [10].

Similarly, it is shown that the sort 'LJJJ calculation designated by number [2] requires a time of [50] to process one unit. Furthermore, since the line printer output indicated by number [5] does not have that function, the unit processing time is indicated by [oo].

The above-mentioned request output unit 13 outputs, for example, (200x200
), if there is a request to perform a matrix operation,
As the processing request information of the type shown in FIG. 2, the processing number a is set to [1], and the processing mb is set to [23=88 units]. Then, (200x200) worth of data is entered as parameter C indicating information necessary for the processing.

Such processing request information is given to all the information processing apparatuses 2 including the information processing apparatus 2 through the coupling apparatus 1.

The processing time estimating unit 14 of each information processing unit 5A is provided with a buffer that sequentially stores the given processing request information. Since this buffer is configured, for example, as shown in FIG. 11 is calculated as the processing time e.

Specifically, in the above example, 8 units of matrix calculation are requested, and since the processing capacity (unit processing time) of the processing device main body 11 for matrix calculation is given as [10] from table 12, the processing time is e is calculated as [10 x [8] - ['80]. The processing time e obtained in this way and its parameter C are stored in the buffer in the order in which the processing requests are input.

On the other hand, the processing time estimation unit 14 holds in a register the waiting time until the processing device main body 11 can start executing the requested processing. Each time a requested process is specified to be executed by the processing device main body 11, the processing time e required to execute the process is added to the value of the register, and this value is sequentially added as the process is executed. It will decrease.

Therefore, when the value of the register is [0], it means that the process can be executed immediately.

In this way, the processing time estimation unit generates numerical data by adding the above-mentioned processing time information to the waiting time information indicated by the value of the register, and further adding data specific to the information processing device, which will be described later. is output to the coupling device 1.

In this way, the numerical data generated for each processing requested to be performed by each information processing device 2 is different because the information processing capacity (ability) of each information processing device 2 is different, and the operating state thereof is also different. Of course, it will be different. In rare cases, the above @ quantity information may be equal, but in this case, the numerical data is differentiated by the number unique to the information processing device added to the time data.

The selection circuit 17 that receives numerical data from each information processing device a2 sequentially outputs data from the MSB side and performs wired AND processing. If the wired-and-processed data (WA) differs from the data output by itself, it assumes that there is an information processing device more suitable than itself to execute the process, and stops outputting the numerical data. There is. Through this process, the information processing device 2 that has generated the smallest numerical data is selected and specified as the information processing device that executes the requested process.

This selection process will be explained in more detail as shown in FIG.

That is, numerical data (time information, unique number) consisting of time information and a unique number of the information processing device (time information, unique number) ■ (10011001,0000) ■ (01001011,0001) ■ (01011011,0010) ■ (01001100,0100) is generated. Assume that there are four information processing devices A, B, C, and D. In this case, since the data (WA) found at time to is [0], subsequent output of numerical data from information processing device A is stopped. As a result, information processing apparatus A is determined to be unsuitable for executing the process.

Thereafter, at time t2, the data of the information processing device C differs from the wired-and data (WA').

As a result, information processing device C is removed from the selection candidates. Similarly, at time t4, the information processing device is removed from the selection candidates.

In this way, the information processing device B that remained until the end was the one that generated the smallest numerical data among the information processing devices fiA, B, C, and D, and here, the information processing device B was the one that generated the smallest numerical data among the information processing devices fiA, B, C, and D. It can be seen that the device is capable of processing. In this way, the eight information processing devices that have generated the smallest numerical data are selected and specified as the devices that will execute the requested process.

Even if the time information is the same, the device-specific number added as the lower bit of the time information
Only one of them is selected.

In this system, as described above, the information processing apparatus that executes the requested process is selected according to the processing function, processing capacity, and operating state of each information processing apparatus. When the selection processing for one processing request is completed, the selection processing of the information processing device for the next processing request is similarly performed.

Therefore, according to this system, the information process that can process the process the fastest is always specified. Therefore, processing requests are not concentrated on a specific information processing device, and the system can fully utilize its advanced processing functions to efficiently process information.

In addition, in this system, the information processing device is not fixedly identified for the process that is requested to be executed, so if, for example, an information processing device is malfunctioning, another information processing device can be used to correct the problem. Processing can be performed alternatively. Furthermore, if an information processing device with high processing capacity is added due to system expansion, the information processing device can be used effectively even if the user does not know that the information processing device has been added. Furthermore, there is the advantage that there is no need to modify the processing program or change the designation of the information processing device as in conventional systems.

Therefore, great practical effects can be achieved, such as making it possible to realize a highly expandable and highly flexible information processing system.

Note that the present invention is not limited to the embodiments described above. For example, as shown in FIG. 6, a plurality of information processing devices 2a
, 2b, to 2n may be connected in a loop via the coupling device 1. In this case, as shown in FIG. 7, the coupling device 1 receives information with an SP number indicating the information processing device that generated the processing request and an OP number indicating the information processing device that generated the smallest numerical data. The data may be transmitted sequentially via the Then, each information processing device compares the sent numerical data with the numerical data generated by itself, and if its own numerical data is smaller, it uses the smaller numerical data and the device number indicating itself. DP number. On the other hand, if the own numerical data is larger, the sent data is sent out as is.

In this way, when the processing request information goes around and returns to the information processing device that issued the execution request, it becomes possible to specify which processing device should execute the processing. Therefore, the same effects as in the previous embodiment can be achieved.

Furthermore, here, the smallest value of numerical data is selected as time information, but processing cost information may be reflected in the numerical data. In this way, it becomes possible to efficiently perform information processing at low cost.

Further, when storing information in a memory, for example, numerical data corresponding to the effective memory capacity at that time may be generated, and the largest numerical data may be selected. In this case, for example, after inverting each bit of the numerical data, wired AND processing may be performed in the same manner as in the example described above.

In addition, the present invention can be modified and applied to various information processing systems without departing from the gist thereof.
