Abstract

PURPOSE:To prevent a system from missing its proper processing due to a change in processing order during the retrieval of processors by allowing a control device in a processing request storing device to analyze condition information included in processing request information and judge whether the information is storage or transfer. CONSTITUTION:A CPU in each of control devices 8 to 10 detects whether a processing request is sent from one of processing request devices 1 to 5 or transferred from another control device 8, 9, or 10. When the request is sent from one of the devices 1 to 5, it is judged whether the whole information can be processed within an allowable time or not even if the information of the processing request is stored, and when the processing is available, the information is stored. When the processing is impossible, the information is transferred to other control device 8, 9, or 10. When the request is sent from another control device, the information is stored only when the processing can be executed within the allowable time and when allowable transfer frequency or an allowable queuing time is exceeded, and in other cases, the information is transferred to other control devices 8, 9, or 10. Consequently the system can be prevented from missing proper processing due to a change in the processing order during the retrieval of processors 14 to 16.

2. Description of the Related Art In a conventional information processing control system of this kind, a processing requesting device and a processing device are associated in a one-to-one correspondence, and a predetermined processing device processes only information related to a processing request given from a specific processing requesting device. There are known systems for doing this.

However, in the above system, the processing request amount may vary greatly depending on the processing device depending on the time of day, and a processing device that has a processing request that exceeds the processing capacity and a processing device that has sufficient processing capacity. Occurs, which makes it difficult to improve the throughput of the entire system.

On the other hand, there is known an information processing control system that searches for a processing device that can be processed when the processing request device issues a processing request or when the processing device receives a processing request. There is. According to this system, processing requests are evenly distributed to each processing device, and throughput is improved.

[0005]

However, according to the above information processing control system, a processing request is not sent until a processing device in a processable state is searched for. There is a possibility that the processing request may be accepted by the processing device in the retrieved processable state, and in this case, there is a problem that the processing time of the information related to the processing request is significantly lengthened.

The present invention has been made to solve the problems of the conventional information processing control system, and its purpose is to improve the throughput of the system.
Moreover, it is to provide an information processing control system in which the processing order is not changed during the search of the processing device.

[0007]

Therefore, in the present invention, a processing request device for issuing a processing request for information, a processing request storage device for storing information relating to a processing request issued by this processing request device, and this processing A processing device that is provided in a one-to-one relationship with a request storage device and processes information related to a processing request stored in a corresponding processing request storage device; and a processing request device that is provided in a one-to-one correspondence with the processing request storage device. In addition to providing a control device that receives a processing request sent from the device and controls whether to store the information in a corresponding processing request storage device or transfer it to another, the condition information is included in the information related to the processing request. In addition, the control device compares the condition information of the information stored in the corresponding processing request storage device with the condition information of the sent information, and based on the comparison result, whether the processing request storage device stores the information. And configure the information processing control system to perform control of either forward to.

[0008]

According to the above configuration, the condition information is included in the information related to the processing request, and this condition information is sent to the control device that controls the information storage in the processing request storage device, and then the control device determines whether the storage and transfer are performed. Therefore, the throughput is expected to be improved in that the processing order is not changed by the search of the processing device and the data can be transferred to the processing device capable of processing.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an information processing control system according to an embodiment of the present invention. This information processing control system includes processing request devices 1, 2, 3, 4. …, 5 are provided and the communication path
, 17 are connected to the control devices 8, 9 ,.
Controllers 8, 9, ..., 10 are processing request accumulators 11, 12,
, 13, connected to the processing devices 14, 15 ,. Here, the processing requesting devices 1, 2, 3, 4, ..., 5 are, for example, a central processing unit of a computer, a terminal device, a module in an electronic device, or the like. For example, a processor function or a function as a terminal. , Which has a communication function and the like, and sends the information relating to the processing request generated by the internal processing and the like as the information of the format shown in FIG.

That is, the processing condition information is placed at the beginning of the information, the control condition information is placed next, and the processing information to be processed is placed at the end. The transmission source information is placed in either one. The above processing condition information includes
The "priority of processing", "allowable processing waiting time" and the like are included, and the control condition information includes "processing request occurrence time", "allowable transfer count" and the like. These are created on the basis of the programs and data that the processors of the processing requesting devices 1 to 5 own each time a processing request is generated. Figure 2 created in this way
When the information relating to the processing request as shown in (1) is created, the control is transferred to the communication function unit, and the information relating to the processing request is transmitted to any of the control devices 8, 9, ..., 10 via the communication path 17. It Here, which of the control devices 8, 9, ..., 10 is to be sent is freely set by design, but the control device 8, 9 ,. In some cases, the information is sent to another control device.

The control devices 8, 9, ..., 10 store the received information in the corresponding process request storage devices 11, 12, ..., 13 or transfer it to another control device as described later. Then do. The processing request accumulating devices 11, 12, ..., 13 are read / write-free memories, and, for example, the processing devices 14, 15 ,. The devices 14, 15, ..., 16 take out information in the order in which the processing should be performed and perform the processing. Processors 14, 15, ..., 16 are
For example, it is a central processing unit of a computer, a terminal device or each module in an electronic device, and has a processor function and a function as a terminal. Processors 14, 15, ...
The processing result performed by 16 is, for example, terminated by the processing such as printout in the case of a terminal device, and the calculation result is necessary in the case of a central processing unit or the like, for example, in the reverse route to the above, Alternatively, it is returned to the transmission source attached to the information related to the processing request through another route (not shown).

The control devices 8, 9, ..., 10 are composed of, for example, a microcomputer having a communication function, and include C
It has at least a PU, a main memory, and a communication control unit. That is, when the CPUs of the control devices 8, 9, ..., 10 receive the information relating to the processing request from the communication control unit, they activate the program of the flowchart shown in FIG. Processing request storage device 11, 12, ..., 13
, Or transfer to other control devices 8, 9 ,.

In other words, the CPU is whether the information relating to the received processing request is sent from the processing requesting devices 1 to 5 or is transferred from the other control devices 8, 9 ,. Is detected (101). Here, when it is detected that it is sent from the process requesting devices 1 to 5,
From the information related to the processing requests accumulated in the corresponding processing request accumulating devices 11, 12, ..., 13, the processing devices 14 such as the respective priorities, the number of the processing requests, the time required for processing the information related to the processing requests, etc. Detects and calculates the load of 15, 15, ..., 16 (102)
, And compare these with the “priority order” and “allowable processing waiting time” of the processing condition information in the information related to the receipt (103)
Even if the information is accumulated, it is detected whether all the information can be processed within the allowable time and whether the processing conditions can be satisfied (104). Here, when the processing conditions can be satisfied, the processing request accumulating devices 11, 12,
…, Accumulate in 13 (105). On the other hand, when the processing condition cannot be satisfied, “1” is subtracted from the “allowable transfer count” information in the control condition information in the information, and the information is transferred to the other control devices 8, 9 ,. Yes (106).

On the other hand, when it is detected in step 101 that the transmission source is the control device, the control condition information is extracted from the information relating to the received processing request (107), and the "allowable transfer count" information is set to zero. If not, or from the "processing request occurrence time" and the current time (by its own timer),
It is detected whether the "allowable processing wait time" in the processing condition information is exceeded (108). If either, the process proceeds to step 105 and the corresponding processing request accumulating device 14, 1 is processed as described above.
If the information is stored in 5, ..., 16, and the "allowable transfer count" is not zero and the "allowable processing wait time" is not exceeded, the process proceeds to step 102, and the transmission source is the processing requesting device. The same control as in some cases is performed. Thus, the information relating to the processing request is processed by the processing device 1 according to the conditions.
They are transferred in search of 4, 15,…, 16.

In the system of this embodiment, the processing devices 14, 1
5, ..., 16 may be central processing units or terminal units as long as they satisfy the above-mentioned requirements, but in order to send information from the processing requesting units 1 to 5 to any of the control units 8, 9 ,. Therefore, the processing devices 14, 15, ..., 16 must be homogeneous devices. In a system in which heterogeneous devices are mixed, the present invention can be implemented between homogeneous devices.

[0016]

As described above, according to the present invention, the condition information is included in the information related to the processing request, and the condition information is sent to the control device for controlling the information storage in the processing request storage device and then the control device. Since the judgment of accumulation and transfer is made at
It can be prevented that the processing order is changed during the search of the processing device and the processing is not properly performed. In addition, the throughput of the system can be improved because a processing device capable of processing is searched.
