The information processing software 2b introduced from the data processing / dividing means 7 is executed.

The display software 4 composed of a program for displaying the data processed in a in a desired display format is inputted in an arbitrary order to the computer device equipped with the information processing software creating means 1. Information processing software creation means 1

FIG. 2 is a flow chart showing the operation of the data processing division means of the information processing system according to the first embodiment, and the processing software division operation will be described with reference to this figure. First, the data processing / dividing unit 7 acquires the information processing software 2a from the information processing software creating unit 1 and stores it in a storage device (not shown) before introducing it into the terminal device 5. After that, the data processing / dividing unit 7 reads the information processing software 2a from the storage device as appropriate, and the processing software 3 included in the software 2a.
Analyze the program structure of a. As a result, the data processing division means 7 recognizes the arithmetic expression set according to the purpose of use of the processing software 3a as a tree structure in which the input data and constants are leaves and the operator is an internal node,
An expression tree whose constituent elements are subtrees consisting of input data, constants and operators required for the above calculation is constructed (step ST
1, arithmetic structure analysis step).

FIG. 3 is a diagram showing an example of an arithmetic expression set in the processing software. The arithmetic expression shown in the figure has data 1, 2, 3 as data to be input from the server device 6 and 2,100 as constants, and is composed of operators +, ÷ and ×. The arithmetic expression as shown in FIG.
Is recognized as an expression tree as shown in FIG. Figure 4
4 is a diagram showing an expression tree of the arithmetic expression of FIG. 3, and the arithmetic expression of FIG. 3 is a tree structure in which data 1, 2, 3 and constants 2,100 are leaves, and operators +, ÷, and × are internal nodes. Becomes More specifically, this expression tree is a subtree composed of data 1 and data 2 and operator +, a subtree composed of constant 2 and operator ÷,
Subtree consisting of data 3 and operator ÷, and constant 100
It consists of a subtree consisting of and the operator x. Further, the above arithmetic expression starts from a subtree consisting of the data 1 or 2 and the operator +, and the processing flows to the subtree consisting of the constant 100 and the operator x. That is, for example, the data obtained by performing the process related to the subtree composed of the data 1, the data 2, and the operator + is the node of the next subtree connected to the operator + which is the node of this subtree. It can be thought of as flowing into the operator ÷.

Here, the fact that the data processing division means 7 constructs the expression tree relating to the arithmetic expression in the processing software 3a means that the program relating to each subtree (the program that realizes the computation relating to each operator). This is equivalent to recognizing each as one subroutine and specifying their mutual relationship. Specifically, for example, information such as a program configuration related to each operator is set in advance in software that realizes the data processing division means 7, and the program related to each operator is automatically generated from the input processing software 3a. Extract and recognize each as a subroutine. After that, for example, arbitrary data is experimentally input to the processing software 3a, the flow of processing between the subroutines is detected, and the processing order is specified. Based on this processing order, the data processing division means 7 identifies the connection order of each subtree and constructs the expression tree related to the arithmetic expression of the processing software 3a. Further, information such as a programming language that describes the processing software 3a for analysis by the software that realizes the data processing and dividing means 7 is the data processing and dividing means 7.
The user may set it appropriately before the processing by.

Next, the data processing / dividing means 7 performs a process related to a subtree having an expression tree related to the arithmetic expression of the processing software 3a, and a subtree related to the next process connected to this subtree. The amount of data flowing to a node (hereinafter referred to as a parent node) (that is, the amount of data required to execute the program corresponding to each subtree) is calculated (step ST2). Specifically, for example, the software that implements the data processing / dividing unit 7 extracts the input data and constants required when executing the program corresponding to each subtree included in the processing software 3a, and extracts the data in each process. Calculate the amount.

When the amount of data required to execute the program corresponding to each subtree is calculated, the data processing division means 7 divides the program corresponding to the subtree of the expression tree related to the operation of the processing software 3a. Then, the processing software 3b, 3c is created. First, the data processing division means 7
Information regarding the processing capacity of the computer device in which the processing software is to be installed is set in the computer device equipped with the software for realizing the above. Here, the information regarding the processing capacity may be information indicating the specifications of the hardware related to the processing of the computer apparatus or the relative magnitudes of the processing capacity between the respective computer apparatuses to which the processing software should be introduced. As a result, in the example of FIG. 1, the computer device equipped with the software that realizes the data processing / dividing means 7 has a higher processing capability in the server device 6 between the terminal device 5 and the server device 6 to which the processing software is to be introduced. Is determined to have.

After that, the data processing / dividing means 7 executes the processing software 3a that minimizes the data amount required for the processing related to the processing software 3c installed in the terminal device 5 having a lower processing capacity than the server device 6. The division position is calculated (step ST3, division step). FIG. 5 is an explanatory diagram for schematically explaining the division processing of the processing software. In FIG. 5, the symbol “□” added to the tree after the data is divided by the data dividing unit 7 is an identification rule registered in place of the root node of the subtree to be cut out. Here, the data processing / dividing unit 7 requires one of the processes based on the amount of data required to process the program corresponding to each subtree (including the amount of data to be transmitted from the server device 6 to the terminal device 5). The division position that minimizes the amount of data is calculated.

In the example of FIG. 5, the data processing / dividing means 7 divides data at the operator ÷ which is the parent node of the data 3 to minimize the amount of data required for one processing of the processed software after the division. The determination is made and the program corresponding to the subtree that uses the data 1, 2, and 3 to be provided by the server device 6 as input data is divided. As a result, the processing software 3b including the program corresponding to the subtree that uses the data 1, 2, and 3 to be provided by the server device 6 as input data, and the expression tree program obtained by cutting out the program of the subtree are included. Processing software 3c is created. after this,
If the processing software 3b is introduced into the server device 6, data 1, 2, 3 is not transmitted from the server device 6 to the terminal device 5, and the use efficiency of the communication network can be improved. Further, by introducing the processing software 3c including a subtree consisting of the constant 100 and the operator x into the terminal device 5, the server device 6 executes the processing software 3b as the processing performed by the terminal device 5 having low processing capability. Only the constant 100 is multiplied to the processing result obtained in this way.

Further, in the above-mentioned division processing, the data processing division means 7 has the data 1 to be provided by the server device 6.
A program corresponding to a subtree containing 2, 3 and a constant 10
An identification rule 8 for identifying a program corresponding to a subtree consisting of 0 and an operator x is registered, for example, in place of the root node at these connection destinations (step ST4, identification rule setting step). Here, the registration of the identification rule 8 means
This corresponds to the addition of a predetermined program (including communication address information of the computer at the installation destination) that specifies the program corresponding to the subtree to be divided. According to this identification rule 8, the processing software 3b newly created by the division and the processing software 3c remaining by the division
The relationship in the expression tree with is identified, and the true processing result can be derived by combining the processing results of the terminal device 5 and the server device 6 described later. That is, the calculation executed by the terminal device 5 in which the processing software 3c is installed and the server device 6 in which the processing software 3b is installed has a relation equivalent to the operation by the processing software 3a.

FIG. 6 is a flow chart showing the operation after the division of the processing software of the information processing system according to the first embodiment. The operation such as the introduction of the processing software after the division and the derivation of the processing result will be described with reference to FIG. explain. When the processing software 3a is divided into the processing softwares 3b and 3c, the data processing dividing means 7 causes the processing software 3 to be divided.
c is combined with the display software 4 and the identification rule 8 to create the information processing software 2b. After that, the computer device equipped with the software that realizes the data processing / dividing means 7 introduces the information processing software 2b and the processing software 3b into the terminal device 5 and the server device 6, respectively, via the communication network. The information processing software 2b is stored in a recording device (not shown) included in the terminal device 5, and is executed by a processing unit including a CPU in the terminal device 5. Similarly, the processing software 3b is also stored in a recording device (not shown) included in the server device 6 and executed by a processing unit including a CPU in the server device 6 (step ST1A, introduction step, process execution step).

First, in the terminal device 5, in order to execute the processing software 3c of the information processing software 2b, the processing result by the arithmetic expression of the processing software 3b associated by the identification rule 8 is required.
Information requesting the provision of the above-mentioned processing result is transmitted to the server device 6 in which b is introduced.

Upon receiving the above request, the server device 6 executes the processing software 3b by using the data 1, 2, and 3 which should be provided to the terminal device 5 by itself, holds the processing result, and identifies the rule. 8 is sent to the terminal device 5 together with information indicating that the data is data (step ST
2A, step ST3A).

The terminal device 5 executes the processing software 3c based on the data related to the processing result of the processing software 3b received from the server device 6 and the identification rule 8, and displays the processing result to be obtained by the original processing software 3a. Derivation (process result derivation step). The processing result obtained as described above is processed as input data of the display software 4 and displayed on a display device (not shown) of the terminal device 5 in a predetermined display format.

When the amount of data required for each subtree is calculated, the data processing / dividing unit 7 performs processing that minimizes the amount of data required to process the processing software to be introduced into the portable information terminal, which is the terminal device 5. The division position of the software 3a is calculated (division step). Here, the data processing dividing means 7 divides a program relating to an arithmetic expression for obtaining the sum of pumping amounts of m pumps into processing software 3b, and further, from the processing software after the division, from the n machine stations.

After that, the data processing division means 7 weights the nodes of the expression tree relating to the calculation of the processing software 3a according to the calculated calculation load at each node.

When the weighting of the nodes is completed, the data processing / dividing means 7 determines in the server device that the calculation load corresponding to the sum of the weights of all the nodes included in the calculation expression tree of the processing software 3b is calculated as described above. A division position having a size corresponding to the processing capacity of 6 is calculated (step ST4c).

After that, the data processing division means 7 divides the program corresponding to the expression tree related to the calculation of the processing software 3a at the above-mentioned division position, sets the identification rule 8 and sets the processing software 3b, 3c. Create (step ST5c, dividing step). Subsequent processing is the same as that described in the first embodiment, so redundant description will be omitted.

As described above, according to the fourth embodiment, the calculation load corresponding to the sum of the weights of the sub-trees depends on the processing capacity obtained in consideration of the fluctuation in processing capacity due to the current load of the server device 6. Processing software 3
Since “a” is divided, the sum of the weights of the operations executed by the server device 6 becomes a size according to the processing capacity of the server device 6 and the dynamic load of the server device 6. The calculation load can be maintained below a predetermined reference value.
