- the application node 1 waits for reception of a processing request from the client 3 (step C1 in FIG. 22).
- the application node 1 transmits a processing request to the storage node 2 (step C1). C3).
- step C3 the storage node 2 to which the processing request is transmitted is stored in the storage node identifier column 1422 in the row where the value of the data identifier column 1421 of the data information storage unit 142 matches the data identifier included in the processing request. It is assumed that the storage node 2 corresponds to the storage node identifier.
- the process request to be transmitted includes the program name and data identifier specified in the process request received from the client 3.
- step C4 when a reply from the storage node 2 is received (step C4), the application node 1 determines whether the reply content is data or a processing result (step C5).
- the application node 1 executes the corresponding program in the process execution unit 12 with the received data as input (step C6), and the data amount of the process result is returned to the storage in which the data is returned. Transmit to node 2 (step C7).
- the application node 1 transmits the processing result to the client 3 that is the transmission source of the processing request (step C8). Thereafter, the application node 1 returns to step C1 and transitions to a processing request waiting state from the client.
- step C5 when the reply content is the processing result, the application node 1 transmits the processing result to the client 3 that is the transmission source of the processing request (step C8). Thereafter, the application node 1 returns to step C1 and transitions to a processing request waiting state from the client.
- the storage node 2 waits for a processing request from the application node 1 (step D1 in FIG. 23).
- the storage node 2 receives a processing request from the application node 1 (step D2)
- the storage node 2 starts processing from the program name column 2441 of the data amount ratio storage unit 244.
- a line that matches the program name included in the request is searched to check whether the value of the data amount ratio stored in the data amount ratio column 2442 of the corresponding line is greater than 1 or less than 1 (step D3).
- step D3 When the data amount ratio is larger than 1 in step D3, the storage node 2 reads data corresponding to the data identifier included in the data request from the data storage unit 245, and displays information indicating that the data and data are processing requests. Is sent to the application server 1 that is the transmission source (step D4), and waits for the reception of the post-processing data amount from the application server 1.

- the data amount column 2432 stores the data amount of the data transmitted to the application server 1 in step D4, and the processed data amount column 2433 stores the processed data amount received from the application server 1 in step D5 (step D6).
- the data amount ratio calculation unit 23 calculates a value obtained by dividing the post-processing data amount by the pre-processing data amount for all rows in which the program name column 2431 of the data amount storage unit 243 has the corresponding program name, and averages them. The value is defined as a data amount ratio (step D7).
- the storage node 2 updates the data amount ratio column 2442 of the row in which the program name is stored in the program name column 2441 of the data amount ratio storage unit 244 with the calculated data amount ratio value (step D8). Thereafter, the storage node 2 returns to step D1 and transitions to a process request waiting state from the application node 1.

- the data amount of the input data is stored in the post-processing data amount column 1433, and the data amount of the processing result data in step D9 is stored (step D11).
- the storage node 2 performs the processing subsequent to step D7 as in the case where the data amount ratio is larger than 1.
- step D6 or step D11 if a new row cannot be secured because the storage capacity of the data amount storage unit 243 is small, the number of rows in the table of the data amount storage unit 243 is counted for each program name, which is the largest. Delete the oldest line of the program name line to make the storage area for the new line. Alternatively, a predetermined number of lines may be secured for each program, and the old data lines may be deleted sequentially.
- the amount of data exchanged between the application node 1 and the storage node 2 can be reduced as in the first embodiment.
- the reason is that, as in the first embodiment, the history of the data amount before and after the processing is recorded for each program, the ratio of the data amount before and after the processing is calculated, and the processing is performed according to the ratio of the data amount. This is because it is configured to determine whether to perform the operation at the node or the storage node.

- FIG. 26 is a diagram showing the structure of the data amount ratio storage unit 144 of the present embodiment.
- the difference from the data amount ratio storage unit 144 of the first embodiment shown in FIG. 6 is that it has a threshold value column 1443.
- the threshold value is a reference value for determining whether the process execution is performed by the application node 1 or the storage node 2 as compared with the data amount ratio.
- the threshold value is a numerical value of 0 or more, and the larger the value, the easier the process execution is performed in the storage node 2.
- the threshold value is not limited to a numerical value, and an identification symbol that forcibly executes the process at the application node 1 or forcibly executes the process at the storage node 2 may be set. A specific node selection method using the threshold will be described later.
- the console 4 issues a threshold setting request to the application node 1 in accordance with the operation of the operator (operator).
- the program name and threshold value are included in the threshold setting request.
- the operator (operator) does not necessarily have to specify the threshold value numerically. For example, it may be specified by a GUI (Graphical User Interface) track bar or pull-down menu, converted into a numerical value in the console 4 and handled as a threshold value.
- GUI Graphic User Interface
- step A3 in FIG. 7 representing the operation of the first embodiment
- step A3 of FIG. 7 it is determined whether the data amount ratio is greater than 1 or less than 1. However, in this embodiment, if a value is set in the threshold value column 1443 of the corresponding program, it is set. Threshold is used as a decision criterion. That is, when the data amount ratio is larger than the threshold value or when the application node 1 is forcibly executed, the data request is transmitted to the storage node 2 and the application node 1 executes the process. . If the data amount ratio is smaller than the threshold value, or if the setting is forcibly executing processing in the storage node 2, a processing request is transmitted to the storage node 2.
- the criteria for performing processing in the application node 1 or processing in the storage node 2 can be changed for each processing content. This is because, for example, when the process execution unit of the application node 1 is configured to perform high-speed processing for a specific process P as compared to the process execution unit of the storage node, the program that performs the process P is only the application node. It is possible to do so.
- the application node stores the data amount before and after processing, calculates the data amount ratio, and determines the processing node.
- the storage node Although the mode of storing the data amount before and after processing, calculating the data amount ratio, and determining the processing node has been described, the present invention is not limited to this mode.
- a dedicated node (third node) for storing the amount of data before and after processing, calculating the data amount ratio and determining the processing node is installed, and the application node and the storage node communicate with the dedicated node and Processing may be performed.
- communication between the application node or storage node and the dedicated node occurs, but since this communication amount can be realized with several bytes to several hundred bytes, the difference in data amount before and after processing is several kilobytes. There is no change in that the total amount of communication in the exceeding system can be reduced.
- the present invention can be applied to a general system that determines which node executes processing in a system in which one of the two nodes having resources capable of executing processing has processing data.
- the server has data between the mobile terminal and the server
- the present invention can be applied to a system that determines which of the mobile terminal and the server executes processing.
- the present invention can be applied to uses such as distributed computing. Moreover, it is applicable also to uses, such as a distributed process between a portable terminal and a server.
