BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a schematic configuration of a distributed computing system according to the present embodiment.
[0012]
As shown in FIG. 1, the distributed computing system according to the present embodiment is schematically configured by a server 50 connected to a network 100 and a mobile phone 10 (user mobile phone, mobile terminal) as a client. The server 50 having an application includes an information processing device (not shown) such as a workstation, and the mobile phone 10 has client software including an agent having a communication function and a job execution program.
[0013]
The server application of the server 50 divides the requested calculation process into units of a predetermined scale (for example, data size), and manages the progress of the process, the purpose of the process, and the like. In addition, in response to a request from the mobile phone 10 having client software, the processing unit 70 is delivered to the client mobile phone 10. Further, in order to pay for the processing, information of which client's mobile phone 10 has processed the processing unit 70 is also managed.
[0014]
The mobile phone 10 is connected to the server 50 via the network 100, processes the processing unit 70 transmitted from the server 50 by the operation of the client software, and transmits the processed unit 71 of the processing result to the server 50.
[0015]
FIG. 2 is a diagram showing an example of the selection screen 10a of the processing unit 70 in FIG.
The selection of the processing unit 70 in the mobile phone 10 will be described with reference to FIG.
[0016]
A selection screen 10a for processing purposes 1 to 3 is displayed on the mobile phone 10 as a client, and a user selects a processing purpose. The processing purposes 1 to 3 cover various fields such as “chemical purpose”, “medical purpose”, and “economic forecasting purpose”, and can be narrowed down to a specific processing purpose from these.
[0017]
In the present embodiment, it is assumed that the operator of the server 50 has a request for processing on the premise of multiple purposes (many processing purposes) from a client company, and a client using the mobile phone 10 (meaning a client for the server). This is a setting for preventing the mobile phone 10 from being used for a purpose not intended by the user (client) because it is difficult to determine the content of the process.
[0018]
FIG. 3 is a diagram showing an example of the setting screen 10b related to the processing unit 70 of FIG.
[0019]
As shown in FIG. 3, a setting screen 10b is displayed on the mobile phone 10, and processing settings relating to processing conditions by the user are registered in advance. Here, the setting is made in accordance with the usage state of the mobile phone 10, such as whether to perform the process during the time zone 10c, during the charging 10d, or during the standby 10e.
[0020]
This is because there is a possibility that a large amount of power of the mobile phone 10 may be used because the calculation process uses a lot of resources of the mobile phone 10 such as a CPU. Based on the setting here, the mobile phone 10 performs processing only when the setting condition is met.
[0021]
Next, the operation of the distributed computing system according to the present embodiment will be described with reference to the drawings.
[0022]
Based on the selection results and the setting conditions shown in FIGS. 2 and 3, the mobile phone 10 issues a processing request to the server 50.
[0023]
FIG. 4 is a diagram showing an example of the operation of the mobile phone 10 of FIG.
The mobile phone 10 keeps waiting until the condition is satisfied based on the setting contents (step 101), and checks the state whether the processable condition is satisfied (step 102).
[0024]
In step 102, when the condition that can be processed is satisfied (processing is possible in the figure), the mobile phone 10 of the client checks whether there is a processing unit 70 that has already been acquired (the processing unit in the figure exists). ?) (Step 103).
[0025]
If the processing unit 70 has been acquired or is in the process of being processed (in the figure, there is), the mobile phone 10 starts the calculation processing or continues the calculation processing (step 105).
[0026]
When the state of the mobile phone 10 is changed due to an incoming call or the like during the processing (step 106), the calculation processing is continued according to a preset corresponding processing procedure, or the calculation processing is interrupted and the processing returns to step 101.
[0027]
The calculation processing is continued, and after the processing is completed, the processed unit 71 is transmitted to the server 50 (step 107) and waits (step 108).
[0028]
If the processing unit 70 does not exist in step 103 (none in the figure), the client mobile phone 10 accesses the server 50, requests a new processing unit 70, and acquires the processing unit (step 104).
[0029]
At the time of the request from the processing unit 70, a request is made for a process that matches the already set processing purpose. If a processing unit 70 that meets the conditions is not found, the client mobile phone 10 shifts to the standby state of step 101 as an acquisition failure. When the acquisition of the new processing unit 70 is successful, the mobile phone 10 of the client proceeds to step 105 and performs a calculation process.
[0030]
In this embodiment, in order not to complicate the mutual management system for the processing unit 70 in the server 50 and the mobile phone 10, the mobile phone 10 performs the processing of one processing unit 70. With the increase in memory capacity, a plurality of processing units 70 can be stored in the mobile phone 10 and processed.
[0031]
FIG. 5 is a diagram showing an example of the operation in the server 50 of FIG.
[0032]
The server 50 receives the request of the processing unit 70 from the client mobile phone 10 (request from the client) (step 501).
[0033]
The type of the requested processing unit 70 is determined (request type confirmation) (step 502). This type is a processing purpose preset on the client side.
[0034]
The server 50 searches the processing unit 70 in response to the processing request and determines whether there is an unprocessed processing unit 70 (is there an unprocessed calculation unit?) (Step 503).
[0035]
If there is an unprocessed processing unit 70 (there is one in the figure), the corresponding processing unit 70 is transmitted to the mobile phone 10 of the client (the calculation unit is transmitted to the client) (step 504).
[0036]
If there is no unprocessed processing unit 70 in step 503 (none in the figure), it is transmitted to the client mobile phone 10 as no processing unit 70 (step 504).
[0037]
FIG. 6 is a diagram showing another example of the operation in the server 50 of FIG.
[0038]
The server 50 receives the processed unit 71 from the client mobile phone 10 (reception from the client) (step 511).
[0039]
The received processed unit 71 is confirmed, and the information of the client using the mobile phone 10 processed for payment of the consideration is stored (step 512).
[0040]
Further, the server 50 checks the existing processed units 71 and checks whether all the processed units 71 are present (processing unit completed?) (Step 513).
[0041]
If all the processed units 71 are present (completed in the figure), the processed units 71 are combined and stored as a processed completed unit (step 514).
[0042]
In step 513, if all the processed units 71 are not present (No in the figure), the processing ends and the reception of the processed unit 71 is waited (not shown).
[0043]
The above processing is repeated and the processing proceeds.
[0044]
FIG. 7 is a diagram showing an application example of FIG.
In FIG. 1, the mobile phone 10 (mobile terminal) is configured to be connected to the server 50 via the network 100 (Internet). However, in this application example, the mobile phone 10 is a communication carrier within a communication carrier. The server 50 (communication carrier server) is connected via the network 102.
[0045]
The server 50 is connected to a network 100 such as the Internet, and allows a terminal (not shown) from a customer company to refer to and download processing information including the processing completion unit and processing progress stored in the server 50.
[0046]
Since the distributed computing system according to the embodiment is configured as described above, the following effects can be obtained.
[0047]
The mobile phone 10 receives the processing unit 70 from the server 50 via the network 100. The mobile phone 10 processes the processing unit 70 to create a processed unit 71. The mobile phone 10 transmits the processed unit 71 to the server 50 via the network 100. By incorporating the mobile phone 10 into the distributed processing terminal in this way, an increase in the absolute time available for distributed processing can be expected.
[0048]
In addition, the system providing side having the server 50 sells the computing capacity to the customer company, and the user of the mobile phone 10 is paid for the processed amount of calculation (processing amount). By using the identifier, it is possible to construct a system in which the mobile phone 10 can easily charge the server 50 (the user is paid).
[0049]
Further, in addition to the system that connects the mobile phone 10 to the Internet through the communication carrier server described in FIG. 1, a server application that can manage distributed processing in a communication carrier server of a communication company that manages the mobile phone as shown in FIG. If introduced, the connection between the mobile phone 10 and the server 50 (communication carrier server) is a dedicated line within the communication carrier, so that security can be easily ensured.
[0050]
In the present embodiment, the mobile phone 10 having calculation processing means such as a CPU has been described. However, a mobile phone that constantly transmits and receives data using a wireless line (power is always on) is used. Similar effects of the terminal can be expected. Also, a charging time without carrying the mobile phone 10 can be expected as an effective processing target time.
[0051]
