DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing system for executing a data processing request transmitted via a network such as the Internet. The present invention relates to a means for efficiently cooperating with a support data processing device when the capability is exceeded.

[0002]

2. Description of the Related Art When a user executes certain data processing in a data processing device, the maximum value of the processing scale defined by the required memory size and the number of repetitions of calculations is mounted on the data processing device. The processing power of the processor,
It is determined by the scale of the data processing device such as the memory capacity and the disk capacity.

A technique for transferring data processing to another device when the size of the data processing request exceeds the capacity of the data processing device of the data processing center is disclosed, for example, in Japanese Patent Laid-Open No. 6-2150.
No. 31 is described. In this conventional technique, the data processing itself is transferred to another processing device and executed, so a larger-scale processing device is required depending on the scale of the data processing.

[0004] When processing data by accessing a data processing device of a data processing center via a network such as the Internet, use limited software of the data processing center with a WWW (World Wide Web) browser. With the permission of the data processing center, the user directly logs in to the data processing system, and processes data using commands prepared in the data processing device.

[0005]

The scale of data processing is
When the capacity of the data processing device of the data processing center is exceeded, that is, when the data processing center cannot execute the data processing, the user can give up the data processing itself or execute the data processing. Search for another data processing center with a suitable data processing device,
The data had to be processed with a lot of time and effort, such as signing a new usage contract. What the user originally needs is the result of the data processing, not the creation of an environment for processing the data. Therefore, how to secure data processing resources necessary for data processing so that the user can concentrate on only data processing is an issue.

Further, the following two problems arise in the system utilizing the data processing center. First, the use of only a WWW browser limits the software that can be used.
That is, the functions of the data processing system capable of performing various processes cannot be sufficiently utilized. Second, in the case of a data processing system that logs in and uses the data processing system directly, it may be possible to access data of other users, and conversely, there is a possibility that other users can see their own data. There is a security problem.

[0007] For this reason, in order for a user to use a data processing device available via a network such as the Internet with a sense of security, a command typing method for giving the impression of being directly logged in is used. Therefore, it is necessary to restrict data access by limiting the data access range to the user.

An object of the present invention is to provide means for securing data processing resources necessary for a user to perform data processing comfortably even when the scale of a data processing request exceeds the capacity of a data processing device of a data processing center. To provide a data processing device.

[0030]

Second Embodiment FIG. 2 is a block diagram showing a system configuration of a data processing system according to a second embodiment of the present invention. The data processing system of the second embodiment is an embodiment in which billing means for operating the data processing system with an unspecified number of third parties as users is added to the basic configuration of the first embodiment.

The user operation unit 110 of the user computer 100 includes a command input unit 111 and an output unit 113
In addition, the input history operation means 112, the priority application means 114, the file transmission means 115, the file reception means 116, the billing display means 117, the input data file (120), and the output data file (130) And

The service providing means 210 of the service providing apparatus 200 includes, in addition to the command analyzing means 211, the processing scale determining means 214, and the execution instruction issuing means 215, a command recording means 212, an execution permission determining means 213, and a processing result receiving means. Means 216, processing result transmitting means 217, priority changing means 218, charging processing means 219, user authentication means 220, command DB 221, history DB 22
2, a log DB 223, a billing DB 224, and a user D
B225.

The main data processor 0 (500) includes a linking unit 511, an arithmetic processor 512, and an execution unit determining unit 51.
5, in addition to the user file storage area 550, the priority changing means 513, the processing recording means 514, the input data file 0 (520), and the output data file 0 (530)
And a log DB0 (540). The user file storage area 550 stores an input data file 560 and an output data file 570.

The support data processing device 1 (600) includes, in addition to the linking means 611 and the arithmetic processor 612, a priority changing means 613, a processing recording means 614, an input data file 1 (620), and an output data file 1 (630),
Log DB1 (640).

The other support data processing devices 2,..., N (70
, 710) have the same configuration as the support data processing device 1 (600).

FIG. 3 is a block diagram showing a distributed processing procedure when operating the data processing system of the second embodiment in order to simultaneously execute a parameter survey by a plurality of processors with as little labor as possible. More specifically,
This is an example in which when calculating the deformation of the cantilever, ten cases of t = 1, 2,..., 10 are calculated using the thickness t of the beam as a parameter.

The user inputs the base input data 5600,
A parameter file 5601 is prepared. The base input data 5600 is a data file in which one of the 10 cases is set.
01 is the parameter change contents t = 1, t = 2,..., T
= 10 is a data file describing the data file. The parameter file 5601 only needs to describe the changed part of the base input data, and requires much less labor and file occupancy compared to the case where input data is prepared for all cases of the parameter survey. The individual file creating means 5650 creates an input data file corresponding to each parameter from the base input data 5600 and the parameter file 5601, allocates these to a plurality of processors 51201,. Obtained result file 57001
, 57010 are collected under the user name by file transfer.

Normally, the number of parameters is not one, but several parameters are set to several values, and one parameter survey is often made by combining the parameters. In this case, the total number of cases may be in the range of thousands to tens of thousands, and the processing cannot be performed by only one processor. Therefore, it is important to shorten the processing time by parallel distributed processing.

FIG. 4 is a diagram for explaining the effect of shortening the processing time according to the present invention. In the cantilever example, if 10 cases are executed by only one processor, almost the same
This is repeated 0 times, requiring 10 times the processing time of one case.

On the other hand, in the second embodiment, the files are made independent for each case and processed by different processors, so that even 10 calculations can be processed in one case. In the case of parameter survey, if you prepare a data file for each case,
The respective calculations are independent of each other, and the effect of the parallel / distributed processing is very high. To improve the analysis accuracy, the amount of parameter change must be reduced, but conversely, the total number of cases increases by multiplying the number of parameters, so parallel and distributed processing is a very effective means. Become.

Since the transfer time of the input data and the output data is much shorter than the processing time of the above one case, the effect of the transfer time on the entire processing time is as follows.
In fact, it can be ignored.

FIG. 5 is a diagram for explaining a processing procedure for creating individual input data according to each case. here,
There will be described a case where there are two parameters, each of which is changed to two types of values. In technical calculations, base input data is almost always described in text format.
The parameter file 5611 contains the base input data 5
The number of lines 610 and how to change the numerical value described in that line are described.

In FIG. 5, the second data in the tenth row is 1
An instruction is written to change to two types of 00 and 200 and to change the third data in the 20th row to two types of 80 and 90. In addition, each change instruction is labeled A and B, and the following "combination = A,
The line “B” is an instruction for combining these two change instructions. Therefore, the combinations are (100, 80),
(100,90), (200,80), (200,90)
Kind.

The individual data is generated by first copying the entire block from the base input data to the ninth line which is not changed, that is, the entire block into a new file, adding the first data on the tenth line, and then adding the second data on the tenth line. Is extracted from the parameter file 5611 and added. Thereafter, the remaining part of the tenth line is copied from the base input data 5610 to create data up to the tenth line. Hereinafter, similarly, change processing is performed up to the 20th line, and the rest is copied to obtain individual data 1 (56101). Similarly, a file is created for other change data, and four types of individual data files are created.

Next, the operation of the entire data processing system according to the second embodiment will be described by taking a parameter survey process as an example. The user describes the name of the program to be executed and the file name of the input data 120 in the form of a character string in the command input unit 111, and transmits it as a processing request.

The command analyzing means 211 of the service providing means 210 receives the transmitted processing request, decomposes a character string given as a command into words or characters, and executes a program name, an input data file name, a degree of parallelism, Analyze the host name.

The processing scale determining means 214 determines whether or not the processing can be executed by the main data processor 0 (500) based on the degree of parallelism.

When it is determined that the execution is executable, the execution instruction issuing means 215 copies the input data 120 to the user file storage area 550 in the main data processing apparatus and executes the processing for the main data processing apparatus 0 (500). Is created and transmitted to the main data processing device 0 (500).

After receiving the execution command, main data processing apparatus 0 (500) performs this execution processing. Output data 570 generated as a processing result is stored in the user file storage area, transmitted to the user computer 100 via the processing result receiving unit 216 and the processing result transmitting unit 217 of the service providing unit 210, and output to the user computer 100. Displayed at 113 or copied to output data 130.

At this time, when a part of the data file of the processing result includes confidential information regarding the data processing device, the processing result transmitting means 217 transmits the processing result to the user except for this, thereby ensuring security. .

If the main data processing unit 0 (500) alone does not have enough arithmetic processors for parallel processing, the processing scale determination means 214 determines whether the main data processing unit 0 (500) and the support data processing unit 1 (600) A cooperation instruction is issued, and each of the cooperation means 511 and 611 changes the configuration of the arithmetic processor. As a result, the arithmetic processors 512 and 612 can be handled as one processor group, and can provide processing power stronger than that of the main data processing device 0 (500).

When the preparation for the cooperative processing is completed, the execution instruction issuing means 215 sets the main data processing apparatus 0 (500).
Issue the execution command. The input data 120 is stored in the user file storage area 550 in the same manner as described above.
During the cooperative processing, the input data 0 (520) directly handled by the arithmetic processor 512 of the main data processing apparatus 0 (500) and the support data processing apparatus 1 (60)
0) input data 1 (62
0) is temporarily created.

Each of the arithmetic processors 512 and 612
The processing is executed based on the respective input data 520 and 620. The result generated in each process is created as output data 0 (530) and output data 1 (630). Thereafter, the main data processing apparatus 0 (500) creates output data 570 as an overall result of integrating them. The output data 570 is sent to the user computer 100 via the service providing unit 210, and the output data 130 is created.

Next, a description will be given of a processing procedure of a command operation for the user to confirm the execution state of the processing request and the like. The user describes a command such as a status check in the command input unit 111 and transmits the command to the service providing unit 210. As in the case of executing the above technical calculation program,
The transmitted command character string is stored in the command analysis unit 211.
Is decomposed into words.

The execution permission determining means 213 identifies a command and an operation target from the decomposed individual words, and determines whether the command permits the user to execute or whether the operation target is the user's own. Only when the executable command and the operation target are the user's own, the execution instruction issuing unit transmits the command to the main data processing apparatus 0.
(500) for immediate execution. Commands usable in the main data processing device 0 (500), the support data processing device 1 (600), and the like are stored in the command DB 221 together with a flag indicating whether the user can execute the command. The execution permission determining unit 213 refers to the command DB 221. Then, it is determined whether execution is possible.

The execution result of the main data processing device 0 (500) is displayed on the output means 113 of the user operation means 110 via the service providing means 210. Since a series of these processes are executed immediately instead of in a batch format, the process from the command transmission by the user operation unit to the display of the result is executed in a short time, and the user operates the main data processing device 0 (500).
You can feel as if you are directly using.

On the other hand, when the command is not executable by the user or when the operation target is not the user's own, the execution permission determining unit 213
5 is notified of the prohibition process, and the execution instruction issuing unit 215 issues a command execution stop notification and an execution disable notification to the user. The prohibited items include, for example, moving a directory to another user's file storage area, referring to another user's file storage area, checking the status of another user's execution program,
Direct login to the main data processing device 0 (500) and the support data processing device, and the like correspond.

Next, the history recording of the processing request will be described. Regardless of the execution of the technical calculation program and the acquisition of information for state confirmation, all commands input to the command input unit 111 and transmitted to the service providing unit 210 are stored in the history D.
B222. In the history DB 222, an input command character string and an end code of an execution result are recorded as a pair. The command character string is stored in the user operation unit 11.
0 can be displayed on the input history operation unit 112, and can be copied to the command input unit 111 by a character string selection operation by pressing a pointing device such as a mouse or a key on a keyboard, and the same operation can be repeated with a small number of operations.

The end code in the history DB 222 is added to classify a normal end, an abnormal end, or an unexecutable state. The normal end is added when the program ends normally according to the input data, or when a status confirmation command or the like is executed correctly. Abnormal termination is added when the data processing device or the executed program detects any abnormality or an abnormal state occurs during the execution of the processing and does not terminate normally. Unexecutable is added for a command corresponding to a prohibited item.

By checking the contents of the history DB 222, it is possible to point out the possibility of unauthorized use when a large number of commands to which execution is prohibited are recorded.

Next, recording of processing will be described. Main data processor 0 (500), support data processor 1 (60)
0) records the execution record in the log DB0 (540) and the log DB1 (640) when the user's processing request is executed. Items to be recorded include the executed device, reception time, processing start time, processing end time, processor usage time, memory usage, disk usage, usage unit price, priority information, and the like. Each data processing device transmits an execution record of the process to the service providing unit 210 at the end of each process, and the service providing unit 210 collectively records usage information for each user in the log DB 223.

Next, the unit price change and the priority change when the technical calculation program is executed will be described. The user pays a fee according to a predetermined unit price and the contents of the log DB 223 described above. However, if you want to finish highly urgent processing sooner,
You may want to increase the priority within the data processing device. In order to respond to such a request, the service providing unit 210 includes a priority changing unit 218.

The priority changing means 218 stores the correspondence between the unit price and the priority in a table or a monotonically increasing function, and the higher the priority, the higher the unit price. Conversely, lowering the priority also lowers the unit price of use and slightly increases the processing time, but makes it possible to process data at low cost. If one of the priority and the use unit price is changed, the other is determined by the correspondence.

When changing the priority, the user changes the priority or the unit price using the priority application unit 114 of the user operation unit 110. The priority or unit price set here is sent to the main data processing apparatus 0 (500) via the priority changing means 218 of the service providing means 210. In the main data processing apparatus 0 (500), when a user's processing request is started, the priority changing means 513 changes the priority. Similarly, when the processing is shared by the support data processing device 1 (600), the priority change unit 613 changes the priority of the processing in the support data processing device 1 (600).

When a plurality of users send processing requests of the highest priority and a processing capacity that satisfies the request exceeds the capacity of all the cooperable data processing apparatuses, the priority changing means 218 sets The priority of each user is reduced uniformly, and adjustment processing is performed so that the required capability falls within the capabilities of all data processing devices. At this time, the unit price initially set by the user (or the unit price determined by the priority when the priority is set first) is reduced in accordance with the correspondence by the process of lowering the priority.

FIG. 6 is a diagram for explaining in detail the command analysis processing procedure and the determination of execution permission. The command analysis unit 211 decomposes the processing request command 201 sent from the user into individual words or a set of words.

In FIG. 6, "program1" (202) is the execution program name, "-n64" (203) is the number of processors used (64 in this case), and "-if datafil"
e "(204) is the input data file name, and" -ip pa
"rmfile" (205) is the parameter file name.

The execution program name 202 is compared with the contents of the command DB 221 by the execution permission judgment means 213. The command DB 221 has a file name
(file column), system flag (system column), executable host
(license column), executable user name (user column), etc. are registered. If the system flag is set,
Indicates that only the system administrator ID can be executed.
When the host name is written in the license column, only the host on which the host is written is executable, and when all is written, it indicates that all hosts are executable. user
Similarly, the column indicates an executable user. The execution permission determining unit 213 stores the execution program name 202 in the command DB 22
In step 1, the executable host and the executable user are checked to determine whether or not the execution is possible.

The processing scale determining means 214 compares the number of processors 203 with the number of processors of the main data processor 0 (500) to determine the processing scale. The input data file name 204 and the parameter file name 205 are sent to the main data processing device 0 (500) when the program is executed.

FIG. 7 is a block diagram for explaining a cooperative processing system of a plurality of data processing devices. FIG. 7 illustrates a case where the main data processing apparatus 0 (500) can provide up to 32 processors, and here is requested to perform data processing by 64 processors.

The main data processing device 0 (500) is responsible for 32 of the 64 data processes, and executes the processing of the missing 32 data processes.
0) is requested to secure 32 processors. The cooperation means 511 and 611 of each data processing device
This cooperation process is executed while communicating.

In response to the support request from the main data processing unit 0 (500), the support data processing unit 1 (600) checks the operating status of the processor in its own device, secures the processor, and sends it to the main data processing unit 0 (500). Execute the notification of the completion of preparation.

After receiving the preparation completion notification from the support data processing apparatus 1 (600), the main data processing apparatus 0 (500)
Are input data 00 (52000) to input data 31 among the individual files generated according to the input data 560.
(52031) in its own device and the remaining input data 32
(62000) to input data 63 (62031) are sent to the support data processing device 1 (600).

After receiving the input data 32 to 63, the support data processing device 1 (600) starts processing immediately. After executing the processing, the support data processing device 1 (600)
Generated output data 32 (63000) to output data 6
3 (63031) is transmitted to the main data processing device 0 (500).

The main data processing apparatus 0 (500) outputs the output data 00 (5300) of the data processing executed by its own processor.
0) to output data 31 (53031) and the output data 32 to 63 transmitted from the support data processing apparatus 1 (600) are combined and stored in the user storage area 550 as the entire output data 570.

When all the above processes are completed, the input data 00 to 63 and the output data 00 to 63 used for the individual data processing are deleted from the respective data processing devices.
