Abstract

(57) [Abstract] [PROBLEMS] When processing data generated by a plurality of computers connected to a network is collectively managed by a single computer and the data is uncertain and huge data is generated, To obtain a data management device for efficient management. SOLUTION: When a computer user creates data by using processing software, disk management data such as b is prepared, and a margin area such as 4 which is determined in advance for each individual user is exceeded. If it becomes necessary to borrow the margin area of another user by storing the user names of the borrowing source and the borrowing destination and their capacities as shown in d, the margin area of the other user is stored. When data is re-allocated, temporary data is stored, and the data is saved to another storage medium and the borrowing is no longer necessary, a data management method is adopted such that the data indicating borrowing is erased like e.

[0002]

2. Description of the Related Art Conventionally, in the field of computers such as personal computers and workstations, networking of a plurality of computers has been advanced so that users of computers can mutually share processing data of other computers. Has been done.

FIG. 6 is a diagram showing a computer system in which a plurality of computers are connected by a network. In FIG. 6, 37 to 39 are user computers connected to the network, and 40 is a computer on another user side. A data management device as a shared data storage device for collectively managing the data created as the processing result, and 41 is a network for connecting the computers. In this way, by connecting a plurality of computers to the network and using the magnetic disk of one computer as a shared data storage device of another computer, for example, the data processed by the computer 37 is processed by the data management device 40 via the network. To the shared data storage device, and the stored data is stored in the computer 3
It becomes possible for 8 users to reuse. The computer 40, which is the shared data storage device, will be referred to as a data management device and will be described below.

The data management device 40 is installed in a network and collectively manages data processed by other computers to share the data among a plurality of computers. FIG. 7 shows such a structure. In FIG. 7, reference numeral 24 denotes a display device for the user to confirm the progress of the processing while displaying the progress of the processing of the computer at any time.
5 is an arithmetic unit for actually performing arithmetic for computer processing, 2
6 is an input device for the user to input a processing instruction to the arithmetic unit 25, 27 is a first storage device called a memory for temporarily holding the processing contents during the calculation, 28 is the processing results of a plurality of computers Is a second storage device as a shared data storage area for storing the data, and a magnetic disk device is usually used. Reference numeral 29 is a disk usage state detecting device for detecting the data capacity, used area, unused area and owner of each data, creation date and time of the second storage device 28, and 30 is detected by the disk usage state detecting device 28. A warning display device for giving a warning notification to the computer user according to the state, and a data saving storage device 31 for saving the data overflowing the second storage device 28 are usually a magnetic tape device. This data management device 40 has the same configuration as the other user computers 37 to 39, except that the data management device 40 is provided with a second storage device 28 for sharing data and a disk usage state detection device 29 for sharing. It has a function.

Next, the operation from the input to each computer to the storage of processed data in the computer system shown in FIG. 6 will be described with reference to FIG. First, when the user inputs the content to be processed from the input device 26 as a processing instruction, the arithmetic unit 25 starts executing the processing software corresponding to this instruction, and while the arithmetic unit 25 proceeds with the processing, The intermediate data is stored in the first storage device 27, and the second storage device 28 is used as input data for the process.
To call data as needed. When the processing software includes a storage command and the arithmetic unit 25 executes the storage command to the second storage device 28 of the data management device, or when the processing is completed and the user operates the input device 26, a data storage instruction is issued. If it is written, it will be written. It should be noted that the disk usage state detecting device 29 determines the capacity of the used area in which data is stored in the second storage device 28, the capacity of the unused area in which data is not yet stored, and the already stored data. It is possible to detect the capacity and the date of creation, provide information for data management, and issue various warning messages regarding data management by the function of the warning display device 30 as necessary. Reference numeral 31 is a storage device to be used as a data saving place when data overflows in the second storage device 28, and an inexpensive magnetic tape device is usually used.

By the way, the data management apparatus 40 divides the storage area into each computer user in advance and allocates the storage area in order to store the processed data of each computer in the second storage device 28.
It has a function of storing the computer processing data of the corresponding user only in the allocated area. Here, a conventional method of allocating a storage area of the second storage device 28 and storing data will be described with reference to FIG. In FIG. 8, the storage area of the second storage device 28 is logically represented by a bar shape with respect to the capacity. First, (o) does not use the function of dividing and allocating the storage area of the second storage device 28 for each user computer as the data management function described above, but processing data 42 to 44 of each computer in the order of occurrence. It is a method of sequentially storing. (P) is a case where the function of dividing and allocating the storage area of the second storage device 28 is used, and the second storage device 28 of the data management device is equally divided by the number of user computers. Among them, computer users can freely use the data. (Q) is an additional function of (p), and is a save area when data overflow occurs in a storage area divided for each user.
It has a fixed margin of. In (r), the processing software causes the second storage device 2 to store the data in the middle of processing at a certain number of times of operation or the operation time of the input device 26 of FIG. 7.
8 has a function of storing the data in the storage device 8, and the arithmetic unit 25 which has received this command stores the in-process data 48 stored in the first storage device 27 in the second storage device 28, and then the disk usage state detection device. With the function of 29, the capacity of the unused area such as 47 is notified to the user by the function of the warning display device 30.

The conventional data management apparatus has been configured as described above, but depending on the type of software of the computer, the data capacity generated after the processing is difficult to predict before the processing is executed. For example, in conversational software represented by a word processor, the input device 26 of FIG. 7 such as a keyboard or a mouse is operated for character input or graphic editing. Since the operation time and the data volume change in a form that maintains a substantially linear shape, it is easy to predict the generated data volume. However, simulation software that simulates various natural science and social science phenomena on a computer and tries to predict the consequences of such a phenomenon is difficult to predict the amount of data that will occur. FIG. 9 shows a work flow when the computer user uses the simulation software. In FIG. 9, 49 is a step of formulating a problem in which a mathematical solution for simulating a phenomenon to be predicted and deriving a phenomenon prediction is derived, and 50 is data which a computer can process by the method found in the problem formulation 49. , 51 is a step of creating a model for mathematically modeling the constraint conditions of the phenomenon to be simulated, 51 is a step of actually executing simulation to derive a phenomenon prediction, and 52 is a step of verifying whether the derived phenomenon prediction is desirable. is there.
In addition, 53 is model creation 5 when the phenomenon prediction is not desirable at the stage 52 of verification of simulation results.
It returns to the stage of 0, and the constraint conditions are corrected again in the model creation 50, and the model creation 50 to the simulation result verification 5 are performed until a desired result is obtained.
The processes up to 2 and 53 are performed recursively, and under what kind of constraint conditions a desirable result is obtained.

For example, taking the vibration simulation of a structure as an example, if the frequency range of the vibration generated in the operating environment in which the structure is operated is predicted and set by experiments or the like, the shape of the structure is determined within that frequency range. It is impossible to predict how many and how many resonances will be significantly distorted unless simulation is performed. Therefore, in FIG. 9, data such as a deformation diagram showing the degree of distortion of the structure in the resonance frequency region can be predicted only in number after the simulation execution 51 is completed.

The work flow of the user of the simulation software of FIG. 9 will be described with reference to FIG. 7 in comparison with the process flow when the computer processes it. Problem formulation 4
With respect to 9, the mathematical solution for deriving the phenomenon prediction is created as the processing content of the operation processing 25 as processing software. The user creates the model 50 by using the input device 26.
Is operated interactively to send a processing command to the arithmetic unit 25, and the arithmetic unit 25 receives the contents of the operation to create a model in which the constraint conditions are expressed by a computer, and the model creating process is displayed on the display unit 24 for use. To confirm. As for the process of model creation 50, since the process proceeds in an interactive manner, the data capacity changes in a manner that maintains linearity as in a word processor. With respect to the data of this model, the user performs an input operation of a command to be stored in the data management device as needed, and the arithmetic unit 25 receives the contents of this operation and stores the data in the second storage device 28 of the data management device. Remember. Next, for the simulation execution 51, the user operates the input device 26 to send a simulation execution command to the arithmetic unit 25, the arithmetic unit 25 calls the processing software and starts the process, and the model is created 50. The model is called from the second storage device 28, the processing is advanced while the mid-process data is stored in the first storage device 27, and the processing result is derived as the phenomenon prediction. Regarding the simulation execution 51, there is a waiting time as a result on the user side from the issuance of the execution start command to the end of the processing, and the operation of the input device 26 is not necessary. When the processing result of execution 51 of the simulation is obtained,
This result data is stored in the second storage device 28 of the data management device 40, which is called, and the processing result is displayed on the display device or the like at the stage of verification 52 of the simulation result to validate the processing result as a phenomenon prediction. The user verifies the sex. In the verification 52 of the simulation result, if the verification result is not desirable, the user operates the input device 26 to call the model information stored in the second storage device 28 in advance and correct it. Then, the model creation 50 is performed again and the subsequent steps are recursively performed. In addition, from model creation 50 to verification of simulation results 52 and 53
In the case of performing the recursive processing up to, it is often the case that the previous processing contents are retained and the simulation is executed again under different constraint conditions, and additional editing is performed on the same data. As the number of such processes increases, one data capacity will increase in sequence.

As described above, as a data management device for processing data whose generation amount cannot be predicted, the following problems occur in the conventional data management method. First, in the method shown in FIG. 8 (o), when data overflow occurs in a magnetic disk having a limited capacity, all users of the data management apparatus cannot store new data. In the method of dividing and allocating the second storage device 28 of the data management device for each user (p), even if data overflow occurs in the allocated user personal area, it does not affect other users. Although there is an advantage that the data can be localized, if this overflow occurs, other data is temporarily saved in another storage medium such as the data save storage device 31, and the simulation is performed after securing an unused area where the data can be stored. Must be re-executed, resulting in a long waiting time being wasted. On the other hand, in the method of giving a certain margin to each user of (q), the amount of data to be generated is unpredictable. Become. (R)
In the case of interactive software such as the word processor described above, in the method of (1), since the amount of data changes in a manner that maintains linearity with respect to the number of operations of the input device or the operation time, a certain number of operations Alternatively, if the user is informed of the remaining amount of the unused area after storing the in-process data in the second storage device 28 of the data management device for each operation time, the user can handle it and how much operation It is possible to determine whether a data overflow will occur, interrupt the operation, and save other data in advance, thereby minimizing waste of processing time. However, in the case of a process such as the simulation execution 51 of the simulation software shown in FIG. 9 in which the amount of generated data is unpredictable, the user cannot determine whether or not the data overflow occurs, and thus the overflow is still caused by this method. As a result, waiting time is wasted.

[0011]

The present invention has been made to solve such conventional problems. By efficiently managing the processing result data generated by the computer processing software, the waste of the processing result waiting time of the computer processing software is minimized.

Means for storing and erasing the data stored in the second storage device 28 is provided.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1. In the method of (q) in FIG. 8 in which the storage area of the second storage device 28 of the data management device is divided and assigned in advance for each user, and the individual areas are each provided with an allowance, If there is data that exceeds the limit, the data that can be saved must be saved in the data saving storage device 31, a storage area must be secured, and the processing must be re-executed.
The waiting time for the processing result is wasted. In order to avoid this, the present invention provides the arithmetic unit with means for allocating the margin of another user and temporarily storing it when data exceeding the margin is generated.

FIG. 1 shows a second storage device 2 of the data management device.
It is the figure which showed the whole area | region of 8 logically by the rod shape with respect to capacity. (A) and (b) are data 1 newly computer-processed, data 2 edited by existing computer, or data 3 saved in another storage device,
The table of (b) in which the used area, the unused area, the margin area, and the user name of the lending partner when the margin area is lent to another user is described for each user in each case
The disk management data storage area is created and stored as shown in 7 in the storage area of the second storage device 28 by the function of, and in the table of FIG.
The capacity of each area is shown numerically, with the sum of the unused area and the margin area being 100. (C) and (d) show the case of storing the data 8 which cannot be stored unless the personal margin area generated as a result of the computer processing is used. The number is zero when the area disappears and the capacity is reduced by the amount used for the margin area, and the figure is entered in the term of the margin area. (E) and (f)
Shows a case in which the data 9 that exceeds the personal margin area generated as a result of the computer processing is stored, and the unused area of the user B disappears and becomes zero in the table of (f). The usage area includes the total usage amount of each individual user including those borrowed from other users, the remaining area of the borrowed area from the user C is included in the spare area, and the user B is included in the spare area of the user C. Since it is borrowed, 0 is entered, and the name of the borrowed user B is entered in the other user section. (G) and (h) show the case where the user B temporarily borrows the margin area of the user C until (e) and saves the data 10 in the data save storage device 31. Since the data 10 is saved, the data 9 is contained in the user's personal area, and it is not necessary to borrow the user C's allowance area, and the user B's allowance is shown in the table of (h). The capacity having a surplus in the area is put into the term of the margin area, the capacity of the margin area of the user C is returned to the original, and the terms of other users are deleted.

Due to the function of the disk usage state detecting device 29 of FIG. 7, in FIG. 1 (a), every time data is stored, edited, or saved, the user's used area, unused area,
The computing device 25 detects the margin area and outputs the information to the second area.
The data in the table (b) is stored in the disk management data storage area 7 of the storage device 28 as disk management data. When data such as the data 8 shown in FIG. 1C exceeds the unused area but falls within the individual margin area, the disk management data storage area 7 is stored in the same manner as in the case of FIG. After thickening the data in the table of (d) as disk management data, a warning of the disk capacity is issued to the user by the function of the warning display device 30. When it is necessary to borrow the data of other users beyond the individual margin such as the data 9 of FIG. 1 (e), the table of (d) prepared in advance is used to list all users. The operating condition of the spare area is searched and the user who does not use the spare area is searched for by the arithmetic unit 25.
The user C does not use the allowance area from the item of the allowance area in the table of (d), so that the allowance area of the user C is temporarily reassigned as that of the user B. , The user B of the borrower in the section of the other user of the user C
Is entered by the function of the arithmetic unit 25, the table of (f) is created, and stored in the disk management data storage area of the data management unit. When there is data to be saved while borrowing the margin area of another user like the data 10 in FIG. 1G and there is no need to borrow, the same as in the case of (a). A table such as (h) is stored in the disk management data storage area, and the term of another user of user C is calculated in order to return the spare area of user C lent to user B to the original user. It is erased by the function of the device 25.

By the function of the data management apparatus as described above, the data generated by the processing software, which is difficult to predict the amount of data generated before the processing is executed, dynamically resets the margin areas of other users. As a result, it can be temporarily stored, which has an effect of minimizing waste of the processing result waiting time.

Embodiment 2. In the first embodiment of the invention, the storage area of the second storage device 28 of the data management apparatus is allocated by dividing the storage area for each user, and the margin to store the overflow when a disk overflow occurs. Although the areas are managed as separate areas, the present invention creates an area corresponding to the margin area in the user's personal area and manages it as a resetting storage area.
Means for detecting the usage state of the storage device 28, means for issuing a warning, and means for allocating the resetting storage area of another user when data as a processing result exceeds the unused area including the resetting storage area Have.

With the function of the data management device as described above, the second storage is performed within the range of the user personal area initially assigned by all the users while maintaining the same effect as that of the first embodiment of the invention. When the device 28 is used, the entire storage area of the second storage device 28 can be used, and the restriction of the allowance area of the first embodiment of the invention can be avoided.

Embodiment 3 FIG. In general, a memory device formed of a semiconductor is more expensive than a magnetic disk device, and thus the storage capacity of the first storage device 27 is smaller than that of the second storage device 28. The maximum storage capacity of the first storage device 27 that holds the data in the middle of the calculation is focused on that the information in the middle of the process performed by the calculation device 25 is stored in the first storage device 27 of FIG. Since the data exceeding 1 cannot occur as a processing result, the present invention provides the second storage device 28.
Of the unused area of the first storage device 27 that is fixedly determined in the computer before the simulation is executed.
The maximum storage capacity of the second storage device 28 is compared with the maximum storage capacity of the second storage device 28, and the user is warned that there is a possibility of data overflow if the unused area of the second storage device 28 has a smaller capacity. As a result, the user follows the warning when data overflow may occur, saves other data before executing the simulation, and executes it, thereby eliminating waste of processing result waiting time.

FIG. 2 shows the first of the elements that make up the computer.
The storage device 27 and the second storage device 28 are represented by a bar shape with respect to the capacity, 11 indicates the capacity of the unused area of the second storage device 28, and 12 indicates the first storage device. In the middle of processing, which is temporarily stored in 27, 13 indicates the maximum storage capacity of the first storage device 27,
Reference numeral 14 is a warning when there is a possibility of data overflow, and data overflow may occur because the maximum storage capacity 13 of the first storage device 27 is larger than the unused area capacity 11 of the second storage device 28. It means that there is.
The maximum storage capacity 13 of the first storage device 27 is uniquely and fixedly determined in the computer. Immediately before the execution of the simulation software, the capacity 11 of the unused area of the user's personal area is detected by the function of the disk usage state detection device 29, and is compared with the fixed maximum storage capacity 13 of the first storage device 27. When the maximum storage capacity of the first storage device 27 is larger, the warning display device 30 is used to issue a warning to the user that data overflow may occur.

By the function of the data management device as described above, as the data management of the processing software in which the capacity of the data generated before the processing is difficult to predict, the upper limit of the maximum storage capacity of the first storage device 27 is used as a warning. By providing the above, there is an effect that other data saving is performed in advance before the processing is executed and the data saving is performed in advance to avoid waste of the processing result waiting time.

Embodiment 4 In order to prevent the data created by one user from occupying the storage area of another user significantly after performing the data management as in the first embodiment of the invention, the present invention is directed to another user. When the storage area is borrowed, a means for prohibiting creation and editing of data other than the latest data is provided. This is because the recursive process until the desired phenomenon prediction is obtained in the simulation software workflow of FIG. After passing data such as the constraint conditions to the subsequent process,
It is a task to obtain the desired result for each phenomenon such as simulating the next phenomenon and move to the next,
Regarding the phenomenon corresponding to the latest data that caused the overflow of data and required the borrowing of the storage area of another user, it is the data in the middle of work that has not yet obtained the desired phenomenon prediction,
It is assumed that the other data is the completion data which has obtained the desired result and passed the information to the subsequent process. Only the latest data can be edited when, while borrowing the storage area of another user, the completed data once handed over to the subsequent process is diverted to start a new operation or start a completely new operation. This is because it is necessary to prevent excessive consumption of the margin area of other users by prohibiting the use of the user and allowing only the work in progress to be completed.

In FIG. 3, when it is attempted to sequentially execute the simulation for the phenomena 15 to 17 of (i), the result data 18 to 20 are generated as the processing data, and the result data 18 to 20 It is a diagram of a case where the data is stored in an area, and execution of simulation other than phenomenon 16 is prohibited unless another data is saved and a storage area is secured.

In order to realize the above-mentioned function, every time data is stored, saved, or edited in the data management device, the function of the disk usage state detection device 29 of FIG. The creation date and time of all the data is detected as shown in the table of FIG. 2 (j), and whether the data corresponding to the phenomenon is the latest data before the simulation is executed. If the target data is not the latest, the simulation is prohibited, and the user is warned by the function of the warning display device 30 that the simulation cannot be executed.

By the function of the data management device as described above, when data overflow occurs and the spare area of another user is borrowed, it is possible to edit only the data for which work has not been completed. There is an effect that a user does not occupy the storage area of another user remarkably and more efficient data management can be realized.

Embodiment 5 FIG. As in the third embodiment of the invention, only the data in the middle of work can be edited, and then the model creation 50 of FIG. 9 showing the work flow of the simulation software for one phenomenon is verified from the simulation result verification 52 and 53. When the number of executions of this recursive work is allowed indefinitely with respect to the recursive work of, the number of combinations shown in FIG.
Therefore, the data capacity stored in the second storage device 28 increases and one user remarkably occupies the spare area of another user. In order to avoid this, the present invention relates to the latest data that causes data overflow in the user's personal area.
Model creation 50 to simulation result verification 5
A means is provided for setting the number of times of recursive processing up to 2 and 53 and for prohibiting execution of the simulation exceeding the number of times of cancellation.

Specifically, the table stored in the disk management data storage area of the second storage device created as shown in FIG. 1F is expanded in terms of the number of executions as shown in FIG. 4A. However, when the data overflow occurs, 1 is stored in the part of the user as the number of executions, and each time the simulation is executed thereafter, the number of executions data is increased by 1 as a function of the arithmetic unit 25 of FIG. , As disk management data in the disk management data storage area 7 of the second storage device 28. Further, before executing the simulation, the execution count of the table in (1) of FIG. 4 stored in the disk management data storage area is read out, and when 1 is added to this value, the initially set abort count is not exceeded. The arithmetic unit 25 checks whether or not, and if the number of times of termination is exceeded, the execution is prohibited, and the user is warned by the function of the warning display device 30 that the execution cannot be performed.

By the function of the data management device as described above, the overflow of data occurs and the spare area of another user is borrowed, and the number of times of re-execution of the process for one data is set to be aborted. Since the person does not remarkably occupy the storage area of another user, there is an effect that more efficient data management can be performed.

Sixth Embodiment According to the present invention, when the processing software, which is hard to predict the capacity of the generated data before the processing is executed, causes the data created as the processing result to overflow the storage area of the magnetic disk device,
A means is provided for searching all other data stored in the magnetic disk device, and for making the user confirm whether or not there is any saveable data in another storage device such as the data save storage device 31. As a result, when the storage area of another user is temporarily borrowed beyond the previously allocated personal area of the user, it is necessary to keep the storage area of the magnetic disk device empty by constantly saving data. Therefore, the period of occupying the storage area of another user can be shortened.

FIG. 5 shows each component of the computer and one pre-allocated user personal area of the second storage device 28, which is represented by a bar shape with respect to the capacity. It shows the operation of the present data management device when data overflow occurs in the area. In FIG. 5, reference numerals 24 to 31 are elements constituting a computer.

When data 32 to 36 are sequentially stored in the user's personal area as shown in FIG. 5 (m), the storage area overflows when the data 36 is stored, and the disk usage state detecting device 29 causes the overflow. To detect. When the data overflow is sent to the arithmetic unit 25 as a signal, the arithmetic unit sends a warning signal to the warning display unit 30 to warn the user of the data overflow, and at the same time, the disk usage state detecting unit 2
The data name and creation date are detected for all the data stored in the user's personal area of the user using the function of 9, and a table such as (n) is created as in the fourth embodiment of the invention. To do. The computing device 25 searches the table of (n) and warns the user that the data is saved in the data saving storage device 31 by the function of the warning display device 30 in order from the oldest created date. In this case, the data saving storage device 31 is automatically saved in the data saving storage device 31 by the function of the arithmetic unit 25 and deleted from the storage area of the second storage device 28.

With the function of the data management device as described above, when the user stores the data beyond the user's personal area which is assigned in advance, the user always stores the data like the other data saving storage device 31. Since it is required to save data to the device, the time for occupying the storage area of another user is shortened, and there is an effect that more efficient data management can be realized.

[0040]

As described above, according to the present invention, the limited storage area of the second storage device 28 is efficiently managed,
In the conventional case, the processing result is stored because the data overflow can be dealt with in advance according to the warning and the data can be temporarily stored in the second storage device 28 even if the data overflow occurs. This has the effect of minimizing the waste of the processing result waiting time caused by having to save the stored contents of the second storage device 28 to the data saving storage device 31 and then re-execute it.

When the data overflow occurs and the storage area of another user is borrowed, the execution of the processing software is restricted so that the storage area of another user is significantly occupied by one user. Therefore, it is possible to obtain the effect of not hindering the use of the data management device by other users.
