Description

The present invention relates to an information processing device, an information processing method, and a program.

As one technique for efficiently using the main memory, it is known that the operating system performs virtual memory management.

As an example of technology for performing such virtual memory management, there is, for example, Patent Document 1. Japanese Patent Application Laid-Open No. 2002-200000 describes memory management that performs virtual memory management by referring to a page table, which is a table that associates a plurality of virtual addresses included in a virtual address space with a plurality of physical addresses included in each of a plurality of segments. A memory management system with units is described.

JP 2014-6895 A

When a new program is loaded while a job in execution is loading multiple programs, there may not be enough free space in the virtual storage space. In such a case, the free space is formed by deleting the already loaded program once.

Here, the extension of the architecture may extend the virtual storage space managed by the OS (Operating System). However, in order for existing programs to use the expanded space, modifications are required to accommodate the expanded architecture. Therefore, even if the virtual storage space managed by the OS has been expanded, the expanded space cannot be used effectively when it is not easy to modify the program. In other words, even though the virtual storage space managed by the OS has a free space, the already loaded program is once deleted.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an information processing apparatus, an information processing method, and a program that solve the problem that it is sometimes difficult to effectively use an expanded virtual storage space.

[First embodiment]
A first embodiment of the present invention will be described with reference to FIGS. 1 to 12. FIG. FIG. 1 is a block diagram showing an example of the configuration of an information processing apparatus 100. As shown in FIG. FIG. 2 is a diagram showing an example of a virtual storage space managed by an OS. FIG. 3 is a diagram showing an example of the evacuation status management table 116. As shown in FIG. 4 to 10 are diagrams showing an example of processing performed by the information processing apparatus 100. FIG. FIG. 11 is a flowchart showing an example of the flow when the information processing apparatus 100 executes unload processing. FIG. 12 is a flowchart showing an example of the flow when the information processing apparatus 100 performs load processing.

In the first embodiment of the present invention, an information processing apparatus 100 in which a virtual storage space managed by an OS 110 (Operating System) is expanded due to expansion of architecture or the like will be described. As will be described later, in the case of this embodiment, the OS 110 saves the program to be deleted from the conventional space in the virtual storage space to the extended space. The OS 110 also manages the save status of the program by updating the save status management table 116 . With such a configuration, the OS 110 can effectively utilize the extended space even in programs that do not support the extended space.

In addition, in this embodiment, the information processing apparatus 100 has the following premises. First, it is assumed that the virtual storage space is composed of segments, which are groups of logical code data. It is also assumed that the allocation of the main storage device 120 is performed in units of fixed-length pages, and that the pages constitute segments. Note that the present invention may be applied to configurations other than those exemplified in this embodiment.

The information processing apparatus 100 can execute jobs including one or more programs. The program executed by the information processing apparatus 100 may or may not support the extended space.

FIG. 1 shows an example of the configuration of an information processing apparatus 100 that is characteristic of this embodiment. Referring to FIG. 1 , an OS 110 functions in the information processing apparatus 100 . The information processing device 100 also has a main storage device 120 and a disk device 130 .

The information processing apparatus 100 has an arithmetic device such as a CPU and a storage device. For example, the information processing apparatus 100 implements the above-described OS 110 and various functions of the OS 110 by executing a program stored in a storage device by an arithmetic device.

The OS 110 has an extended virtual memory space to manage due to an extended architecture. FIG. 2 shows an example of expanded virtual storage space. As shown in FIG. 2, the OS 110 manages not only the conventional space, which is the space before expansion, but also the expanded space, which is the expanded space. Thus, in this embodiment, the OS 110 manages the extended virtual storage space.

Here, among the programs that can be executed by the information processing apparatus 100, programs that are not compatible with the extended space cannot use the extended space in the state before modification to support the extended space. Therefore, in the state before the modification, in order to load a new program when the conventional space is full, it is necessary to delete the program from the conventional space to secure the space in the conventional space. In order to be able to use the extended space, it is necessary to modify the program so that it supports the extended space. However, program modification is not always easy.

Therefore, the OS 110 described in this embodiment has a configuration for effectively utilizing the expansion space even if the program has not been modified. For example, the OS 110 has a determination unit 111, a save unit 112, a release unit 113, and a load unit 114 as a configuration for effectively utilizing the expansion space. Also, the OS 110 manages a page table 115 and an evacuation status management table 116 .

When deleting a program from the conventional space, the determining unit 111 determines whether or not to save the program to be deleted to the extended space. For example, the determination unit 111 checks the evacuation status management table 116 . Based on the information (program information) registered in the evacuation status management table 116, the determination unit 111 determines whether or not to evacuate the program to be deleted to the expansion space.

For example, when program information indicating a program to be deleted, such as a program name, is registered in the save status management table 116, the determining unit 111 determines that the program to be deleted has already been saved to the expansion space. In this case, the determination unit 111 determines not to newly save the deletion target program to the expansion space. Then, the determination unit 111 notifies the release unit 113 that the program to be deleted will not be saved in the expansion space. On the other hand, when the information indicating the program to be deleted is not registered in the save status management table 116, the determination unit 111 determines that the program to be deleted has not been saved in the extended space. In this case, the determination unit 111 determines to save the deletion target program to the expansion space. Then, the determining unit 111 notifies the saving unit 112 that the program to be deleted is to be saved in the expansion space.

Note that, in the present embodiment, the method of selecting a program to be deleted is not particularly limited. The information processing apparatus 100 (for example, the determination unit 111) can select a program to be deleted from programs loaded in the conventional space using an arbitrary method. For example, the determination unit 111 can select a program to be deleted based on the time when the program was loaded, whether the program is used, the elapsed time since the program was last used, and the like.

Further, the determination unit 111 may be configured to select a program to be deleted based on the evacuation status management table 116 . For example, when a program is registered in the evacuation status management table 116, the determination unit 111 can be configured to preferentially target the registered program for deletion. Further, for example, the determination unit 111 may be configured to delete programs that are not registered in the evacuation status management table 116 until the free space of the expansion space becomes equal to or less than a predetermined threshold value.

The determination unit 111 may be configured to select a program to be deleted by a combination of a plurality of methods described above, or a combination of the above method and a known method.

When the determining unit 111 determines to save the program to be deleted in the extended space, the saving unit 112 saves the program to be deleted. For example, the saving unit 112 secures in the expansion space the same number of segments (old segments) used in the conventional space by the program to be deleted (new segments). Then, the saving unit 112 associates the pages forming the old segment with the pages forming the new segment. This may, for example, simply copy the page table address stored in the segment descriptor from the old segment to the new segment. In this way, the saving unit 112 saves the program to be deleted in the extension space by changing only the logical address without changing the physical address in the page table 115 . After saving the program to be deleted in the expansion space, the save unit 112 notifies the release unit 113 that the save has been completed.

In addition, the saving unit 112 updates the save status management table 116 when saving the program to be deleted. For example, after saving a program to be deleted in the expansion space, the saving unit 112 registers program information (for example, program name, library name, etc.) indicating the saved program in the saving status management table 116 . Through such processing, the program information indicating the programs saved in the expansion space is registered in the save status management table 116 .

Note that the program information registered by the saving unit 112 can include a program name, a library name, and the like. The saving unit 112 may be configured to register program information including information other than the above examples.

The release unit 113 releases the program to be deleted. For example, the release unit 113 receives a notification from the determination unit 111 to the effect that the program to be deleted will not be saved in the expansion space. Alternatively, the releasing unit 113 receives a notification from the saving unit 112 that the saving has been completed. The releasing unit 113 then initializes the segment descriptor of the old segment, which is the segment used in the conventional space, and releases the old segment.

Note that the program to be deleted is previously saved in the expansion space by the processing of the saving unit 112 . Even if the release unit 113 releases the old segment, the new segment continues to remain without being released.

The loading unit 114 loads programs. For example, the loading unit 114 confirms whether or not there is an empty space in the conventional space. Then, if there is no space in the conventional space, the loading section 114 secures a space in the conventional space. For example, the loading unit 114 instructs the determination unit 111 to select a program to be deleted, so that the above-described series of processing can be performed to secure the space.

After the release unit 113 secures an empty space in the conventional space as a result of the instruction to the determination unit 111 by the loading unit 114 , or when there is an empty space in the conventional space, the loading unit 114 refers to the evacuation status management table 116 . Then, the loading unit 114 confirms whether or not the program to be loaded into the conventional space has been saved in the expansion space based on the save status management table 116 .

When program information indicating a program to be loaded is registered in the save status management table 116, the loading unit 114 determines that the program to be loaded is saved in the expansion space. Then, the loading unit 114 determines to load the load target program from the expansion space, and loads the load target program from the expansion space. Loading from extended space can be accomplished by simply copying the page table address in the segment descriptor from the extended space segment to the conventional space segment. In other words, the load unit 114 loads the program to be loaded into the conventional space by changing only the logical address without changing the physical address in the page table 115 . Thus, when the program to be loaded has been saved in the expansion space, the loading unit 114 loads the program from the expansion space instead of from the disk device 130 . Therefore, it can be loaded at high speed.

On the other hand, if program information indicating the program to be loaded is not registered in the save status management table 116, the loading unit 114 determines that the program to be loaded has not been saved to the expansion space. The load unit 114 then determines to load the program to be loaded from the library file on the disk device 130 and loads the program to be loaded from the disk device 130 . The process of loading from the library file on the disk device 130 may be the same as the conventional process.

As described above, the loading unit 114 loads the load target program from different locations depending on whether the load target program has been saved in the expansion space or not.

The page table 115 associates virtual addresses with physical addresses. The configuration of the page table 115 may be a known one.

Program information indicating programs saved in the expansion space can be registered in the save status management table 116 . FIG. 3 shows an example of the configuration of the evacuation status management table 116. As shown in FIG. Referring to FIG. 3, the save status management table 116 contains program information indicating programs saved in the save space. The program information can include, for example, the program name and library name. The program information may contain information other than those exemplified above.

As described above, the saving status management table 116 is updated when the saving unit 112 saves the program to the expansion space. Therefore, the program information saved in the expansion space is registered in the save status management table 116 .

Note that the evacuation status management table 116 is defined for each job, for example. In other words, the information processing apparatus 100 can have a different evacuation status management table for each job. The evacuation status management table may be configured so as to be common to a plurality of jobs.

The main memory device 120 is a memory that can be directly read and written by an arithmetic device such as a CPU included in the information processing device 100 . In this embodiment, the configuration of the main storage device 120 is not particularly limited.

The disk device 130 is a storage device such as a hard disk drive. The disk device 130 may be a storage device such as an SSD (Solid State Drive).

The above is an example of the configuration of the information processing apparatus 100 .

Of the virtual storage spaces, the conventional space is a space that can also be used by programs that are not compatible with the extended space. Therefore, it can be said that the conventional space is a space that can be used by programs that do not support expansion. The extended space in the virtual storage space is a space that cannot be used by programs that do not support extended space. Therefore, it can be said that the expansion space is a space that cannot be used by programs that do not support expansion.

Next, an example of processing when saving and loading a program will be described with reference to FIGS. 4 to 12. FIG.

First, an example of processing when a program is unloaded will be described with reference to FIGS. 4 to 8 and 11. FIG. A program is unloaded, for example, when a job to be executed by the information processing apparatus 100 attempts to load a new program and there is no space in the conventional space. Program unloading may be performed at any time.

The information processing apparatus 100 or the determination unit 111 selects programs to be deleted by any method. Then, as shown in FIG. 11, the determination unit 111 checks the save status management table 116 to determine whether or not to save the program to be deleted to the expansion space (step S101).

When information indicating a program to be deleted, such as a program name, is not registered in the save status management table 116 (step S101 No, 1-1 in FIG. 4), the determining unit 111 saves the program to be deleted to the expansion space. decide. Then, the determining unit 111 notifies the saving unit 112 that the program to be deleted is to be saved in the expansion space.

The saving unit 112 saves the program to be deleted (step S102, 1-2 in FIG. 5). Any method may be used to determine the save location in the expansion space. Also, the evacuation unit 112 updates the evacuation status management table 116 (step S103, 1-3 in FIG. 5). In other words, the saving unit 112 registers the program information indicating the saved program in the saving status management table 116 .

The release unit 113 deletes the program by releasing it from the conventional space (step S104, 1-4 in FIG. 6).

If information indicating a program to be deleted, such as a program name, is described in the evacuation status management table 116 (step S101 Yes, 1-1b in FIG. 7), the determination unit 111 determines whether the program to be deleted is stored in the extended space. It is judged that it has been evacuated. In this case, the processes of steps S102 and S103 are not performed, and the release unit 113 releases the program to be deleted from the conventional space, thereby deleting the program (step S104, 1-2b in FIG. 8).

The above is an example of processing when a program is unloaded. Next, an example of processing when loading a program will be described with reference to FIGS. 9, 10, and 12. FIG.

Referring to FIG. 12, the loading unit 114 confirms whether or not there is an empty space in the conventional space (step S201).

If there is no space in the conventional space (step S201 No), the loading unit 114 secures space in the conventional space. For example, the loading unit 114 instructs the determination unit 111 to select a program to be deleted, so that the space can be secured by the series of processes described with reference to FIG. 11 (step S202). A detailed description of the processing for securing an empty space in the conventional space is omitted because it has already been described with reference to FIG.

After securing space in the conventional space (after step S202), or when there is space in the conventional space (Yes in step S201), the loading unit 114 refers to the evacuation status management table 116 and loads the data into the conventional space. It is checked whether or not the target program has been saved in the expansion space (step S203).

When information indicating the program to be loaded is registered in the evacuation status management table 116 (Yes in step S203, 2-1 in FIG. 9), the loading unit 114 determines that the program to be loaded has been evacuated to the expansion space. to decide. Then, the loading unit 114 loads the program to be loaded from the expansion space (step S205, 2-2 in FIG. 9).

On the other hand, if the information indicating the program to be loaded is not registered in the save status management table 116 (No in step S203, 2-1b in FIG. 10), the loading unit 114 detects whether the program to be loaded has been saved in the expansion space. judge not. In this case, the loading unit 114 loads the program to be loaded from the library file on the disk device 130 (step S204, 2-2b in FIG. 10).

The above is an example of processing when loading a program.

As described above, the information processing apparatus 100 has the save unit 112 and the release unit 113 . With such a configuration, the releasing unit 113 can release the program to be deleted from the conventional space after the saving unit 112 has saved the program to be deleted from the conventional space to the extended space. As a result, even a program that does not support the extended space can utilize the extended space. Moreover, as a result, when loading the program saved in the expansion space, it becomes possible to load the program at high speed. In addition, it is possible to suppress I/O to the disk, and it is possible to suppress deterioration in job execution performance.

Further, the information processing apparatus 100 according to the present embodiment has a discrimination section 111 . With such a configuration, the saving unit 112 described above can save the program to the expansion space according to the determination result of the determining unit 111 . This makes it possible to efficiently save only the programs that need to be saved.

Further, the information processing apparatus 100 according to this embodiment has a loading unit 114 . With such a configuration, the loading unit 114 can load a program that can be loaded from the extension space from the extension space. As a result, high-speed loading can be realized.

Note that the information processing apparatus 100 described in the present embodiment is merely an example. The configuration of the information processing apparatus 100 is not limited to that described in this embodiment.

For example, in this embodiment, the information processing device 100 has the disk device 130 . However, the disk device 130 may be provided outside the information processing device 100 . In this embodiment, the OS 110 has each function. I don't mind. Also, each component of the information processing apparatus 100 may be implemented as a memory management apparatus that performs memory management.

FIG. 13 shows an example of the configuration of the information processing device 200. As shown in FIG. Referring to FIG. 13 , the information processing device 200 has a save section 210 and a release section 220 .

For example, the information processing device 200 has an arithmetic device such as a CPU and a storage device. The information processing apparatus 200 implements each of the processing units described above by causing the arithmetic device to execute a program stored in the storage device.

When deleting a program from the conventional space, which is the virtual storage space before expansion, the saving unit 210 saves the program to be deleted to the expansion space, which is the virtual storage space expanded from the conventional space.

The releasing unit 220 releases the program to be deleted from the conventional space after the saving by the saving unit 210 .

As described above, the information processing device 200 has the save unit 210 and the release unit 220 . With such a configuration, the releasing unit 220 can release the program to be deleted from the conventional space after the saving unit 210 has saved the program to be deleted from the conventional space to the extended space. As a result, even a program that does not support the extended space can utilize the extended space.

Further, the information processing apparatus 200 described above can be realized by installing a predetermined program in the information processing apparatus 200 . Specifically, when deleting a program from a conventional space, which is a virtual storage space before expansion, in an information processing apparatus in which a virtual storage space managed by an operating system has been expanded, a program, which is another aspect of the present invention, is deleted from the conventional space. To implement a saving unit that saves a program to be deleted in an extended space, which is a virtual storage space expanded from the space, and a releasing unit that releases the program to be deleted from the conventional space after saving by the saving unit. It's a program.

When saving the program to be deleted, it is confirmed whether the program to be deleted is saved in the extension space, and based on the confirmation result, it is decided whether to save the program to be deleted in the extension space. and, based on the determination result, save the program to be deleted in the extension space;
When the program to be deleted is not saved in the extended space at the time of the determination, it is determined to save the program to be deleted in the extended space.
Information processing methods. In an information processing device with an expanded virtual storage space managed by an operating system,
a saving unit that, when deleting a program from a conventional space that is a virtual storage space before expansion, saves the program to be deleted to an expansion space that is a virtual storage space expanded from the conventional space;
a releasing unit that releases the program to be deleted from the conventional space after being saved by the saving unit;
to realize
realizing a determination unit for confirming whether or not a program to be deleted has been saved in the extension space, and determining whether or not to save the program to be deleted in the extension space based on the confirmation result;
The saving unit saves the program to be deleted in the expansion space based on the determination result of the determining unit,
The determining unit determines to save the program to be deleted in the extended space when the program to be deleted is not saved in the extended space.
program. An information processing device in which a virtual storage space managed by an operating system is expanded,
