Description

  The present invention relates to an information processing apparatus that performs processing related to execution of an application, a control method thereof, a program for causing a computer to execute the control method, and a computer-readable storage medium that stores the program.

  Generally, in an information processing apparatus, when executing applications, a large number of resources (memory, disk, device, etc.) are used when executing the applications. For example, in software programming, when an application is executed, a memory area is secured as a temporary work area or data storage area, and the memory area is released again when it becomes unnecessary.

  However, if the necessary resources cannot be secured during execution of the application, the operation may be slowed down or the application may be suspended. In addition, when a plurality of applications are executed, once a resource shortage occurs, there is a possibility that a resource shortage may occur in a chain not only in the application stopped halfway but also in other running applications. In such a case, in order to restore the performance and stability of the system, it is necessary to take measures to forcibly terminate the application or restart the system.

  However, there is an apparatus (information processing apparatus) that causes a significant damage due to forced termination of an application or system restart. For example, when a work content is instructed in a lot unit consisting of a plurality of wafers as in a semiconductor exposure apparatus, if the application is forcibly terminated while a lot is being processed, some wafers in the lot must be discarded. An unforeseen situation occurs. Further, the semiconductor exposure apparatus is assumed to continue to operate for several weeks once production is started based on the production plan, and the system cannot be easily restarted. This is because when the semiconductor exposure apparatus is restarted, it is necessary to perform initialization processing and hardware adjustment processing, and during that time, other devices in the factory line must also be temporarily stopped to adjust the production amount. . In this way, if a resource shortage occurs during the execution of an application and the information processing apparatus stops halfway, the customer suffers a great deal of damage.

  Conventionally, as a technique for preventing the application from being stopped halfway due to resource shortage, for example, a technique disclosed in Patent Document 1 below has been proposed. Specifically, in Patent Document 1, when an application is started, the maximum memory usage for each application is obtained, and the application is started based on whether the sum of the maximum memory usage exceeds the total amount of memory that can be used by the entire application. Whether or not is possible is determined.

JP 2006-285871 A

  However, the information processing apparatus according to the related art described above has the following problems.

  First, since the determination is performed only with the application to be activated, for example, when one function is realized as a job by sequentially activating a plurality of applications as in a semiconductor exposure apparatus, a certain application However, if a subsequent application does not start, there is a problem that the application can be started even though the job may stop in the middle.

  Second, in order to determine whether or not activation is possible only by the sum of the maximum memory usage for each application and the total amount of memory that can be used by the entire application, for example, a plurality of components that constitute one function like a semiconductor exposure apparatus. When there is a memory shared among applications, a memory that is forgotten to be released, etc., there is a problem that it may be determined that the application can be started despite the possibility of resource shortage.

  Thirdly, when it is determined that the application cannot be started, it is left to the user to determine how to control the application after notifying the warning or error. Even though the application is closed and the application can be started, there is a problem that the process remains stopped there.

  Therefore, the present invention reduces the possibility that an application will be stopped halfway due to a resource shortage, and an information processing apparatus capable of continuing processing when the resource shortage is resolved, its control method, program, and storage The purpose is to provide a medium.

  The information processing apparatus of the present invention is an information processing apparatus that performs processing related to execution of an application, and is resource information management that holds resource information that is information related to a resource secured by the application and includes a resource amount of the resource A table, monitoring means for monitoring the application, updating the resource information management table and obtaining a maximum amount of resources used for each application, resource information of the resource information management table, and the application for each application Control of execution of the application based on the calculation unit for calculating the available resource amount based on the maximum used resource amount, and the available resource amount and the maximum used resource amount in the execution target application Control means and A.

  The computer-readable storage medium of the present invention stores the program.

  According to the present invention, it is possible to reduce the possibility that an application will be stopped halfway due to resource shortage, and it is possible to continue processing when the resource shortage is resolved.

The best mode for carrying out the present invention will be described below with reference to the drawings.
In the following embodiments of the present invention, an example in which a semiconductor exposure apparatus is applied as an information processing apparatus according to the present invention will be described.

(First embodiment)
First, a first embodiment of the present invention will be described.
FIG. 1 is a block diagram showing an example of a schematic configuration of an information processing apparatus (semiconductor exposure apparatus) according to the first embodiment of the present invention. As described above, a semiconductor exposure apparatus is applied as the information processing apparatus according to this embodiment.

  As shown in FIG. 1, an information processing apparatus (semiconductor exposure apparatus) 100 includes an application group 110, a resource group 120, an application management unit 130, and a main application 140 (semiconductor exposure apparatus). Yes. The application management unit 130 includes an application control unit 134 including an application monitoring unit 131, a resource information management table 132, a resource amount calculation unit 133, and an application end detection unit 1341.

  The application group 110 includes applications being executed or waiting for execution on the target device, and is divided into a running application 111 and an execution waiting application 112, respectively.

  The resource group 120 is a collection of resources on the target device, and a memory, a disk, a device, or the like is applied to this resource.

  The application monitoring unit 131 monitors the securing and releasing of resources related to the execution of applications in the application group 110, and records and updates the resource information related to the resources in the resource information management table 132. In addition, the application monitoring unit 131 performs processing for obtaining the maximum amount of resources used for each application. At this time, the application monitoring unit 131 may obtain the maximum use resource amount by obtaining the maximum use resource amount by itself, or may cause the resource amount calculation unit 133 to obtain the maximum use resource amount and the maximum use resource amount. A resource amount may be obtained.

  In the resource information management table 132, information (resource information) obtained by the application monitoring unit 131 or the like is recorded and managed as a table.

FIG. 2 is a schematic diagram showing an example of a table of information recorded in the resource information management table 132 shown in FIG. 1 and obtained by the application monitoring unit 131 shown in FIG.
As information illustrated in FIG. 2, information on an application ID, a resource type, a system resource ID, and a resource amount related to an application of the application group 110 is set in association with the application.

  The resource amount calculation unit 133 calculates an available resource amount based on the resource information recorded (held) in the resource information management table 132 and the maximum used resource amount for each application. The resource amount calculation unit 133 performs various resource amount calculation processes including the maximum used resource amount for each application when requested by the application monitoring unit 131. Furthermore, the resource amount calculation unit 133 performs various resource amount calculation processes when requested by the application control unit 134 as necessary.

  The application control unit 134 receives an execution request for the execution waiting application 112 from the main application 140 of the semiconductor exposure apparatus, and controls the application group 110 based on the calculation result calculated by the resource amount calculation unit 133.

  Here, an application refers to a program group for realizing one function in the information processing apparatus 100, and is independent of operating system execution switching, that is, a task, thread, or process that is a scheduling unit. It is. That is, one application may be realized by a single task or multitask. At this time, information indicating which task each application is composed of is held by, for example, an operating system (not shown) of the information processing apparatus 100. Information about which application is being executed in the information processing apparatus 100 is also held by the operating system or the like. Further, a plurality of the same applications can be executed simultaneously.

  Note that in the semiconductor exposure apparatus according to the present embodiment, processing is performed by executing, as a job, a recipe that describes the processing procedure of exposure processing in advance. When the job is executed, the semiconductor exposure apparatus according to the present embodiment sequentially activates applications corresponding to the processing procedure, and realizes one function as a whole while exchanging information between the applications. At this time, the main application 140 allocates a unique execution ID for each execution job and manages the status of each job.

FIG. 3 is a schematic diagram showing an example of a recipe describing a processing procedure and exposure parameters in the information processing apparatus used in the information processing apparatus (semiconductor exposure apparatus) according to the first embodiment of the present invention.
In the recipe shown in FIG. 3, an execution ID, job name, recipe ID, reticle ID, number of wafers, apparatus state variable A, and apparatus state variable B are set in advance for each recipe.

FIG. 4 is a schematic diagram showing an example of a table for managing jobs in the information processing apparatus used in the information processing apparatus (semiconductor exposure apparatus) according to the first embodiment of the present invention.
In the job management table shown in FIG. 4, recipe ID, process 1, process 2,..., Parameter A, parameter B,. For example, as shown in FIG. 4, the job status is a table for managing recipes and device status variable values corresponding to the execution IDs shown in FIG.

  At this time, it is determined whether the application can be activated, including the activation of the subsequent application, by managing the job based on the execution ID, not the individual application in the job as a target to be managed by the information processing apparatus. Can do. As a result, it is possible to prevent an intermediate stop as a job due to a lack of application resources, and to prevent a system down or an application intermediate stop.

Next, a processing procedure of application monitoring processing in the present embodiment will be described.
FIG. 5 is a flowchart showing an example of a procedure of application monitoring processing by the information processing apparatus (semiconductor exposure apparatus) according to the first embodiment of the present invention. The processing shown in FIG. 5 is mainly performed by the application monitoring unit 131. Further, the processing shown in FIG. 5 is started each time an application of the application group 110 secures or releases resources.

  In step S101 of FIG. 5, the application monitoring unit 131 determines whether the monitoring target application has acquired (secured) resources.

If the result of determination in step S101 is that the monitored application has acquired (secured) resources, the process proceeds to step S102.
In step S102, the application monitoring unit 131 receives information such as the application name, application ID, resource type, system resource ID, and resource amount from the application that has acquired (secured) the resource.

  Here, the system resource ID becomes a return value of the system call when the resource group 120 is secured by executing the system call provided by the operating system. The return value of this system call is a value corresponding to a file descriptor in the case of a file, a start address of a reserved area in the case of a memory, and the like.

  Further, the resource amount here is the amount of resources secured at one time. For example, when a memory or the like is secured, a plurality of addresses can be secured together as one block at a time, and the number of bytes of the secured memory can be considered as the resource amount in this case.

  The application name represents the type of application, and an actual program name or the like can be considered and managed by the operating system. When managing a job as a management target, a job name managed by the main application 140 of the semiconductor exposure apparatus may be used as an application name for the job being executed.

  The application ID is uniquely assigned by the operating system to the application being executed. When a plurality of the same applications are activated, different values are assigned. At this time, the application names are the same. It is assumed that an application ID that has been used once and exists in the resource information management table 132 is not reused. If it cannot be guaranteed that the application will not be reused, the application ID of the terminated application must be managed when the application is terminated. Further, when managing a job as a management target, an execution ID that is uniquely assigned to the job being executed by the main application 140 of the semiconductor exposure apparatus may be used as the application ID.

  Subsequently, in step S103, the application monitoring unit 131 performs processing for adding the information (resource information) received in step S102 to the resource information management table 132 and holding it. As shown in FIG. 2, the resource information management table 132 is only required to be able to manage information on the resource type, system resource ID, and resource amount in association with the application ID, and the format is not particularly limited.

  Subsequently, in step S104, the application monitoring unit 131 performs a process for updating the used resource amount based on the application ID of the resource information received in step S102. Specifically, the application monitoring unit 131 obtains the currently used resource amount of the application that has secured the resource based on the application ID, obtains the sum with the resource amount received in step S102, and newly obtains this. Update as used resource amount. The amount of resources used at this time is the amount of resources currently used by the application, more precisely, the amount of resources that have been secured but not released.

  FIG. 6 is a schematic diagram showing an example of a table that holds the used resource amount for each application ID used in the information processing apparatus (semiconductor exposure apparatus) according to the first embodiment of the present invention. The table shown in FIG. 6 is held in the resource information management table 132, for example. For example, as shown in FIG. 6, the used resource amount updated in step S104 may be managed in a table for each application ID, or may be obtained each time from the table shown in FIG. At this time, the format for managing the table is not particularly limited.

  Subsequently, in step S105, the application monitoring unit 131 first performs processing for obtaining the maximum used resource amount of the application based on the application name information received in step S102. Here, the maximum used resource amount is a value when the used resource amount of the application is the largest. Even when a plurality of the same applications are activated, the maximum amount of resources used by the applications is made equal. This is because each application may increase resources up to the maximum amount of resources used.

  FIG. 7 is a schematic diagram showing an example of a table that holds the maximum use resource amount for each application, which is used in the information processing apparatus (semiconductor exposure apparatus) according to the first embodiment of the present invention. The table shown in FIG. 7 is held in the resource information management table 132, for example. Further, the maximum used resource amount shown in FIG. 7 is not particularly limited as long as the maximum used resource amount can be managed for each application name as shown in FIG. 7, for example.

  Further, in step S105, the application monitoring unit 131 determines whether or not the used resource amount updated in step S104 exceeds (exceeds) the maximum used resource amount of the application.

As a result of the determination in step S105, if the used resource amount updated in step S104 exceeds (exceeds) the maximum used resource amount of the application, the process proceeds to step S106.
In step S106, the application monitoring unit 131 performs a process of updating the maximum used resource amount of the application obtained in step S105 with the used resource amount updated in step S104. Thereafter, the processing of the flowchart shown in FIG.

  Also, as a result of the determination in step S105, if the used resource amount updated in step S104 does not exceed (does not exceed) the maximum used resource amount of the application, the processing of the flowchart shown in FIG.

If it is determined in step S101 that the application to be monitored has not acquired (secured) resources, the process proceeds to step S107.
In step S107, the application monitoring unit 131 determines whether the monitoring target application has released resources.

As a result of the determination in step S107, when the monitored application releases the resource, the process proceeds to step S108.
In step S108, the application monitoring unit 131 performs resource release processing for releasing resources. Thereafter, the processing of the flowchart shown in FIG.

  If it is determined in step S107 that the application to be monitored has not released resources, the process of the flowchart shown in FIG. 5 is terminated.

  The processing of the flowchart shown in FIG. 5 is established even when a plurality of the same applications are activated simultaneously. In this case, calculate the resource usage for each running application, compare them with the only maximum resource usage of the application, and if the usage resource exceeds the maximum usage resource, the only maximum of the application. What is necessary is just to use resource amount.

Next, a detailed processing procedure in the resource releasing process in step S108 shown in FIG. 5 will be described.
FIG. 8 is a flowchart showing an example of a detailed processing procedure in the resource release processing in step S108 shown in FIG.

  First, in step S1081, the application monitoring unit 131 receives information such as an application name, an application ID, a resource type, and a system resource ID from an application that has released a resource.

  Subsequently, in step S1082, the application monitoring unit 131 searches information (FIG. 2) in the resource information management table 132 based on the information received in step S1081, and deletes the corresponding resource information. At this time, information related to the resource amount of the corresponding resource information is temporarily stored as an open resource amount.

  Subsequently, in step S1083, the application monitoring unit 131 performs processing for obtaining a difference between the used resource amount of the application and the released resource amount stored in step S1082, based on the application ID received in step S1081. At this time, the calculation of the difference between the used resource amount of the application and the released resource amount stored in step S1082 may be performed by the resource amount calculating unit 133. Then, the application monitoring unit 131 performs a process of updating the difference between the used resource amount and the released resource amount of the obtained application as a new used resource amount.

  Through the processes in steps S1081 to S1083, the resource release process in step S108 shown in FIG. 5 is performed.

Next, a processing procedure of application control processing in the present embodiment will be described.
FIG. 9 is a flowchart showing an example of a processing procedure of application control processing by the information processing apparatus (semiconductor exposure apparatus) according to the first embodiment of the present invention. The processing shown in FIG. 9 is mainly performed by the application control unit 134.

  First, in step S201, the application control unit 134 receives an application ID of an application to be executed from the main application 140 of the semiconductor exposure apparatus.

  Subsequently, in step S202, the application control unit 134 acquires the application name of the application to be executed based on the application ID received in step S201. Then, for example, the application control unit 134 controls the resource amount calculation unit 133 to perform processing for obtaining the maximum used resource amount based on the acquired application name.

  Subsequently, in step S203, the application control unit 134 causes the resource amount calculation unit 133, for example, to perform a process for calculating an available resource amount. Here, a detailed processing procedure in the calculation process of the available resource amount in step S203 will be described using the flowchart of FIG.

  FIG. 10 is a flowchart illustrating an example of a detailed processing procedure in the calculation process of the available resource amount in step S203 illustrated in FIG. 9 according to the first embodiment of this invention.

  First, in step S2031, the application control unit 134 performs processing for acquiring application IDs of all the running applications 111.

  Subsequently, in step S2032, the application control unit 134 controls the resource amount calculation unit 133, for example, to obtain a remaining used resource amount. Specifically, for example, the resource amount calculation unit 133 has a resource having an application ID different from the application ID of the running application 111 acquired in step S2031 among the resource information (FIG. 2) existing in the resource information management table 132. The information resource amount is summed as the resource amount of the terminated application to calculate the remaining used resource amount. This is because there is a possibility that there may be a resource that is shared between applications that constitute a job or a resource that has been forgotten to be released even when the job is completed.

  Subsequently, steps S2033 to S2035 form a loop in which processing for each running application is performed on all running applications.

  In step S2034, the application control unit 134 controls the resource amount calculation unit 133, for example, and performs control for obtaining the maximum used resource amount based on the application name of the application 111 being executed. This takes into account that each application may increase resources up to the maximum amount of resources used.

  Then, when the process of step S2034 is performed for all the running applications 111, the process proceeds to step S2036.

  In step S2036, the application control unit 134 controls the resource amount calculation unit 133, for example, and performs a process of summing up the values of the maximum used resource amounts of all the running applications 111 obtained in step S2034. Then, for example, the application control unit 134 controls the resource amount calculation unit 133 to perform a process of obtaining the sum of the value obtained by the total and the remaining used resource amount obtained in step S2032 as the total maximum used resource amount. Do.

  Subsequently, in step S2037, the application control unit 134 controls the resource amount calculation unit 133, for example, to obtain a difference between the predetermined allowable amount and the total maximum used resource amount obtained in step S2036, and can use this. Resource amount. Here, the predetermined allowable amount may be a value obtained by subtracting the amount of resources used in the operating system based on the amount of physical resources.

  Through the processes in steps S2031 to S2037 described above, the available resource amount calculation process in step S203 shown in FIG. 9 is performed. This makes it possible to accurately obtain available resources even when there are resources shared among a plurality of applications, open-forget resources, and the like.

Here, the description returns to FIG. 9 again.
When the process of step S203 ends, the process proceeds to step S204.
In step S204, the application control unit 134 determines whether the available resource amount calculated in step S203 exceeds (exceeds) the maximum used resource amount of the application to be executed acquired in step S202. Judge whether or not.

As a result of the determination in step S204, if the available resource amount calculated in step S203 exceeds (exceeds) the maximum used resource amount of the application to be executed acquired in step S202, the process proceeds to step S205. move on.
In step S205, the application control unit 134 determines that a resource required for execution can be secured based on the determination in step S204, and performs control to start the application to be executed. Then, the process of the flowchart shown in FIG.

On the other hand, as a result of the determination in step S204, if the available resource amount calculated in step S203 does not exceed (does not exceed) the maximum use resource amount of the application to be executed acquired in step S202, step The process proceeds to S206.
In step S206, the application control unit 134 determines that a resource required for execution cannot be secured based on the determination in step S204, and performs application control processing. Then, the process of the flowchart shown in FIG. Here, with reference to FIGS. 11 to 14, a detailed processing procedure in the calculation process of the available resource amount in step S203 will be described.

  FIG. 11 is a flowchart illustrating an example of a detailed processing procedure in the application control processing in step S206 illustrated in FIG. 9 according to the first embodiment of this invention. The flowchart shown in FIG. 11 shows application control processing when a warning or error is notified.

  In this case, in step S20611, the application control unit 134 performs a process of notifying a warning or an error that a resource necessary for executing the execution target application cannot be secured as an application control process. Then, the process of the flowchart shown in FIG. 11 is complete | finished.

  FIG. 12 is a flowchart illustrating an example of a detailed processing procedure in the application control process in step S206 illustrated in FIG. 9 according to the first embodiment of this invention. The flowchart shown in FIG. 12 is application control processing when re-determination is performed on another execution-waiting application 112.

  First, in step S20621, the application control unit 134 determines whether there is another (one) execution-waiting application 112.

As a result of the determination in step S20621, if another execution waiting application 112 exists, the process proceeds to step S20622.
In step S20622, the application control unit 134 determines whether the available resource amount calculated in step S203 exceeds (exceeds) the maximum use resource amount of the execution waiting application 112 determined in step S20621. Judging.

  As a result of the determination in step S20622, when the available resource amount calculated in step S203 does not exceed the maximum use resource amount of the execution waiting application 112 determined in step S20621, the process returns to step S20621.

On the other hand, as a result of the determination in step S20622, when the available resource amount calculated in step S203 exceeds the maximum use resource amount of the execution waiting application 112 determined in step S20621, the process proceeds to step S20623.
In step S20623, the application control unit 134 controls application presentation or selection execution. At this time, the form of performing the selection execution may be the execution according to the selection instruction of the user, or may be automatically selected and executed. In addition, when selecting automatically, for example, a method of executing the first one found can be considered.

  When the process of step S20623 ends, or when it is determined in step S20621 that there is no other execution waiting application 112, the process of the flowchart shown in FIG. 12 ends.

  With the above processing, it is possible to avoid a problem that, even though there is an execution waiting application 112 that can be executed with the current resource amount, it becomes impossible to start all the execution waiting applications 112.

  FIG. 13 is a flowchart illustrating an example of a detailed processing procedure in the application control process in step S206 illustrated in FIG. 9 according to the first embodiment of this invention. The flowchart shown in FIG. 13 is application control processing when releasing the remaining used resources.

  First, in step S20631, the application control unit 134 determines whether there is a remaining used resource amount.

If it is determined in step S20631 that there is a remaining used resource amount, the process proceeds to step S20632.
In step S20632, the application control unit 134 performs a process of releasing the remaining used resources. In this step S20632, specifically, for example, the application group 110 is controlled based on the resource information (FIG. 2) of the resource information management table 132, and the remaining used resources are released.

  Subsequently, in step S20633, the application control unit 134 causes the resource amount calculation unit 133, for example, to perform a process for calculating an available resource amount. The calculation process of the available resource amount in step S20633 is the same as that in step S203 in FIG.

  Subsequently, in step S20634, the application control unit 134 determines whether the available resource amount calculated in step S20633 exceeds the maximum use resource amount of the execution waiting application 112 determined in step S20621.

  As a result of the determination in step S20634, if the available resource amount calculated in step S20633 does not exceed the maximum used resource amount of the execution waiting application 112 determined in step S20621, the process returns to step S20631.

On the other hand, as a result of the determination in step S20634, if the available resource amount calculated in step S20633 exceeds the maximum used resource amount of the execution waiting application 112 determined in step S20621, the process proceeds to step S20635.
In step S20635, the application control unit 134 executes the application.

  When the process of step S20635 is completed, or when it is determined in step S20631 that there is no remaining used resource amount, the process of the flowchart shown in FIG. 13 is ended.

  In the process of releasing the remaining used resources in the flowchart shown in FIG. 13, it is considered that there is a high possibility that the existing resource is a forgotten release resource even though the job is finished, and so on. . In this way, resources can be efficiently used by actively releasing resources that are not likely to be used. In addition, it is possible to avoid a problem such that an application cannot be started due to a shortage of resources even though there are unused resources.

  FIG. 14 is a flowchart illustrating an example of a detailed processing procedure in the application control process in step S206 illustrated in FIG. 9 according to the first embodiment of this invention. The flowchart shown in FIG. 14 is application control processing when waiting for an application to be executed until the running application 111 ends.

  First, in step S20641, the application control unit 134 determines whether there is a currently executing application 111 being executed.

As a result of the determination in step S20641, if there is a currently executing application 111 being executed, the process proceeds to step S20642.
In step S20642, the application control unit 134 performs a process for waiting for termination of the running application 111. In step S20642, specifically, the application end detection unit 1341 waits for at least one of the running applications 111 to end.

  Thereafter, the processes of steps S20643 to S20645 are performed. Since these processes are basically the same as the processes of steps S20633 to S20635 of FIG. 13 described above, description thereof will be omitted.

As described above, the semiconductor exposure apparatus is also applied as the information processing apparatus according to the present embodiment.

  17 is different from the configuration of the information processing apparatus (semiconductor exposure apparatus) 100 shown in FIG. 1 in that the execution target unit is changed from an application to a job. Yes, the gist is the same. At this time, a series of applications is defined as a job.

  Specifically, the application group 110 shown in FIG. 1 corresponds to the job group 210 shown in FIG. 17, and the running application 111 and the execution waiting application 112 shown in FIG. This corresponds to the execution waiting job 212. Further, the resource group 120 shown in FIG. 1 corresponds to the resource group 220 shown in FIG. 17, and the main application 140 shown in FIG. 1 corresponds to the main program 240 shown in FIG.

  Further, the application management unit 130 shown in FIG. 1 corresponds to the job management unit 230 shown in FIG. Specifically, the application monitoring unit 131 illustrated in FIG. 1 corresponds to the job monitoring unit 231 illustrated in FIG. 17, and the resource information management table 132 illustrated in FIG. 1 corresponds to the resource information management table 232 illustrated in FIG. Further, the resource amount calculation unit 133 illustrated in FIG. 1 corresponds to the resource amount calculation unit 233 illustrated in FIG. 17, and the application control unit 134 illustrated in FIG. 1 corresponds to the job control unit 234 illustrated in FIG. Further, the application end detection unit 1341 shown in FIG. 1 corresponds to the job end detection unit 2341 shown in FIG.

To do.

  In the present embodiment, a checkpoint passage detection unit 2311 is provided in the job monitoring unit 231 shown corresponding to the application monitoring unit 131 shown in FIG. The checkpoint passage detection unit 2311 is means for detecting that the job 211 being executed has passed the checkpoint.

  Here, a checkpoint refers to an event whose order is guaranteed that always occurs when a job transitions in a typical sequence. This event may be message communication or the start or end of a certain process. In addition, providing a checkpoint in a conditional branch is not desirable because it may not pass the checkpoint.

  In this semiconductor exposure apparatus, when a job is managed as a management target, each application in the job is sequentially activated and terminated for each exposure processing procedure, so a checkpoint is provided each time each application in the job is terminated. Shall.

  FIG. 18 is a schematic diagram showing an example of a table that is used in the information processing apparatus (semiconductor exposure apparatus) according to the second embodiment of the present invention to provide a checkpoint for each application and hold the maximum use resource amount. The table shown in FIG. 18 is held in the resource information management table 232, for example. For example, as shown in FIG. 18, the table shown in FIG. 18 only needs to be able to manage the order of checkpoints, checkpoint names, the maximum amount of resources used between checkpoints, etc. for each job name. It is not limited.

Next, a job monitoring process procedure according to the present embodiment will be described.
FIG. 19 is a flowchart illustrating an example of a job monitoring process performed by the information processing apparatus (semiconductor exposure apparatus) according to the second embodiment of the present invention. The processing shown in FIG. 19 is mainly performed by the job monitoring unit 231. The process shown in FIG. 19 is a process for monitoring a job when a checkpoint is provided for the job, and each application in the job secures, releases, or passes a checkpoint. It is started every time.

  In step S301 in FIG. 19, the job monitoring unit 231 determines whether an application in the job to be monitored has acquired (secured) a resource.

As a result of the determination in step S301, if the application in the job to be monitored acquires (reserves) resources, the process proceeds to step S302.
In step S202, the job monitoring unit 231 receives information on a job name, an execution ID, a resource type, a system resource ID, and a resource amount from an application that has acquired (secured) resources or a job in the application. Further, the job monitoring unit 231 receives information such as an application name and an application ID as necessary.

  Subsequently, in step S303, the job monitoring unit 231 performs processing for adding the information (resource information) received in step S102 to the resource information management table 232 and holding it.

  Subsequently, in step S304, the job monitoring unit 231 performs processing for updating the used resource amount based on the information received in step S102. The processing in step S304 is basically the same processing (processing that associates an application with a job) as the processing in step S104 shown in FIG. 5 in the first embodiment, and thus the description thereof is omitted. .

  Subsequently, in step S305, the job monitoring unit 231 first obtains the number of checkpoints passed based on the execution ID received in step S302. In step S305, the job monitoring unit 231 obtains the maximum amount of resources used for the checkpoint of the job from the number of checkpoints passed and the job name received in step S302. In step S305, the job monitoring unit 231 determines whether the used resource amount updated in step S304 exceeds (exceeds) the maximum used resource amount of the checkpoint.

FIG. 20 is a schematic diagram showing an example of a table used for an information processing apparatus (semiconductor exposure apparatus) according to the second embodiment of the present invention, which holds the scheduled maximum use resource amount and the number of passing checkpoints for each application. is there.
The table shown in FIG. 20 is held in the resource information management table 232, for example. For example, as shown in FIG. 20, the number of checkpoints passed in step S305 is not particularly limited as long as the number of checkpoints passed in association with the execution ID can be managed.

As a result of the determination in step S305, when the used resource amount updated in step S304 exceeds (exceeds) the maximum used resource amount of the checkpoint, the process proceeds to step S306.
In step S306, the job monitoring unit 231 performs processing for updating the maximum used resource amount of the checkpoint obtained in step S305 with the used resource amount updated in step S304. Then, the process of the flowchart shown in FIG.

If it is determined in step S301 that the application in the job to be monitored has not acquired (secured) resources, the process proceeds to step S307.
In step S307, the job monitoring unit 231 determines whether the application in the job to be monitored has released resources.

If the result of determination in step S307 is that the application in the monitored job has released resources, the process proceeds to step S308.
In step S308, the job monitoring unit 231 performs resource release processing for releasing resources. The processing in step S308 is basically the same processing (processing in which an application is associated with a job) as the processing in step S108 shown in FIG. 5 in the first embodiment, and a description thereof will be omitted. . Then, the process of the flowchart shown in FIG.

As a result of the determination in step S307, if the application in the job to be monitored has not released resources, the process proceeds to step S309.
In step S309, the job monitoring unit 231 determines whether an application in the job to be monitored has passed the checkpoint.

As a result of the determination in step S309, if the application in the job to be monitored has passed the checkpoint, the process proceeds to step S310.
In step S310, the job monitoring unit 231 receives execution ID and job name information from the job that has passed the checkpoint.

  Subsequently, in step S311, the job monitoring unit 231 obtains the number of check points that have passed based on the execution ID received in step S310, and updates it by one.

  In step S312, the job monitoring unit 231 refers to the checkpoint scheduled to pass based on the number of checkpoints updated in step S311 and the job name received in step S310.

  Subsequently, in step S313, the job monitoring unit 231 performs a process of updating the scheduled maximum used resource amount of the job with the maximum used resource amount among the check points scheduled to pass obtained in step S312.

Here, the planned maximum use resource amount is the maximum of the resource amount that the job can take ahead. Specifically, this will be described below.
First, the job is divided into a plurality of check points, and the maximum value of the resource amount between each check point is recorded. Next, each time the job passes the checkpoint, the scheduled maximum used resource amount is updated. This is the largest amount of resources that can be taken ahead by selecting the one with the largest maximum amount of resources from the checkpoints that have not yet passed. Further, even when a plurality of the same jobs are activated, the maximum amount of resources used until the job checkpoint is made equal. This is because each job may increase resources up to the maximum amount of resources used between checkpoints until each job passes through the checkpoint. The number of checkpoints that have passed and the planned maximum resource usage amount are, for example, as shown in FIG. The format and the like are not particularly limited as long as the planned maximum use resource amount and the number of checkpoints passed can be managed for each execution ID.

  When the process of step S313 is completed, or when it is determined in step S309 that the application in the job to be monitored has not passed the checkpoint, the process of the flowchart shown in FIG.

  The process of the flowchart shown in FIG. 19 is established even when a plurality of the same jobs are activated simultaneously. In this case, the used resource amount is obtained for each activated job, and is compared with the only maximum used resource amount at the checkpoint of the job. Then, when the used resource amount exceeds the maximum used resource amount of the checkpoint, the only maximum used resource amount at the checkpoint of the job may be set.

  The job control process by the job control unit 234 in the second embodiment is basically the same as the process in FIG. 2 in the first embodiment (a process in which an application is associated with a job). . Here, with reference to FIG. 21, the calculation process of the available resource amount shown in step S203 of FIG. 2 when a checkpoint is provided will be described.

  FIG. 21 is a flowchart illustrating an example of a detailed processing procedure in the calculation process of the available resource amount performed by the control of the job control unit 234 illustrated in FIG. 17 according to the second embodiment of this invention.

  Here, the processing of the flowchart of FIG. 21 is basically the same processing (processing that associates an application with a job) as the processing of the flowchart shown in FIG. 10 in the first embodiment. That is, the process of the flowchart of FIG. 21 corresponds to the detailed process of the process in step S203 of FIG. 2 corresponding to the present embodiment.

First, in step S <b> 401, the job control unit 234 performs processing for acquiring execution IDs of all running jobs 211.

  Subsequently, in step S <b> 402, the job control unit 234 performs control to determine the remaining used resource amount by controlling the resource amount calculation unit 233, for example. The processing in step S402 is basically the same processing (processing in which an application is associated with a job) as the processing in step S2032 shown in FIG. 10 in the first embodiment, and the detailed description thereof is as follows. Omitted.

  Subsequently, steps S403 to S405 form a loop in which processing for each job being executed is performed for all the jobs being executed.

  In step S <b> 404, the job control unit 234 controls the resource amount calculation unit 233, for example, and performs control for obtaining the scheduled maximum used resource amount based on the execution ID of the job 211 being executed. This takes into account that each job may increase resources up to the planned maximum used resource amount.

  When the process of step S404 is performed for all the running jobs 211, the process proceeds to step S406.

  In step S406, the job control unit 234 controls the resource amount calculation unit 233, for example, and performs a process of summing the values of the scheduled maximum used resource amounts of all the running jobs 211 obtained in step S404. Then, for example, the job control unit 234 controls the resource amount calculation unit 233 to perform processing for obtaining the sum of the total value and the remaining used resource amount obtained in step S402 as the total maximum used resource amount.

  Subsequently, in step S407, the job control unit 234, for example, controls the resource amount calculation unit 233 to obtain a difference between the predetermined allowable amount and the total maximum used resource amount obtained in step S406, and can use this. Resource amount. Then, the process of FIG. 21 is complete | finished.

  Next, with reference to FIG. 22, a description will be given of job control processing when waiting for a job to be executed until the running job 211 passes a checkpoint.

  FIG. 22 is a flowchart illustrating an example of a processing procedure of job control processing performed by the job control unit 234 illustrated in FIG. 17 according to the second embodiment of this invention.

  Here, the processing of the flowchart of FIG. 22 is basically the same processing as the processing of the flowchart shown in FIG. 14 in the first embodiment (processing in which an application is associated with a job). That is, the process of the flowchart of FIG. 22 corresponds to the detailed process of the process in step S206 of FIG. 2 corresponding to the present embodiment.

  First, in step S501, the job control unit 234 determines whether there is a currently executing job 211 being executed.

As a result of the determination in step S501, if there is a currently executing job 211 being executed, the process proceeds to step S502.
In step S502, the job control unit 234 waits for notification from the checkpoint passage detection unit 2311 that at least one running job 211 has passed the checkpoint. As a result, it is possible to more efficiently determine whether the resource shortage has been resolved, so that it is possible to further avoid the problem that the job is not started even though the resource shortage has been resolved. .

  Thereafter, the processes of steps S503 to S505 are performed, and the process of the flowchart of FIG. 22 ends. The processing in steps S503 to S505 is basically the same processing (processing in which an application is associated with a job) as the processing in steps S20643 to S20645 shown in FIG. 14 in the first embodiment. Detailed description is omitted.

  As described above, according to the present embodiment, it is possible to accurately obtain the amount of resources that may be used according to the progress of job processing by providing checkpoints in the job (for example, see FIG. 15). . In other words, if a job uses a large amount of resources at the beginning and uses almost no resources from a certain point in time to the end, the amount of resources to be estimated can be reduced by passing through a certain point in time, and the amount of resources can be made more accurate. Can be estimated. As a result, it is possible to avoid a problem that a new job cannot be activated even though there are sufficient resources.
