DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for displaying program execution status, and particularly to a method for displaying program execution status in a computer system.

[Conventional technology]

Conventionally, in this type of program execution status display method, it is difficult to determine which resource (CPU) a specified program is using.

How much time have you used the files (files, etc.) to date?

Information indicating whether the program was running (such as the number of inputs and outputs) was displayed, but there was no information indicating how long it would take for the program to finish.

For this reason, when you want to know how much time left for a program to finish, you typically use the operator.

A program executor such as Blograya or a system operator records in advance the CPU occupation time, input/output times, etc. required for the program to finish, and displays the current status displayed by inputting the program execution status display instruction command. The remaining execution time of the program (hereinafter referred to as program end time) was manually calculated and estimated by referring to the CPU occupancy time of the program, the number of outputs by five people, etc.

[Problem to be solved by the invention]

In the conventional program execution status display method described above, the specified program does not know which resource (CPU).

Although information indicating how much the file (files, etc.) has been used up to now (time, input/output count, etc.) was displayed,
Information indicating how long it would take for the program to finish was not displayed, so in order to calculate the program finish time, you had to record the usage of various resources for each program in advance and manually calculate the program finish time. However, it has the drawbacks of being troublesome and prone to errors.

In view of the above-mentioned points, an object of the present invention is to be able to display the program end time of a program being executed in response to input of a program execution state display instruction command, and to enable a program executor or system operator to display the program end time. To provide a program execution status display method that allows you to easily grasp how much time it will take for a program to finish without the trouble and calculation errors required when performing manual calculations.

[Means to solve the problem]

The program execution status display method of the present invention is a computer system that displays the status of a program being executed on a visual display device, and stores and saves the amount of various resources used by each program at the end of the program. A program information storage means receives a program execution status display instruction command for a program being executed, and the amount of usage of various resources used up to now regarding the specified program and the corresponding program convex gram stored by the program information storage means. A program end time prediction means for calculating and estimating the program end time based on the usage amount of various resources used until the end of the program; and a program end time prediction device that visually displays the program end time obtained by the program end time prediction means. and program execution status display means for displaying the program execution status.

[Effect]

In the program execution status display method of the present invention, the program information storage means stores and saves the usage amount of various resources used by the program at the end of the program for each program, and the program end time prediction means The program execution status display instruction command is received, and the usage amount of various resources used up to the present regarding the specified program and the usage amount of various resources used until the end of the program saved by the program information storage means are displayed. Based on this, the program end time is calculated and estimated, and the program execution state display means displays the program end time obtained by the program end time prediction means on a visual display device.

(Example) Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a program execution status display method according to an embodiment of the present invention.

The program execution status display method of this embodiment stores the CPU (central processing unit) occupation time used by the program and the file l10 (input/output) count for each program in the program information storage file 2 at the end of the program. a keyboard 3 for manually inputting program execution status display instruction commands for the program being executed, and CPU occupancy time used up to now regarding the program specified by the program execution status display instruction command. and file 110 times and the CPU occupation time used until the end of the program saved in program information storage file 2 and file 1
a program end time predicting means 4 that calculates and estimates the program end time based on the number of times the program ends, and a program execution state that displays the program end time obtained by the program end time predicting means 4 on a CRT (visual display device) 6; Referring to FIG. 2, the program information storage file 2 includes a program name 21. A plurality of records consisting of CPU occupation time 22 and file 110 count 23 are stored.

Next, the operation of the program execution status display method of this embodiment configured as described above will be explained.

When the executed program ends, the program information storage means 1 stores the CPU occupation time 22 used by the program.
and the file 110 count 23 are stored in the program information storage file 2.

Specifically, the program information storage means I first searches the program name 21 of the program information storage file 2 using the name of the terminated program, and if the same program name 21 does not exist, it newly stores the program name 21. A record of CPU occupation time 22 and file 110 count 23 is created and registered in the program information storage file 2. on the other hand,
Same program name 2! If so, the program information storage means 1 replaces the CPU occupation time 22 and file 110 count 23 of that record with the current data. As a result, the CPU occupation time 22 and file 110 count 23 of the completed program are registered in the program information storage file 2.

When the operator inputs the program name 21 of the program currently being executed from the keyboard 3 as a parameter of the program execution status display instruction command, the program end time prediction means 4 checks the program name 21 that has been specified for multiple purposes.

Specifically, the program end time predicting means 4 first checks whether the program with the designated program name 21 is actually the program currently being executed, and determines an error if the program is not currently being executed. Furthermore, even if the program is in execution, if a record with the program name 21 is not registered in the program information storage file 2 (in other words, if it is the first program to be executed), an error will occur. do.

Only when the program is currently being executed and a record of the corresponding program name 21 is registered in the program information storage file 2, the program end time prediction means 4 performs the process of predicting the subsequent program end time.

Specifically, the program end time prediction means 4 first calculates the elapsed time (ELAP) from the start of the program to the present time.
