Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an information processing device, and more particularly, to an information processing device that is equipped with a plurality of input/output processing devices and a memory processing device that can operate simultaneously, and that performs predetermined data processing involving file access. The present invention relates to an information processing apparatus that performs the predetermined data processing by dividing into a plurality of input/output processing and memory processing that can be executed simultaneously, and dividing them into one input/output processing device and one memory processing device.

[Conventional technology]

Conventionally, in this type of information processing device, when performing predetermined data processing such as conditional search or classification on a large number of files, the data processing is divided into multiple input/output processes that can operate simultaneously. Each input/output processing device is assigned to perform parallel processing, and memory processing for data related to input/output processing of each input/output processing device is divided into a predetermined number of memory processes that can be executed simultaneously. The data processing speed has been increased by dividing the memory processing into one memory processing device and performing parallel processing.

[Problem to be solved by the invention]

According to the conventional information processing device described above, one data process is divided into multiple input/output processes and memory processing, and these are processed in parallel, so a single input/output process is performed without such division. Faster processing is possible than when data processing is performed using an output processing device and a memory processing device.

However, in conventional information processing devices, the memory processing for data related to the input/output processing of each input/output processing device is divided into a predetermined number of memory processings that can be executed simultaneously, resulting in the following problems. there were.

(]) If the input/output processing time by the input/output processing device is longer than the memory processing time by the memory processing device, the memory processing is divided into a predetermined number of memory processings that can operate simultaneously, and each memory processing device is processed by one memory processing device. Even if the processing is divided, the input/output processing time becomes a bottleneck, and the overall processing time cannot be shortened, which is disadvantageous due to the use of a large number of memory processing devices.

(2) If the input/output processing time by the input/output processing device is shorter than the memory processing time by the memory processing device, the idle time for input/output processing can be shortened by further increasing the number of memory processing operations that are performed simultaneously. In this case, the data processing time can be further reduced, but since the number of memory processing divisions is fixed, such a measure cannot be taken.

The present invention has been made in view of these circumstances,
The purpose is to provide an information processing device that can effectively utilize a memory processing device and reduce data processing time as much as possible.

Next, the operation of the information processing apparatus of this embodiment will be explained. As a prerequisite, one data process is divided into multiple input/output processes based on the content of the data process, and the memory processing for each input/output process is performed by two memory processes that can operate simultaneously at the time of operation start. The processing is divided into two memory processing devices, and if necessary, memory processing for individual input/output processing can be executed using up to four memory processing devices.

When an instruction to execute data processing is given, the data processing control device 1 divides the input/output processing involved in the data processing into a plurality of input/output processing devices that can operate simultaneously, and one input/output processing device 21 . 22. 23, . . . and one memory processing device 11, 12, 13, . ...is executed. Figure 2 shows a time chart when the ratio of memory processing time to input/output processing time is 1:2;
In the case of the present invention, the number of memory processing divisions in the same figure (g) is 2.
This is the case of the conventional method where it is fixed at . This second figure (
The first part of the time chart a) shows a part of the situation at the beginning of data processing according to the present invention, in which one input/output process is executed in the input/output processing device 21, and the data related to the input/output process is Memory processing is executed in two memory processing bags, fill, 12.

When data processing is executed, the time monitoring device 2 monitors each input/output processing device 21, 22, 23 . ... and the memory processing time required for each input/output process, and notify the data processing control device 1 of the monitoring results. As a result, in the case of Fig. 2(a), the time for one input/output process is (1, -1,), and the memory processing time for data for one input/output is 2(tt t −+”) are obtained by the time monitoring device 2 and notified to the data processing control device 1. Then, assuming that the input/output processing time of the input/output processing device 21 is the longest, the data processing control bag fit is [ Tm/Ti]”
= [2(tx t+)/(t+ to
)]"-[1/2]"-1, it is determined that the memory processing of the data related to the input/output processing is performed in one memory processing, and as shown in the time chart of Fig. 2 (a). For example, only the memory processing device 11 is used to execute the memory processing.

On the other hand, in the conventional method in which the number of divisions of memory processing is fixed at 2, two memory processing units 1 (11, 12) are always used to process the data, as shown in the time chart of Q:1) in Figure 2. Processing will proceed. As can be seen by comparing Figure 2 (a) and [Yes], if the input/output processing time is longer than the memory processing time, it is recommended to divide the memory processing into multiple memory processing that can operate simultaneously. even if,
Since the input/output processing time does not change, the overall processing time hardly changes.

That is, there is almost no difference in processing time between the conventional method shown in FIG. 2(b) and the case of the present invention shown in FIG. 2(a), and the present invention uses only one memory processing device. This allows the memory processing device to be used more efficiently than in the conventional system.

On the other hand, FIG. 3 shows a time chart when the ratio of memory processing time to input/output processing time is 481, and FIG. 3(a) shows the case of the present invention, and FIG. 3(b) shows the case of the conventional method. . When there is such a relationship between input/output processing time and memory processing time, in the present invention, [T m / Ti1゛= [2(

divided into four memory processing units 11
．． 12, 13, and 14 (however, 14 is not shown in FIG. 1) are used to proceed with the process. As a result, the data processing speed is increased compared to the conventional method shown in FIG. 4(b). In this way, if the input/output processing time is shorter than the memory processing time and the idle time of the input/output processing can be shortened by further increasing the number of memory processing operations to be performed simultaneously, the present invention is better overall. It is possible to shorten the data processing time.

[Effects of the Invention] As explained above, in the information processing device of the present invention, the actual memory processing time and input/output processing time are monitored,
The number of divisions for memory processing is optimally determined according to the monitoring results, so if the input/output processing time is longer than the memory processing time, the number of divisions is reduced and resource efficiency is achieved by using only a small number of memory processing devices. Data processing can proceed with a good configuration, and conversely, if the input/output processing time is shorter than the memory processing time, the number of divisions is increased and the number of memory processing devices used is such that the data processing time is minimized. Data processing is advanced, and therefore, there is an effect that the data processing time can be shortened while making effective use of the memory processing device.
