The use of the information processing system 1 is not particularly limited, but it can be used, for example, as a medical image display system used in medical institutions. When the information processing system 1 is used as a medical image display system, the terminal device 50 is used as a display terminal for displaying medical images. Compressed medical image data of medical images generated by modalities not shown (for example, CT (Computed Tomography), MRI (Magnetic Resonance Imaging), DR (Digital Radiography), etc.) are stored and managed in the shared storage 20. . Then, when a medical image display request is transmitted from the terminal device 50 and accepted by the management server 40 in accordance with the user's input operation to the terminal device 50, the compressed medical image data copied to the shared cache device 30 becomes a plurality of pieces of information. Decompression processing is performed by the information processing server group 100 including the processing server 10 , and the decompressed medical image data is transmitted to the terminal device 50 and displayed on the terminal device 50 .

Next, operations of the information processing system 1 will be described.
Here, an operation for displaying an image related to the compressed image data D1 stored in the shared storage 20 on the display unit 54 of the terminal device 50 and an image display process for performing the operation will be described.

FIG. 5 is a flowchart showing a control procedure for image display processing.
In the image display process, first, the control unit 41 of the management server 40 accepts a process request for image display (step S101). Here, as shown in FIG. 6, one terminal device 50 requests one of the information processing servers 10a to 10d to execute data processing for displaying an image related to specific compressed image data D1 ( processing request) is sent. The information processing server 10 of the transmission destination here may be determined in advance by being associated with each terminal device 50, or may be selected each time according to the operating status of each information processing server 10 at the time of transmission. good. Also, the processing request is transmitted from the information processing server 10 that has received the processing request to the management server 40 .
The data processing for displaying the image related to the compressed image data D1 is decompression processing (expansion processing) of the compressed image data D1 here, but may further include predetermined image processing.

Next, the control unit 41 (scaling means) executes scaling based on the content of the received processing request, and determines the configuration of the information processing server group 100 (step S102).
Here, based on information including at least one of information related to the compressed image data D1 to be processed and information related to the operating status of the information processing servers 10a to 10d (hereinafter referred to as "reference information"), the control unit 41 scaling. More specifically, the reference information includes the number of currently available surplus information processing servers 10, the number of files and data amount of compressed image data D1 to be processed, data Information such as the amount of calculation (processing amount) required for processing and whether or not data processing requires advanced image processing (advanced calculation processing such as graphic processing) may be included.

In scaling, the control unit 41 adjusts the number of information processing servers 10 included in the information processing server group 100 based on the reference information. Moreover, the processing capacity (spec) of at least a part of the information processing servers 10 included in the information processing server group 100 is adjusted as necessary. Here, the processing capacity may include the processing speed of the CPU 111, the presence or absence of the GPU 112, the capacity of the RAM 113, and the like. Adjustment of the processing capacity may be performed by selecting a combination of the information processing servers 10 that can obtain the desired processing capacity from among the information processing servers 10a to 10d having different processing capacities. This may be done by changing the processing capability of the information processing server 10 included in 100 at this stage. The processing capability of the information processing server 10 can be changed by, for example, executing processing for switching whether or not the GPU 112 can be used, or executing processing for switching the capacity of the RAM 113 to be used. In the example of FIG. 6, the information processing servers 10a to 10c are selected from among the four information processing servers 10, and the information processing server group 100 is configured.

Next, the control unit 41 (first data management means) copies the compressed image data D1 to be processed from the shared storage 20 to the shared cache device 30 (step S103). As a result, as shown in FIG. 6, the shared cache device 30 stores the compressed image data D1.

Next, the control unit 41 (processing control means, storage control means) causes the information processing server group 100 to decompress the compressed image data D1 (step S104). Here, the control unit 41 causes the three information processing servers 10a to 10c belonging to the information processing server group 100 to share the decompression processing for the compressed image data D1 and perform them in parallel. As a result, the decompressed image data D2 is generated and stored in the shared cache device 30 as shown in FIG. The specific processing to be performed by each of the information processing servers 10a to 10c in step S104 is not particularly limited, and the processing time is shortened compared to the case where one information processing server 10 performs the decompression processing alone. Any processing may be used as long as the processing is shared appropriately. For example, when the compressed image data D1 to be processed consists of a plurality of image files, each of the information processing servers 10a to 10c can decompress separate image files in parallel. Further, as will be described in a fourth embodiment described later, the compressed image data D1 to be processed is divided into a plurality of divided compressed data d1, and each of the information processing servers 10a to 10c performs separate decompression processing of the divided compressed data d1. may be performed in parallel.

Next, the control unit 41 (second data management means) causes the decompressed image data D2 to be transmitted to the terminal device 50, and causes the display unit 54 of the terminal device 50 to display an image related to the decompressed image data D2 ( step S105). Here, as shown in FIG. 7, the control unit 41 reads out the decompressed image data D2 from the shared cache device 30 and sends it to one of the information processing servers 10 . Alternatively, a control command may be transmitted to the information processing server 10 to cause the information processing server 10 to obtain the decompressed image data D2. Next, the information processing server 10 transmits the decompressed image data D2 to the terminal device 50 that transmitted the processing request in step S101. Accordingly, in the terminal device 50 , an image related to the decompressed image data D<b>2 is displayed on the display section 54 under the control of the control section 51 .
When the process of step S105 ends, the control section 41 ends the image display process.

According to such image display processing, according to the content of the compressed image data D1 to be processed and the operation status of the information processing server 10, the information processing server group can most efficiently execute the decompression processing of the compressed image data D1. 100 is constructed, and decompression processing is executed in parallel by two or more information processing servers 10 included in the information processing server group 100 . As a result, the decompression process can be stably executed in a short time.
Also, the decompressed image data D2 obtained as a result of decompression processing is stored in the shared cache device 30 accessible from each information processing server 10 . Therefore, when a processing request for the same compressed image data D1 is made from another terminal device 50, each information processing server 10 can reuse the result of the decompression processing (decompressed image data D2). As a result, it is possible to prevent the information processing server 10 from performing useless decompression processing.

Next, another embodiment of the present invention will be described. In each of the following embodiments, differences from the first embodiment will be described, and descriptions of features common to the first embodiment will be omitted.

It is given only to the information processing servers 10a and 10b belonging to G1. Since the decompressed image data D2 can be restored (combined) only after all the divided decompressed data d2 are available, the 10a and 10b having access rights to all the divided decompressed data d2 can restore and read the decompressed image data D2.

(Tenth embodiment)
The tenth embodiment differs from the first embodiment in that the information processing server group 100 is configured based on the modality that generated the compressed image data D1.

FIG. 21 is a diagram showing a schematic configuration of an information processing system 1 according to the tenth embodiment.
The information processing system 1 of FIG. 21 is a system for displaying medical images on a terminal device 50, and a plurality of types of modalities 60 (medical image generating devices) are connected to a network N1. Here, modalities 60 include CT and DR.

In CT and MR, image data relating to a plurality of different cross-sections of an affected area are usually generated, so the number of image files tends to increase. Therefore, the amount of calculation for decompression processing of the compressed image data D1 is large, and the processing time can be effectively shortened by executing the decompression processing by the information processing server group 100 composed of a large number of information processing servers 10. . In addition, since decompression processing can be easily assigned to each information processing server 10 in units of image files, it is suitable for parallel processing using the information processing server group 100 . For example, if the data to be processed is compressed image data of 2000 images related to one CT examination, and the information processing server group 100 is composed of four information processing servers 10, each information processing server 10 can share the decompression processing of 500 compressed image data.

On the other hand, in DR and the like, although the data amount of one image data is relatively large, the number of image files linked to an examination is small. Therefore, it is preferable to perform the decompression processing by a single information processing server 10 or by the information processing server group 100 consisting of a small number of information processing servers 10, since there is little significance and advantage in performing the decompression processing in parallel.

Therefore, the control unit 41 (scaling means) of the management server 40 of this embodiment determines the configuration of the information processing server group 100 according to the type of the modality 60 that generated the compressed image data D1.
In the example of FIG. 21, when the compressed image data D1 to be processed is generated by CT (or compressed image data generated by CT), the control unit 41 controls the information processing server group. The number of information processing servers 10 included in 100 is increased.
On the other hand, when the compressed image data D1 is generated by DR (or compressed image data generated by DR), the control unit 41 controls the information processing server to be included in the information processing server group 100. 10, or have a single information processing server 10 execute the decompression process. However, even in this case, the information processing server 10 suitable for processing can be appropriately selected. For example, when advanced image processing is required in addition to decompression processing, the information processing server 10a or 10b having the GPU 112 is selected.

As described above, the information processing system 1 according to each of the above-described embodiments includes a plurality of information processing servers 10 and a shared system for storing compressed image data D1 as processing target data to be processed by the plurality of information processing servers 10. A storage 20, a control unit 41, and a shared cache device 30 that can be accessed from each of the plurality of information processing servers 10. The control unit 41 decompresses the compressed image data D1 as predetermined data processing. determines the configuration of the information processing server group 100 for executing the decompression process, which consists of two or more information processing servers 10 out of the plurality of information processing servers 10 (scaling means), according to the execution request of the information processing server The two or more information processing servers 10 belonging to the group 100 share the decompression processing for the compressed image data D1 and perform them in parallel (processing control means), and the shared cache device 30 stores the processed data obtained by the decompression processing. and stores the decompressed image data D2 as .
According to this, the processing time of the decompression process can be shortened compared to the case where the single information processing server 10 executes the decompression process. Also, by determining the configuration of the information processing server group 100 that executes the decompression process each time, the decompression process of the compressed image data D1 can be performed efficiently according to the contents of the compressed image data D1 and the operation status of each information processing server 10. It is possible to construct an information processing server group 100 capable of executing Therefore, it is possible to avoid large fluctuations in the processing time due to the processing capacity of each information processing server 10, and avoid the processing time of the information processing server 10 from becoming a bottleneck in the processing time of the entire system. be able to. As a result, data processing such as decompression processing can be stably executed in a short time.
Also, since the decompressed image data D2 obtained as a result of the decompression process is stored in the shared cache device 30 accessible from each information processing server 10, a processing request for the same compressed image data D1 is issued. In this case, each information processing server 10 can reuse the result of past decompression processing (decompressed image data D2). As a result, it is possible to prevent the information processing server 10 from performing useless decompression processing.

In addition, the control unit 41 selects the information processing servers 10 to be included in the information processing server group 100 based on reference information including at least one of information related to the compressed image data D1 and information related to the operation status of the plurality of information processing servers 10. adjust the number of (scaling means). According to this, it is possible to configure the information processing server group 100 capable of efficiently decompressing the compressed image data D1 according to the content of the compressed image data D1 and the operating status of the information processing server 10 . Therefore, the decompression process can be executed more stably and in a short time. In addition, since it is not necessary to use an expensive server with high processing power for each information processing server 10, it is possible to suppress an increase in the cost of the entire information processing system.

Also, the control unit 41 adjusts the processing capacity of at least a part of the information processing servers 10 included in the information processing server group 100 based on the reference information (scaling means). According to this, when advanced image processing is required or when the calculation amount of decompression processing is large, many information processing servers 10 with high processing performance can be incorporated into the information processing server group 100, or the information processing server group 100 can By changing (increasing) the processing capability of the information processing server 10 incorporated in the data processing server 10, data processing (decompression processing and advanced image processing) for the compressed image data D1 can be performed more efficiently. In addition, since it is not necessary to use an expensive server with high processing power for each information processing server 10, it is possible to suppress an increase in the cost of the entire information processing system.

According to this, the information processing server group 100 capable of executing data processing in a short time can be configured more flexibly according to the number of files and the amount of data of the compressed image data D1 and the content of necessary data processing. Therefore, data processing can be executed by the information processing server group 100 having a more appropriate configuration.

Further, in the information processing system 1 of the fourth embodiment, the control unit 41 distributes part of the divided compressed data d1 of the compressed image data D1 divided into a plurality of divided compressed data d1 to the information processing server group 100.

According to this, even when it is difficult to perform decompression processing in parallel by a large number of information processing servers 10, such as when the number of files of the compressed image data D1 to be processed is small and the amount of data is large, a large number of information processing can be performed. The information processing server group 100 consisting of the servers 10 can execute the decompression process in parallel to shorten the processing time.

Further, in the information processing system 1 of the fourth embodiment, the control unit 41 divides the compressed image data D1 into a plurality of divided compressed data d1 according to the configuration of the information processing server group 100 (processing control means). According to this, since the divided compressed data d1 can be generated with the number of divisions according to the configuration of the information processing server group 100, the decompression processing by the information processing server group 100 can be performed more efficiently.

Further, in the information processing system 1 of the fifth embodiment, the control unit 41 issues a request to execute another decompression process for another compressed image data D1b during execution of one decompression process for one compressed image data D1a. is received, the information processing server group 100 causes the one decompression process and the other decompression process to be performed in parallel (processing control means).
