Description

  The present invention relates to a distributed processing system, a distributed processing method, and a program for upload data.

  When providing a service on the Web, the amount of data for a single piece of data is enormous, and when some processing is performed, the processing result is provided to the user, but in some cases it cannot be processed in real time. Exists. For example, Japanese-English translation processing, Japanese dependency analysis processing, attention scene extraction from video, and the like. Specifically, in the case of Japanese dependency analysis processing, there is a case where the dependency analysis processing takes 100 seconds for a certain design document 16000 lines (700 KB). In this case, if this process is executed as a service via a Web browser, a browser timeout occurs before 100 seconds. Therefore, conventionally, the following measures have been taken in such a case.

  (1) Prohibit input of data with a large amount of information. There are a large number of service systems that provide such restrictions, but there is a problem that the service itself cannot be used in the first place if the restrictions required of the user are too strict.

  (2) An asynchronous result confirmation interface is provided. In preparation for cases where users cannot respond within the browser timeout period, new processing groups such as notifying the user by e-mail after processing is completed, for example, e-mail address registration, e-mail transmission, error resending, result progress status inquiry Prepare etc. In this case, there is a problem that the processing configuration becomes complicated in a non-essential part of the system.

  (3) The processing result is generated in a storage area or the like where user authentication is possible, and the user confirms that the result is generated at an appropriate time. In this case, in order to obtain a result that the user does not know when it is generated, it is necessary to confirm the result many times, and there is a problem that the burden on the user increases.

  On the other hand, there is a MapReduce model as a technique for speeding up processing by utilizing a large number of PC groups (see Non-Patent Document 1). The MapReduce model stores, for example, a detailed data group (Web page group) obtained by crawling the Web on a distributed file system (GFS), and performs morphological analysis processing and word processing on a machine that provides each distributed file system. The counting process is executed in parallel. Thereby, it is possible to create a transposed file in a short time for a huge file group having a total capacity of 10 TB.

  Also, a distributed configuration has been proposed as a technique for improving the system throughput (see Patent Document 1). In this distributed configuration, there are a plurality of reception queues and a plurality of processing units, a plurality of data are received by a plurality of reception queues, and a plurality of received data are distributed and processed by each processing unit. Thus, the throughput of the entire system can be improved. This system is called a write-once reference type DMS (Data Management System) or simply DMS.

There are strong restrictions such as the need to register data, and it is suitable for batch processing and not for real-time processing. Therefore, it cannot be applied to speeding up the targeted processing in response to data uploaded from the user.

Details of the fragment data generation processing by the fragment data generation unit 22 will be described later with reference to FIG.

  The data management unit 23 receives fragment data every time fragment data is generated by the fragment data generation unit 22, assigns sequential IDs in the order of generation of each fragment data, and the fragment data generation unit 22 A flag (last flag) that can be identified as the last is added to the last fragment data that has been cut out. Then, when there are a plurality of queue management devices 30, the data management unit 23 determines the queue management device 30 as the data output destination using the round robin method or the like, and sends the determined queue management device 30 to the determined queue management device 30. The fragment data is transmitted (step S107). Subsequently, the data management unit 23 cuts out all of the data read by the data reading unit 21 and determines whether all of the fragment data has been transmitted (step S108). If there is still data being read and all of the fragment data has not been transmitted (step S108 → No), the process returns to step S105, and the data reading unit 21 continues to read the data. On the other hand, if all of the fragment data has been transmitted (step S108 → Yes), the process is terminated.

  Next, the queue receiving unit 31 of the queue management device 30 receives the fragment data with the ID from the dividing and integrating device 20 (step S109) and stores it as a queue in the queue storage unit 33. In response to a fragment data acquisition request from the processing device 40 (40a, 40b, 40c,...), The queue management unit 32 converts the fragment data stored in the queue storage unit 33 into the processing device 40 (40a, 40b,. 40c,...) (Step S110).

  Subsequently, the queue selection unit 41 of the processing device 40 selects the queue management device 30 from which the fragment data is acquired using the round robin method or the like (step S111). Then, the fragment data acquisition unit 42 of the processing device 40 transmits a fragment data acquisition request to the queue management device 30 selected by the queue selection unit 41, and acquires fragment data from the queue management device 30 (step S112). ). Next, the data processing unit 43 performs predetermined data processing on the fragment data acquired by the fragment data acquisition unit 42 (step S113). Then, the fragment result data output unit 44 transmits the fragment result data, which is the processing result of the data processing unit 43, to the dividing and integrating device 20 (step S114).

  For example, the processing device 40 acquires fragment data of Japanese text from the queue management device 30 and performs a Japanese-English translation process in the data processing unit 43. Then, the fragment result data obtained as a result of the data processing is output to the dividing and integrating device 20 with the ID attached to the fragment data attached. Further, the processing device 40 different from the one processing device 40 performs the same processing, and each fragment result data subjected to data processing in each processing device 40 (40a, 40b, 40c,...) Is divided and integrated. 20 is transmitted.

  In this way, data processing such as Japanese-English translation processing, which requires processing time, is divided into a plurality of pieces of fragment data and then distributed and executed in a plurality of processing devices 40, thereby reducing the overall processing time. Is possible.

  Next, the fragment result data acquisition unit 24 of the division integration device 20 acquires fragment result data from each processing device 40 (40a, 40b, 40c,...) (Step S115). The fragment result data integration unit 25 converts the ID attached to the fragment result data acquired by the fragment result data acquisition unit 24 into a file name or the like and stores the file in the data storage unit 27. Further, the fragment result data integration unit 25 determines whether or not the last flag is given to the acquired fragment result data. Then, when the fragment result data integration unit 25 acquires the fragment data after acquiring the fragment result data to which the last flag is added, the fragment result data integration unit 25 converts the ID assigned to the fragment data into a file name or the like as a file. At the same time, it is determined whether or not all pieces of fragment data have been acquired (step S116).

  If there is fragment data that has not yet been acquired (step S116 → No), the process returns to step S115 to continue acquiring fragment data. On the other hand, when all pieces of fragment data have been acquired (step S116 → Yes), the acquisition process ends, and the fragment result data integration unit 25 merges the fragment result data by merging in the order of IDs attached to the files. Result data is generated (step S117), and the generated result data is stored in the data storage unit 27.

  Subsequently, the result data output unit 26 generates a processing completion notification and transmits the processing completion notification to the reception response device 10 (step S118). Next, the data reception unit 11 of the reception response device 10 that has received the processing completion notification transmits the processing completion notification to the user terminal 2 via the transmission control unit 13 (that is, the result data is asynchronously transmitted to the user terminal 2). Reply) (step S119). In step S118, when the result data output unit 26 of the division integration device 20 transmits the process completion notification to the reception response device 10, the result data is transmitted together with the processing completion notification to the reception response device 10. Then, it may be transmitted from the acceptance response device 10 to the user terminal 2 (that is, the result data is returned to the user terminal 2 synchronously). Then, the user terminal 2 receives the process completion notification (result data) and ends the process (step S120).

(Fragment data generation process)
Next, the fragment data generation process performed by the fragment data generation unit 22 of the division integration device 20 in step S106 of FIG. 2 will be described. FIG. 3 is a flowchart showing a flow of fragment data generation processing performed by the text fragment data generation unit 221 of the fragmentation integration apparatus 20 according to the first embodiment of the present invention. In the present embodiment, the Japanese text data shown in FIG. 4 is uploaded, and this data is subjected to a Japanese-English translation process by the processing device 40, thereby converting it into English text data shown in FIG. Will be described. In this case, the text fragment data generation unit 221 provided in the fragment data generation unit 22 of the fragmentation integration device 20 is a unit that can be processed when the processing device performs data processing based on the data size and the data pattern. Fragment data is generated by cutting out. For example, a pattern is searched forward (or backward) from the last point of the data read from a predetermined number of bytes. This pattern determines whether there is a punctuation character followed by a line feed code. When this pattern exists, the data up to that point is cut out as fragment data as a part that can be processed when the processing unit processes the data. This will be specifically described below.

  First, the fragment data generation unit 22 determines the type of data that the data reading unit 21 has started reading. Here, it is determined whether or not the data type is Japanese text data (step S201). If the data read by the data reading unit 21 is not Japanese text data (step S201 → No), the process is terminated. On the other hand, if the read data is Japanese text data (step S201 → Yes), the process proceeds to the next step S202.

  In step S202, the text fragment data generation unit 221 provided in the fragment data generation unit 22 first reads a predetermined amount of data. For example, data from the beginning of the Japanese text data shown in FIG. 4 to a point with a data size of 1024 KB is read.

  Next, the text fragment data generation unit 221 determines whether or not the end of the file exists when reading the data in step S202 (step S203). If the end of the file exists (step S203 → Yes), the text fragment data generation unit 221 cuts out as the last fragment data (step S207), and ends the fragment data generation processing. On the other hand, if the end of the file does not exist (step S203 → No), the process proceeds to the next step S204.

  In step S204, the text fragment data generation unit 221 performs a pattern search forward (or backward). Specifically, the text fragment data generation unit 221 determines whether or not there is a punctuation character followed by a line feed code (step S205). If there is no punctuation character and the following line feed code (step S205 → No), the pattern search continues further forward (or backward). On the other hand, when there is a punctuation character and a subsequent line feed code (step S205 → Yes), the text fragment data generation unit 221 cuts out to that point, generates fragment data (step S206), and proceeds to step S202. Return.

  The above process will be described using a specific example. As shown in FIG. 4, if the last point with a data size of 1024 KB from the beginning is the “flow” character at the point 401, the punctuation character “.” Followed by a new line The point where the code “↓” exists, that is, up to the end of the line of the line number “05” is generated as fragment data as a part that can be processed when the processing apparatus processes data. Next, in the second and subsequent times, reading is performed from the position immediately after cutting out as fragment data to the point of 1024 KB, not the point of 1024 KB from the beginning. In FIG. 4, assuming that a point with a data size of 1024 KB from the head of the line number “06” is a “chain” character at the point of reference numeral 402, a punctuation character “.” Followed by a new line The point where the code “↓” exists, that is, up to the end of the line of the line number “12”, is generated as fragment data that is a part that can be processed when the processing apparatus processes data.

  FIG. 6 is a diagram illustrating an example of fragment data generated by the text fragment data generation unit 221 of the fragmentation integration device 20 according to the first embodiment of the present invention. As shown in FIG. 6, in the fragment data generated by the text fragment data generation unit 221, the sentence is interrupted as Japanese by performing a pattern search as compared to the case where the data is simply divided based on the data size. Never. Therefore, the fragment data can be cut out as data as a unit that can be processed when the processing apparatus processes the data.

  It should be noted that the effect of shortening the response (response time) by the distributed processing using the distributed processing system 1 according to the first embodiment of the present invention can be expected in the following cases.

This is the case of D << P and M << P, where D is the data division time in the division integration device 20, M is the integration time in the division integration device 20, and P is the processing time in the processing device 40. For example, in the Japanese-English translation processing shown in the first embodiment of the present invention, the time for dividing Japanese text is D ₁ , the time for integrating English text is M ₁ , and the time for translation processing is P _1. Since the time D ₁ and the integration time M ₁ are much shorter than the translation processing time P ₁ , a significant distributed processing effect can be expected.

  Further, the text fragment data generation unit 221 according to the first embodiment of the present invention has been described as performing the fragment data generation processing of Japanese text data as the Japanese text fragment data generation unit. On the other hand, when the English text data is uploaded to the reception response device 10 and the processing device 40 performs an English-Japanese translation process and converts it into Japanese text data, the English text data is used as the text fragment data generation unit 221. A fragment data generation unit may be provided to perform fragment data generation processing of English text data. In this case, the English text fragment data generation unit reads a predetermined amount of data, and detects a period and a subsequent line feed code from the end of the read data forward or backward. Then, fragment data generation processing can be performed by cutting out the detected points as fragment data as a portion that can be processed when the processing device processes the data.

  As described above, according to the distributed processing system 1 according to the first embodiment of the present invention, the user terminal 2 can be obtained by preparing a plurality of processing devices 40 even for a single data having a large amount of information. The response speed can be increased in response to the processing request from. Therefore, the result can be returned to the user terminal 2 within the browser timeout time. In addition, it is possible to omit the construction of an accompanying system (system for e-mail address registration, e-mail transmission, etc.) such as notification of the processing result after the fact.

<< Second Embodiment >>
Next, a distributed processing system 1a according to a second embodiment of the present invention will be described. The difference from the distributed processing system 1 according to the first embodiment of the present invention is that the file processing unit 12 of the reception response device 10 further includes a sequential file processing unit 121 as shown in FIG. . The distributed processing system 1a according to the second embodiment, in addition to the effect of shortening the response (response time) by distributing and processing data obtained by the distributed processing system 1 according to the first embodiment, The sequential file processing unit 121 starts uploading data and activates the division integration device 20 to create a file while receiving data. And the process which transmits to the division | segmentation integration apparatus 20 in order from the file-ized data is performed, without waiting for upload of all the data. By doing so, the response (response time) is further shortened. This will be specifically described below.

  In the processing of the file processing unit 12 according to the first embodiment of the present invention, after the data reception unit 11 completes reception of all data, the data is filed and stored in the data storage unit 14, and then An activation instruction message was output to the dividing and integrating device 20 (see steps S102 to S104 in FIG. 2). On the other hand, when the data reception unit 11 starts to accept data from the user terminal 2, the sequential file processing unit 121 according to the second embodiment of the present invention first transmits an activation instruction message to the division integration device 20. Each time the sequential file processing unit 121 receives a predetermined amount (for example, 10 bytes) of data, the sequential data processing unit 121 converts the received data into a file and stores it in the data storage unit 14, and sequentially stores the stored data to the dividing and integrating device 20. Send.

  By doing in this way, without waiting for the upload of all the data by the reception response apparatus 10, it can transmit to the division | segmentation integration apparatus 20 in order from the received data, and a response (response time) can further be shortened. .

  FIG. 7 is a sequence diagram showing the flow of distributed processing of the distributed processing system 1a according to the second embodiment of the present invention. The same processes as those in the sequence according to the first embodiment of the present invention (see FIG. 2) are denoted by the same reference numerals and description thereof is omitted.

  First, when data is transmitted from the user terminal 2 via the network 3 (step S101), the data reception unit 11 of the reception response device 10 receives the data, and the sequential file processing unit 121 is triggered by the reception of the data. However, an activation instruction message is transmitted to the division integration device 20 via the transmission control unit 13 (step S301). And the division | segmentation integration apparatus 20 will start and will be in a data reading waiting state by receiving this starting instruction | indication message (step S302).

  Next, every time the data reception unit 11 receives a predetermined amount (for example, 10 bytes) of data, the sequential file processing unit 121 of the reception response device 10 sequentially converts the received data into a file and stores it in the data storage unit 14. The stored data is sequentially transmitted to the dividing and integrating device 20 (step S303). Then, the sequential file processing unit 121 determines whether reading of all uploaded data and transmission to the dividing and integrating device 20 have been completed (step S304). If there is data that has not yet been read and transmitted (step S304 → No), the process returns to step S303 to continue the processing. On the other hand, if all the data has been read and transmitted (step S304 → Yes), the process ends.

The data reading unit 21 of the dividing and integrating device 20 reads the data acquired from the reception response device 10 without waiting for the completion of reception of all data (step S105), and the read data is sent to the fragment data generating unit 22. hand over. Next, the fragment data generation unit 22 sequentially reads data and performs fragment data generation processing (step S106). Then, the data management unit 23 transmits the generated fragment data to the queue management device 30 (step S107).
In the following, processing similar to that in steps S108 to S120 shown in FIG.

  As described above, according to the distributed processing system 1a according to the second embodiment of the present invention, data upload processing from the user terminal 2 to the reception response device 10, fragment data generation processing by the division integration device 20, and Since the fragment data can be transmitted to the queue management device 30 in parallel, the response (response time) can be further shortened.

<< Third Embodiment >>
Next, a distributed processing system 1b according to a third embodiment of the present invention will be described. The difference from the distributed processing system 1 according to the first embodiment of the present invention is that data uploaded from the user terminal 2 is video data (video content). This video data is, for example, mpeg2 or H.264. H.264 video or its successor codec or derivative codec. In order to divide the video data, the fragment data generation unit 22 includes a video fragment data generation unit 222 in the fragment data generation unit 22 of the division integration device 20 as shown in FIG. Note that the processing performed by the processing device 40 for uploading the video data includes, for example, a cut point detection process for detecting a cut point at which one video is switched to another video, and a subject such as a person is greatly captured. For example, a noticed scene detection process for detecting a noticed scene such as an up-shot is provided.

This video fragment data generation unit 222 uses GOP (Group Of Pictures) as one non-dividable unit when cutting out fragment data from video data, and converts video data including a predetermined number of GOPs into one or more video data. Cut out as fragment data that is a set of video scenes.
Then, the fragment data generated by the video fragment data generation unit 222 is transmitted to the queue management device 30 by the data management unit 23 as in the first embodiment, and the processing device 40 performs the cut inspection for each piece of fragment data. Out processing and attention scene detection processing are performed.

Next, fragment data generation processing performed by the video fragment data generation unit 222 will be described.
FIG. 8 is a flowchart showing a flow of fragment data generation processing performed by the video fragment data generation unit 222 of the fragmentation integration device 20 according to the third embodiment of the present invention.

  First, the fragment data generation unit 22 determines the type of data that the data reading unit 21 has started reading. Here, the data type is mpeg2 or H.264. It is determined whether the video data is H.264 video or video data of a successor codec or a derived codec (step S401). If the data read by the data reading unit 21 is not video data such as mpeg2 (step S401 → No), the process ends. On the other hand, if the read data is video data such as mpeg2 (step S401 → Yes), the process proceeds to the next step S402.

  In step S402, the video fragment data generation unit 222 provided in the fragment data generation unit 22 cuts out data included in a predetermined number of GOPs. Next, the video fragment data generation unit 222 determines whether or not the end of the file exists when reading the data (step S403). When the end of the file exists (step S403 → Yes), the video fragment data generation unit 222 cuts out the read data as the last fragment data (step S405), and includes the fragment in the container (moving image file). Generate data. On the other hand, when the end of the file does not exist (step S403 → No), the video fragment data generation unit 222 includes the data extracted in step S402 in the container to generate fragment data (step S404). Return to step S402.

  Compared with the case where the processing for cutting out fragment data by executing decoding for each video is performed, according to the clipping in units of GOP by the video fragment data generation unit 222 according to the third embodiment of the present invention, the processing device 40 Compared to the processing time P, the division time D in the division integration device 20 can be greatly shortened, so that D << P can be realized. In addition, since the cut point detection process and the target scene detection process result in a frame number in the video, it is only necessary to generate an image corresponding to the frame number, and a series of uploaded video data data. Compared with the amount, the data amount of the output information is remarkably reduced, and the integration time M << processing time P in the dividing and integrating device 20 is satisfied, and the distributed processing effect according to the present invention can be enjoyed.

  Also, for example, the video of the mpeg2 codec is The present invention can also be applied to the case where the processing device 40 performs the process of converting to an H.264 codec video. However, when a plurality of converted fragment result videos (videos encoded in H.264) are combined, there is a case where the cost of the integration time M is high and the state of M << P cannot be realized. In that case, by integrating a plurality of video containers and using a playlist or the like that is regarded as one video container as a combined result, the load of integration can be reduced, and the state of M << P can be realized. It is possible to enjoy the distributed processing effect.

  As described above, according to the distributed processing system 1b according to the third embodiment of the present invention, a plurality of processing devices 40 are prepared when a single piece of video data (or content) with a large amount of information is input. By doing so, it becomes possible to shorten the response (response time) to the processing request from the user.

  In the distributed processing system 1b according to the third embodiment of the present invention, the fragment data generation unit 22 of the fragmentation integration device 20 includes the video fragment data generation unit 222. A fragment data generation unit may be provided. In this case, the audio fragment data generation unit processes the audio data received by the reception response device 10 by, for example, cutting out the data by separating a portion where the silent time of the audio data continues for a predetermined time as a delimiter. In this case, fragment data is generated as a unit that can be processed. Then, for example, data processing for converting the fragment data (voice data) into Japanese text data can be executed in the processing device 40 via the queue management device 30.

<< Modification of this embodiment >>
Next, a modified example of the distributed processing system 1 according to the embodiment of the present invention will be described. FIG. 9 is a configuration diagram for explaining a modification of the distributed processing system 1 according to the present embodiment. A system 100 shown in FIG. 9 is obtained by applying a postscript reference type DMS (Data Management System) 4 described in Patent Document 1 described above, instead of the reception response device 10 of the distributed processing system 1 shown in FIG. .

  In the DMS 4, when a plurality of data is uploaded from a plurality of user terminals 2 via the network 3, the reception distribution device 50 distributes and stores the received data to the plurality of additional recording devices 60, and performs a plurality of processes. The device 70 acquires data from the appending device 60 and processes the data. Then, the processing result of each processing device 70 is transmitted to the reception distribution device 50 and returned to the user terminal 2. Thus, according to the DMS 4, a plurality of data can be processed in parallel, and the throughput of the entire system can be improved.

  In this system 100, the DMS 4 is provided instead of the reception response device 10 of the distributed processing system 1 according to the present embodiment. Here, it is assumed that the processing device 70 of the DMS 4 performs the Folder Engine processing. For example, when the user selects a plurality of data files using the GUI function of the user terminal 2 and batch DROPs the folder, the Folder Engine process is a process indicated by the folder name as a processed folder. , And each processing result is stored in a folder. In the Folder Engine processing, a folder with processing can be further inserted into one folder with processing by the nested structure of the folder with processing. For example, there is a case where certain image data is converted into Japanese text data by OCR processing, further, Japanese-English translation processing is performed on the Japanese text data, and the English summarization processing is further performed. Such processing can be collectively processed by the nested structure of folders with processing.

  When this processing is performed in the present system 100, data is acquired from the processing device 70 of the DMS4. (1) First, the OCR processing device 45 performs OCR processing. (2) Next, the result data is The processing device 70 transmits to the division integration device 20 of the distributed processing system 1. Then, the data is divided by the division integration device 20 to generate fragment data. Subsequently, each processing device 40 acquires the fragment data stored in the queue management device 30, translates the Japanese text data into English text data, and transmits the fragment result data to the fragmentation integration device 20. The fragmentation integration device 20 integrates the fragment result data, and transmits the integrated result data to the processing device 70 of the DMS 4. (3) Then, the English summary processing unit 46 performs English text data summarization processing. By performing such processing, a response (response time) by the processing device 70 can be shortened. Further, when these processes are requested simultaneously from a large number of user terminals 2 (that is, when uploading at the same time), the processing device 70 operates simultaneously, thereby improving the system throughput.

  As described above, according to the present system 100, it is possible to improve the throughput with respect to requests from a large number of users by using the DMS4. Further, even for data having a large amount of information input from the users, By combining the distributed processing system 1 according to the present embodiment, the response (response time) can be improved.
