Computer system, data management method, and recording medium storing program

A data management method for a computer system including a plurality of processing units that each acquire pre-processing data, each execute a given processing on the pre-processing data, and each generate post-processing data as a result of the processing, and transmit a search result in response to a request for searching the post-processing data,

• the method comprising:
• newly allocating a respective process identifier (ID) from among a plurality of process IDs for one of the plurality of processing units each time the one of the plurality of processing units is to acquire the pre-processing data, wherein the process IDs collectively indicate an order of acquisition of the pre-processing data by the plurality of processing units;
• managing a process management ID table that includes information of the processing units in correspondence with the process IDs which have been allocated to the processing units when the pre-processing data has been acquired by the processing units, the process management ID table being managed in ascending order of the process IDs;
• storing the post-processing data generated by the processing of each of the processing units in a storage device in association with the corresponding allocated process IDs;
• determining the post-processing data that satisfies a received data search condition from a search request source;
• and
• extracting the post-processing data associated with a same or earlier process ID than a first process ID that is earliest among the respective latest allocated processing IDs of the plurality of the processing units from the determined post-processing data that satisfies the search condition, and outputting the extracted post-processing data to the search request source.

A non-transitory computer readable recording medium storing a program for causing a computer system having a plurality of processing units to each execute processing to acquire pre-processing data, each execute a given processing on the pre-processing data, and each generate post-processing data as a result of the processing, the program further causing the computer system to:

• newly allocate a respective process identifier (ID) from among a plurality of process IDs for one of the plurality of processing units each time the one of the plurality of processing units is to acquire the pre-processing data, wherein the process IDs collectively indicate an order of acquisition of the pre-processing data by the plurality of processing units;
• manage a process management ID table that includes information of the processing units in correspondence with the process IDs which have been allocated to the processing units when the pre-processing data has been acquired by the processing units, the process management ID table being managed in ascending order of the process IDs;
• store the post-processing data generated by the processing of each of the plurality of processing units in the storage device in association with the corresponding allocated process IDs;
• determine the post-processing data that satisfies a received data search condition from a search request source;
• and
• extract the post-processing data associated with a same or earlier process ID than a first process ID that is earliest among the respective latest allocated processing IDs of the plurality of the processing units from the determined post-processing data that satisfies the data search condition, and output the extracted post-processing data to the search request source.
