Information processing apparatus, distributed processing system, non-transitory computer readable medium storing program, and distributed processing method for acquiring a processing result of processing according to an execution instruction for the processing

A distributed processing system comprising a plurality of servers that executes distributed processing in response to an instruction from a terminal apparatus and provides processing results to the terminal apparatus,

• wherein each server in the plurality of servers
• acquires an execution instruction for processing and apparatus identification information for identifying the terminal apparatus from the terminal apparatus,
• executes processing distributed to the server in the distributed processing in response to the execution instruction,
• transmits identification information of the executed processing and the apparatus identification information for identifying the terminal apparatus to the terminal apparatus and transmits the processing result to the terminal apparatus in response to a response from the terminal apparatus indicating that the apparatus identification information for identifying the terminal apparatus matches apparatus identification information of the terminal apparatus, and
• in response to determining that a notification, which indicates that the processing result has not been acquired for any of respective processing in the distributed processing, is received from the terminal apparatus and at least one of the processing related to the notification is distributed to the server, executes the processing that is newly distributed and transmits the processing result to the terminal apparatus.

A non-transitory computer readable medium storing a program causing a computer to execute:

• a function of providing an execution instruction for processing and apparatus identification information of an information processing apparatus to a plurality of servers that execute distributed processing;
• a function of receiving identification information of the processing and the apparatus identification information of the information processing apparatus from each of the plurality of servers and acquiring a processing result of the processing identified by the identification information of the processing acquired together with the apparatus identification information from the server that is a transmission source of the apparatus identification information;
• a function of repeating to provide, in response to determining that a predetermined condition is satisfied without acquiring the processing result for respective processing related to the distributed processing, a notification indicating that the processing result has not been acquired to each of the plurality of servers that executes the distributed processing;
• a function of determining whether a number of times of the notification has reached a predetermined number of times;
• and
• a function of receiving, in response to determining that the number of times of the notification has not reached the predetermined number of times, the apparatus identification information of the information processing apparatus from any server in the servers that execute the distributed processing and acquiring the processing result that has not been acquired in response to determining that the condition is satisfied.

A distributed processing method comprising:

• providing an execution instruction for processing and apparatus identification information of an information processing apparatus to a plurality of servers that execute distributed processing;
• receiving identification information of the processing and the apparatus identification information of the information processing apparatus from each of the plurality of servers and acquiring a processing result of the processing identified by the identification information of the processing acquired together with the apparatus identification information from the server that is a transmission source of the apparatus identification information;
• repeating to provide, in response to determining that a predetermined condition is satisfied without acquiring the processing result for respective processing related to the distributed processing, a notification indicating that the processing result has not been acquired to each of the plurality of servers that executes the distributed processing;
• determining whether a number of times of the notification has reached a predetermined number of times;
• and
• receiving, in response to determining that the number of times of the notification has not reached the predetermined number of times, the apparatus identification information of the information processing apparatus from any server in the servers that execute the distributed processing and acquiring the processing result that has not been acquired in response to determining that the condition is satisfied.
