Distributed processing system and method for management of distributed processing system

A method for management of a distributed processing system in a distributed processing system that is configured to include a plurality of information processing apparatuses communicably coupled to one another and each including a processor and a memory and is capable of performing parallel processing in which the information processing apparatus performs predetermined processing in parallel with the other information processing apparatuses,

• the information processing apparatus including the processor and the memory executing:
• configuration-information storing processing for storing configuration information, which is information concerning a number of the information processing apparatuses configuring the distributed Processing system and a combination of the information processing apparatuses;
• state monitoring processing for monitoring an operation state of each of the information processing apparatuses;
• and
• system reconfiguration processing for, when detecting a change of the operation state of the information processing apparatus, changing the configuration information on the basis of a number and a combination of the information processing apparatuses in operation and causing, on the basis of the changed configuration information, at least one or more of the information processing apparatuses in operation to perform the predetermined processing independently or in parallel.
