Process cooperation method, process cooperation program, and process cooperation system

A non-transitory computer-readable storage medium storing a process cooperation program for causing a computer to execute a process comprising:

• storing, by a first processor, in a first storage device a first process result as a result of execution of a first process and transmitting, by the first processor, the first process result to a second processor;
• storing, by a second processor, in a second storage device a second process result as a result of execution of a second process based on the first process result received from the first processor, and transmitting, by the second processor the second process result to a third processor, and moreover transmitting, by the second processor, the second process result and an identifier identifying the third processor to the first processor;
• storing, by the first processor, in the first storage device the second process result and the identifier received from the second processor in association with the first process result;
• and
• extracting, by the first processor, the second process result and the identifier stored in association with the first process result and transmitting, by the first processor, the second process result to the third processor identified by the identifier without transmitting a process result of the first process to the second processor, in a case where the process result of the first process matches the first process result stored in the first storage device.

A process cooperation system comprising:

• a first processor,
• a second processor, and
• a third processor, wherein
• the first processor configured to store in a first storage device a first process result as a result of execution of a first process and transmits the first process result to the second processor,
• the second processor configured to store in a second storage device a second process result as a result of execution of a second process based on the first process result received from the first processor, transmit the second process result to the third processor, and transmit the second process result and an identifier identifying the third processor to the first processor,
• the first processor configured to store in the first storage device the second process result and the identifier received from the second processor in association with the first process result, and
• the first processor configured to extract the second process result and the identifier stored in association with the first process result, and transmit the second process result to the third processor identified by the identifier without transmitting a process result of the first process to the second processor, in a case where the process result of the first process matches the first process result stored in the first storage device.
