Information processing device, information processing method, and storage medium

An information processing method by which an information processing device configured to be employed in a vehicle control system controls access to a shared storage, the vehicle control system including multiple electronic control units connected to each other via a network and the shared storage accessed by multiple applications executed by the respective electronic control units, the information processing method comprising:

• a first step of creating multiple threads by a processor of the information processing device;
• a second step of storing, by the processor and in a memory, access requests for access to the shared storage by the applications and adding the access requests for access to a queue such that the access requests are lined up before proceeding with processes in the applications;
• and
• a third step of executing, by the processor, the access requests lined up in the queue using free ones of the threads, created through the first step, in the order in which the access requests were added to the queue.

A non-transitory computer-readable storage medium, storing an information processing program that includes instructions to be executed by a processor of an information processing device configured to be employed in a vehicle control system, wherein

• the vehicle control system including
• multiple electronic control units connected to each other via a network, and
• a shared storage accessed by multiple applications executed by the respective electronic control units,
• the instructions cause the processor to
• create multiple threads,
• store, in a memory, access requests for access to the shared storage by the applications and add the access requests for access to a queue such that the access requests are lined up before proceeding with processes in the applications, and
• execute the access requests lined up in the queue using free ones of the threads in the order in which the access requests were added to the queue.
