Information processing device, information processing method, and non-transitory computer-readable recording medium for recording program

An information processing method executed by an information processing device comprising a first processor core in which an operating system is installed and a second processor core controlled by the first processor core and capable of executing parallel operation processing, the information processing method comprising:

• by the second processor core, when detecting the page fault, stopping new issue of an instruction and stopping in a state where an issued and uncompleted instruction can be restarted, and also sending notification that the page fault has been detected to the first processor core;
• and
• by the first processor core:
• judging whether or not the page fault is permissible in response to reception of the notification;
• updating a page table included by the second processor core in accordance with a result of the judgment;
• and
• sending a direction corresponding to a result of the judgment to the second processor core.

A non-transitory computer-readable medium storing a program comprising instructions for, in an information processing device comprising a first processor core in which an operating system is installed and a second processor core controlled by the first processor core and capable of executing parallel operation processing:

• causing the second processor core to realize a process of, when detecting the page fault, stopping new issue of an instruction and stopping in a state where an issued and uncompleted instruction can be restarted, and also sending notification that the page fault is detected to the first processor core;
• and
• causing the first processor core to realize:
• a permissibility judgment part configured to, in response to reception of the notification, judge whether or not the page fault is permissible;
• a page table updating part configured to update a page table included by the second processor core in accordance with a result of the judgment by the permissibility judgment part;
• and
• a directing part configured to send a direction corresponding to a result of the judgment by the permissibility judgment part to the second processor core.
