Cluster operating system implementation method and apparatus, device, and storage medium

A computing processing device, comprising:

• a memory having stored thereon computer-readable codes;
• and
• one or more processors, wherein when the computer-readable codes are executed by the one or more processors, the computing processing device performs operations of:
• obtaining a permanent virtual memory by mapping a physical memory provided by each of computing nodes in the cluster operating system, wherein the permanent virtual memory comprises segments of a plurality of types of virtual spaces;
• mapping a plurality of segments in the permanent virtual memory to a device of each of the computing nodes;
• and
• performing, on a device of a computing node to which a segment is mapped, operations of an application process on the segment in the permanent virtual memory, wherein each of the computing nodes in the cluster operating system has an application process running on it.

A non-transitory computer-readable storage medium, having stored thereon a computer program comprising computer-readable codes which, when running on a computing processing device, cause the computing processing device to perform operations of:

• obtaining a permanent virtual memory by mapping a physical memory provided by each of computing nodes in the cluster operating system, wherein the permanent virtual memory comprises segments of a plurality of types of virtual spaces;
• mapping a plurality of segments in the permanent virtual memory to a device of each of the computing nodes;
• and
• performing, on a device of a computing node to which a segment is mapped, operations of an application process on the segment in the permanent virtual memory, wherein each of the computing nodes in the cluster operating system has an application process running on it.
