Abstract: A remote resource access method and a switching device are provided. According to the remote resource access method, when a computer system access the remote physical resource device, after obtaining a first access message, including a virtual address of a virtual resource device, from a computing node in the computer system, the switching device converts the first access message into a second access message based on a physical address of a physical resource device corresponding to the virtual address of the virtual resource device. Then, the switching device sends the second access message to the remote physical resource device corresponding to the physical address using a network, thereby implementing the data transmission between the local computer system and the remote physical resource device.

Abstract: A resource processing method, an operating system, and a device are provided. The method is applied to a multi-core operating system, where the multi-core operating system includes a management operating system and multiple load operating systems that run on a host machine and includes a physical resource pool. According to the method, after selecting, in processor cores allocated to a first load operating system, a startup processor core that starts up the first load operating system, the management operating system instructs the startup processor core to read a mapping relationship that is from a virtual memory address to a physical memory address and that is required for executing a startup mirror of the first load operating system. Then, the management operating system instructs the startup processor core to execute the startup mirror pre-constructed for the first load operating system to start up the first load operating system.

Abstract: A global memory sharing method includes counting, by the sub-operating system, a page replacement rate in a task scheduling period of a predetermined quantity of times, and a memory residence time ratio in a page replacement period; calculating, by the sub-operating system, a memory pressure index according to the page replacement rate and the memory residence time ratio; and if the memory pressure index is greater than a memory pressure threshold, sending, by the sub-operating system, an application to a global memory management service module. According to the forgoing method, in an architecture of multiple operating systems, each sub-operating system can complete much adaptive work, which reduces complexity of the global memory management service module and improves system performance. Meanwhile, a utilization rate of global memory may be improved, and the architecture of the multiple operating systems may have better extensibility.
