Abstract

The embodiment of the invention provides a memory management method, device and system.The memory management method comprises the steps that a client can obtain a memory application instruction, the memory application instruction carries an application identifier, and when the application identifier is a specified identifier, it is indicated that a large-size memory page needs to be applied; at the moment, the first target memory page corresponding to the first size identifier can be determined from the memory pages of the client, the first size identifier is the identifier of the host memory page of which the memory size is greater than the preset size threshold, and then the first target memory page is allocated to the memory application instruction, so that the client can provide additional memory allocation support, and the memory allocation efficiency is improved. Whether the large-size host machine memory page is needed or not is allowed to be indicated when the memory is applied, so that the client can efficiently manage the memory, the large-size host machine memory page can be allocated to the really needed application instruction, the memory space is reasonably utilized, the income of the large-size host machine memory page is optimized, and the memory utilization efficiency is improved.

Description

technical field [0001] The embodiments of this specification relate to the technical field of computers, and in particular to a memory management method. One or more embodiments of this specification also relate to a memory management device, a memory management system, a computing device, and a computer-readable storage medium. Background technique [0002] With the rapid development of computer technology and Internet technology, the demand for data storage has increased sharply, and the capacity of computer memory has also increased explosively. In order to meet the growing demand for data processing and data storage, virtual technology was born accordingly. Virtual technology is a By combining or partitioning existing computer resources (central processing unit, memory, disk space, etc.), these resources appear as one or more operating environments, thereby providing access methods that are superior to the original resource configuration, that is, virtualization Technol...
