A method and device for realizing memory fusion

Abstract

The invention discloses a method and a device for implementing memory fusion. The method comprises the following steps of receiving a memory request of a local host and carrying out memory sectioning; confirming the memory allocation priority level of a remote sub-computer through a memory allocation table, and pairing memory sections for the remote extension; acquiring the memory resource of the remote sub-computer in a way of integrating the memory sections through memory address mapping; allocating a memory backup area to backup memory data corresponding to the memory sections at real time; carrying out memory checking at real time during using the memory of the remote extension, and providing memory correction and backup recovery. The device comprises a request processing module, a memory allocation table module, a memory acquisition module, a backup module and a correction module. According to the method and the device for implementing memory fusion, the idlememory of the remote sub-computer is called through network, and is integrated into the local host so as to be used as physical address extensions or paging file cache of the local host, so that the speed of the local application program is optimized, and better memory sharing performance and expansibility are provided for establishing a cloud computing platform.

Problems solved by technology

In the networked system of multi-terminal computers and intelligent electronic terminals, since the physical memory requirements of each terminal are very different when running applications, especially on computers with high-performance CPU and memory, for applications that require little memory, a large number of Physical memory is idle, resulting in waste of memory resources

However, when other terminals execute applications with large memory requirements, the available physical memory is extremely scarce, so terminals lacking physical memory have to use local disk paging files (virtual memory) to make up for the lack of physical memory

Although the capacity of the local disk, especially the mechanical hard disk, is huge compared to the physical memory, it can provide enough virtual memory for the application, but the data transmission speed of the local disk is much lower than the speed of the physical memory, which sacrifices the performance of the application
