Problems solved by technology

According to the survey, the utilization rate of memory and other resources of well-known cloud computing platform suppliers at home and abroad is less than 40%.
Some virtual machines tend to have more free memory than used memory over a period of time, while other virtual machines may run out of memory

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below through specific embodiments and accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] The invention discloses a method for extracting memory access features of a virtual machine on the Shenwei architecture. The realization principle of the whole mechanism of the method is as follows: figure 1 . The memory access feature extraction method can be specifically divided into three parts: the "set-interrupt" method, the "memory access failure rate curve" construction method, and the "hot page set" mechanism.

[0034] 1. "Set-interrupt" method

[0035] In order to calculate the working set size, the system needs to obtain the memory access sequence of the virtual machine application. In a virtua...

Abstract

The invention discloses a method and system for extracting memory access features of a virtual machine on the Shenwei architecture, which obtains virtual The working set size of the virtual machine is obtained by analyzing the reuse distance distribution of the memory access sequence of the machine, the memory page fault rate, and the page fault rate curve of the memory access memory. The present invention realizes the dynamic memory access feature extraction technology for the first time on the Shenwei platform, successfully draws the high-precision memory loss rate curve and calculates the accurate working set size, which is the next step for effectively multi-virtual machines according to the working set size Dynamic allocation of memory provides basic conditions to improve memory utilization.

Description

technical field [0001] The invention relates to the field of server memory virtualization optimization, in particular to a method and system for extracting memory access features of a virtual machine on a Shenwei architecture. [0002] technical background [0003] As one of the representatives of domestic CPUs, the Shenwei architecture CPU is already a relatively mature solution. Shenwei servers have been applied to many application fields in China, especially the key fields of the Chinese government and related organizations. As a domestic CPU architecture with completely independent property rights, Shenwei is developed and managed under the control of the state, so it can well guarantee the security of the system and is suitable for a variety of computer applications. Shenwei architecture servers will participate in more high-trust and high-security fields in the future, such as cloud data storage, large-scale data processing, cloud computing, etc. However, compared wit...
