Abstract

The invention discloses a realization method for NUMA (Non-Uniform Memory Access) structure based on distributed hardware-assisted memory virtualization. The method comprises the following four steps: step one, preparation stage; step two, normal work stage; step three, NUMA processing local request stage; and step four, NUMA processing remote request stage. The invention adopts the latest hardware-assisted memory virtualization technology and the distributed shared storage algorithm, provides a NUMA-structure shared single physical address space, and realizes the transparent and unified management to the multi-host memory resource by a guest operation system, so as to reduce the complexity of the application programming and increase the usability of system resource. Furthermore, the invention has the advantages of favorable use and development prospects.

Description

(1) Technical field

[0001] The present invention utilizes the latest hardware virtualization technology and adopts the internationally used distributed shared storage algorithm to integrate memory resources. It relates to memory virtualization in computer virtualization technology and distributed shared storage in distributed systems, especially An implementation method of non-uniform memory access (NUMA) structure based on distributed memory virtualization. It belongs to the field of computer technology. (2) Background technology

[0002] As early as the late 1960s and early 1970s, IBM Corporation implemented a commercial virtual machine (Virtual Machine, VM) on a mainframe. A virtual machine can be regarded as a complete computer system running in a completely isolated environment with complete hardware system functions through software simulation or hardware assistance. The classic virtual machine implementation is accomplished by means of a virtual machine monitor (Vir...
