Description

technical field [0001] The present invention relates to the technical field of virtual machine resource management, in particular to a virtual resource management system and method based on heterogeneous multi-core topology perception. Background technique [0002] Current data center servers are basically equipped with multiple processors to provide powerful computing capabilities. For example, the Dell PowerEdge R730 server is equipped with two processor sockets, while the PowerEdge M830 is equipped with 4 processor sockets. These processors are organized into a non-uniform memory access (Non-Uniform Memory Access, NUMA) architecture to improve memory access bandwidth. Processors are connected to each other through an interconnect for data transfer and communication. However, different processor interconnection solutions provided by different processor manufacturers result in different interconnection topologies of different servers. For example, Intel processors are con...
