What are the functions of NUMA? (Multiple choice)

• A.Topology presentation; the NUMA structure can be recognized inside the virtual machine, so the Guest Os can optimize the performance of the existing NUMA structure, but the application program in the VN cannot be optimized for the presented NUMA structure.
• B.Load balancing: In the scheduling process, consider the relationship between CPU and memory, as well as the corresponding relationship between vNode and physical Node, to maximize vCPU access to local memory,
• C.Dynamic migration, when the affinity between vCPU and physical Node changes, trigger its corresponding vNode memory to migrate.
• D.Initial placement: According to the RUMA topology of the virtual machine, select the physical Node to place the VCPU and memory, so that the relationship between the VCPU and the memory in the vNode is consistent with the physical reality.
