Problems solved by technology

At present, there are mainly OpenStack solutions and VMware solutions for virtualized NUMA management, but the OpenStack solution completely relies on the user-specified NUMA structure and mapping strategy, and the VMware solution adopts the "NUMA affinity" strategy, which is not strictly bound. Both the performance of the system and the system itself are not good, and there are great restrictions on functions such as migration and hot addition
To sum up, these two solutions cannot be flexibly configured to build a reasonable NUMA structure for the virtual machine, resulting in a large loss of memory access performance and affecting the overall performance of the system

Abstract

The invention relates to a resource scheduling allocation method, a computer system and a super-fusion architecture system. The resource scheduling allocation method comprises the steps of determiningan overall configuration demand of a virtual NUMA structure corresponding to a virtual machine, wherein the overall configuration demand comprises sub-configuration demands of a virtual NUMA node, and the sub-configuration demands include a first configuration demand for a virtual CPU core and a second configuration demand for a virtual memory; determining overall resource availability of a physical NUMA structure, wherein the overall resource availability comprises sub-resource availability of a physical NUMA node, and the sub-resource availability includes first resource availability for aphysical CPU core and second resource availability for a physical memory; and based on the overall configuration demand and the overall resource availability, establishing a corresponding relationshipbetween the virtual NUMA node and the physical NUMA node. The resource scheduling allocation method realizes mapping and binding of the virtual NUMA structure and the physical NUMA structure, so thatphysical resources are reasonably allocated.

Description

technical field [0001] The present invention relates to the field of communication technology, and more specifically, it relates to a resource scheduling and allocation method, a computer system and a hyper-converged architecture system. Background technique [0002] Hyper-converged architecture refers to the use of software methods to realize and integrate computing, network, and storage functions on servers (especially x86 servers) to form a modular deployment unit, and interconnect the network through switching (constructed by standard commercial switches, etc.) Realize a cluster that can scale horizontally. [0003] At present, the multi-processor computer system structure is composed of a non-uniform memory access (Non Uniform Memory Access Architecture, NUMA) architecture. Under the NUMA architecture, the time for the processor to access the memory depends on the location of the memory. Usually, the processor accesses its local memory faster than the non-local memory....
