Embodiment Construction

[0039] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0040] In view of the problems existing in the prior art, the method for allocating virtual network resources in the embodiments of the present application adopts a combination of the para-virtualization technology and the single-root input-output virtualization technology (SR-IOV, Single-Root I / O Virtualization) to optimize Network, by default, each virtual machine is assigned a para-virtualized virtual network card, and a single-root input and output virtualized virtual device (VF, Virtual Function) is only assigned to the critical path (CriticalPath) node after the m...

Abstract

The invention relates to a virtual network resource allocation method and system, and an electronic device. The method comprises the following steps: step a: generating a task map according to the network information of all virtual machines on a physical machine, and dividing the task map by using a multilevel map partitioning algorithm to obtain k mutually disjoint divided sub-sets; step b: calculating a critical path with the longest completion time in the divided sub-sets to obtain the virtual machine located in a critical path node; and step c: allocating a single input and output virtualized virtual device for the virtual machine located in the critical path node. According to the virtual network resource allocation method and system provided by the invention, the network is optimizedin a manner of combining the para-virtualization technology and the single single input and output virtualization technology, it is defaulted that each virtual machine is allocated with a para-virtualized virtual network card and the single input and output virtualized virtual device is only allocated with the virtual machine located in the critical path node after the multilevel map division, sothat the purpose of improving the overall network bandwidth utilization rate and shortening the overall execution time of the parallel applications is achieved.

Description

technical field [0001] The present application belongs to the technical field of computer virtualization, and in particular relates to a virtual network resource allocation method, system and electronic device. Background technique [0002] Due to the continuous reduction of computer hardware costs and the continuous enhancement of the computing power of a single computer in recent years, parallel computing has become more and more popular and widely accepted. At the same time, in order to efficiently utilize data center resources, virtualization technology is often used to improve the resource utilization rate of the data center. The so-called virtualization technology refers to the technology that can run multiple virtual machines on one physical machine, and the virtual machine is almost indistinguishable from the physical machine in the eyes of users, application software and even the operating system. Although this can greatly improve resource utilization, it also lead...
