Abstract

The invention discloses a virtual CPU scheduling method. The virtual CPU scheduling method comprises the following steps: determining a target virtual CPU according to a received virtual CPU scheduling instruction; determining a physical machine CPU set corresponding to the target virtual CPU; judging whether an alternative physical machine CPU of which the current load is smaller than the global average load exists in the physical machine CPU set or not; If yes, scheduling the target virtual CPU to an alternative physical machine CPU with the minimum current load in the physical machine CPU set; If not, scheduling the target virtual CPU to the physical machine CPU with the minimum global load. According to the method and the device, the load balancing among the CPUs of the physical machine can be realized, and the synchronization delay among the virtual CPUs is reduced. The invention furthermore discloses a virtual CPU scheduling apparatus, an electronic device and a storage medium, which have the above beneficial effects.

Description

Technical field [0001] The present application relates to the field of virtual machines, and in particular, to a dispatching method, apparatus, an electronic device, and a storage medium for a virtual CPU. Background technique [0002] With the development of cloud computing, more and more business migrate to the cloud. In a virtualization scenario, multi-threaded applications run in a virtual machine, so the synchronization delay of multi-threaded applications is affected by the degree of collaborative scheduling of multiple virtual CPUs in the virtual machine. [0003] In the relevant technique, multiple virtual CPUs of the same virtual machine typically increase the probability of a virtual CPU coordinated scheduling to different physical machine CPUs. However, the above-mentioned scheme of multiple virtual CPUs to different virtual machines to different physical machine CPUs can result in a large load difference between the physical machine CPU, affecting the overall computin...
