Abstract

The embodiment of the invention discloses a hot spot equalization control method and a related device. The above method includes: establishing a current hottest node set; predicting the hot memory pages to be accessed of each physical NUMA node in the current hottest node set; determining the hottest virtual machine; Migrate to an idle physical NUMA node. It can be seen that, in the embodiment of the present invention, the hot memory pages to be accessed on the physical machine are predicted, and the hot memory pages to be accessed owned by the hottest virtual machine are migrated. The predicted hot memory pages to be accessed are memory pages that may be frequently accessed in the future. After migrating them, the probability of overheating of a certain NUMA node in the future can be reduced to a certain extent, and hot spot balance control can be realized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a hotspot equalization control method and a related device. Background technique [0002] With the development of virtualization and cloud computing, virtual machines are widely deployed on non-uniform memory architecture (Non-uniform Memory Architecture, NUMA) physical machines (physical servers). [0003] A physical machine based on the NUMA architecture includes multiple physical processors and multiple memories. The aforementioned multiple physical processors and multiple memories can be divided into multiple groups (also called physical NUMA nodes). One or more virtual machines run on a physical NUMA node. [0004] In the implementation of the present invention, the inventors found that due to frequent access (mainly write operations) and other reasons for the business running by the virtual machine, some memory pages in the physical NUMA node memory will be...
