Embodiment 1

[0060] A virtual machine-oriented CPU temperature prediction method, such as Figure 2-4 shown, including the following specific steps:

[0061] Node deployment step 110: build the experiment node 201, the environment temperature monitoring node 202 and the control node 203 respectively;

[0062] Data collection step 120: the experimental node (201) runs a certain number of configured virtual machines and sends the monitoring data of this node to the control node (203), while the ambient temperature monitoring node (202) collects the ambient temperature and sends it to the control node ( 203);

[0063] Temperature analysis step 130: analyzing the data collected by the management and control node 203, including feature extraction, extracting the physical machine configuration, virtual machine configuration, ambient temperature, initial CPU temperature of the experimental node 201, and CPU peak temperature as feature values, and using the feature values Input the training mode...

Abstract

The invention discloses a CPU temperature forecasting method for a virtual machine. The method comprises the steps of node deployment, data collection, temperature analysis and forecasting. Different running nodes comprising test nodes, environment temperature nodes and control nodes are built, a training model of a support vector machine is used for training output characteristics of the test nodes, a piecewise function is built on the basis of an output value of the training model, and a correct value is added to the piecewise function to obtain final forecasting data; in addition, the invention further discloses a CPU temperature forecasting device using the CPU temperature forecasting method for the virtual machine. The CPU temperature forecasting method and device for the virtual machine have the advantages of being high in forecasting precision, fast in modeling, small in calculated amount, and convenient to monitor remotely, supporting node separation and on-line forecasting, and having high application value.

Description

technical field [0001] The invention relates to a virtual machine-oriented CPU temperature prediction method and a virtual machine-oriented CPU temperature prediction device. Background technique [0002] With the advent of the era of cloud computing and big data, energy consumption and environmental issues in data centers have become increasingly prominent. Traditional energy-saving methods generally aim at reducing the computing energy consumption of nodes. In fact, due to the reliability requirements of equipment and the large temperature distribution of data center nodes, cooling energy consumption has become the most important part of data center energy consumption, and its energy consumption is close to 50% of all energy consumption. Therefore, establishing a temperature management system for data centers and comprehensively considering computing energy consumption and cooling energy consumption provide a new idea for energy saving. The temperature management of the ...
