Temperature prediction system and method for PCIe chip of server

Abstract

The invention provides a temperature prediction method for a PCIe chip of a server, and the method comprises the steps: defining a temperature prediction model for the PCIe chip through employing a gating circulation unit of a recurrent neural network, and enabling the temperature prediction model to comprise an input end and an output end, training data of the temperature prediction model are collected according to response changes among a plurality of control variables, and the temperature prediction model is trained by using the training data at the input end, so that a training result close to the measured temperature of the PCIe chip is obtained from the output end; evaluating the training result to obtain a plurality of features which can best reflect the temperature change of the PCIe chip, performing error analysis on the training result to obtain a group of key features from the plurality of features, and forming a temperature predictor according to the key features and the temperature prediction model, and generating, by the temperature predictor, a predicted temperature of the PCIe chip. The temperature prediction method can solve the problem that the chip on the PCIe card cannot return the temperature value.

Description

technical field [0001] The present invention relates to a method for predicting server temperature, in particular to a method for predicting server temperature using a neural network model. Background technique [0002] The ability of the server to dissipate heat directly affects the performance and stability of the server. Therefore, the server is equipped with a management chip (baseboard management controller, BMC) that manages the operating environment of the server. Information including power supply, voltage, temperature, fan speed, etc., is handled by the BMC. . After reading the temperature of each component, the BMC will control the fan speed of the server according to various conditions, so that it can dissipate heat in time. [0003] Most components inside the server, such as central processing unit (CPU), memory (DIMM), etc., can return their own temperature to the management chip. But many high-speed serial computer bus PCIe (PCI express) cards have their own ...
