Intelligent configuration and load-aware scheduling for optimizing integrated host virtual resource

中文摘要英文摘要

针对边缘计算平台中因异构应用共存、动态负载频发引发的虚拟化资源配置不准确和调度效率低的问题,以列车融合主机为典型应用场景,提出一种基于智能化配置与负载感知调度的融合主机虚拟化资源联合优化方法.首先,通过量化分析融合主机典型应用的资源需求特征,构建了一种基于随机森林建模和二分查找法的资源配置预测模型,实现对虚拟化资源的精准前瞻性分配.其次,针对动态负载变化,设计了一种改进的遗传算法,该算法将虚拟化应用与物理CPU核心进行映射,并结合资源利用率与应用性能的多目标适应度函数,动态调整调度策略.实验结果表明,与传统优势资源公平(dominant resource fairness,DRF)算法相比,所提出的资源配置预测模型能提供优于人工初始化的配置参数,同时改进的遗传算法将CPU平均利用率从13.5%提升至22.07%,相对提升幅度达63.5%,目标函数值从0.035提升至0.204,提升约4.83倍,服务器总资源占用降低44%,有效节约了硬件成本与能耗开销.研究为边缘计算平台在高动态场景下的资源优化提供了通用方法,并以列车融合主机为例验证了其可行性,对智能边缘系统的构建具有普适参考价值.

Addressing the issues of inaccurate virtualized resource allocation and low scheduling efficiency caused by the coexistence of heterogeneous applications and frequent dynamic loads in edge computing platforms,a joint optimization method for virtualized resources of a converged host based on intelligent configuration and load-aware scheduling was proposed,using a train-related converged host as a typical application scenario.Firstly,by quantitatively analyzing the resource demand characteristics of typical applications of the converged host,a resource allocation prediction model based on random forest modeling and binary search method was constructed to achieve precise and forward-looking allocation of virtualized resources.Secondly,in response to dynamic load changes,an improved genetic algorithm was designed.This algorithm mapped virtualized applications to physical CPU cores and dynamically adjusted the scheduling strategy by combining a multi-objective fitness function that considers resource utilization and application performance.Experimental results showed that,compared to the traditional dominant resource fairness(DRF)algorithm,the resource allocation prediction model proposed provided configuration parameters superior to those initialized manually.Meanwhile,the improved genetic algorithm simultaneously increased the average CPU utilization from 13.5%to 22.07%,representing a relative increase of 63.5%.The objective function value increased from 0.035 to 0.204,a approximately 4.83-fold increase,reducing the total server resource consumption by 44%,and effectively saved hardware costs and energy consumption.The study provides a general method for resource optimization in edge computing platforms under highly dynamic scenarios,and verifies its feasibility using the train converged host as an example.It has universal reference value for the construction of intelligent edge systems.
