Embodiment Construction

[0040] combine Figures 1 to 6 , the realization of a kind of CPU resource scheduling method based on Xen system of the present invention is described as follows:

[0041] When implementing the algorithm, the main thing to consider is to classify the tasks run by DomainU. Since CPU-intensive and IO-intensive tasks have completely different demands on CPU resources, if the two types of tasks are treated the same as the Credit algorithm , it will cause IO-intensive tasks to often fail to obtain the small amount of CPU resources they need, resulting in high response latency of their tasks, which may basically reach twice the time slice size.

[0042] The algorithm determines the number and proportion of CPU-intensive and IO-intensive tasks in all tasks running in the global domain by obtaining the remaining credit status in the running queue of all vcpus on the global physical core and its state. The size of the time slice is adjusted by the ratio of CPU-intensive tasks and IO-int...

Abstract

A CPU resource scheduling method based on Xen system relates to the technical field of CPU resource scheduling. The present invention solves the problems that the existing CPU resource scheduling method cannot distinguish specific running tasks, and cannot be combined with a real-time running environment to adjust CPU resources. Use the vcpu queue as input data to train the RNN classification model; obtain the global queue information credit[] and pri[] of the Xen system, and then use the trained RNN classification model to train the global queue information credit[] and pri[ of the Xen system ] for classification; determine whether the above array is empty, if so, end, otherwise the classification result will update the q-table table through the Q-learning algorithm; use the current updated q-table table to adjust the time slice to complete the scheduling of CPU resources. Improve efficient utilization of resources and reduce energy consumption in cloud data centers.

Description

technical field [0001] The invention relates to a CPU resource scheduling method based on a Xen system, and relates to the technical field of CPU resource scheduling. Background technique [0002] In recent years, with the development and rise of cloud computing technology, virtualization technology has begun to appear in people's sight again. The purpose of virtualization technology is to virtualize physical resources. Through virtual machine monitor (Virtual MachineMonitor, VMM), the virtualized physical resources are reasonably allocated to multiple virtual machines for use, and to ensure that multiple virtual machines are independent of each other. , which do not affect the operation of their respective tasks. The current mainstream virtual machine architectures are: VMware's ESX, Microsoft's Hyper-V, open source Xen and KVM. With the expansion of the cloud computing environment, resulting in the continuous increase of energy consumption, resource scheduling is becomin...
