Abstract

The invention discloses a cloud task scheduling method based on a phagocytosis particle swarm genetic hybrid algorithm. Aiming at the task scheduling problem in the cloud environment, the updating method of position and speed in the standard particle swarm algorithm is changed, and the fitness function and the load balancing standard deviation are used to pair Each generation of particle swarms is divided into primary and secondary divisions, and the final divided particle sub-populations are subjected to phagocytosis mutation and cross-mutation operations respectively, and the scheduling scheme of cloud tasks is obtained. Through simulation experiments, the cloud task scheduling method proposed in the present invention is compared with several other existing cloud task scheduling methods. The results show that the method in the present invention significantly improves the overall completion time of cloud tasks and has higher convergence. The accuracy proves the effectiveness of the cloud task scheduling method based on the phagocytosis particle swarm genetic hybrid algorithm in the present invention.

Description

technical field

[0001] The invention relates to the field of cloud technology, in particular to a cloud task scheduling method based on a phagocytosis-based particle swarm genetic hybrid algorithm. Background technique

[0002] Cloud computing is defined as an information technology source and delivery model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) Management work or service provider interactions are quickly provided and released. The delivery models of cloud computing are divided into three categories, namely software as a service (SaaS), platform as a service (PaaS) and infrastructure as a service (IaaS).

[0003] As an emerging technology, cloud computing is widely used by companies and enterprises because of its great commercial value. It rationally utilizes and allocates various resources provided by the cloud environment, effectively schedules m...
