Abstract

The invention discloses a dynamic task scheduling method under a cloud computing platform environment. Queuing processing is carried out on tasks by means of a queuing theory at first, quasi-optimal configuration of computing resources distributed by different virtual machines on various nodes in a cluster is searched out by means of an immune clone selection strategy in a manual immunity theory, reasonable configuration is carried out on the computing resources in the cluster, then antibody genes are regulated by means of load balancing, and therefore the configuration of the resources of the cluster can meet requirements for task processing. The invention discloses a dynamic task scheduling device under the cloud computing platform environment, wherein the dynamic task scheduling device comprises an affinity computing module, a judgment module, a determination module and an antibody relation module. According to the dynamic task scheduling method and device under the cloud computing platform environment, dynamic changing and virtualized environments of a cloud platform can be adapted, the optimal configuration is rapidly searched out, and the utilization rate of the resources of the cluster is improved.

Description

technical field [0001] The present invention relates to the field of software technology, in particular to a method and device for dynamic task scheduling in a cloud computing platform environment. Background technique [0002] For heterogeneous distributed systems, the heterogeneity of hardware, operating systems, programming, and communication networks that make up the system leads to great differences in scheduling strategies. There are a large number of task scheduling methods in the prior art, which are mainly divided into Two types: static scheduling and dynamic scheduling. [0003] However, none of the existing scheduling methods has been proven to be optimal, for example, task scheduling methods based on multi-objective optimization genetic algorithm and evolutionary programming, the goal of which is to minimize the scheduling length and maximize the reliability, both of which It is contradictory, and the execution speed and reliability are inversely proportional; b...
