Abstract

The invention discloses a cloud workflow virtual machine configuration and task scheduling collaborative optimization method, comprising the following steps: acquiring information required for executing optimization; calculating a hierarchical value of the task; initializing a contemporary population; decoding, improving and calculating a fitness value; performing independent evolution on a plurality of sub-populations, and timely performing communication among the sub-populations; and until a termination condition is satisfied, outputting an execution optimization result. Compared with a traditional method, the cloud workflow virtual machine configuration and task scheduling collaborative optimization method adopts the methods and strategies based on topological sorting and continuous biased coding, initial individual generation based on hierarchy and benefit ratio, serial individual decoding based on an insertion mode, forward and backward individual decoding and improvement, multi-population coordinated evolution and the like, can realize integrated collaborative optimization of resource allocation and task scheduling, and meanwhile can effectively improve the overall efficiencyof the algorithm.

Description

technical field [0001] The present invention relates to the fields of computer technology, information technology and system engineering, in particular to a cloud workflow execution optimization method, and more specifically, to a cloud workflow virtual machine configuration and task scheduling collaborative optimization method. Background technique [0002] Workflow under the cloud computing environment, referred to as "cloud workflow", is the integration of cloud computing and workflow-related technologies. Management, supply chain management and health care and other fields have broad application prospects. In cloud workflow, there are multiple types of computing resources and multiple tasks, and there are timing constraints between tasks. During execution, virtual machines are usually used as the smallest allocation unit of computing resources to receive and process these tasks. Cloud workflow execution or scheduling optimization refers to how to reasonably configure vi...
