Problems solved by technology

Cloud simulation applications are deployed on virtual machines. For different application services, when performing co-simulation jobs, the dynamic allocation of virtual machines for simulation applications is suitable for closed-loop queuing networks. When executing batch jobs and interactive jobs, virtual machines for simulation applications The dynamic provisioning is suitable for the open-loop queuing network, and only using a single queuing network cannot fully describe the simulation application service situation

Abstract

The invention discloses a cloud simulation task scheduling method based on a hybrid queuing network. The method includes calculating a resource quantity required by each of the plurality of cloud simulation tasks; Prioritizing the plurality of cloud simulation tasks according to the resource amount of each cloud simulation task; constructing A plurality of sub-queues, and allocating a plurality ofcloud simulation tasks to the plurality of sub-queues according to the request entry time of the plurality of cloud simulation tasks and the number of cloud simulation tasks that each sub-queue can bear, so as to provide an optimized cloud simulation task scheduling method and improve the processing efficiency of the cloud simulation tasks.

Description

technical field [0001] The invention relates to the technical field of cloud simulation task scheduling. More specifically, it relates to a cloud simulation task scheduling method based on a hybrid queuing network. Background technique [0002] In recent years, researchers have done a lot of research on resource scheduling in the cloud environment, mainly including the following research directions: research on resource allocation and scheduling to reduce energy consumption of data centers in cloud computing environments; to improve system resource utilization Resource management and scheduling research based on the target rate; research on cloud resource management model based on economics and other related research. However, these studies are all based on the premise of rational and effective use of current resources, without considering the entry and exit mechanisms of user tasks. [0003] The queuing network studies the various states that a system presents when it pro...
