Embodiment Construction

[0027] The task scheduling method in the cloud computing environment of the present invention will be described in detail below with reference to the drawings and embodiments, but the present invention is not limited to the following embodiments.

[0028] The methods of the following embodiments run in a cloud computing environment, and the cloud computing environment mainly includes three parts structurally: a task scheduler, a data center node, and a computing node. Computing nodes can be composed of one or more subnets that provide different application services, and each application subnet is composed of multiple hosts, virtual machines, workstations or PCs, and is responsible for processing tasks assigned by the task scheduler. Computing nodes are not only responsible for executing tasks, but also send the status of processing tasks to data center nodes in real time, and report their own health status regularly. The task scheduler is the core component of the cloud comput...

Abstract

The invention discloses a task scheduling method under a cloud computing environment, and belongs to the technical field of computer application. The method of the invention comprises the following steps that: computer nodes register node information from a data center node; the computer nodes transmit health states thereof to a task scheduler through a health state reporting mechanism; the task scheduler allocates tasks to the computer nodes according to the node information, wherein during allocation, the difference between the computer nodes is not considered; computer nodes report the completion of the task to the data center node after each task is completed; the task scheduler allocates a new task to balance the task load between the computer nodes according to the task completion condition of each computer node; the data center node deletes the node information thereof when an abnormal computer node is found, and reallocates the task which is not completed by the node and serves as the new task; and the task scheduler recovers the task which is not completed within a specified time threshold value and reallocates the task as the new task. By the method, the safety for the task allocation under the cloud computing environment can be improved, and the throughput of the task scheduling is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of computer applications, and relates to task scheduling technology in distributed computing, in particular to a task scheduling method in a cloud computing environment. Background technique [0002] With the development of technologies such as multi-core processors, virtualization, distributed storage, broadband Internet, and automated management, a new computing model - cloud computing has emerged. The basic idea of ​​cloud computing is to organize huge computing resources to provide powerful computing or transaction processing capabilities. The entire cloud computing is a dynamic computing system that provides a hosted application program environment that can be dynamically deployed, dynamically allocated, re-allocated computing resources, and real-time monitoring of resource usage. Cloud computing usually has a distributed infrastructure, and can monitor this distributed system in real time to achieve e...
