Embodiment Construction

[0030] In order to express the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The equipment environment condition that the present invention needs to satisfy sees figure 1 , the structure of distributed computing nodes in the cloud environment mainly includes a master control node (master node) and multiple computing nodes (sub-nodes). Computing nodes can be either physical machines or virtual machines, which are transparent to the master control node , the nodes are interconnected through the network. The master control node interacts with the computing node through remote procedure call (RPC). The main control node is mainly responsible for receiving the heartbeat information of computing nodes, and analyzing and feeding back to control the scheduling and execution of tasks; among them, the node anal...

Abstract

The invention provides a task-dynamic dispatching method under a distributed computation mode in a cloud computing environment, which comprises the following four steps: 1. a main node receives and analyzes heartbeat information of a subsidiary node; 2. the main node previously distributes the task according to a node state table and a task state table; 3. the subsidiary node demands the task from the main node; and 4. the main node distributes the task to the subsidiary node. The method firstly considers the resource demand of the task and the performance information of the nodes, and dynamically controls the distribution of the task under the condition that the requirement is met, so that the response speed of the work and the resource utilization of the nodes are improved. The method has wide practical value and application prospect in the technical field of the distributed computation in the cloud computing environment.

Description
