Embodiment Construction

[0033] A method for assigning tasks to power system network clusters based on load balancing. First, the information system defines a task schedule according to the computing and communication performance of each processor in the system and the request task requirements; then the system performs static tasks based on the task schedule. Allocation; finally, combined with the actual operation of the system, collaborative scheduling and process migration are carried out to relieve bottleneck pressure and improve system efficiency; figure 1 It is a flow chart of task assignment of power system network cluster based on load balancing. Specific steps are as follows:

[0034] 1) When there are m processors p in the power system network cluster 1 ,p 2 ,...,p m and the system user submits n power service requests to be dispatched to the system, and the parallel task j 1 ,j 2 ,...,j n , the central power distribution information system calculates that n tasks to be scheduled have ...

Abstract

The invention discloses an electric system network cluster task allocation method based on load balancing. The method comprises the following steps that: according to computing and communication properties of each processor of the system and requirement of a requested task, an information system defines a time table of the task; then the system performs static allocation according to the time table based on the task; and finally the system performs co-scheduling and process migration according to an actual operating situation, so as to relieve the choke point pressure and improve the efficiency of the system. The method provided by the invention is an electric scheduling method based on a load balancing allocation algorithm, which is suitable for large-scale electric network.

Description

technical field [0001] The invention relates to a power network cluster system, in particular to a load balancing-based power system network cluster task distribution method. Background technique [0002] In the large-scale distributed network cluster of modern power system, when the information system handles the allocation of power resources, it should optimize the combination of parallel processors and reduce the processing time delay in the network to give full play to the ability of the distributed processor system to multiple service requests. Respond in time to maximize the efficiency of the entire system. [0003] In the modern large-scale power network cluster system, the network structure is becoming more and more complex, coupled with the complexity of the model and many operating factors, the allocation of resources requires a large-scale calculation. As far as the power system is concerned, if its network can serve as many users as possible at the same time, it...
