Communication optimizing method for cluster server

The invention discloses a communication optimizing method for a cluster server. The cluster server comprises multiple processing servers in communication. According to the communication optimizing method, when any processing server receives a task to be processed, the processing server collects the resource usage data of other processing servers in the cluster server; then the processing server corresponding to the task to be processed is selected according to the resource usage data of each processing server; finally, the corresponding processing server is selected after the attribute of the task is judged. According to the method, the pressure condition of each server is collected through an exchange bus, data needing to be transmitted are distributed to the server with the lowest pressure to be processed according to the priority of the exchanged data, and then the purposes of balancing the loads of different cluster servers and improving task processing efficiency are realized.
