Scheduling model of distributed test supported node adjustment as needed

In distributed test system,there is poor processing capacity in adjusting test nodes dynamically and low testing efficiency.To solve the problem,a practical scheduling model of distributed test is proposed.This model describes the probability distribution of task reaching and processing with M/M/N queuing theory,gives the index of await processing intensity to dynamically adjust test nodes,and then,sets up a task scheduling model to realize the target of the shortest test time.The simulation results prove that the model can adjust the test nodes dynamically according the change of test requirements,apply simple and practical scheduling method to reduce the load of test nodes effectively,improve testing efficiency.
