Abstract：Task allocation is one of the key factors to influence performance of cluster system ,which affects load balan-cing and resources utilization of cluster system .In dynamic three-dimensional drawing of airport noise isoline ,the drawing ac-curacy and noise computational complexity depends on grid spacing size .In this process ,how to allocate the noise computing tasks for the dynamic three-dimensional drawing of airport noise isoline to different server nodes in the cluster system and dy-namically control the grid spacing size is the important steps to increase the resources utilization of cluster system ,shorten the average response time and improve the accuracy of drawing noise isoline .In order to achieve these purposes ,this paper analyzes the environmental factors of area around the airport and distribution character of airport noise ,establishes relation-ship between the noise computation and the load of server node ,and then a task allocation model for dynamic three-dimen-sional drawing of airport noise isoline is proposed .The model is solved by genetic algorithm .The simulation results show that the proposed method allocates tasks balanced and makes full use of system resources ,shorten response time ,and finally a-chieve the real-time computing requirements for dynamic three-dimensional drawing of airport noise isoline .
