Research And Implementation Of System Simulation Data Distributed Computing Environment

At present, system simulation data is calculated on one computer. System simulation data is used to evaluate the performance of the network system which supports transaction system. This requires real-time computing system simulation data, in order to demonstrate network equipment's load to users when transaction system is running. Simulation data is so much as it is difficult of meeting real-time interaction to users when it is on one computer. It is necessary to connect different resources which are scattered on the internet into integrated one with the distributed computing technology. The new one will accomplish computing tasks together.Distributed computation using free resource on the network has been an important way of high-performance computation. It is more convenient than one computer to solve complex problems with providing better performance-price ratio. It analyzes system simulation data in thesis In view of the characteristics of system simulation data, such as real-time, the amount of computation, low processing speed of one computer, it adopts a three-layer structure based on the Master-Worker. In the realization of technology, it adopts Web Services in thesis. The computation application of system simulation data is deployed as a computation Web Services on the Worker.Firstly, it introduces the frameworks and the function of each module in thesis. Because it is a task which needs a long time to run, checkpoint function is adopted in order to avoid a great loss caused by one compute node's failure. Secondly, job assignment algorithms in the system are researched and an improved ant colony optimization is introduced which means that more tasks are assigned to high-performance computer and less tasks are assigned to low-performance computer and it will reduce the computing time by this way.
