Research Of Three-dimensional Paralleling Particle Simulation Technology On High-performance Computing Platform

Because of the research aspiration of Vacuum electronic devices,which contain complex electromagnetic and particle interactions,merely use analytic method hard to acquire the accurate result.Moreover,it is very expensive and time-consuming to design these devices experimentally.As the third path of vacuum electronic device research,particle-in-cell method is lower cost,visually and easy operation.It uses the modern computer to study the movement and interaction of charged particles in the electromagnetic field.However,electromagnetic PIC simulation needs huge computing resource.For example,a lot of simulation usually need take dozens of hours or hundreds of hours.Some even can't simulated due to computing resource constrain.Parallel computing is regarded as the best method to overcome this disadvantage.At present,the high-performance computing platform acquired great success in our country.In this paper,based on the investigation of the Milky Way high performance computing platform and the works of CHIPIC research team,a new CHIPIC3D adapted to the platform is developed.Moreover,some vacuum electronic devices are simulated by large-scale parallel computing of CHIPIC3D on the Milky Way high performance computing platform.The main research is as follows:1.Through the investigation of the Milky Way high performance computing platform,the logical structure of the Milky Way high performance computing platform,operating system and composition of the Milky Way resource scheduling system are acquired;the MPI parallel environment and operating are acquired.2.According to the non-graphical operation interface of the Milky Way high performance computer platform,we set up the Windows three-dimensional modeling module,Uinx/Linux large-scale parallel computing module and Windows digital visualization module to implement the CHIPIC3D adapted the high performance platform.Based on these,the development and testing environment for Windows 3D modeling and data visualization is built;according to the type and version of the operating system and parallel support library of the high performance computing platform,the Linux programming environment and a four node high performance cluster testing system based on Linux are built.3.The Windows 3D modeling module,Unix/Linux parallel computing module adapted to the Milky Way high performance computing platform and Windows data visualization module are analyzed?designed and developed respectively.And then,a complete CHIPIC3D consist of the three module above is realized.4.Use the developed CHIPIC3D to simulate the magnetically insulated line oscillator,the relativistic klystron oscillator,the relativistic backward wave oscillator and the 140 GHz traveling-wave tube by large-scale parallel computing on the Milky Way high performance computing platform.Analyze the experimental data.
