利用高性能Fortran(HPF)对三维全电磁粒子(PIC)程序TRISTAN(TriDimensionStanford)程序进行了并行化，并将其作为一台RPM(Real Parallel Machine)并行化。在仿真中，将模拟域分解为一维空间，每个子域中的粒子数据和场数据都分布在各个处理器上。相邻子域都需要子域上的粒子和场数据，因此子域之间的通信是不可避免的。使用HPF的模拟结果表明，HPF通信在大规模科学计算中具有很好的应用前景，例如3D粒子模拟。
A three-dimensional full electromagnetic particle-in-cell (PIC) code, TRISTAN (Tridimensional Stanford) code, has been parallelized using High Performance Fortran (HPF) as a RPM (Real Parallel Machine). In the simulation, the simulation domains are decomposed in one-dimension, and both the particle and field data located in each domain that we call the sub-domain are distributed on each processors. Both the particle and field data on a sub-domain is needed by the neighbor sub-domains and thus communications between the sub-domains are inevitable. Our simulation results using HPF exhibits the promising applicability of the HPF communications to a large scale scientific computing such as 3D particle simulations.
