| 英文摘要 | This paper provides that when the beam current increases to a certain level, the number of ions must be increased and the space charge effect must be added in accelerator physics in order to gain high precise status of ions. It's needed high performance computing to complete this work which needs TFLOPS level capability. So, a PC cluster based on Beowulf architecture and MPI2 was constructed, we put forward a parallel algorithm of divides and conquer according the mapping model of parallel problem, and we accomplished the simulation application of ions trajectory. In the end, we tested the application on different ions' simulation scale from 1.0E+4 to 1.0E+6. Experimental results show that optimized parallel algorithm gets 1.12 similar to 2.03 times on average speedup under the premise of guarantee accuracy. The best speedup is 2.52 when the number of ion is 1.0E+6 and the loop times is 1000. The simulation computation time is one third of be-fore. The success transplantation of ion parallel simulation software shows the superiority of the parallel computing and the validity of PC cluster. Additionally, it may be a good reference to other applications. |
