摘　　要：在高性能计算机上,研究基于不同编译器的三维短波射线追踪计算。通过对三维短波射线追踪计算的分析,设计和实现了三维短波射线追踪串行计算软件和并行计算软件,分别在GCC编译器和PGI编译器中编译生成可执行文件,基于PGI编译器的运行时间明显优于基于GCC编译器的运行时间。The three dimensional short wave ray tracing computation based on different compilers is stud- ied in the high performance computer. The serial computation program and the parallel computation one for three dimensional short wave ray tracing are designed through the analysis of the three dimensional short wave ray tracing computation. The serial and the parallel computation programs are compiled and made the executable files by GCC compiler and PGI compiler. The executable file runtime based on PGI compiler is much shorter than that based on GCC compiler.
