Abstract: This paper presents the design and implementation of the co-array Fortran(CAF)compiler based on GNU Fortran compiler. The CAF compiler translates CAF into Fortran 90 plus calls to runtime library. Typical tests are performed and the results show that CAF has better scalability. CAF gains better performance than OpenMP due to the explicit control on shared data distribution.

Key words: co-array Fortran(CAF), image, source-to-source translation

摘要： 基于GUN Fortran编译器，设计并实现了co-array Fortran(CAF)编译器。通过源到源的转换将CAF代码转换为带有运行库调用的Fortran 90程序。典型用例的测试表明，CAF具有较好的可编程性，且CAF程序通过对数据分布的显式控制可获得比OpenMP程序更为高效的执行性能。
