摘　　要：首次在Fortran语言中引入事务存储,对OpenMP Fortran API进行了扩展,以源到源转换的方式实现了FortranTM编译器原型。针对软件事务存储实现的特点,扩展了EXCLUDED和SCHEDULE指导命令子句,以便为程序员提供性能调整优化API。测试结果表明FortranTM API编程便利,具有良好的性能。OpenMP Fortran directive APIs were extended to support transactional memory.This is the first time to introduce TM into Fortran language.The source-to-source translation method was involved in the compiler prototype named FortranTM.EXCLUDED clause was introduced and SCHEDULE clause was extended with transaction size parameter.Experiment results show that FortranTM interfaces facilitate transactional programming and provide impressive performance profits.

关 键 词：源到源转换 事务存储 FortranTM
