介绍了ＦｏｒｔｒａｎＭ的基本概念和特点。ＦｏｒｔｒａｎＭ是一个支持分布式环境中并行计算的Ｆｏｒｔｒａｎ语言新成员，它在Ｆｏｒｔｒａｎ７７上扩充而成，不仅能支持数据并行程序设计，而且能支持任务并行程序设计。在重磁数据处理中，常常要进行大计算量的运算，如果采用并行计算方法，可以大大提高低档机器的运算能力，降低运算费用，缩短处理周期。本文用ＦｏｒｔｒａｎＭ把ＧＭＰＳ改造成并行计算系统ＧＭＰＳ－ＦＭ，经实际运行，效果良好，最后对测试结果作了分析。
Introduced the basic concepts and characteristics of FortranM. FortranM, a new Fortran language support for parallel computing in distributed environments, is augmented with Fortran77 to support not only data parallel programming but also task parallel programming. In the gravity and magnetic data processing, it is often necessary to carry out a large amount of calculations. If the parallel calculation method is used, the computing power of the low-grade machines can be greatly improved, the operation cost can be reduced, and the processing cycle can be shortened. In this paper, GMPS-FM is transformed into parallel computing system by FortranM, and the result is good after the actual operation. Finally, the test results are analyzed.
