摘要

Vienna Fortran 90是Fortran 90的语言扩展,它使用户能够仅使用全局数据引用为分布式内存多处理器编写程序。在这样的系统上,软件的性能受到数据分发给处理器的方式的深刻影响。因此,Vienna Fortran 90为用户提供了广泛的将数据映射到处理器的工具。它结合了共享内存编程范例的优点和对程序中那些对效率影响最大的方面进行显式用户控制的机制。本文介绍了Vienna Fortran 90的主要特点,并给出了它们的使用实例。

Vienna Fortran 90
Vienna Fortran 90 is a language extension of Fortran 90 which enables the user to write programs for distributed memory multiprocessors using global data references only. Performance of software on such systems is profoundly influenced by the manner in which data is distributed to the processors. Hence, Vienna Fortran 90 provides the user with a wide range of facilities for the mapping of data to processors. It combines the advantages of the shared memory programming paradigm with mechanisms for explicit user control of those aspects of the program which have the greatest impact on efficiency. The paper presents the major features of Vienna Fortran 90 and gives examples of their use.<>
