如何从Freetran的下一行继续执行OpenMP指令? [英] How to continue an OpenMP directive on the next line in free-from Fortran?

问题描述

我有一行Fortran代码，例如

I have a line of a Fortran code, e.g.,

    !$omp do private(aa, bb, cc) schedule(dynamic) reduction(+:alpha, beta, gamma) 

假设此行包含多个参数，并且长度超过132个字符，gfortran将导致错误消息.我试图使用& 打破常规.但是我不确定如何开始下一行.在其他情况下，直接在没有！的情况下开始下一行会导致 Error:OpenMP变量列表中(1)的语法错误.

Suppose this line contains several arguments and the length exceeds 132 characters, gfortran will lead to error message. I tried to use & to break the line. But I am not sure how to start the next line. As other case, directly start the next line without ! leads to Error: Syntax error in OpenMP variable list at (1).

如何打破omp行的132个字符的限制?

How to break the 132 characters limit for omp line?

推荐答案

您可以通过以& 结尾并以 $ omp 开头的换行符来编写多行omp语句.

You can write multiline omp statements by ending with & and staring a newline with $omp.

示例

!$omp do private(aa, bb, cc) &
!$omp schedule(dynamic)      &
!$omp reduction(+:alpha, beta, gamma) 
...
!$omp end do
