gfortran优化在运行时导致fortran do变量循环错误 、、、 我已经写了一个fortran例程,它使用了一些遗留的fortran 77代码来处理有限元。然而,对于特定的网格,当-O优化标志打开时,一个重要的do循环迭代器正在以某种方式被修改,尽管fortran理应禁止这样做。我使用gfortran4.5编译了这段代码,并启用了-fcheck=do运行时检查,...
6 – Subscripted Variables, the DATA Statement, and the Implied DO LoopThis chapter presents a different way of representing variables. In FORTRAN, each element is called a subscripted variable. Part of the name of a subscripted variable—the part that appears between the parentheses—can be...

Also, I noticed that the use of IF-ELSEIF construct is noticeably less efficient than using multiple IF statements in a DO-loop. Is this observation correct? I am using Intel Fortran compiler 2015, with O2 optimization flag. Thanks you in advance, Translate Tags: Intel® Fortran Compiler ...
A DO loop length evaluating part 4 calculates the DO loop length based on the initial value, the final- value and the increment value of the control variable contained in each DO loop. Then a DO loop length sorting part 5 sorts those obtained loop lengths in the order of larger values, ...
