问题 I wish to change the working directory in a Fortran 90 code. Is it possible to do this in a non compiler-specific way? Here is my code: program change_directory integer :: ierr call system("mkdir -p myfolder/") !call system("cd myfolder/") !doesn't work ierr = chdir("myfolder") if (ierr.NE.0) then write(*,'(A)') "warning: change of directory unsuccessful" end if open(unit=33,file="myfile.txt",iostat=ierr) if (ierr.EQ.0) then write(unit=33,fmt='(A)') "Test message" close(unit=33) end if end

问题 I am trying to compile a simple C++/Fortran Mixed program but have linking issue. I am using Visual Studio 2013 Ultimate and Intel Visual Fortran Compiler XE 14. The program is very simple and is copied from somewhere from the net. It has one C++ file and one Fortran file The C++ file is: // Illustrate passing integer and floating point arrays // from C++ to Fortran #include <iostream> using namespace std; extern "C" { int __stdcall SUMIT(int *, int*); float __stdcall MEAN(float*, int*); }

问题 It seems to me the what is called a pure function in Fortran is not considered pure enough for those who use functional programming. So here is my question. Suppose I have the following code: MODULE basics IMPLICIT NONE INTEGER, PARAMETER :: dp = kind(1.0d0) REAL(dp), PARAMETER :: PI=3.1415926535897932_dp REAL(dp), PARAMETER :: earthEquatorialRadius=6378.137_dp END MODULE basics MODULE myFunctions USE basics IMPLICIT NONE PURE REAL(dp) FUNCTION sphericalArc(angleInRadians) REAL(dp),INTENT(IN)

问题 I have some fortran code compiled with intel fortran compiler ifort. When I do a profile test with gprof, I get that most of the time is used in IO operations, I think finding the end of the files, but I can no find any more documentation on this: index % time self children called name <spontaneous> [1] 20.6 0.07 0.00 _IO_wfile_seekoff [1] ----------------------------------------------- <spontaneous> [2] 20.6 0.07 0.00 sforcepf_ [2] ----------------------------------------------- <spontaneous

问题 I'm writing my code on CFD topic with Fortran. After discussing with some friends from computer science, they told me that one could speed up the computation time if one implements Structures of Arrays (SoA) instead of Arrays of Structures (AoS) on his/her code. There are many examples I've seen about this topic's implementation, but most of them are in C or C++.

问题 I'm trying to achieve in using f2py on windows 8, x64, with Intel Fortran Compiler. I've tried two things : 1) install via windows 64x installer. http://www.lfd.uci.edu/~gohlke/pythonlibs/ NumPy is correctly installed, but no compiler found when executing f2py -c --help-fcompiler I got : Fortran compilers found: Compilers available for this platform, but not found: --fcompiler=absoft Absoft Corp Fortran Compiler --fcompiler=compaqv DIGITAL or Compaq Visual Fortran Compil --fcompiler=g95 G95
