As of today Fortran is still one of the leading programming languages for high performance and scientific computing; on the other hand HPC and scientific computing are still a highly specialized niche and, as a result, not many user friendly tools are available for Fortran development.

On Linux many different, arguably better, alternatives are available. Various Fortran compilers are available, a comprehensive list is available on the web site of the Fortran Programming Language. Microsoft Visual Studio VS for now on is a complete and feature rich general purpose IDE; being general purpose it does not natively support Fortran development or other features which might be of interest in the context of scientific computing and, in particular, development of numerical analysis codes.

Fortunately though the integration with Intel compiler and diagnostics tools makes it a viable option for our use case. VS is closed source and commercial software, but the community edition is free to use for non commercial purpose with a Microsoft account, the minimal functional limitation of this edition are not of any relevance for our use case.

These tools are also available on Linux as separate applications, but on Windows they integrate in the IDE. It is important to follow the prescribed installation order to get out-of-the-box support. At this point creating a new project in VS an option for Fortran language should appear. Keep in mind that there is no difference between these choices a part from the file extension, all files are simply plain text files.

In this case the compilation is very simple: hitting Start should do it, if it does not there might be some error in the code. This case is again pretty simple: within the same project, Visual Studio automatically determines the dependencies and the right compile order. So we just press F5. If we want the modules to be accessible to more than one main program, we can compile them in a static library and link it to the main program. We can now create other projects for other main program, and link them against the library with the same procedure.

In this article I hopefully gave a complete introduction to the usage of Visual Studio and Intel Fortran Compiler aimed at numerical analysts and Fortran developers who need or want to work on Windows. I will continue to do my coding on Linux, as more powerful tools are freely available, many HPC centers, including the one at my University, ase Linux systems, and I have more control on what I am doing, instead of needing to look for mysterious options and learning funny file structures with their own lexicon.

Fortran compilers Various Fortran compilers are available, a comprehensive list is available on the web site of the Fortran Programming Language. Intel Fortran is natively available on all platforms; but on Windows is virtually the only free option, thanks to the integration with Visual Studio.

The Visual Studio IDE Microsoft Visual Studio VS for now on is a complete and feature rich general purpose IDE; being general purpose it does not natively support Fortran development or other features which might be of interest in the context of scientific computing and, in particular, development of numerical analysis codes.

Key features The key features that I found interesting are: Automatic determination of compilation order: on Linux I used the make utility to compile and link the various components of my code; on Windows, due to my poor knowledge of its shell and lack of basic tools, I was not able to use make.

This was the main reason I resorted to Visual Studio in the first place. Support for debugging, signally Execution pause Break point support Variable inspector Performance measurement During execution CPU and memory usage are monitored and the runtime is tracked The IDE integrates with Intel performance diagnostics tools VTune adn Advisor These tools are also available on Linux as separate applications, but on Windows they integrate in the IDE Key annoyances There is support for syntax highlighting, but absolutely no support for statement autocompletion There is no support for any kind of code exploration I suggest to write the code in a more feature rich text editor here are some very useful suggestions and use VS only for compilation and debugging.

At the end of the procedure, check that VS is installed on your system launching it. On the download page we suggest to select an Online installer. Launch the installer and follow the directions: Proceed with a default install all components are installed Be sure to check the box Microsoft Visual Studio in the Integrate IDE step At the end of the process close the installer. Checking the configuration At this point creating a new project in VS an option for Fortran language should appear.

We’re contemplating upgrading from Windows 7 to Windows Our old friend Visual Studio may not make the journey with us Is Visual Studio the best option? I don’t follow whether you are thinking of dropping ifort in favor of an IDE which may support gfortran.

We want to stick with Intel Fortran. We’re currently using version My understanding is that Visual Studio is no longer bundled with Intel Fortran. Was the decision to not bundle Visual Studio based on the availability of better options? Not exactly sure what you mean by this.

Have you reviewed all the information online at Intel Fortran site? As you would know, Visual Studio is a product by Microsoft so you would need to license it separately.

What all are your needs and requirements? That is what would guide you best in terms of your IDE choice. That understanding isn’t right – Microsoft Visual Studio Shell is still bundled with commercial licences of the Fortran compiler.

That shell edition lacks features that are present in the more complete editions of Visual Studio other languages, the resource compiler , but that shouldn’t be too different to whatever cut-down variant of Visual Studio was bundled back when Visual Studio was current.

Be sure to check the “rc. Moving Fortran projects from an older VS I think you’d expect that VS will give a message that it is updating the project and solution files. That works fine for me too. After updating a project to VS it is probably worth checking the project settings and compiling and linking options to confirm they are as you expect.

Does your situation qualify the terms for Visual Studio Community edition? IanH Black Belt. OK, my misunderstanding. Regards, Greg. Post Reply.
