But since you brought up the speed of execution, I did a search and came across this page where they tested different fortran compilers: The intel fortran (as you mentioned in your first post) is the fastest under windows 10 and i7 of all the compilers on average by about 50--100.I tried Microsoft Fortran Powerstation but found it erroneous.
Microsoft Visual Studio Fortran Compiler For Windows For Free Log InJoin for free Log in Most recent answer 12th Jan, 2021 Yukun Yang Shaanxi Normal University Both gfortran and ifort are not bad.
Cite All Answers (12) 21st Apr, 2017 Farshid Mossaiby University of Isfahan Hi, Check out GFortran for Windows if you want something free, otherwise Intel Fortran compiler can be a good option. Cite 23rd Apr, 2017 Thawatchai Chomsiri Mahasarakham University Let me check on that. Cite 25th Apr, 2017 Bilal Shafique The Ohio State University Y. Azizi please share the download link for MSDEV. Thanks. Thanks all others for their help. Cite 1st Mar, 2019 Farshid Mossaiby University of Isfahan Cite 4th Jul, 2020 Alan Kleinman I use gfortran and use the Code::Blocks IDE on Windows 8 and it runs very well. You can find info on this IDE and where to download it here: And there are several videos on YouTube that are very helpful in setting up the Code::Blocks IDE and the fortran compiler. Whats really nice about this compiler and IDE is that if you are on a limited budget, it is free. Regards, Alan Cite 1 Recommendation 4th Jul, 2020 Farshid Mossaiby University of Isfahan Alan Kleinman thanks; I had pointed it out already, but I should add that my experience shows that it is rather slow. Microsoft Visual Studio Fortran Compiler For Windows Windows 10 And WantIf you have Windows 10 and want something both free and high-performance, I would suggest installing Ubuntu (or other distributions available on Microsoft Store) on Windows via WSL (see below for link) and installing gfortran or gccg or virtually anything else you have on a native Linux distribution and enjoy the performance. Microsoft Visual Studio Fortran Compiler For Windows Code And II had a C code and I did my best to optimize it for my i7 laptop, but just adding a -marchnative command line option outperformed the mighty Visual Studio with all optimizations I have also been able to to run GUI application when using an X-server like Xming or packages as complex as Trilinos. One big bonus of this method is that you can run codes that would not normally compile or run on Windows, for example valgrind. WSL helps running native Linux binaries (yes, I mean ELF) on Windows. WSL (Windows Services for Linux): See Hope this helps Cite 4th Jul, 2020 Alan Kleinman If you run gfortran using code::blocks in its default mode with all the debug options turned on, the executable programs will run slowly. But if you go to the Setting tab, select Compiler., will open a window with checkboxes that allow you to optimize your program for speed, size, and even for the particular processor your computer uses (including your i7). My calculations dont take a lot of memory but use lots of clock cycles. Setting these flags allows the compiler to optimize for your particular application and use any math features your particular processor has. Whether there is a significant speed difference between gfortran and Microsofts version of fortran I dont know. What I suspect is that the speed of execution depends a lot on your compiler settings. And I cant comment on the advantages of disadvantages of the gnu C and C and microsoft versions of those languages because I dont program in those languages.
