Compilatore Fortran Intel®

Free Intel Visual Fortran for students!

Intel Fortran is now available under a free, non-commercial license for qualified students on Linux, OS X and WIndows. See for more details.

Note: If you don't already have a supported Microsoft Visuall Studio installed, you'll need to get one first as the student license doesn't include the VS Shell-based IDE. The free Visual Studio 2013 Community Edition will do.

OS X 10.9 Xcode 5 error ld: library not found for -lcrt1.10.6.o

Environment:  OS X 10.9 (Mavericks) and Xcode 5.0

Command line compilations/links fail with "ld: library not found for -lcrt1.10.6.o"

Affected compiler:  Intel Composer XE 2013 Update 1

Root cause:  Xcode 5.0 installation does not install all command line tools (include files, libraries, SDKs) need for the compiler to link user applications. 

Оптимизировали, оптимизировали, да не выоптимизировали!

Оптимизация? Конечно, каждый сталкивался с данной задачей при разработке своих, сколь-нибудь значительных, требующих определённых вычислений, приложений. При этом способов оптимизировать код существует огромное множество, и, как следствие, различных путей сделать это в автоматическом режиме с помощью опций компилятора. Вот здесь и возникает проблема – как выбрать то, что нужно нам и не запутаться?

New error in v16 for uddtio

I have just installed v16 and code which compiled fine with all the previous v16 betas, v15 and v14 now no longer compiles. I get the following error message on lines of code that use UDDTIO, e.g.

    subroutine dump_strsum(f)
        character(len=*), intent(in) :: f
        integer :: u
        write(u,'(dt)') strsum_data
    end subroutine dump_strsum


Error code 23 (returned by OpenValidateX) opening pdb Debug\vc140.pdb

I have just done a clean install of Visual Studio Community 2015 and Intel Parallel Studio XE Pro 2016 using default settings for both of them on a new computer running Windows 10 Pro 64bit. I'm getting "Error code 23 (returned by OpenValidateX) opening pdb Debug\vc140.pdb" on every Fortran file during the compile when I try to do a build. I don't have any old versions of VS or Intel Fortran installed on this computer.

I don't have this problem with the same project being built on a different computer running Windows 8, VS2010 and Intel Parallel Studio XE Pro 2015.
