Intel® Fortran Compiler Classic and Intel® Fortran Compiler Introduction
Unless specified otherwise, assume the information in this document applies to all supported architectures and all operating systems.
Architecture Support
The compiler supports Intel® 64 architecture.
OS Support
Compiler applications can run on the following operating systems:
- Linux operating systems for Intel® 64 architecture-based systems.
- Windows operating systems for Intel® 64 architecture-based systems.
- macOS operating systems for Intel® 64 architecture-based systems.
NOTE:macOS is only available for the ifort compiler.
You can use the compiler in the command-line or in a supported Integrated Development Environment (IDE):
- Microsoft Visual Studio* (Windows only)
The Intel Fortran Compiler (ifx) is a new compiler based on the Intel Fortran Compiler Classic (ifort) front-end and runtime libraries, using LLVM back-end technology. At this time, ifx supports features of the Fortran 95 language, OpenMP* 5.0 Version TR4 and some OpenMP Version 5.1 directives and offloading features. ifx is binary (.o/.obj) and module (.mod) file compatible; binaries and libraries generated with ifort can be linked with binaries and libraries built with ifx, and .mod files generated with one compiler can be used by the other. Both compilers use the ifort runtime libraries. ifx supports GPU offloading, which ifort does not support. Fortran users that are uninterested in GPU offloading should continue to use ifort.
Standards Support
The compiler uses the latest standards including Fortran 2003, Fortran2018 and OpenMP 5.0 and 5.1 for GPU offload. Refer to the Conformance, Compatibility, and Fortran Features for more information.
Feature Requirements
This table lists dependent features and their corresponding required products. For certain compiler options, the compilation may fail if the option is specified but the required product is not installed. In this case, remove the option from the command line and recompile.
Feature |
Requirement |
---|---|
-mkl, -qmkl, -qmkl-ilp64, /Qmkl and /Qmkl-ilp64 options |
|
Thread Checking |
Intel® Inspector install. |
Trace Analyzing and Collecting |
Intel® Trace Analyzer and Collector install. Compiler options related to this feature may require a set-up script. For further information, see the product documentation. |
