Intel Fortran Compiler

Fortran is still the best way to deliver performance in computationally intensive applications. And Intel’s Fortran Compiler is built on a long history of generating optimized code supporting industry standards while taking advantage of built-in technology for the latest Intel® Xeon® Scalable processors and Intel® Core™ Ultra processors. Staying aligned with Intel's evolving and diverse architectures, the Intel® Fortran Compiler supports offload to Intel® GPUs for additional performance. In addition to great standards support, Intel Fortran offers productive tools, compiler directives, and compiler options that enable you to take advantage of ever increasing processor core counts and vector register widths available in Intel processors as well as offloading to GPUs. Build robust and easier to maintain applications using LLVM Sanitizers. And it works with Visual Studio, the industry standard in Windows application development, and can be used from the command line as well.

Features & Benefits

Visual Studio or command-line: your choice. Efficiently develop, build, debug and run from the familiar Visual Studio IDE, or build and run from the command line. If you use Visual Studio, you can build mixed-language applications with C++, Visual Basic, C# and more. Intel Fortran development support is broad and includes performance libraries such as Intel® oneAPI Math Kernel Library and analysis tools to support efficient development. It all adds up to a great Fortran development environment with outstanding performance.
Broad support for industry standards: Intel Fortran Compiler offers full Fortran 95, 2003, 2008, 2018, and initial 2023 language support, including Coarrays, DO CONCURRENT, and more. The compiler also supports OpenMP 4.0, 4.5, 5.0, 5.1, 5.2, and select OpenMP 6.0 for CPU and GPU offload, and older Fortran standards (FORTAN IV (Fortran-66), 77 and 90).
Boost application performance: Accelerate compute by leveraging hardware acceleration features with build-in compiler optimizations such as vectorization that utilizes the ever-increasing core count and vector register width in Intel® processors with SIMD (single-instruction-multiple-data), AVX/AVX2/AVX512 (advanced vector extensions) parallelism, and more to boost Fortran application performance.

The Intel Fortran compilers are included in the Intel® HPC Toolkit, Intel® Fortran Essentials and available as a standalone download. The compiler for Windows integrates seamlessly into Visual Studio supporting productive development of multicore, and cluster-based systems built on Intel Architecture.
