Intel Fortran Compiler

Fortran is still the best way for developers seeking to deliver exceptional 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

Flexible Development Environment: Choose between the intuitive Visual Studio IDE or command-line interface for efficient development, building, debugging, and running applications. Visual Studio users 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 Intel® MPI Library, along with analysis tools for efficient development, creating an exceptional Fortran development environment with outstanding performance.
Broad Industry Standards Support: The Intel Fortran Compiler offers full support for Fortran 95, 2003, 2008, 2018, and partial 2023 language standards, including Coarrays, DO CONCURRENT, and more. It also supports OpenMP 4.0, 4.5, 5.0, 5.1, 5.2, and select OpenMP 6.0 for CPU and GPU offload, alongside older Fortran standards (FORTAN IV (Fortran-66), 77, and 90).
Boost Application Performance: Accelerate compute by utilizing hardware acceleration features with build-in compiler optimizations like vectorization. These optimizations exploit the ever-increasing core count and vector register width in Intel® processors using SIMD (single-instruction-multiple-data), AVX/AVX2/AVX512 (advanced vector extensions) parallelism, and more, significantly boosting Fortran application performance.

The Intel Fortran Compiler is part of the Intel® oneAPI HPC Toolkit, Intel® Fortran Essentials, and is available as a standalone download. It integrates seamlessly into Visual Studio, supporting productive development of multicore, and cluster-based systems built on Intel Architecture.
