It is recommended to install the Intel ® oneAPI Base Toolkit first for full functionality. Please follow the steps to download the Intel ® oneAPI HPC Toolkit and follow the installation instructions. In this release, the ifx version number is 2022.0.0 and the ifort version number is 2021.5.0. Performance and Fortran Standard language improvements will be coming in ifx with each update release throughout 2022. ifx may or may not match performance of ifort compiled applications.

Both compilers use the the same runtime libraries.
#Runtime environment in compiler design notes mod#
mod files generated with one compiler can be used by the other (64-bit targets only). Binaries and libraries generated with ifort can be linked with binaries and libraries built with ifx, and. In this initial release ifx completely implements Fortran 77, Fortran90/95, Fortran 2003 (except parameterized derived types) and Fortran 2008 (except coarrays) language standards and OpenMP 4.5 and OpenMP 5.0/5.1 directives and offloading features. ifx is binary (.o/.obj) and module file (.mod) compatible. ifx is based on the Intel® Fortran Compiler Classic (ifort) frontend and runtime libraries, but uses LLVM backend compiler technology. Our latest compiler, the Intel® Fortran Compiler (ifx), is production-ready for CPUs and GPUs.

For calendar year 2022 ifort continues to be our best-in-class Fortran compiler for customers not needing GPU offload support. The OpenMP 5.0, 5.1 GPU offload features in ifx are not available in ifort. The Intel® Fortran Compiler (ifx) enables developers needing OpenMP* offload to Intel GPUs. The Intel® oneAPI product packages provide two Fortran compilers. Intel® Fortran Compiler Classic (ifort) provides best-in-class Fortran language features and performance for CPU. This document provides a summary of new and changed product features and includes notes about features and problems not described in the product documentation.
