They are designed to minimize stalls and to produce code that executes in the fewest possible number of cycles. Intel compilers are optimized for computer systems using processors that support Intel architectures. When used with Intel cluster tools (see the 'Description of Packaging' below) the compiler can also automatically generate Message Passing Interface calls for distributed memory multiprocessing from OpenMP directives. When used with the Intel HPC toolkit (see the 'Description of Packaging' below) the compiler can also automatically generate Message Passing Interface calls for distributed memory multiprocessing from OpenMP directives.įor more information on Fortran standards, a number or resources are available, such as the Wikipedia Fortran entry or the Fortran wiki page. The 2021 beta compiler focuses on OpenMP for GPU Offload. The 2021 release of the Classic compiler adds full Fortran support through the 2018 standard, full OpenMP* 4.5, and Initial Open MP 5.1 for CPU only. In 2020 the existing compiler was renamed “Intel Fortran Classic” (ifort) and a new Intel Fortran Compiler (beta) (ifx) supporting GPU offload was introduced. On macOS and Linux, it is known as Intel Fortran. On Windows, it is known as Intel Visual Fortran. A specific release of the compiler (11.1) remains available for development of Linux-based applications for IA-64 ( Itanium 2) processors. The compilers generate code for IA-32 and Intel 64 processors and certain non-Intel but compatible processors, such as certain AMD processors.
