Intel® Fortran Compiler System Requirements

Publicado:09/24/2019   Última actualización:12/15/2020

Introduction

This document provides details about hardware, operating system, and software prerequisites for the Intel® Fortran Compiler for oneAPI. 

In order to gain all functionality and optimal performance with Intel® oneAPI we recommend installing both the Intel® oneAPI Base Toolkit AND the Intel® oneAPI HPC Toolkit. Both toolkits should be downloaded and installed for optimal performance and to obtain all available Intel Performance Libraries. Please refer to the Installation Guide for Intel® oneAPI Toolkits for obtaining and installing both toolkits.

Please see the Intel® Fortran Compiler for oneAPI Release Notes for additional information.

Hardware Requirements

  • CPU Processors
    • Intel® Core™ Processor family
    • Intel® Xeon® Processor family
    • Intel® Xeon® Scalable Performance processors
  • Accelerators (ifx only)
    • Intel® integrated graphics (GEN9) or greater. Also refer to wikipedia GEN9 for details.
  • 8GB of RAM recommended
  • 14GB free disk space for all features

Software Requirements

The Intel® Fortran compiler is included in the Intel® oneAPI HPC Toolkit which requires Intel® oneAPI Base Toolkit.

Linux* OS

  • Red Hat Enterprise Linux* 7.x, 8.x
  • CentOS* 7, 8
  • Ubuntu* 20.04 LTS
  • Fedora* 29
  • SuSE LINUX Enterprise Server* 12, 15 SP1
  • Debian* 9.0
  • For OpenMP TARGET (ifx only)
    • Ubuntu 18.04, 20.04
      • Linux* kernel 4.11 or higher deployments are expected
    • Red Hat Enterprise Linux* 8.1, 8.2
      • Linux* kernel 4.11 or higher deployments are expected
    • SLES 15 SP1
      • Linux* kernel 4.11 or higher deployments are expected
    • CentOS 8
      • Linux* kernel 4.11 or higher deployments are expected
    • gcc v5.1 or above
    • OpenCL drivers required to be installed
  • Linux Developer tools component installed, including gcc, g++ and related tools. (This is the list of component versions tested by Intel; other versions may or may not work and are not recommended
    • gcc 4.4 to gcc 7
    • binutils 2.20 to binutils 2.29
  • Library libunwind.so is required in order to use the -traceback option. Some Linux distributions may require that it be obtained and installed separately.

Windows*

  • Microsoft* Windows* 10
  • Microsoft* Windows* Server 2016
  • Microsoft* Windows* Server 2019

Note: only a limited subset of operating systems are supported for offload to supported accelerators

  • Microsoft* Windows* 10 x64

Developer Tools Requirements

  • To use the Microsoft Visual Studio* development environment or command-line tools to build IA-32 or Intel® 64 architecture applications:
    • Microsoft Visual Studio* 2017 Professional Edition (or higher edition) or Microsoft Visual Studio* Community 2017 with 'Desktop development with C++' component installed
    • Microsoft Visual Studio* 2019 Community, Enterprise and Professional Editions with 'Desktop development with C++' component installed
    • For addtional details see the article, Intel Compilers Compatibility with Microsoft Visual Studio and Xcode.
  • To use command-line tools only to build Intel® 64 architecture applications:
    • Microsoft Build Tools* 2017
    • Microsoft Build Tools* 2019
  • For OpenMP TARGET (ifx)

macOS*

macOS Versions Supported

  • macOS 10.15 Catalina
  • macOS 11.0, 11.2 Big Sur

Fortran Integration into Xcode Removed

Xcode integration capabilities within our Fortran Compiler bundle have been removed. Command line interface remains fully functional for macOS.

Keep in mind that installation of Xcode is still recommended, as command line tools from Xcode are required by the command line compiler. However, you can install just the Xcode Command Line Tools with this command from a terminal window:

xcode-select --install

Xcode for Command Line

  • Xcode 11 is available for command line tools use only. Fortran Integration into Xcode removed.
  • Xcode 12 is available for command line tools use only.
    • Fortran Integration into Xcode removed.
    • When linking with Xcode 12.0, Xcode 12.1 or Xcode 12.2 some libraries are not found.
      • Workaround

Install Xcode, then run:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

Then accept the license (only if you haven't yet) by:

sudo xcodebuild -license

Other macOS Information

  • In order to gain all functionality and optimal performance with Intel® oneAPI for macOS* we recommend installing both the Intel® oneAPI Base Toolkit AND the Intel® oneAPI HPC Toolkit. Both toolkits should be downloaded and installed for optimal performance and to obtain all available Intel Performance Libraries. Please refer to the Installation Guide for Intel® oneAPI Toolkits for obtaining and installing both toolkits.
  • There is no OpenMP TARGET support with macOS.

Notes

  • The Intel® compilers are tested with a number of different Linux distributions, with different versions of gcc. The version of glibc you use must be consistent with the version of gcc in use. For best results, use only the gcc versions as supplied with distributions listed above.
  • Compiling very large source files (several thousands of lines) using advanced optimizations such as -O3, -ipo and -qopenmp, may require substantially larger amounts of RAM.
  • Some optimization options have restrictions regarding the processor type on which the application is run. Please see the documentation of these options for more information.
