On any Red Hat Enterprise Linux (RHEL) host we have support for using the new Intel® C/C++ Composer XE for Linux and Intel® Fortran Composer XE for Linux and some of the older version of the C/C++ and Fortan compilers that were shipped by Intel.
To setup your environment you will need to either load a GNU Module file or source some config files depending on your shell and architecture.
Module File
Rather than sourcing the scripts as mentioned below, you can load a pre-configured GNU Module file to the same end. You can run the following on RHEL8+/Ubuntu hosts to prepare your environment for either C/C++ or Fortran compilation:
module load intel/2020.1
C/C++
| Version | RHEL8+/Ubuntu Path |
|---|---|
| 10.0.026 | /opt/common/intel/cc/10.0.026 |
| 11.1 | /opt/common/intel/Compiler/11.1/current |
| 2011.1 | /opt/common/intel/composerxe-2011 |
| 13.1.1 | /opt/common/intel/composer_xe_2013_sp1.1.106 |
To use a version you need to source the bin/iccvars.csh for tcsh/csh users or bin/iccvars.sh for bash users. Additionally you need to specify the architecture on the command line when sourcing. For 32bit users that is ia32 and for 64bit that is intel64.
Example for a tcsh/csh user using the 64bit 13.1.1 version of the compiler on a RHEL8+ host:
source /opt/common/intel/composer_xe_2013_sp1.1.106/bin/iccvars.csh intel64
You can then use the icpc to compile with the Intel C++ Compiler or icc to compile with the Intel C Compiler.
Fortran
| Version | RHEL8+/Ubuntu Path |
|---|---|
| 10.0.026 | /opt/common/intel/fc/10.0.026 |
| 11.1 | /opt/common/intel/Compiler/11.1/current |
| 2011.1 | /opt/common/intel/composerxe-2011 |
| 13.1.1 | /opt/common/intel/composer_xe_2013_sp1.1.106 |
To use a version you need to source the bin/ifortvars.csh for tcsh/csh users or bin/ifortvars.sh for bash users. Additionally you need to specify the architecture on the command line when sourcing. For 32bit users that is ia32 and for 64bit that is intel64.
Example for a tcsh/csh user using the 64bit 13.1.1 version of the compiler on a RHEL8+ host:
source /opt/common/intel/composer_xe_2013_sp1.1.106/bin/ifortvars.csh intel64
You can then use the ifort command to compile with the Intel Fortran Compiler.
