On any RedHat 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 source some config files depending on your shell and architecture or load a module file.

C/C++

Intel C/C++ Versions
Version RHEL6/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 RHEL6 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

Intel Fortran Versions
Version RHEL6/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 RHEL6 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.

Module File

In addition to sourcing the scripts as mentioned above, you can load a pre-configured GNU Module file to the same end. You can run the following on RHEL6 hosts to prepare your environment for either C/C++ or Fortran compilation:

   module load intel/13.1.1
