Intel Compilers for Linux

The Intel Composer XE 2013 sp1 C/C++ and Fortran compilers are available from all Linux machines. The Intel compilers include a C compiler (icc), C++ Compiler (icpc), a Fortran 77/Fortran 90 Compiler (ifort), and a debugger (idb).

Intel's Documentation/Support page for the Intel Composer XE 2013 for Linux:

The Intel compilers come with shell scripts that will set up your environment correctly for using the compilers.

If you use the bash shell, execute these commands:

INTEL=/usr/local/intel/composerxe
source ${INTEL}/bin/compilervars.sh intel64

If you use the tcsh shell,  execute these commands:

setenv INTEL "/usr/local/intel/composerxe"
source ${INTEL}/bin/compilervars.sh intel64

If you plan to use the Intel compilers regularly, it is recommended that you add the above lines to your .bashrc or .cshrc file, so the correct environment will be set everytime you log in.
