Organization of the Intel C/C++ Compilers

The Intel Compilers must be setup using a script to install important libraries paths and executable paths. The Intel C/C++ compiler version which is installed is 10.0.026. Both the 64-bit and the 32-bit version are available.

Intel Compiler Architecture/User Shell To Setup this version
64-bit/bourne shell source /usr/local/profile.d/iccvars.sh
64-bit/tcsh source /usr/local/profile.d/iccvars.csh
32-bit/bourne shell source /usr/local/profile.d/iccvars_x86.sh
32-bit/tcsh source /usr/local/profile.d/iccvars_x86.csh

For most users, the 64-bit version will be used. The 32-bit versions are provided as a resource in the event a 32-bit library must be linked against. After setup, icc is the intel c-compiler and icpc is the intel c++ compiler.

Some Useful Compiler Options

  • To generate highly optimized code, try compiling with "-03" or  "-fast" flags.
  • Use  "-w" to disable all warnings, "-Wall" to enable all warnings.
  • "-openmp" to generate code based on OpenMP directives
  • "-static" prevents linking with shared libraries (everything is statically linked)
  • setup the intel compilers and issue icc --help to see the full list of options.
