Intel Fortran Compiler Usage
Details of the Intel Fortran Installation

Organization of the Intel Fortran Compiler

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

Intel Compiler Architecture/User Shell   To Setup  this version
 64-bit/bourne shell  source /usr/local/profile.d/ifortvars.sh
 64-bit/tcsh  source /usr/local/profile.d/ifortvars.csh
 32-bit/bourne shell
  source /usr/local/profile.d/ifortvars_x86.sh
 32-bit/tcsh  source /usr/local/profile.d/ifortvars_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 the setup, ifort is the binary for the Intel Fortran Compiler.

Some Useful Compiler Options

  • To generate very optimized code, try  compilation 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 ifort --help to see the full list of options.
