Intel version 9 compiler

Overview

This compiler is Intel's latest release of the compiler with Fortran, C and C++ compilers.

Restrictions on Use

This compiler is only available on the Altix. You must recompile all Fortran sources that were compiled with compilers earlier than version 8.0, including those that create .mod files. Third-party libraries built with versions earlier than 8.0 will also need to be rebuilt. Fortran sources built with Intel Fortran 8.0 or later do not need to be recompiled for use with version 9.0.

Set Up Procedure

You will need to load a version 9 module to access the compiler.

Running the Code

The fortran compiler is called ifort and can be used to compile Fortran 77 and Fortran 90/95 code. The c/c++ compiler is called icc.

You are now able to use the environment variables FPATH and CPATH (for Fortran and c respectively) to control where the compiler looks for include files. There is also LIBRARY_PATH which controls where the linker looks for libraries and shared objects.

Further Information

Further information is available from:

• The Intel website for Fortran and C compilers.
• The man pages are also very useful (man ifort and man icc).
• The release notes can also be found in /opt/modules/cmplrs/intel/<version>/doc.
