Intel Compiler Suite for Itanium 2 Processors is a package of compilers is for systems based on Intel Itanium 2 processors running Linux. The package includes both Intel C++ and Intel Fortran compilers for Linux.


Both compilers include the following features

  • Outstanding application performance
  • Compatibility with the gnu tool chain
  • High Performance Parallel Optimizer (HPO), which delivers parallelization and loop transformations
  • Interprocedural Optimization (IPO), which dramatically improves performance of frequently-used functions
  • Profile-Guided Optimization (PGO), which improves application performance by reducing instruction-cache thrashing, reorganizing code layout, shrinking code size, and reducing branch mispredictions
  • OpenMP 3.0 support, which raises the abstraction away from the API, simplifying threading and making code more portable

Unique to Intel C++
Exception handling uses existing build-options to product better-optimized code leading to improved application performance. IEEE 754R Standard implementation overcomes otherwise unavoidable precision issues implied by binary FP formats. Great for banking, accounting, billing, and e-commerce.

Unique to Intel Fortran
More Fortran 2003 support including object-oriented features such as CLASS declaration, SELECT TYPE constant, inheritance association and more. Other additions support deferred-length character entities, PUBLIC types with PRIVATE components (and vice versa), ENUMERATOR, IEEE Floating Point Exception Handling, ALLOCATE extensions, array constructor changes and more to bring your Fortran apps closer to the standard. These join C interoperability features introduced in the last release to make it easier to develop mixed-language applications.
