Intel C/C++ Compiler Plug-in

The column at the left has information to answer your questions. Select an information category and you'll see indexes of what is available.

What features are available in the latest updates to the Intel C/C++ Compiler plug-in?

The most recent updates allow current users of the compiler to install new features and improvements provided by the Intel C/C++ Compiler plug-in. The new features and improvements can be accessed from http://developer.intel.com/design/perftool/icl24/updates.htm

I installed the Intel C/C++ Compiler plug-in. How do I invoke it from within the Microsoft Visual C++ Integrated Development Environment?

Follow these steps:

Open a Microsoft project (.mdp or .mak) file in Visual C++.
Click on the "Tools" menu in the Developer Studio.
Click "Select Compiler". The Select Compiler window opens.
Click on the Intel C/C++ Compiler option.
Click "OK".

Is it possible to have the Intel Compiler active in both Microsoft Visual C++ Compiler 4.x* and Microsoft Visual C++ Compiler 5.0 in the same system?

No. Only one of the Intel C/C++ Complier plug-in or Intel FORTRAN Compiler plug-in can be active in a single version of Microsoft Visual C++ Compiler* at any time. To switch between versions of Microsoft Visual C++ Compiler, it is necessary to uninstall the Intel C/C++ Compiler plug-in(not simply deleting it) then re-install it selecting the different version of Microsoft Visual C++ Compiler on the "Select Microsoft Compiler" screen during Intel C/C++ Compiler plug-in installation.

How do I produce code that targets a particular processor?

To target a binary application to run on a specific processor, use the -Gn option to optimize for that processor:

-GB Choose GB when the binary application must run on a variety of Intel processors. This type blends optimization for performance across the entire Intel family of processors. The GB option is ON by default.

-G5 Choose G5 when the binary application runs on the Pentium® processor.

-G6 Choose G6 when the binary application runs on the Pentium Pro or Pentium II processors

Note: The -G target processor options and other optimization options are described in detail in the "Optimizations" chapter of the Intel C/C++ Compiler User's Guide for Win32 Systems.

Can I compile my application with a mix of the Intel C/C++ Compiler plug-in and the Microsoft Visual C++ Compiler?

Yes, the Intel C/C++ Compiler plug-in allows this through use of the _USE_INTEL_COMPILER and _USE_NON_INTEL_COMPILER macros. These macros are documented in the release notes.
