Intel® C++ Compiler for Linux accelerates your software development, shortens your configuration time and improves your software performance while preserving your development investment. The compiler also provides these benefits:

• Compatibility with Linux utilities—including widely-used utilities such as make, Emacs, and gdb—saves you time and effort
• Interprocedure optimization (IPO) creates faster code through inlining, replacing multiple function calls with actual function codes, and performing absolute rather than relative addressing wherever possible
• Highly-optimized, floating-point emulation allows development of performance-sensitive applications that use floating-point operations.
• Intrinsic functions accessed from the C++ level make it easy to use Single Instruction Multiple Data (SIMD) technology from the C++ application level.
• Multithreaded application support for OpenMP* and auto-parallelization is available.
• Intel Debugger saves you effort.
Supports the new Intel Extended Memory 64 Technology (Intel EM64T).

What's new
Intel C++ Compiler 8.1 for Linux improves on existing functionality and continues to provide outstanding application performance for software running on Intel processors.

Here are some of the new features:

• Includes tools for Linux* software developers to create applications that run at top speeds on Intel processors using Intel Extended Memory 64 Technology (Intel EM64T). An add-on package includes all the features required to develop high performance applications with Intel EM64T.


• Note: The Intel C++ Compiler 8.1, Extended Memory 64 Technology Edition for Linux is a separate executable that is included with Intel C++ Compiler 8.1 for Linux. Please check your Intel Premier Support account for specific download information>
• Integrates with the Eclipse open source integrated development environment (IDE) to facilitate use of this increasingly popular development alternative.
• Intel C++ Compiler 8.1 for Linux ships with a copy Eclipse to expedite your integration efforts. For more information on Intel software products that are compatible with Eclipse, click here. Please Note: Intel does not provide technical support for the Eclipse IDE.
• Further helps you to develop high performance applications by:
  • Adding compiler options, such as /QipoN.
  • Simplifying compiler options, for example the -fast option combines the four existing compiler options /03, /Qipo, /static and /QxP into a single compiler option.
• Continues to provide compilers for the latest Intel Xeon™ processors.
• Allows developers to profile applications given specific workloads using the Compiler Code-Coverage Tool.
• Saves developers testing and debug time with the Compiler Test-Prioritization Tool.
• Supports both automatic and manual precompiled header processing, dramatically improving compilation time.
