  • 與 Eclipse* 3.0 開放源碼集成開發環境 (IDE) 集成，促進這套日益流行的替代性開發工具的廣泛采用。“英特爾 C++ 編譯器 Linux 版”隨帶一份 Eclipse，便于加速您的集成工作。
  • 備注：英特爾不提供有關 Eclipse IDE 的技術支持。
  • 可以同以前版本的英特爾編譯器安裝在一起。
  • 在英特爾安騰 2 處理器上支持“Mosberger 展開庫”。它與 GCC 運行時庫保持兼容。
  • “英特爾® 調試器”改善了對優化代碼的支持。
  • 改善了穩定性，縮短了編譯時間。
  • 提供經過改善和簡化的安裝過程，包括注冊過程。

• “英特爾 C++ 編譯器 Linux 版”可加速軟件開發、縮短配置時間、提高軟件性能并保護您在開發上所作的投資。此編譯器還具有以下這些優點：
  
  • 同 GCC 3.2、3.3 及 3.4 保持源代碼與二進制代碼方面的兼容性，并與廣泛使用的 Linux 開發實用程序（如 make、Emacs 及 gdb）兼容 - 可節省您的時間與精力。
  • 過程間優化 (IPO) 通過采用內嵌技術，用實際的函數代碼取代函數調用，并盡可能執行而非相對尋址，可以創建執行速度更快的代碼。
  • 高度優化的浮點模擬庫可用于開發性能要求高、使用浮點運算的應用程序。
  • 內部函數可從 C++ 級訪問，使得從 C++ 應用級使用“單指令多數據指令集”(SIMD) 技術非常方便。
  • 多線程應用程序支持，符合 OpenMP* 標準，具備自動并行功能。
  • 現在可以同以前的版本（如 8.1）安裝在一起。

Features

• Compatibility with the GNU tool chain protects your investment in the way you develop software on and for Linux* based systems.  Use Intel C++, gcc or both!
• Multi-Threaded Application Support including new in 11.0, OpenMP 3.0 (data- and now task-parallelism), and auto-parallelization for simple and efficient software threading.
• Auto-vectorization parallelizes code to utilize the Intel® Streaming SIMD Extensions (SSE) instruction set architectures (SSE, SSE2, SSE3, SSSE3, and SSE4) of our latest processors.
• High-Performance Parallel Optimizer (HPO) restructures and optimizes loops to ensure that auto-vectorization, OpenMP, or auto-parallelization make best use of cache and memory accesses, SIMD instruction sets, and multiple cores.  Compiles in a single pass, improving compile-time and producing more reliable code. 
• Interprocedural Optimization (IPO) dramatically improves performance of small- to mid-sized functions, especially in programs containing calls within loops. IPO analysis gives feedback on vulnerabilities and coding errors, such as uninitialized variables or OpenMP API issues, which cannot be detected as well by other compilers.
• Profile-guided Optimization (PGO) improves application performance by reducing instruction-cache thrashing, reorganizing code layout, shrinking code size, and reducing branch mispredictions.
• Intel® Threading Building Blocks is an award winning C++ template library that abstracts threads to tasks to create reliable, portable and scalable parallel applications. Intel® TBB is the most efficient way to implement parallel applications and unleash multi-core platform performance.
• Intel® Math Kernel Library includes optimized and scalable math routines for maximizing performance and seamlessly provides forward scaling from current to future many-core platforms.
• Intel® Integrated Performance Primitives is an extensive library of multi-core-ready, highly optimized software functions for multimedia data processing, and communications applications.
• Optimized-Code Debugging with the Intel® Debugger improves the efficiency of the debugging process on code that has been optimized for Intel® architecture.  Includes new threaded code debugging features and a new GUI.
• New integrated, simplified installation gets you going with all capabilities quickly and easily.  Simplified custom install makes it easy to identify just the components you want. 
• Ongoing Premier Support now includes online community support forums to speed information flow, in addition to private, password-protected accounts.  Technical support, interactive issues management, access to technical and application notes, product updates and more with every commercial and academic license. 

Technical Support

With the purchase of the product, you will receive one year of technical support and product updates from Intel® Premier Support, our interactive and password-protected issue management and communication web site. This premium support service allows you to submit questions, download product updates, and access technical notes, application notes, and other documentation.

Compatibility

The Intel C++ Compiler 11.0 for Linux is substantially standards compliant and compatible with the Linux distributions and gcc, and related tools chain.  It also supports Itanium® 2 processors, including Dual-Core Intel Itanium 2 processors.  Binaries are also substantially compatible with gcc binaries to support a mix and match interoperability capability.

The Intel C++ Compiler provides the following language conformances:

• ANSI/ISO standard for C language compilation (ISO/IEC 9899:1990)
• ANSI/ISO standard (ISO/IEC 14882:1998) for the C++ language
• OpenMP specification version 3.0
