  • “英特尔® 调试器”改善了对优化代码的支持。
  • 改善了稳定性，缩短了编译时间。
  • 提供经过改善和简化的安装过程，包括注册过程。

• “英特尔 C++ 编译器 Linux 版”可加速软件开发、缩短配置时间、提高软件性能并保护您在开发上所作的投资。此编译器还具有以下这些优点：
  
  • 同 GCC 3.2、3.3 及 3.4 保持源代码与二进制代码方面的兼容性，并与广泛使用的 Linux 开发实用程序（如 make、Emacs 及 gdb）兼容 - 可节省您的时间与精力。
  • 过程间优化 (IPO) 通过采用内嵌技术，用实际的函数代码取代函数调用，并尽可能执行而非相对寻址，可以创建执行速度更快的代码。
  • 高度优化的浮点模拟库可用于开发性能要求高、使用浮点运算的应用程序。
  • 内部函数可从 C++ 级访问，使得从 C++ 应用级使用“单指令多数据指令集”(SIMD) 技术非常方便。
  • 多线程应用程序支持，符合 OpenMP* 标准，具备自动并行功能。
  • 现在可以同以前的版本（如 8.1）安装在一起。

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
