英特爾? C++ 編譯器 Windows 版本為所有基於英特爾? 處理器的平台供給疾速的開發和遜色的

遵從。它能夠對軟體執行自動優化和並行處理，從而充沛利用英特爾? 多核處理器（包羅雙核

移動平台、桌面平台以及企業平台）。

特性概覽：利用 Windows 版本的英特爾 C++ 編譯器編譯的軟體具備高級優化的功能，在此將對

一些功能進行簡單的講解，更為詳盡的介紹見如下鏈接：

1.多線程應用程式聲援，包羅用於簡單無效的軟體線程技術的 OpenMP 和自動並行處理。

2.過程間優化 (IPO) 對於搜羅許多罕用中、小函數的程式，特別是循環內搜羅調用的程式，IPO

或者極大地行進應用程式遵從。

3.檔案導引優化 (PGO) 通過高漲指令快取置換 (cache-thrashing)、重組代碼佈局、縮減代碼

長度並減少分支預測失誤來行進應用程式遵從。

4.自動向量器對代碼進行並行化處理，並調整數據，個中搜羅或者天生均衡負載的循環剝離技術，

以及或者匹配整個緩存線預取情況的循環展開技術。

5.高級優化 (HLO) 利用循環轉換和預取實現更進一步的優化。

6.利用英特爾? 調試器針對已優化代碼進行調試對於已針對英特爾? 體系結構進行優化的代碼，

能夠降職其調試過程的遵從。

英文說明:



Software compiled using the Intel C++ Compiler for Linux

benefits from advanced optimization features, a few of

which are explained briefly here, with links to more

complete descriptions:



* Multi-Threaded Application Support, including

OpenMP and auto-parallelization for simple and efficient

software threading.

* Auto-vectorization parallelizes code to utilize

the 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 best

utilizes the processor?s capabilities for cache and

memory accesses, SIMD instruction sets, and for multiple

cores. This revolutionary capability, new in version 10,

combines vectorization, parallelization and loop

transformations into a single pass which is faster, more

effective and more reliable than prior discrete phases.

* Interprocedural Optimization (IPO) dramatically

improves performance of small- or medium-sized functions

that are used frequently, especially programs that

contain calls within loops. The analysis capabilities of

this optimizer can also give feedback on vulnerabilities

and coding errors, such as uninitialized variables or

OpenMP API issues, which cannot be detected as well by

compilers which rely strictly on analysis by a compiler

front-end.

* Profile-guided Optimization (PGO) improves

application performance by reducing instruction-cache

thrashing, reorganizing code layout, shrinking code

size, and reducing branch mispredictions.

* Optimized Code Debugging with the Intel?Debugger

improves the efficiency of the debugging process on code

that has been optimized for Intel?architecture.
