VS2019配置MKL教程(Windows)

下載連接：https://software.intel.com/en-us/mkl

 

1.文件下載

官網註冊後，選擇MKL下載下來，安裝到指定目錄就行，不在多說。

 

2.配置文件

首先建立一個Windows桌面項目，再添加一個CPP源文件。

 

打開項目屬性頁--配置屬性，會多出Intel Performance...這一項，看下圖配置

 

在打開VC++目錄，進行配置。我安裝MKL的地方在D:\IntelSWTools

打開D:\IntelSWTools\compilers_and_libraries_2019.5.281\windows，因爲版本不一樣，可能後面的版本更新日期可能不一樣。按照下面根據你的狀況添加。

可執行文件目錄：D:\IntelSWTools\compilers_and_libraries_2019.5.281\windows\mkl\bin

包含目錄：D:\IntelSWTools\compilers_and_libraries_2019.5.281\windows\mkl\include

庫目錄：

D:\IntelSWTools\compilers_and_libraries_2019.5.281\windows\compiler\lib\ia32_win

D:\IntelSWTools\compilers_and_libraries_2019.5.281\windows\mkl\lib\ia32_win

 

打開連接器，在附加依賴項添加

mkl_intel_c.lib;mkl_intel_thread.lib;mkl_core.lib;libiomp5md.lib;

 

3.配置測試
