System Environment

Intel® DAAL version : 2016 Gold Initial Release (w_daal_2016.0.110.exe)

OS : Windows* 8.1

IDE : Visual Studio 2013

 

Overview

 Intel® DAAL is a part of Intel® Parallel Studio XE 2016, a developer toolkit for HPC and technical computing applications. Intel® DAAL is a powerful library for big data developers that turns large data clusters into meaningful information with advanced analytics algorithms.

 In this tutorial, we will see how to build and run Intel® DAAL C++ examples included in the package.
 

Finding the examples

 By default, the examples are located at

c:\Program Files (x86)\intelSWTools\compilers_and_libraries\windows\daal\examples

in examples directory, there are example projects in C++ and Java language respectively. The example data according to three different models, batch, distributed and online, for the projects is located in data directory.

 It is recommended to copy the examples to somewhere else where you don't need the administrator access in order to make it easy to modify, build and run.

 

Building the examples

  First, open the DAALExamples.sln solution file located in

 <DAAL Examples>\cpp

Select all projects and open up Properties -> Click Configuration Manager at the upper right corner -> Change active solution platrofm according to your platform. (e.g. Win32 -> x64 )

As the next step, we need to enable DAAL for the projects. Propertise -> Intel Performance Libraries -> Use Intel DAAL -> Choose Default Linking Method

Click Build Menu -> Build Solution (or Ctrl + Shitf + B)

 

Running the examples

 There is a couple more steps to take before running DAAL applications.

 First, to setup DAAL environment variables, run daalvars.bat <arch>

 Second, set redist runtime dlls ->

PATH=C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2016.0.110\windows\redist\intel64_win\daal;
C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2016.0.110\windows\redist\intel64_win\compiler;
C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2016.0.110\windows\redist\intel64_win\tbb\vc_mt;%PATH%

 

 Now go to <examples>\cpp and run one of the examples
