A Tutorial on the Java API of Intel® Data Analytics Acceleration Library

System Environment

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

OS : Windows 8.1

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 Java examples included in the package.

For C++ examples please refer -> Tutorial for Intel® DAAL : Using simple C++ examples

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

Second, we need to setup path for the location of javac.exe

set JAVA_HOME=<Your JDK location >
set PATH=%JAVA_HOME%\bin;%PATH%

Now go to <examples>\java

launcher.bat <arch> build

Then .class files will be generated at

<examples>\java\com\intel\daal\examples\association\rules

Running the examples

To run the examples, 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>\java and run one of the examples

launcher.bat <arch> run

The results from the examples will be saved at

<examples>\java\_results

Each example will generate a result file respectively, and you can see the result by opening .res file.
