== Introduction ==
* MKL focuses on computation. DAAL focuses on the entire data flow (aquisition, transformation, processing).
* Optimized for all kinds of Intel based devices (from data center to home computers)
* Vectorization method used for optimization
DAAL supports 3 processing modes

== How DAAL Works ==
[[Image:DAALDataflow.PNG|center|600px ]]
== Installing DAAL ==
DAAL is already bundle with Intel® Parallel Studio XE 2016 Composer, Professional, or Cluster Edition, but you can also purchase a stand-alone version. To install it, you will have to execute the batch file to setup the environment.
By default, the batch to setup the environment is located at the ''<install dir>'' at ''C:\Program files (x86)\IntelSWTools\compilers_and_libraries_2016.x.xxx\windows''.
<u>'''Set Environment Variables'''</u>
Run the ''<install dir>\daal\bin\daalvars.bat'' script as appropriate to your target architecture.
''IA-32 architecture:''
daalvars.bat ia32
''Intel® 64 architecture:''
daalvars.bat intel64

<u>'''Compiling'''</u>
Tells the compiler to link with standard threaded Intel DAAL:
/Qdaal or
/Qdaal:parallel
Tells the compiler to link with sequential version of Intel DAAL:
/Qdaal:sequential
Visual Studio:
# In Solution Explorer, go to '''Project''' > '''Properties''' > '''Configuration Properties''' > '''Intel Performance Libraries'''.
# From the '''Use Intel DAAL''' drop-down menu, select the appropriate linking method. For example: ''Multi-threaded Static Library''.
'''''NOTE:''' DAAL may require you to also enable TBB. ''
