<H2>Python* API for Intel® Threading Building Blocks (Intel® TBB).
|
|
</H2>
|
|
|
|
<H2>Overview</H2>
|
|
It is a preview Python* module which unlocks opportunities for additional performance in multi-threaded Python programs by enabling threading composability
|
|
between two or more thread-enabled libraries like Numpy, Scipy, Sklearn, Dask, Joblib, and etc.
|
|
<p></p>
|
|
The biggest improvement can be achieved when a task pool like the ThreadPool from the Python standard library or libraries like Dask or Joblib (used in multi-threading mode)
|
|
execute tasks calling compute-intensive functions of Numpy/Scipy/Sklearn/PyDAAL which in turn are parallelized using Intel® Math Kernel Library or/and Intel® TBB.
|
|
<p></p>
|
|
The module implements Pool class with the standard interface using Intel® TBB which can be used to replace Python's ThreadPool.
|
|
Thanks to the monkey-patching technique implemented in class Monkey, no source code change is needed in order to enable threading composability in Python programs.
|

Prior to building it, please set up the environment using corresponding tbbvars script, e.g. `source tbbvars.sh intel64`

<DT><TT>make</TT>
|
|
<DD>Default build and run. Equivalent to 'make release test'.
|

<DT><TT>make release</TT>
|
|
<DD>Compile and link against the release version of Intel TBB runtime library. The resulting executable is left in the directory for the example.
|

<DT><TT>make test</TT>
|
|
<DD>Run local build of the module previously produced by one of the above commands.

<DT><TT>make install</TT>
|
|
<DD>Install module into Python.
|
|
<DT><TT>make <B>[</B>(above options or targets)<B>]</B> CXX=<B>{</B>icl, icc<B>}</B></TT>
|
|
<DD>Build and run as above, but use Intel® C++ compiler instead of default, native compilers
|
|
(e.g., icl instead of cl.exe on Windows* systems, or icc instead of g++ on Linux* or OS X* systems).
|
|
Please note, CXX=icl works on Windows only with Intel® Distribution for Python*.

<H2>System Requirements</H2>
|
|
The Python module was not tested on older versions of Python thus we require at least Python versions 2.7 and 3.5 or higher.<BR>
|
|
SWIG must be of version 3.0.6 or higher<BR>
|
|
OS versions:
|
|
Microsoft* Windows* Server 2012,
|
|
Microsoft* Windows* 10,
|
|
Ubuntu* 14.04 LTS,
|
|
Red Hat* Enterprise Linux* 7.
