<h1 class="title">Intel® Threading Building Blocks.<br>fgbzip2 sample</h1>
</div>
<p>
fgbzip2 is a parallel implementation of bzip2 block-sorting file compressor that uses tbb::flow.
The output of this application is fully compatible with bzip2 v1.0.6 or newer.
<br><br>
<i>
This example includes software developed by Julian R Seward. See
<a href="#copyright">here</a> for copyright information.
</i>
<br>
It exemplifies support for asynchronous capabilities in the flow graph API, in particular async_node and async_msg.
<br><br>
This example uses C++11 lambda expressions. Specifying a compiler option such as -std=c++11 or similar might be necessary in order to build the example.
For more information please refer to the documentation for the compiler you use.
