<h1 class="topictitle1">Introducing Intel® Threading Building Blocks</h1> <div> <div class="section"> <p>Intel® Threading Building Blocks (Intel® TBB) is a library that supports scalable parallel programming using standard ISO C++ code. It does not require special languages or compilers. It is designed to promote scalable data parallel programming. Additionally, it fully supports nested parallelism, so you can build larger parallel components from smaller parallel components. To use the library, you specify tasks, not threads, and let the library map tasks onto threads in an efficient manner. </p> <p>Many of the library interfaces employ generic programming, in which interfaces are defined by requirements on types and not specific types. The C++ Standard Template Library (STL) is an example of generic programming. Generic programming enables Intel® Threading Building Blocks to be flexible yet efficient. The generic interfaces enable you to customize components to your specific needs. </p> <p>The net result is that Intel® Threading Building Blocks enables you to specify parallelism far more conveniently than using raw threads, and at the same time can improve performance. </p> <p>This document is a reference manual. It is organized for looking up details about syntax and semantics. You should first read the <em>Intel® Threading Building Blocks Getting Started Guide</em> and the <em>Intel® Threading Building Blocks Tutorial</em> to learn how to use the library effectively. The <em>Intel® Threading Building Blocks Design Patterns</em> document is another useful resource. </p> <div class="Note"><h3 class="NoteTipHead"> Tip</h3> <p>Even experienced parallel programmers should read the <em>Intel® Threading Building Blocks Tutorial</em> before using this reference guide because Intel® Threading Building Blocks uses a surprising recursive model of parallelism and generic algorithms. </p> </div> </div> <p> <div class="tablenoborder"><table cellpadding="4" summary="" frame="border" border="1" cellspacing="0" rules="all"> <thead align="left"> <tr> <th class="cellrowborder" align="left" valign="top" width="100%" id="d90964e74"> <p>Optimization Notice </p>

These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
