Parallelization Using Intel® Threading Building Blocks (Intel® TBB)

Compiler Methodology for Intel® MIC Architecture

Parallelization Using Intel® Threading Building Blocks (Intel® TBB)

Overview

The Intel® Composer XE 2013 for Linux suite includes the Intel® Threading Building Blocks (Intel® TBB) library which includes support for the Intel® Xeon Phi™ coprocessor . Intel® TBB is one of many options available for you to parallelize your application. TBB is a popular form of threading parallelism implemented by a C++ template library. We do not cover details on Intel TBB use on Intel® Xeon Phi™ coprocessors in this document. This information is covered in separate documentation included with the compiler and available online.

About Intel® Threading Building Blocks

Intel® Threading Building Blocks (Intel® TBB) is a widely used C++ template library for creating scalable parallel applications. Using Intel TBB, developers can easily develop robust task-based parallel applications that abstract platform details and threading mechanisms to provide performance improvement. Who should be interested in Intel TBB? If you are a C++ programmer and confident in the use of template libraries, this is an ideal choice for parallelization. Properties of Intel TBB:

  • Enhanced Productivity and Reliability - Intel TBB provides abstractions that make it easier to get scalable and reliable parallel applications with fewer lines of code
  • Scalability with Future-proofing - Application performance automatically improves as processor core count increases by using abstract tasks
  • Comprehensive - Intel TBB provides a set of robust components needed to implement parallel code

Intel TBB Web Portal: Videos, samples, case studies, technical articles, blogs, and user forums are all accessible online. Visit http://software.intel.com/en-us/intel-tbb/

The Intel® C++ Composer XE 2013 contains an entire documentation library on Intel TBB. Open your "Getting Started with the Intel® C++ Composer XE 2013 for Linux*" document and scroll down to find a link to "Intel® Threading Building Blocks Documentation". You can also directly access this information with your installed product. Assuming you used the default installation path, the Intel TBB documentation is available at http://software.intel.com/en-us/articles/intel-threading-building-blocks-documentation. This includes a Getting Started guide, Documentation, a Class Hierarchy Documentation, Examples, and Release Notes.
