Intel® Threading Building Blocks (Intel® TBB) is a runtime-based parallel programming model for C++ code that uses threads. It consists of a template-based runtime library to help you harness the latent performance of multicore processors. Use Intel TBB to write scalable applications that:

Intel TBB is available as:

Intel TBB is installed with Parallel STL, an implementation of the C++ standard library algorithms with support for execution policies. For more information, see Getting Started with Parallel STL.


After installing Intel TBB, you need to set the environment variables. This may be done as part of an edition-level command-line, or you can set just the Intel TBB environment variables, by running tbbvars.{sh|csh|bat} in <install_dir>/{linux|mac|windows}/tbb/bin.

<install_dir> is the installation directory, by default, it is:
