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 a standalone product as well as part of the following products:


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 PATH, LIB and INCLUDE environment variables, by running, or tbbvars.csh in <install_dir>/linux/tbb/bin.

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