Intel® Threading Building Blocks (Intel® TBB) 2.1 is an award-winning runtime library that simplifies the writing of multithreaded applications. Just as the C++ Standard Template Library (STL) extends the core language, Intel TBB offers C++ users a higher-level abstraction for parallelism. To implement Intel TBB, developers use familiar C++ templates and coding style, leaving low-level threading details to the library. It is also portable between architectures and operating systems. With Intel TBB, developers get the benefits of faster programming, scalable performance, and easier-to-maintain code. pdf
