 Threading Building Blocks (TBB) is a C++ runtime library that abstracts the low-level threading details necessary for optimal multi-core performance.  It uses common C++ templates and coding style to eliminate tedious threading implementation work.
 TBB requires fewer lines of code to achieve parallelism than other threading models.  The applications you write are portable across platforms.  Since the library is also inherently scalable, no code maintenance is required as more processor cores become available.
