Intel Threading Building Blocks (also known as TBB) is an open-source portable C++ template library for writing software programs that take advantage of multi-core processors.
From Wikipedia:
Intel Threading Building Blocks (also known as TBB) is a C++ template library developed by Intel Corporation for writing software programs that take advantage of multi-core processors. The library consists of data structures and algorithms that allow a programmer to avoid some complications arising from the use of native threading packages such as POSIX threads, Windows threads, or the portable Boost Threads in which individual threads of execution are created, synchronized, and terminated manually.
Instead the library abstracts access to the multiple processors by allowing the operations to be treated as "tasks", which are allocated to individual cores dynamically.
