Threading Building Blocks (TBB) is a C++ template library developed by Intel for parallel programming on multi-core processors. Using TBB, a computation is broken down into tasks that can run in parallel. The library manages and schedules threads to execute these tasks.
A TBB program creates, synchronizes and destroys graphs of dependent tasks according to algorithms, i.e. high-level parallel programming paradigms (a.k.a. Algorithmic Skeletons). Tasks are then executed respecting graph dependencies. This approach groups TBB in a family of solutions for parallel programming aiming to decouple the programming from the particulars of the underlying machine.
TBB implements work stealing to balance a parallel workload across available processing cores in order to increase core utilization and therefore scaling. Initially, the workload is evenly divided among the available processor cores. If one core completes its work while other cores still have a significant amount of work in their queue, TBB reassigns some of the work from one of the busy cores to the idle core. This dynamic capability decouples the programmer from the machine, allowing applications written using the library to scale to utilize the available processing cores with no changes to the source code or the executable program file. In a 2008 assessment of the work stealing implementation in TBB, researchers from Princeton University found that it was suboptimal for large numbers of processors cores, causing up to 47% of computing time spent in scheduling overhead when running certain benchmarks on a 32-core system.
TBB, like the STL (and the part of the C++ standard library based on it), uses templates extensively. This has the advantage of low-overhead polymorphism, since templates are a compile-time construct which modern C++ compilers can largely optimize away.
TBB is a collection of components for parallel programming:
- Basic algorithms:
- Advanced algorithms:
- Memory allocation:
- Mutual exclusion:
- Atomic operations:
- Timing: portable fine grained global time stamp
- Task scheduler: direct access to control the creation and activation of tasks
The TBB commercial release 3.0 supports Windows (XP or newer), OS X (version 10.5.8 or higher) and Linux using Visual C++ (version 8.0 or higher, on Windows only), Intel C++ Compiler (version 11.1 or higher) or the GNU Compiler Collection (gcc). Additionally, the TBB open source community has contributed patches for Solaris, PowerPC, Xbox 360, QNX Neutrino, and FreeBSD.
