Intel® oneAPI Threading Building Blocks

Scalable Parallel Programming at Your Fingertips

Advanced Threading for Fast Applications

Intel® oneAPI Threading Building Blocks (oneTBB)† is a flexible performance library that simplifies the work of adding parallelism to complex applications across accelerated architectures, even if you’re not a threading expert.

oneTBB is ideal for a wide range of compute-intense domains, such as:

  • Numeric weather prediction
  • Oceanography
  • Astrophysics
  • Genetic engineering
  • Seismic exploration
  • AI and automation
  • Energy resource exploration
  • Socioeconomics

†Intel® Threading Building Blocks (Intel® TBB) is now called Intel oneAPI Threading Building Blocks (oneTBB) to highlight that the tool is part of the oneAPI ecosystem.

Download as Part of the Toolkit

oneTBB is included in the Intel® oneAPI Base Toolkit, which is a core set of tools and libraries for developing high-performance, data-centric applications across diverse architectures.

Download the Stand-Alone Version

A stand-alone download of oneTBB is available. You can download binaries from Intel or choose your preferred repository.

Features

oneTBB differs from typical threading packages in the following ways:

Specify Logical Performance, Not Threads
A runtime library automatically maps logical parallelism onto threads, making the most efficient use of processor resources.
 

Targets Threading for Performance
Focuses on the specific goal of parallelizing computationally intensive work, delivering higher-level, simpler solutions.


Coexists with Other Threading Packages
Seamlessly compatible with other threading packages, it gives you the flexibility to keep your legacy code as-is and use oneTBB for new implementations.

Emphasizes Scalable, Data-Parallel Programming
Rather than breaking up a program into functional blocks and assigning a separate thread to each, oneTBB emphasizes data-parallel programming, enabling multiple threads to work on different parts of a collection. This scales well to larger numbers of processors by dividing the collection into smaller pieces. Program performance increases as you add processors and accelerators.
