Intel® oneAPI Threading Building Blocks(Beta)
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, 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

Download the Toolkit
Intel oneAPI Threading Building Blocks is included as part of the Intel® oneAPI Base Toolkit.
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.
Compatible with Other Threading Packages
Can coexist seamlessly with other threading packages. This gives you the flexibility to keep your legacy code as-is and use oneTBB for new implementations.
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.

Product and Performance Information
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
