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
AI and automation
Energy resource exploration
†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.

Get what you need to build, test, and optimize your oneAPI projects for free. With an Intel® DevCloud account, you get 120 days of access to the latest Intel® hardware—CPUs, GPUs, FPGAs—and Intel oneAPI tools and frameworks. No software downloads. No configuration steps. No installations.
Intel oneAPI Threading Building Blocks 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.
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.
This benchmark illustrates the performance scalability of Intel oneAPI Threading Building Blocks.
