oneTBB (oneAPI Threading Building Blocks) is a C++ library for adding task-based parallelism to applications, letting developers express logical parallelism rather than manage threads directly. It provides parallel algorithms, flow graphs, concurrent containers, and a scalable memory allocator, and is an implementation of the oneAPI specification under the UXL Foundation.

Use cases

• parallelize CPU-bound C++ code across multiple cores
• build data-parallel pipelines and task flow graphs
• replace raw std::thread management with composable task-based parallelism
• get a scalable multithreaded memory allocator (tbbmalloc)
• write portable parallel code for Windows, Linux, and macOS
• scale performance-sensitive algorithms to many-core processors

When to choose

• you want high-level, composable parallelism in C++ without being a threading expert
• you need scalable data-parallel programming and work-stealing scheduling
• you want a mature, permissively licensed (Apache-2.0) library compatible with other threading packages
• you are targeting the oneAPI ecosystem

When to avoid

• you need GPU or heterogeneous offload rather than CPU threading
• your project is not C++ or cannot link native libraries
• you only need simple async concurrency already covered by std::async or coroutines
• you need distributed-memory (multi-node) parallelism like MPI
