Intel oneAPI Threading Building Blocks (oneTBB)

Intel oneAPI Threading Building Blocks (oneTBB) is an open source library to write parallel C++ programs that take full advantage of multicore performance, are portable and composable, and have future-proof scalability. Through community involvement, oneTBB is a feature-rich and popular solution for developing shared memory parallel applications. It has been used in production for data analytics, creative content creation, and many other applications.
oneTBB is compiler-independent and is available on a variety of processors and operating systems. It is used by other oneAPI libraries (Intel oneAPI Math Kernel Library, Intel oneAPI Deep Neural Network Library, etc.) to express multithreading parallelism for CPUs.

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.
