​Intel® Threading Building Blocks

Intel® Threading Building Blocks (Intel® TBB) makes parallel performance and scalability accessible to software developers who are writing loop- and task-based applications. Build robust applications that abstract platform details and threading mechanisms while achieving performance that scales with increasing core count.

Customer Feedback

"DreamWorks* Fur Shader used Intel TBB, which produced an average of five times the speedup on a fur generation loop."

— DreamWorks

"Intel TBB was an invaluable help in multithreading our in-house renderer CGI Studio* and is now also used in animation and simulation software. Besides the ease of use, it takes care of the two most important aspects of running an application on multiple cores: load balancing and scalability."

— Maurice van Swaaij, Blue Sky Studios*

"Using Intel TBB’s [sic] new Flow Graph feature, we accomplished what was previously not possible, parallelizing a very sizable task graph with thousands of interrelationships all in about a week."

— Robert Link, Global Change Assessment Model (GCAM) project scientist, Pacific Northwest National Laboratory

"The Intel TBB Flow Graph [sic] interface lets us quickly add parallelism to GE* healthcare ultrasound products and get great performance. The features and flexibility of the flow graph interface lets us express the dependencies between our image calculations, exposing the parallelism in the computation, without the need to hand-roll a complex threading layer."

— Paul O’Dea, software architect, General Electric (GE) Healthcare*

"Intel TBB provided us with optimized code that we did not have to develop or maintain for critical system services. I could assign my developers to code what we bring to the software table."

— Michaël Rouillé, CTO, Golaem

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.
