onetbb: onetbb (oneAPI Threading Building Blocks) onetbb: onetbb: oneTBB is a flexible C++ library that simplifies the work of adding onetbb: parallelism to complex applications, even if you are not a threading onetbb: expert. onetbb: The library lets you easily write parallel programs that take full onetbb: advantage of the multi-core performance. Such programs are portable, onetbb: composable and have a future-proof scalability. oneTBB provides you onetbb: with functions, interfaces, and classes to parallelize and scale the onetbb: code. All you have to do is to use the templates. onetbb:
