Such programs are portable, +composable and have a future-proof scalability. oneTBB provides you with functions, interfaces, and classes to parallelize and scale the code. +All you have to do is to use the templates. + +The library differs from typical threading packages in the following ways: +* oneTBB enables you to specify logical parallelism instead of threads. +* oneTBB targets threading for performance. +* oneTBB is compatible with other threading packages. +* oneTBB emphasizes scalable, data parallel programming. +* oneTBB relies on generic programming. + + +Refer to oneTBB [examples](examples) and [samples](https://github.com/oneapi-src/oneAPI-samples/tree/master/Libraries/oneTBB) to see how you can use the library. + +oneTBB is a part of [oneAPI](https://oneapi.io).
