|short_name| Get Started Guide provides the information you need to begin working with oneTBB.
|
|
It is helpful for new users of parallel programming and experienced developers that want to improve code performance.
|
|
|
|
It is recommended for you to have a basic knowledge of C++ programming and some experience with parallel programming concepts.
|
|
|
|
|full_name| is a runtime-based parallel programming model for C++ code that uses tasks.
|
|
The template-based runtime library can help you harness the latent performance of multi-core processors.
|
|
|
|
oneTBB enables you to simplify parallel programming by breaking computation into parallel running tasks. Within a single process,
|
|
parallelism is carried out by mapping tasks to threads. Threads are an operating system mechanism that allows the same or different sets of instructions
|
|
to be executed simultaneously. Using threads can make your program work faster and more efficiently.
|
|
|
|
Here you can see one of the possible executions of tasks by threads.

|
|
Use oneTBB to write scalable applications that:
|
|
|
|
* Specify logical parallel structure instead of threads.
|
|
* Emphasize data-parallel programming.
|
|
* Take advantage of concurrent collections and parallel algorithms.
|
|
|
|
oneTBB supports nested parallelism and load balancing. It means that you can use the library without worrying about oversubscribing a system, which happens when more tasks are assigned to a system than it can handle efficiently.
|
|
|
|
oneTBB is used in different areas, such as scientific simulations, gaming, data analysis, etc.
|
|
|
|
It is available as a stand-alone product and as part of the |base_tk|.
