 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|.
