![]() If one core completes its work while other cores still have a significant amount of work in their queue, oneTBB reassigns some of the work from one of the busy cores to the idle core. Initially, the workload is evenly divided among the available processor cores. OneTBB implements work stealing to balance a parallel workload across available processing cores in order to increase core utilization and therefore scaling. ![]() This approach groups TBB in a family of techniques for parallel programming aiming to decouple the programming from the particulars of the underlying machine. Tasks are then executed respecting graph dependencies. high-level parallel programming paradigms (a.k.a. ![]() The library manages and schedules threads to execute these tasks.Ī oneTBB program creates, synchronizes, and destroys graphs of dependent tasks according to algorithms, i.e. Using TBB, a computation is broken down into tasks that can run in parallel. OneAPI Threading Building Blocks (oneTBB formerly Threading Building Blocks or TBB), is a C++ template library developed by Intel for parallel programming on multi-core processors.
