WebAug 4, 2024 · Work stealing is a process that happens automatically in multicore CPUs. Each core has a queue of tasks to perform. When a processor completes its tasks, it then steals another task from the queue of another processing core. This helps to prevent the processor from having some cores sit idle while others still have a queue of tasks to … Webstealing is a restriction of Cilk-like work stealing in which a pro-cessor blocked on a task at depth d can only steal tasks from other processors at depth greater than d.
