CPU-bound

In computer science, a task, job or process is said to be CPU-bound (or compute-bound) when the time it takes for it to complete is determined principally by the speed of the central processor. The term can also refer to the condition a computer running such a workload is in, in which its processor utilization is high, perhaps at 100% usage for many seconds or minutes, and interrupts generated by peripherals may be processed slowly or be indefinitely delayed.
