Anticiparallelism (Anticipatory Parallelism) is a term coined by
Bob Metcalfe in 1998. It is a technique of using
idle machine cycles to perform useful computing tasks in the background. Such tasks must be readily interrupted for intervals when the computer needs to return to its primary task. An example
of such a task is transmitting e-mail.
[ Anticiparalleism is also known as ]speculative execution
Speculative execution is an optimization (computer science), optimization technique where a computer system performs some task that may not be needed. Work is done before it is known whether it is actually needed, so as to prevent a delay that woul ...
