Eager Execution
Eager execution is a form of speculative execution where both sides of the conditional branch are executed, however the results are committed only if the predicate is true. With unlimited resources, eager execution (also known as oracle execution) would in theory provide the same performance as perfect branch prediction. With limited resources eager execution should be employed carefully since the number of resources needed grows exponentially with each level of branches executed eagerly.

Famous quotes containing the words eager and/or execution:
“I am grown by sympathy a little eager and sentimental, but leave me alone, and I should relish every hour and what it brought me, the pot-luck of the day, as heartily as the oldest gossip in the bar-room.”
—Ralph Waldo Emerson (1803–1882)
“My weakness has always been to prefer the large intention of an unskilful artist to the trivial intention of an accomplished one: in other words, I am more interested in the high ideas of a feeble executant than in the high execution of a feeble thinker.”
—Thomas Hardy (1840–1928)
