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:
“Always too eager for the future, we
Pick up bad habits of expectancy.
Something is always approaching; every day
Till then we say....”
—Philip Larkin (1922–1986)
“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)
