Why Adaptive Programs?
¨Critical software that realizes near peak performance requires detail knowledge of a host of interlocking and competing factors.
¨Performance can differ by factors of 10,even 100.
¨Tuning even the simplest operation generally requires an intense and sustained effort by highly technically advanced programmers.
¨Present day architectures are complicated, making predictability difficult, experimentation is a reliable way to achieve near peak performance.
