Statistical Sampling



Cycle-accurate full-system multiprocessor simulation is impractical because it is often six or more orders of magnitude slower than real hardware. Statistical sampling of microarchitecture simulation reduces overall cycle-accurate simulation for complete program runs by four orders of magnitude and allows for embarrassingly parallel simulation of independent windows of cycle-accurate simulation. Unlike conventional schemes measuring a single or a few simulation windows, statistical sampling aggregates results over hundreds of short measurements to provide a rigorous confidence in estimates.
