Add to ORKGRecent studies of dynamic branch prediction schemes rely almost exclusively on user-only simulations to evaluate performance. We find that an evaluation of these schemes with user and kernel references often leads to different conclusions. By analyzing our own Atom-generated system traces and the system traces from the Instruction Benchmark Suite, we quantify the effects of kernel and user interactions on branch prediction accuracy. We find that useronly traces yield accurate prediction results only when the kernel accounts for less than 5% of the total executed instructions. Schemes that appear to predict well under user-only traces are not always the most effective on full-system traces: the recently-proposed two-level adaptive schemes ca...
