Lookahead prefetching with signature path

WebSignature path prefetching (SPP). This state-of-the-art delta prefetcher predicts irregular strides at the L2 cache [35]. SPP works by relying on the signatures (hashes of consecutive strides) observed within an OS page to index into a table that predicts future deltas. SPP uses a lookahead mechanism WebLookahead Optimizer. This repository contains implementations for Lookahead Optimizer: k steps forward, 1 step back in TensorFlow and PyTorch. Lookahead improves the learning stability and lowers the variance of its inner optimizer with negligible computation and memory cost. It is simple to incorporate into an existing machine …
