Query: Reducing Load Latency with Cache Level Prediction   High load latency that results from deep cache hierarchies and relatively
slow main memory is an important limiter of single-thread performance. Data
prefetch helps reduce this latency by fetching data up the hierarchy before it
is requested by load instructions. However, data prefetching has shown to be
imperfect in many situations. We propose cache-level prediction to complement
prefetchers. Our method predicts which memory hierarchy level a load will
access allowing the memory loads to start earlier, and thereby saves many
cycles. The predictor provides high prediction accuracy at the cost of just one
cycle added latency to L1 misses. Experimental results show speedup of 7.8\% on
generic, graph, and HPC applications over a baseline with aggressive
prefetchers.
