Abstract
The paper proposes a predictor-guided last-level cache (LLC) writeback technique. This technique uses a rank idle predictor to predict when a rank will have significant idle time. "Rank idle" means that there will be no read request for this rank that will be delayed by scheduling writeback events. The scheduled dirty cache blocks can be written back during this idle rank period. Write-induced interference is significantly reduced by this technique.
