We make three observations in modern processors: (1) LLC capacity is gettinglarger (up to 1GB); (2) core counts are increasing (up to 128 cores),accumulating a more significant amount of private L2 cache capacity on thechip; and (3) overall processor utilization in the cloud remains very lowdespite many efforts, leaving many large private caches unused. To enablebetter use of these beefy processors, we propose to open up a logical path forLLC evictions to unused private caches. In other words, instead of writing LLCevictions back to slow and busy main memory, we send some of them that arestill alive up to idle L2 caches to avoid unnecessary long and costly mainmemory. Our scheme takes the importance of applications (user-facing vs.background), and system load into account to provide each application with afair share of idle resources. Our results show that we can improve systemperformance by up to 2X (geomean of 10%) for single-application runs. Also, formixes of user-facing and background jobs, our scheme improves the P99 latencyof user-facing tasks by up to 32% (geomean of 15%), and the IPC of backgroundjobs by up to 50% (geomean of 10%).
