Abstract :
Careful memory scheduling can increase memory bandwidth and overall system performance. We present a new memory scheduler that makes decisions based on the history of recently scheduled operations, providing two advantages: it can better reason about the delays associated with complex DRAM structure, and it can adapt to different observed workload
