Parallelism-Aware Batch Scheduling: Enabling High-Performance and Fair Shared Memory Controllers

Uncontrolled interthread interference in main memory can destroy individual threads´ memory-level parallelism, effectively serializing the memory requests of a thread whose latencies would otherwise have largely overlapped, thereby reducing single-thread performance. The parallelism-aware batch scheduler preserves each thread´s memory-level parallelism, ensures fairness and starvation freedom, and supports system-level thread priorities.
