<p>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.</p>
