As NDRR fails to provide latency bound when real-time queue is under bursty traffic,a new scheduling discipline named Auto-adaptive Weight Nested DRR(AWNDRR)is presented,which allocates more quanta to real-time queue as its length exceeds a fixed value.

Two new methods for partitioning and mapping nested loops with non-constant dependencies into distributed memory multiprocessors are presented.

In this paper, the realization of the exam system in human-computer interaction, automatic scoring and other functions, and discusses in detail the way the use of nested loops and random questions random questions with the order of the specific process of support.
