[Software Engineering] suanffenxi DL : 0: 设有n项独立的作业{1,2,…, n},由m台相同的机器加工处理。作业i所需要的处理时间为ti。约定：任何一项作业可在任何一台机器上处理，但未完工前不准中断处理；任何作业不能拆分更小的子作业。多机调度问题要求给出一种调度方案，使所给的n个作业在尽可能短的时间内由m台机器处理完。设计算法。 -Stand-alone operation with n items (1,2, ..., n), by m units the same machine processing. Job i the processing time required to ti. Convention: any one job can be processed on any machine, but does not pre-completion are not allowed to interrupt processing any operation can not be split smaller sub-operations. Multi-machine scheduling problem requires paper, a scheduling program, so that given the n-operation in the shortest possible time processed by m machines. Design algorithms.

[Software Engineering] cipandiaodu DL : 0: 设计程序模拟先来先服务FCFS，最短寻道时间优先SSTF，SCAN和循环SCAN算法的工作过程。假设有n个磁道号所组成的磁道访问序列，给定开始磁道号m和磁头移动的方向（正向或者反向），分别利用不同的磁盘调度算法访问磁道序列，给出每一次访问的磁头移动距离，计算每种算法的平均寻道长度。-Design program to simulate a first-come first-serve FCFS, shortest seek time first SSTF, SCAN and SCAN algorithms work cycle process. Suppose there are n number of tracks consisting of tracks access sequence for a given number m, and began to track the direction of head movement (forward or reverse), respectively, using a different track sequence to access the disk scheduling algorithm, given the head of each visit distance, calculate the average seek length for each algorithm.
