[Process-Thread] gege DL : 0: 进程调度算法：采用最高优先数优先的调度算法（即把处理机分配给优先数最高的进程）和先来先服务算法。每个进程有一个进程控制块（ PCB）表示。进程控制块可以包含如下信息：进程名、优先数、到达时间、需要运行时间、已用CPU时间、进程状态等等。　　进程优先数及需要的运行时间可以事先人为地指定（也可以由随机数产生）。进程的到达时间为进程输入的时间。进程的运行时间以时间片为单位进行计算。　 -The process of scheduling algorithms: the use of the highest priority number of priority scheduling algorithm (ie the number of processors allocated to the highest priority process) and first-come first-serve algorithm. Each process has a process control block (PCB) said. Process control block can contain the following information: process name, priority number, arrival time, the need for run-time, has spent CPU time, the process of state and so on. Process priority number and needs of the running time can be artificially designated in advance (you can also by the random number generator). Process input arrival time for the process time. The process of running time to time slice is calculated as a unit.

[Process-Thread] jcgl DL : 0: （1）设计进程控制块PCB表结构，分别适用于优先权调度算法和时间片轮转调度算法。 PCB结构包括以下信息：进程名、进程优先数（或轮转时间片），进程所占用的CPU时间，进程的状态，当前队列指针等。根据调度算法的不同，PCB结构的内容可以作适当的增删。（2）建立进程就绪队列。对两种不同算法编制入链子程序。（3）编制两种进程调度算法：a）优先数调度；b）时间片轮转调度。允许用户在程序运行时选择使用某一种调度算法。-(1) design process control block PCB table structure, respectively, applicable to the priority scheduling algorithm and the time slice rotation scheduling algorithm. PCB structure includes the following information: process name, process priority number (or the rotation time slice), the process of occupying CPU time, the process of the state, such as the current queue pointer. According to the different scheduling algorithm, PCB content of the structure can be used for appropriate additions and deletions. (2) the establishment of the process ready queue. Algorithm on two different procedures for the preparation into the chain. (3) the process of the preparation of two scheduling algorithms: a) the number of scheduling priority b) time slice scheduling rotation. Allows the user to choose to use when running a particular scheduling algorithm.

[Process-Thread] Cycle-time-slice-rotary-algorithm DL : 0: 实验任务设计一个程序,根据不同的调度算法模拟操作系统对进程的调度。调度算法: 时间片循环法 1、设计进程控制块PBC表结构，适用循环时间片轮转算法。 2、 PBC结构通常包括以下信息：进程名、进程优先数、轮转时间片、进程的CPU时间，进程状态等。根据调度算法不同，PCB结构可作适当的调整。 3、建立进程队列。对不同的算法编制不同的入链程序。程序要求达到的运行效果：在设置好进程数量、调度算法后，系统能按设定的参数运行，并在屏幕上交替显示就绪队列和完成队列的进程名等信息-The task Design a program, according to the different scheduling algorithm simulation operating system to process scheduling. Scheduling algorithm: time slice cycle method 1, design process control block PBC table structure, it is suitable for cycle time slice rotary algorithm. 2, PBC structure usually include the following information: name of the process, process priority number, cycle time slice, process of CPU time, process status, etc. According to the different scheduling algorithm, PCB structure can make the appropriate adjustment. 3, establish process queue. To different algorithms to different into chain program. The process requirements to achieve the effect of operation: in the set up process quantity, scheduling algorithm, the system can be set according to the parameters of the operation, and on the screen alternate display ready queue and complete queue process information such as name
