包括本次申请 是否超出系统所掌握的 剩余资源量 若不超出 则分配 否则等待 4 银行家算法的数据结构 1 系统剩余资源量 V n 其中 V n 表示第 I 类资源剩余量 2 已分配资源量 A m n 其中 A j i 表示系统 j 程已得到的第 i 资源的数量 3 剩余需求量 C m n 其中 C j i 对第 i 资源尚需的数目 5 银行家算法流程 当某时刻 某进程时 提出新的资源申请 系统作以下操作 1 判定 E n 是否大于 C j n 若大于 表示出错 2 判定 E n 是否大于系统剩余量 V n 若大于 则该进程等待 3 若以上两步没有问题 尝试分配 即各变量作调整 4 按照安全性推测算法 判断 分配过后 系统是否安全 若安全 则实际分配 否则 撤消分 配 让进程等待 6 安全性检测 算法 对进程逐个扫描 先判断 flag 看进程是否完成 如果完成则继续扫描 如果没有再 判断当前系统是否满足进程所需要的分配额 如果满足则分配并当进程完成后回收资源 如果没有则扫描下一个进程 扫描所有进程 如果所有的进程都能完成就表明是安全分配 序列 如果没有 则分配不成功 不存在着安全序列 课题二 处理机调度算法的实现课题二 处理机调度算法的实现 设计目的设计目的 在多道程序和多任务系统中 系统内同时处于就绪状态的进程可能有若干 个 也就是说能运行的进程数大于处理机个数 为了使系统中的进程能有条不紊地工作 必须选用某种调度策略 选择一进程占用处理机 要求学生设计一个模拟处理机调度算法 以巩固和加深处理机调度的概念 设计要求设计要求 1 先由用户输入进程数量 至少 5 个进程 再由系统随机生成一个进程序列 包括 到达时间和服务时间 2 然后显示进程调度算法由用户选择 包括 时间片轮转法 短作业优先算法 动态 优先级算法 3 显示结果包括每个进程的开始时间 完成时间 周转时间以及带权周转时间 显示 界面可参考书本的例子以表格形式但可不要表格线 课题三 生产者课题三 生产者 消费者问题消费者问题 设计目的设计目的 通过研究 Linux 的进程机制和信号量实现生产者消费者问题的并发控制 is one of the practical form of values The so called values refers to the objective things
