重新调度,是一种变更当前执行线程的操作。
如果这时发生了抢占,由于重新调度,FPU状态就会与抢占前完全不同。
If preemption happens here, then upon reschedule, the FPU state is completely different from what was there before preemption.
哪些被取消调度的步骤没有被重新调度或哪些步骤重写了其初始调度?
Which steps have been de-scheduled without being re-scheduled or had their original schedule overwritten?
只有在重新调度是在两个进程间进行的时候,进程上下文才被转换。
The process context only needs switching if a reschedule is between threads in different processes.
那样的话,那个任务将会跳过这段周期的执行,重新调度到下个周期。
In that case, the task will skip execution of this period and reschedule to the next period.
即使有少量失败的CAS操作,这种方法仍然会比由于锁争用造成的重新调度快得多。
Even with a few failed CAS operations, this approach is still likely to be faster than being rescheduled because of lock contention.
暂挂和重新调度线程的开支很显著,其中包括JVM、操作系统和硬件的工作。
There is significant overhead to suspending and rescheduling a thread, which involves work by the JVM, operating system, and hardware.
更细的粒度降低了争用的机会,不用重新调度就能重试的能力也降低了争用的成本。
The finer granularity reduces the chance that there will be contention, and the ability to retry without being descheduled reduces the cost of contention.
光是威胁再进行劳工运动就已经让英国航空公司承诺从其他航空公司租赁飞机,重新调度员工以便完成任务。
The mere threat of further industrial action has involved it in commitments to lease planes from other airlines and redeploy staff in order to fulfil its schedules.
jobtracker还检查请求的工作,如果一个datanode由于某种原因失败,jobtracker会重新调度以前的任务。
The jobtracker also validates requested work and, if a datanode fails for some reason, reschedules the previous task.
如前所述,此值用于阻止重新路由一些适用请求,这些请求已经被故意路由到一个特定调度程序,从而路由到已经在那里托管的一个服务实例。
As mentioned before this is used to prevent re-routing of applicable requests which deliberately have been routed to a specific dispatcher and thus a service instance hosted there already.
每200毫秒,调度程序就执行一次负载平衡调节,以便重新分配任务负载,维持处理器之间的平衡。
Every 200 milliseconds, the scheduler performs load balancing to redistribute the task loading to maintain a balance across the processor complex.
在2.4版本的调度器中,时间片重算算法要求在所有的进程都用尽它们的时间片以后,它们的新时间片才会被重新计算。
In the 2.4 scheduler, the timeslice recalculation algorithm requires that all processes exhaust their timeslice before their new timeslices can be recomputed.
当拥有锁的线程离开临界区的时候,挂起的线程需要被重新唤醒,然后重新被调用,并交换上下文,回到CPU调度中。
When the thread that has the lock leaves the critical section, the suspended thread needs to be woken up. The thread will need to be re-scheduling and context switched back into the CPU.
如果内存存在多于一个进程,那么其余进程就会要等待,当CPU空闲的时候,就重新开始调度。
If there are more processes, the rest will have to wait until the CPU is free and can be rescheduled.
理论上,内存管理器能足够快速的交换一些已在内存中的过程,当调度器要重新规划CPU时,准备执行。
Ideally , the memory manager can swap processes fast enough that some processes will be in memory , ready to execute , when the CPU scheduler wants to reschedule the CPU .
然后,从对象的等待集中删除线程t,并重新进行线程调度。
The thread t is then removed from the wait set for this object and re-enabled for thread scheduling.
每个CPU在自己的队列中进行调度,如果没有可运行的KSE,则从其他CPU那里取一些有软亲缘的KSE,并且重新排序。
Each CPU schedules from its own queues, and resorts to stealing runnable softly affined KSEs from other CPUs if there are no runnable KSEs.
船长:港口调度通知我们泊位已被取消,所以我们又等了10小时重新安排泊位。
Captain: the Port Control informed us that our berth arrange had been cancelled, so we waited for 10 hours for another berth arrangement.
随着进程的执行和阻塞,他们将被重新置于相同优先级任务列表的尾部,从而进行有效的循环调度。
As processes run and block they will be re-queued at the end of the like priority task list and effectively be round robin scheduled.
并结合流域洪水特性,对1998年6月大洪水重新进行了科学防洪调度分析,提出科学调度方案,以充分发挥水库的防洪作用。
Combining with the basin flood features, the authors analyzed again the "1998.6"flood scientific dispatch process to give full playing reservoir flood prevention action.
如何调度器时重新控制想要的吗?
表示处于禁用状态的调度程序,并提供重新启用调度程序处理的方法。
Represents the dispatcher when it is in a disable state and provides a means to re-enable dispatcher processing.
