The scheduling function is quite simple when it comes to the CFS portion.
就CFS部分而言,调度函数非常简单。
Thus there is disagreement in the medical community as to whether CFS is a distinct disease.
因此医学界对于慢性疲劳综合癥是否为一种确定的疾病尚存争论。
Writing in the Public Library of Science, Otto Erlwein of Imperial College, London, and his colleagues report that they are unable to find XMRV in any of almost 200 CFS patients in Britain.
伦敦帝国理工学院的Ot toErlwein(供稿于公共科学图书馆)和他的同事报告说,他们在英国约200个CFS患者身上并未发现XMRV。
Instead of all tasks being treated fairly uniformly, CFS introduces groups to account for this behavior.
不是所有任务都会被统一公平对待,CFS引入了组来处理这种行为。
The main idea behind the CFS is to maintain balance (fairness) in providing processor time to tasks.
CFS背后的主要想法是维护为任务提供处理器时间方面的平衡(公平性)。
Note that CFS has no real notion of time slices for preemption, because the preemption time is variable.
注意CFS没有真正的时间切片概念用于抢占,因为抢占时间是可变的。
CFS doesn「t use priorities directly but instead USES them as a decay factor for the time a task is permitted to execute.
CFS不直接使用优先级而是将其用作允许任务执行的时间的衰减系数。
CFS operates at the user level, communicating with the kernel through Network File System (NFS).
CFS工作于用户级,通过网络文件系统(NFS)与内核进行通信。
Group scheduling enables CFS to be fair to users a and b, rather than being fair to all 50 jobs running in the system.
组调度使CFS能够对用户a和用户B进行公平调度,而不是对系统中运行的50个作业进行公平调度。
Furthermore, at any point, CFS promises to run sched_period ahead because the task last scheduled would run again within that window.
此外,在任何时刻,CFS都承诺超前运行sched _ period,因为最后执行调度的任务将在这个时限内再次运行。
Another interesting aspect of CFS is the concept of group scheduling (introduced with the 2.6.24 kernel).
CFS另一个有趣的地方是组调度概念(在2.6.24内核中引入)。
But, as doctors are often quick to point out, CFS is real and disabling no matter the cause.
但是医生们很快指出不管什么原因造成CFS,它的癥状是真实存在的并会导致患者伤残。
CFS does not use a priority array, and it does away with the array-switching artifact of the vanilla scheduler. A few important differences between RSDL and CFS.
CFS没有使用优先级数组,它去掉了vanilla调度程序的数组切换工件。
A better understanding of CFS is surely needed.
更好地理解慢劳癥是确实有必要的。
Note: This example USES the standard CFS (as invoked through schedule via linsched_run_sim).
注意:此示例使用标準CFS(如通过linsched _ run_sim调用schedule )。
CFS does not consider a task to be a sleeper if it sleeps for 「very」 short time-a short sleeper might be entitled to some bonus time, but never more than it would have had had it not slept.
如果某个任务休眠时间「非常短」,那么CFS不会将该任务视为休眠任务—短暂休眠的进程可能会获得一些额外时间,但是决不会超过它的未休眠时间。
It seems likely that the causes of CFS will continue to be a subject of controversy for a while yet.
似乎导致CFS的原因在短时间内将继续是争论的主题。
But rather than maintain the tasks in a run queue, as has been done in prior Linux schedulers, the CFS maintains a time-ordered red-black tree (see Figure 1).
但是与之前的Linux调度器不同,它没有将任务维护在运行队列中,CFS维护了一个以时间为顺序的红黑树(参见图1)。
This way CFS tries for the ideal situation where wait_runtime is zero!
通过这种方式,CFS努力实现一种理想状态,即wait _ runtime值为0 !
The CFS scheduling module uses it for group scheduling, while the scheduling module for a real-time task does not use it.
CFS调度模块使用它进行组调度,而用于实时任务的调度模块则不会使用这个函数。
Let」s dig into the CFS to see how it operates at a high level.
我们来剖析一下CFS,从较高的层次上看看它是如何运行的。
When they ran one PCR assay that had been used in the original Science report, they found 5% of both CFS and control samples tested positive for XMRV.
当他们用PCR方法检测分析原始Science报道上的样品时,发现CFS样品和对照组都有5%的XMRV检测阳性率。
Monday's paper is the latest in a series of reports about a possible link between CFS and a virus.
周一的报告是一系列有关慢性疲劳综合癥与病毒可能联系的研究报告中的最新一份。
