一旦内核调度进程执行，它就设置栈和堆，前者从用户空间的顶部向下增长，后者从可执行映像的尾部向上增长。
Once the kernel schedules the process for execution, it sets the stack to grow down from the top of user space, and the heap to grow up from the end of the executable image.
在设置为1时，调度器尝试在核上尽可能少的超线程上调度进程，让其他超线程可以空闲，进而通过空闲C 状态节省电力。
When it is set to 1, the scheduler tries to schedule processes to as few hyperthreads on a core as possible so that the others can go idle and in turn save power through idle C states.
在此过程中，通常也假定存在内存管理或进程调度特性。
In that process, often the features of memory management or process scheduling are assumed.
很多应用程序都假定由操作系统提供内存管理功能或进程调度功能。
Many applications assume the memory management features, or process scheduling features, provided by the OS.
在对进程的内核线程进行绑定之后，它们将会被调度运行于指定的处理器。
Once kernel threads of the process are bound, they'll always be scheduled to run on the selected processor.
内核调度程序使用这种方法实现由调度模块管理的进程的负载平衡。
The core scheduler USES this method to load-balance processes managed by the scheduling module.
进程的执行由底层虚拟机调度。
Process execution is scheduled by the underlying virtual machine.
调度实体可能与进程没有关联。
内核使用收集的CPU 使用量数据，可以根据优先级、当前 CPU 使用量和 CPU 限制调度或撤消运行进程。
The CPU usage thus gathered is used by the kernel, which may schedule or de-schedule a process based on its priority, current CPU usage, and CPU limits.
最后，disp栏指明了在PTT工具收集统计数据的时间间隔内进程被调度的次数。
Finally, the disp column indicates the number of times the process was dispatched during the interval that the PTT tool collected statistics.
TASK_RUNNING：进程当前正在运行，或者正在运行队列中等待调度。
TASK_RUNNING: the process is either running on CPU or waiting in a run queue to get scheduled.
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.
应该关闭所有不重要的后台进程，并避免调度的进程(比如屏幕保护和病毒扫描程序)在基准测试期间启动。
And you likely want to shut down all nonessential background processes, as well as prevent scheduled processes (such as screen savers and virus scanners) from kicking in during benchmarking.
此调度器添加和删除进程效率很高（具有保护结构的锁）。
This scheduler was efficient for adding and removing processes (with a lock to protect the structure).
记住，您必须是超级用户才能为进程指定更高的调度优先级，或者说让它们的nice值更低。
Remember that you have to be the superuser to give your processes higher scheduling priority and make them less nice.
清单1中的ni列展示了调度优先级或者说每个进程的niceness。
The ni column in Listing 1 above, shows the scheduling priority or niceness of each process.
它将调度实体(进程)放入红黑树中，并对nr_running变量加1。
It puts the scheduling entity (process) into the red-black tree and increments the nr_running variable.
使用nice或renice优化调度程序——可帮助您为运行进程分配不同的优先级，以避免占用大量CPU资源。
Tuning scheduler using nice or renice — This helps you to assign different priorities to running processes to prevent CPU hogs.
进程被调度的次数(或者说是内核调度子例程为那个进程释放CPU的次数)。
Number of times that the process was dispatched (or how many times the kernel dispatch subroutine relinquished the CPU to that process).
垃圾收集器使用非阻塞算法加快并发和平行的垃圾搜集；调度器使用非阻塞算法有效地调度线程和进程，实现内在锁。
The garbage collector uses them to accelerate concurrent and parallel garbage collection; the scheduler uses them to efficiently schedule threads and processes and to implement intrinsic locking.
本节将阐述如何测试调度后台进程的高可用性。
This section shows how to test the high availability of the scheduling daemon.
您可以配置应用程序/批处理服务器域以及进程调度器。
You can configure the application/batch server domains and process scheduler.
TORQUE系统包含三个守护进程：服务器、调度器和作业执行器。
The TORQUE system includes three daemon processes: the server, the scheduler, and the job executor.
负载平衡：调度器会降低那些超出处理器负载能力的进程的优先级。
Load balancing: the scheduler will decrease the priority of any process that generates more load than the processor can handle.
当新的操作系统在KVM上启动时（通过一个称为 kvm的实用程序），它就成为宿主操作系统的一个进程，因此就可以像其他进程一样调度它。
When a new operating system is booted on KVM (through a utility called kvm), it becomes a process of the host operating system and therefore scheduleable like any other process.
这样做的好处是可以覆盖系统内建调度器，迫使一个进程只在指定的CPU 上运行。
The advantage of doing this is to override the system's built-in scheduler to force a process to run only on specified CPUs.
SSI解决方案会修改内核的几乎所有部分：进程管理、文件系统、内存 管理、调度器，等等。通过不加修改地运行内核进程，模拟器简化了部署工作。
SSI solutions modify almost every area of kernel: process management, filesystem, memory management, scheduler, etc. Emulators simplify the deployment by letting the kernel processes run unchanged.
