Transferred from: http://www.cnblogs.com/zfyouxi/p/4504042.htmlThis article is about the kernel of the process scheduling mechanism, process scheduling is an important task of the kernel, by the scheduler completed.Process statusThe entity that the kernel scheduler dispatches (KSE, Kernal Schedule Entry) are processes and threads. The kernel must know the state of all processes and threads, for example, it

Process scheduling: Scheduling in the operating system refers to a resource allocation.Scheduling algorithm refers to the resource allocation algorithm according to the resource allocation policy of the system.The operating system manages the limited resources of the system, and when there are multiple processes (or requests made by multiple processes) to use these resources, because of the limited resource

read/write head, which is called the rotational delay time; It takes time to actually transfer the information between the disk and the memory, which is called the transfer time. The total time of a disk service is the sum of these three.?? To make the disk service as fast as possible, the operating system needs to provide an appropriate scheduling algorithm to improve the average time of the disk service.?? The process needs to exchange information

HadoopYARN supports both memory and CPU scheduling (by default, only memory is supported. If you want to further schedule the CPU, You need to configure it yourself ), this article describes how YARN schedules and isolates these resources. In YARN, resource management is completed by ResourceManager and NodeManager. Hadoop YARN supports both memory and CPU scheduling (only memory is supported by default. If

. println ("consumption" + (end-start) + "ms "); }// Consume 1001 MS}We have seen the advantages of the thread! It takes 10 S for a single thread and 1 S for 10 threads. Fully utilizes system resources for parallel computing. It may be a misunderstanding whether the increasing number of threads is more efficient. The more threads, the higher the processing performance. This is an error. The paradigm should be appropriate. It is not good if it passes through. We need to popula

On a non-SMP system, each process assigns a uniqueSet the CPU time slice to achieve the execution purpose, it looks like multiple tasks are running at the same time. Nt kernelIt also takes thread scheduling as the core, so th

One system calls do_fork ()1. The current process calls fork () to create a sub-process and enters the kernel2. The current process is divided into more than half of the time slices to the sub-process,3 if the remaining time slice of the current process is 0, set need_sched = 1,4. Exit from the system call5 to ret_from_sys_call6 To ret_with_reschedule7. The current process requires scheduling and jumps to reschedule.8 call schedule ()9 schedule () pro
