This is a different approach in need of CPU scheduling. According to this algorithm when the CPU is free, the process will be assigned which will have the smallest next CPU burst. SJF is optimal which means it
Developing CPU scheduling algorithms in operating system and understanding effect of various algorithms in practice can be difficult and deadly because of the requirement to update the operating system and test operating system kernel code and quantity the succeeding presentation of operating system on a...
CPU schedulingis the process of deciding which process will own the CPU to use while another process is suspended. The main function of the CPU scheduling is to ensure that whenever the CPU remains idle, the OS has at least selected one of the processes available in the ready-to-use line....

You can usenode affinity schedulingto schedule the configured pods to the nodes where thestaticpolicy is enabled. In this way, the pods can exclusively use the CPU resources.

在像MS DOS这样的单编程系统中,当进程等待任何I/O操作完成时,CPU仍然是空闲的。 这是一个开销,因为它浪费时间并导致饥饿问题。 但是,在多程序系统中,CPU在进程的等待时间内不会保持空闲状态,而是开始执行其他进程。 操作系统必须定义CPU将被给予哪个进程。
