Scheduler is only a part of the scheduling process, process scheduling is a very complex process, requiring multiple systems to work together to complete. The focus of this article is only the scheduler, whose main task is to select the most appropriate one in all RUNNING processes. As a general-purpose operating system, the Linux
1. Introduction to Kubernetes Scheduler
Kubernetes Scheduler runs at the master node, its core function is to listen to the apiserver to get the pod that is podspec.nodename empty, and then create a binding for each such pod that the pod should be dispatched to on which node.
From where to read the pod that hasn't been scheduled yet. Of course it's apiserver. How do you know pod is not scheduled? It asks t

I re-read the CFS scheduler today, so I can't help writing another article about CFs. The running time of the CFS scheduler is 0 (logn ), in the past, the running time of the scheduler was O (1). Does this mean that the efficiency of CFS is worse than that of O (1? This is not the case. We know that the running queues under the CFS
The purpose of the Hadoop Scheduler is to assign the idle resources in the system to a job by a certain policy. The Scheduler is a pluggable module that allows the user to design the scheduler according to their actual application requirements. There are three types of schedulers common in Hadoop, namely:1. Queue-based FIFO (advanced first-out) The default resou

In hadoop, the scheduler is a pluggable module. You can design a scheduler based on your actua
1.1 schedule events in the game
One scheduling can effectively help the following game technologies, including physical simulation, character movement, collision detection, AI in the game, and rendering. One of the key issues with all these technologies is time. When hundreds of different objects and processes need to be updated at different times, many of these simulation technologies become very complex.
An important capability of the scheduler is t

A real-time application can be used as a standalone task when using an RTOS. Each task has its own operating environment, independent of other tasks in the system or the RTOS scheduler. There can be only one task running at any point in time, which is determined by the RTOS scheduler, so the RTOS scheduler will repeatedly turn on and off each task
