; Getqueueservice design idea may be that each Iattemperengine interface has a cqueueservice behind, from the analysis can be seen in the future, this idea is the key to understanding the whole kernel. The dispatch engine should be a message rollup (messages generated from each engine) and then distributed to Iattemperenginesink. Because there's nothing in the code to see about Itimersink isocketsink and stuff like that, The whole message is an engine

-related load Balancing"). int Prev_cpu_load[nr_cpus] Record the load state on each CPU when load is balanced (the nr_running value in the ready queue at this point) to analyze the load situation (see "Scheduler-related load Balancing"). ) atomic_t *node_nr_running; int Prev_node_load[max_numnodes] These two properties are valid only under the NUMA architecture, recording the number of ready processes on each NUMA node and the load at the time of the last load balancing operation (see "Schedulin

based on the new URL. There is a typical feature of redirection, that is, when a request is redirected, the URL displayed on the browser is often no longer the one requested at the beginning. This is the origin of redirection. A typical application of HTTP redirection is to prevent repeated submission of forms. The principle is: if a user information editing page is used, the form is submitted to saveuser through post. action. After the request is submitted, a redirected response can be returne

Java design pattern (3) Visitor pattern and Application in Multi-Dispatch scenariosThe basic concept of Visitor encapsulates operations that act on each element in the data structure. Different operations can be implemented with the help of the new visitor, reducingCouplingVisitors canData StructureAndData OperationsDecoupling makes it unnecessary to modify the data structure or modify the original operation for the added operations on the data struct

Design Summary Network Office is the trend of modern enterprise development. This paper mainly expounds the function module of the transceiver management system based on B/s structure and how to use ASP and SQL Server to solve some related technologies, including the security of the system. Keywords network office; b/S structure; receipt and dispatch management system; ASP technology; security Introduction Traditional manual Office is unable to mee

First, introduce several concepts: GCD, queue, serial, parallel, synchronous, asynchronous. GCD (Grand Central Dispatch ): The Great Apple developed a multi-core multi-thread solution. Is a C language-based underlying API Defining tasks with blocks is flexible and convenient to use. Provides more control capabilities and underlying functions not available in the Operation queue The basic idea of GCD is to put the operation s

In the standalone interrupt stack mode, if

You know, in spring MVC, you can configure spring in both Applicationcontext.xml and dispatch-servlet.xml, so what's the difference between them: Let's take a look at the Spring official documentation: Spring lets you define multiple contexts in a parent-child hierarchy. The applicationcontext.xml defines the beans for the "root webapp context" and i.e. the context associated with the WebApp. The spring-servlet.xml (or whatever else call it) defines

The previous article has described the configuration of quartz.net, the use of the and cron expression expressions. Basically, the timing of the task in the background is completed, and the relevant job can be executed correctly according to the execution plan.Then, if the task needs to be updated, stop a task? Can not be on the server to change the configuration of the relevant job. Therefore, Quartz.net also provides us with a method of remote dispatch
