offscreen dispatch

Bank Business Dispatch system First, the need to simulate the implementation of banking business scheduling system logic, the specific requirements are as follows: 1. There are 6 business windows in the Bank, 1-4 window is the normal window, window 5th is the Quick window, and the 6th window is the VIP window. 2. There are three types of customers: VIP customers, ordinary customers, fast customers (handling such as electricity and water bills, such as

; 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

Dispatch is a PHP small framework that can combine Dispatch and other frameworks to develop a very powerful and lightweight program. if you need it, you can refer to Dispatch as a small PHP framework. It does not give you complete MVC settings, but you can define URL rules and methods to better organize applications. This is perfect for APIs, simple sites, or pro

the order in which the methods are loaded.When a method is called, the JVM first checks that it is not a class method. If so, the method is found and executed directly from the class that called the method reference variable, and is no longer determined whether it is overridden (overwritten). If not, do other things (such as dynamic method queries)Some people may have a pat on the thigh, this is not the static/dynamic allocation of Java!A bit like, but not really, static

Description: These two days encountered some of the Java methods assigned to the problem, combined with their own books, Google, and the Caesar taught me to make a summary. Write method assignment refers to how the virtual machine determines which method should be executed! A lot of content can participate in this blog post in http://rednaxelafx.iteye.com/blog/652719: The explanations for many of the concepts in this article are excerpted from the posts above, so I'm not going to point it out.

related to the number of currently ready processes, so the time taken to find is O (n Level, n is the number of currently ready processes. Because of this, the execution time of the dispatch action is related to the current system load and cannot be given a limit, which is contrary to the requirement of real-time.In the new O (1) Schedule, this lookup process is decomposed into n steps, and each step takes an O (1) magnitude.The Prio_array contains a

Dispatch function is an important concept in the Windows Driver. The main function of the driver is to process I/O requests.It is handled in dispatch letters. All the I/O requests to the driver in user mode are converted from the operating system to an IRP data structure."Dispatch" to different dispatch letters. IRP an

The IRPTRACE tool Tracking IRP dispatch function (DISPATHC Funtion) is an important concept in Windows drivers. The main function of the driver is to handle I/O request, where most of the I/O requests are handled in the dispatch function. i/for all drivers in user modeo request. All of the operating systems are transformed into a data structure called an IRP, and different IRP data are dispatched to differe
