APM code I've seen several versions of it, From 2.91b to Pix4flow 3.2.1 can be used to the latest 3.3.1, the different versions of the PID code are some differences, about his understanding of the PID code I will be in a separate article to chat, today I first talk about the Renesas G13 SCM platform to adjust the experience of PID, PID code is a transplant arducopte R_3.2.1RC1, you can go to github download. The process of tuning the PID reference Bo

First, using APM without a thread pool　APM allows the thread pool to invoke the specified callback method when the asynchronous operation completes. It uses very little resources and provides excellent performance, however, APM also allows three different ways to discover when an asynchronous operation is completed.First, if a thread calls the EndXxx method befor

APM (asynchrocous programming model) mode:To invoke a method asynchronously through a delegate class:1. Define a delegate type:delegate int Mydeletatetype (string s);2. Instantiate a delegate instance, constructing a function to be called asynchronously Funcavar del = new Mydeletatetype (Funca);int Funca (String a){Console.WriteLine (a);return 1;}Orvar del = new Mydeletatetype ((a) + = {Console.WriteLine (a); return 1;});3. Invoke the method asynchron

Use APM to perform computing-restricted asynchronous operations We can call any method through APM, but first, we need to define a method with the same signature as the method we want to call. Take the method of calculating the sum of 1 to n as an example (this is a computation intensive task that does not perform any I/O operations ). Private Static uint64 sum (uint64 N){Uint64 sum = 0;For (uint64 I = 1; I

WCF can directly return taskBelow the implementation code, not much nonsense, note the comment:Using system;using system.collections.generic;using system.linq;using system.text;using System.Threading;using System.threading.tasks;using system.web;using system.web.services.protocols;using System.Web.UI;using System.web.ui.webcontrols;namespace webapplication1{public partial class _default:page {protected Async V OID Page_Load (object sender, EventArgs e) {//This is not done directly with Asyncwebs

class. All these methods start with "end" and return an iasyncresult object, which has an asyncstate attribute, this attribute is very important because it can be used to pass any object we want to pass. These are actually asynchronous programming models (APM -- asynchronous programming model ). APM supports the following methods: Wait-until-done, polling, and method callback. However, after calling a seri

The APM encapsulation of WebService is Async, And the Await mode facilitates Asp. Net page calls, And asyncawait For Async and Await commands, Wcf can directly return the Task The implementation code below is not nonsense. Note the following: Using System; using System. collections. generic; using System. linq; using System. text; using System. threading; using System. threading. tasks; using System. web; using System. web. services. protocols; usin

specifically, the original function of the gcs_mavlink below libraries is parallel to the function of the gcs_mavlink.cpp placed under Copter/rover/plane. They are all layered applications based on the protocol package generated by the root XML file. The framework of the comb almost, the following will enter the actual combat, to see how the flow of data flows;Data flowThe source of APM is a little bit better, the task (only the senses) can give peop

causes performance degradation, it may be a database problem. We can find DBA to solve it. In this case, the difference between the NoSQL solution is that you can usually have a database cluster, so you need to know whether the problem is caused by a single node. DBA will check whether the access mode is well allocated to the cluster, or just assign it to a point in the cluster. It shows that the Cassandra server Node3 consumes more waiting and I/O time than other nodes. In fact, this analysis

Thanks to the recommendation of @penguinz, but also found a provider of application performance management services of domestic manufacturers: "listen to the cloud", read the People-Wu Yu write the trial notes, only to understand the application of foreign properties management company New Relic is the real APM daniel, product line coverage is very comprehensive, the function is very powerful, But indeed, as the man said, the visit was too s

This developer must want to know where the statement runs the special task and why it occurs.

In this case, the difference between the nosql solution is that you can

Reprint please explain.The number of launches of an application is undoubtedly an important test indicator for APM. But the number of Android launches takes into account an important factor. That's when you switch back to the front desk from the background. Is this a new startup?Friends and Newrelic as the world's 2 leaders in the data testing, the approach is similar. But the means of implementation are completely different.Newrelic and the implement

1. Timing CallbackEach flight control platform provides a 1khz timer that can be "registered" to obtain a 1khz timer function. All registered timers will be called sequentially. Invocation form: hal.scheduler->register_timer_process((Ap_hal::memberproc) (ap_baro_ms5611::_update));Ap_hal::memberproc () macro, the main function is to wrap up a C + + member function as a callback function. It is defined as follows:typedef void (*PROC) (void);Functor_typedef (Memberproc, void);
