timer reset in separate go routine

阅读更多关于 timer reset in separate go routine

问题 In the following scenario a network entity always waits for a TimeOutTime seconds before doing a particular task X . Assume this time as TimerT . During this wait of TimeOutTime seconds if the entity receives a set of external messages, it should reset the same TimerT to TimeOutTime again. If no external messages are received the expected behaviour is as follows: Timer Expired Do task X Reset the Timer again to TimeOutTime (by reset I mean, stop the timer and start over again) To simulate the

What is the simplest way to run a timer-triggered Azure Function locally once?

阅读更多关于 What is the simplest way to run a timer-triggered Azure Function locally once?

问题 I have a few C# Azure Functions that run on a schedule using timer triggers. I've set them up like so, where %TimerSchedule% refers to a cron expression in the app settings: public static void Run([TimerTrigger("%TimerSchedule%")]TimerInfo myTimer, TraceWriter log) During development, I often want to run the functions locally using Azure Functions Tools for Visual Studio + Azure Functions Core Tools. But when I hit F5 to debug the function locally it (usually) doesn't run immediately. Instead

Creating an awaitable System.Timers.Timer

问题 I had an idea about creating a timer that can be awaited, instead of raising events. I haven't thought of any practical applications yet, and may not be something terribly useful, but I would like to see if it's at least doable as an exercise. This is how it could be used: var timer = new System.Timers.Timer(); timer.Interval = 100; timer.Enabled = true; for (int i = 0; i < 10; i++) { var signalTime = await timer; Console.WriteLine($"Awaited {i}, SignalTime: {signalTime:HH:mm:ss.fff}"); } The

CUDA: CUtil timer - confusion on elapsed time

阅读更多关于 CUDA: CUtil timer - confusion on elapsed time

问题 When I assess my program, I saw that at some point I get up to 100msec time lapse. I have searched every operation, but individually no operation was taking this time. Then I have noticed that wherever I do place cudaThreadSynchronize call, the first call takes 100 msec. Then I have written such an example below. When cudaThreadSynchronize is called at the first line, the elapsed time value at the end is found less than 1 msec. But if it is not called then it takes 110msec on average. int

问题 I still have the problem when the count reaches 3, the reset function only stops it, but the count is not set to 0. I use the reset function with a button, it works perfectly. i would like to understand it and hope someone knows the reason for it? import SwiftUI import Combine import Foundation class WaitingTimerClass: ObservableObject { @Published var waitingTimerCount: Int = 0 var waitingTimer = Timer() func start() { self.waitingTimer = Timer.scheduledTimer(withTimeInterval: 1.0, repeats:

Timer和TimeTask简介

Timer和TimeTask简介 Timer是一种线程设施，用于安排以后在后台线程中执行的任务。可安排任务执行一次，或者定期重复执行，可以看成一个定时器，可以调度TimerTask。TimerTask是一个抽象类，实现了Runnable接口，所以具备了多线程的能力。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 import java . util . TimerTask ; public class MyTask extends TimerTask { private int id ; public MyTask ( int id ) { this . id = id ; } public void run ( ) { System . out . println ( "线程" + id + ":正在执行" ) ; //System.gc(); } } 然后主程序代码为： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 import java . util . Date ; import java . util . Timer ; public class Test { public static void main ( String [ ] args ) { Timer timer = new Timer (

How to know elapsed time during execution of system command in Matlab?

问题 I have a Matlab code that runs a system script. The script may be stopped due to the command runs. I want to know if there is a way that the program knows if it has taken a long time and do something else. Here is the code: tic; [status,cmdout]=system(iperfcmd); % The program can be blocked here toc; % I want to know if it has taken a long time (like 5 seconds) for the system call and kill it. 回答1: How about performing the system call asynchronously (https://uk.mathworks.com/help/parallel
