运行上述代码,你应该会看到异步操作在子线程中成功执行,而不会抛出RuntimeError: there is no current event loop in thread 'thread-8'的错误。 通过显式地在子线程中设置事件循环,我们确保了异步操作能够在一个具有事件循环的上下文中执行,从而避免了错误。

*/publicvoidset(Tvalue){Thread t=Thread.currentThread();ThreadLocalMap map=getMap(t);if(map!=null)map.set(this,value);elsecreateMap(t,value);} 在这个方法内部我们看到,首先通过getMap(Thread t)方法获取一个和当前线程相关的ThreadLocalMap,然后将变量的值设置到这个ThreadLocalMap对象中,当然如果获取...
I'm going to introduce my new comming demon called "Another Fluttershy". It is the sequel of the level "Fluttershy Effect". In addition, this is also a remake of AnotherCircles. After finished, this level will be verified by me. These are the screenshots below:...

I noticed that dxgkrnl always run on Thread 0, no matter what. However after checking some documentation i realized that large PCI-E slots on this mainboard are connected to Numa node 1.Is it possible somehow to run dxgkrnl.sys on Thread 8 instead (Core0 on NUMA1)? Solved! Go to ...
Dxgkrnl on thread 8? I have x399M with Threadripper 1900x, paired with Radeon VII. I noticed that dxgkrnl always run on Thread 0, no matter what. However after checking some documentation i realized that large PCI-E slots on this mainboard are connected to Numa node 1. I confirmed this...
一般来说,多线程技术涉及三种方法,其中第一种是使用计时器模块QTimer;第二种是使用多线程模块QThread;最后是使用事件处理的功能。 1、QTimer计时器类 如果要在应用程序中周期性地进行某项操作,比如周期性地检测主机的CPU值,则需要用到QTimer(定时器),QTimer类提供了重复的和单次的定时器。要使用定时器,需要先...
RT-thread---信号量 信号量:用于解决线程间同步问题的内核对象,线程可以获取或释放它,从而达到同步或互斥的目的。(互斥量只能由持有线程释放,而信号量则可以由任何线程释放) 在rtt中,信号量分为计数型信号量和二值信号量(作为锁使用)。 计数型信号量的值可表示...
thread_concurrency 参数用于设置 MySQL 服务器的线程并发度,它控制了 MySQL 服务器中同一时间可以并发执行的线程数目。具体来说,它限制了 MySQL 服务器中正在执行的线程的数量,以避免因为线程过多导致的系统资源消耗过高、线程之间互相竞争导致性能下降等问题。
