eXtremeDB HA synchronization procedure

Here is the description of synchronization procedure: 1. If values are equal, this means thatthe master and replica have the same database version and no synchronization Otherwise(if master’s and replica’s sequencer values are different), the masterinitiates the synchronization

PUN☀️七、网络同步：Object Synchronization

每个玩家控制的角色都有相同脚本，输入控制角色的命令，要确定哪个角色属于当前玩家，只执行那个角色的代码，比如摄像头控制代码、角色运动控制代码） 某玩家发送给其他玩家的消息（其他玩家减血、胜利等等） Object Synchronization Object Synchronization适合频繁同步的属性。 使用 PUN，我们可以很容易地使某些游戏对象“网络感知”。

【Java】解决Java报错：IllegalMonitorStateException in Synchronization

在Java编程中，IllegalMonitorStateException是一种常见的运行时异常，通常在使用同步代码块或方法时发生。它表示线程试图在没有持有相应监视器锁的情况下执行等待、通知或通知所有操作。正确处理IllegalMonitorStateException对于确保多线程应用程序的正确性和可靠性至关重要。本文将深入探讨IllegalMonitorStateException的产生原因，并提供具体的解决方案和最佳实践，帮助开发者更好地理解和解决这个问题。

区块链节点同步慢 Warning: Synchronization stalled

如何解决区块链节点同步慢的问题 摘要 在区块链世界中，节点同步慢是一个常见的问题，尤其是从国外节点同步数据时会遇到Warning: Synchronization stalled的警告。 场景描述 在运行区块链节点时，我们可能会看到如下警告： Warning: Synchronization stalled 这个警告通常出现在区块链节点从远程节点同步数据时，尤其是当这些远程节点位于国外

DAY67：阅读阅读Events、Synchronization和Device Management

Events Only the inter-stream synchronization capabilities of CUDA events are supported. It is up to the program to perform sufficient additional inter-thread synchronization, for example via Block Wide Synchronization The cudaDeviceSynchronize() function does not imply intra-block synchronization In particular, without explicit synchronization via a __syncthreads() directive the calling thread can For example if multiple threads within a block are each launching work and synchronization is desired

Java并发编程实战系列15之原子遍历与非阻塞同步机制(Atomic Variables and Non-blocking Synchronization)

近年来，在并发算法领域的大多数研究都侧重于非阻塞算法，这种算法用底层的原子机器指令来代替锁来确保数据在并发访问中的一致性，非阻塞算法被广泛应用于OS和JVM中实现线程/进程调度机制和GC以及锁，并发数据结构中。 与锁的方案相比，非阻塞算法都要复杂的多，他们在可伸缩性和活跃性上（避免死锁）都有巨大的优势。 非阻塞算法，顾名思义，多个线程竞争相同的数据时不会发生阻塞，因此他能在粒度更细的层次上进行协调，而且极大的减少调度开销。 15.1 锁的劣势 独占，可见性是锁要保证的。 许多JVM都对非竞争的锁获取和释放
