Abstract
Coordination of execution of multiple Process (进程) or Thread in a system to ensure that they access shared resources in a controlled and predictable manner The table below lists some common synchronisation methods
Synchronization Method Usage Advantages Disadvantages Example Use Case Barrier (屏障) Synchronise threads at a point Simple, ensures synchronisation Limited use cases Parallel computing phases Condition Variable (条件变量) Wait for condition with mutex Handles complex conditions Complex, potential Race Condition (竞态条件) Producer-consumer problems Mutex (互斥体) Protect shared data Simple, effective Contention, potential Deadlock (死锁) Critical sections Semaphore (信号量) Control access to resources Flexible, versatile Complex, potential errors Resource pools Spinlock Busy Waiting for short periods Low overhead for short waits Inefficient for long waits Low-level programming
