#Gosync software code
Remember, easy-to-understand code models are always more down-to-earth than esoteric dazzling skills. NVIDIA G-SYNC is groundbreaking new display technology that delivers the smoothest and fastest gaming experience ever. Q.itemAdded.L = &sync.Mutexįinally, although the potential problems of sync.Cond are listed in the above discussion, if the developer can consider the above issues in use, for the implementation of the monitor model, in the semantic logic of the code Above, the use of sync.Cond will be easier to understand and maintain than the channel mode. Readers who are in contact for the first time may not quite understand, so let's take a look at the demo code example in "Rethinking Classical Concurrency Patterns" type Item = int It can block multiple goroutines at the same time until another goroutine changes the condition variable and notify one or more blocked goroutines to wake up. They both require manufacturer-specific hardware in the monitor that works in conjunction with their. The condition variable is isolated from the shared data. The first serious levels of hardware-based adaptive refresh are G-Sync and FreeSync Premium. In concurrent programming(also known as parallel programming), a monitor is a synchronization construct that allows threads to have both mutual exclusion and the ability to wait (block) for a certain condition to become false.įor Cond, it implements a condition variable, which is the point of waiting and notification between goroutines. Sync.Cond literally means the synchronization condition variable, which implements a monitor mode.
For most sync.Cond, 061795b72c8654 should be the most unfamiliar, this article will take a closer look. To write a qualified Go program, the above concurrency primitives must be mastered. Currently, the enablement list of the sync package includes: atomic operations under sync.atomic sync.Map concurrent security map, mutexes and read-write locks provided by sync.Mutex and sync.RWMutex sync.Pool multiplexed object pool, sync.Once singleton mode, sync.Waitgroup Mode, monitor mode of sync.Cond Of course, in addition to the sync package, there are channel and context with higher encapsulation levels. Go language through the go keyword to open goroutine so that developers can easily implement concurrent programming, and the effective operation of concurrent programs, often can not do without the escort of the sync package.
