这将允许更多的延迟隐藏和更少的指令管道摊位,和代码运行更快。
This allows more latency hiding and less instruction pipeline stalls, and the code runs faster as a result.
这样,线程之间互相协作,隐藏了各自的延迟时间。
In this way, the threads work with one another to hide each other's latency.
多线程计算不仅用来实现细粒度的并行,合理的调度策略还有助于隐藏通信延迟。
Multithreads can not only implement fine-grain parallelism effectively, but also be helpful to hide communication latency with reasonable scheduling strategies.
